Cadmium in General Industry 29 CFR 1910.1027

§ 1910.1027 Cadmium.
(a) Scope. This standard applies to all occupational exposures to cadmium and cadmium compounds, in all
forms, and in all industries covered by the Occupational Safety and Health Act, except the constructionrelated industries, which are covered under 29 CFR 1926.63.
(b) Definitions. Action level (AL) is defined as an airborne concentration of cadmium of 2.5 micrograms per
3
cubic meter of air (2.5 µg/m ), calculated as an 8-hour time-weighted average (TWA).
Assistant Secretary means the Assistant Secretary of Labor for Occupational Safety and Health, U.S.
Department of Labor, or designee.
Authorized person means any person authorized by the employer and required by work duties to be present
in regulated areas or any person authorized by the OSH Act or regulations issued under it to be in regulated
areas.
Director means the Director of the National Institute for Occupational Safety and Health (NIOSH), U.S.
Department of Health and Human Services, or designee.
Employee exposure and similar language referring to the air cadmium level to which an employee is
exposed means the exposure to airborne cadmium that would occur if the employee were not using
respiratory protective equipment.
Final medical determination is the written medical opinion of the employee's health status by the examining
physician under paragraphs (l)(3)-(12) of this section or, if multiple physician review under paragraph (l)(13)
of this section or the alternative physician determination under paragraph (l)(14) of this section is invoked, it
is the final, written medical finding, recommendation or determination that emerges from that process.
High-efficiency particulate air (HEPA) filter means a filter capable of trapping and retaining at least 99.97
percent of mono-dispersed particles of 0.3 micrometers in diameter.
Regulated area means an area demarcated by the employer where an employee's exposure to airborne
concentrations of cadmium exceeds, or can reasonably be expected to exceed the permissible exposure
limit (PEL).
This section means this cadmium standard.
(c) Permissible Exposure Limit (PEL). The employer shall assure that no employee is exposed to an
3
airborne concentration of cadmium in excess of five micrograms per cubic meter of air (5 µg/m ), calculated
as an eight-hour time-weighted average exposure (TWA).
(d) Exposure monitoring —(1) General. (i) Each employer who has a workplace or work operation covered
by this section shall determine if any employee may be exposed to cadmium at or above the action level.
(ii) Determinations of employee exposure shall be made from breathing zone air samples that reflect the
monitored employee's regular, daily 8-hour TWA exposure to cadmium.
(iii) Eight-hour TWA exposures shall be determined for each employee on the basis of one or more personal
breathing zone air samples reflecting full shift exposure on each shift, for each job classification, in each
work area. Where several employees perform the same job tasks, in the same job classification, on the
same shift, in the same work area, and the length, duration, and level of cadmium exposures are similar, an
employer may sample a representative fraction of the employees instead of all employees in order to meet
this requirement. In representative sampling, the employer shall sample the employee(s) expected to have
the highest cadmium exposures.

(2) Specific. (i) Initial monitoring. Except as provided for in paragraphs (d)(2)(ii) and (d)(2)(iii) of this section,
the employer shall monitor employee exposures and shall base initial determinations on the monitoring
results.
(ii) Where the employer has monitored after September 14, 1991, under conditions that in all important
aspects closely resemble those currently prevailing and where that monitoring satisfies all other
requirements of this section, including the accuracy and confidence levels of paragraph (d)(6) of this section,
the employer may rely on such earlier monitoring results to satisfy the requirements of paragraph (d)(2)(i) of
this section.
(iii) Where the employer has objective data, as defined in paragraph (n)(2) of this section, demonstrating that
employee exposure to cadmium will not exceed the action level under the expected conditions of
processing, use, or handling, the employer may rely upon such data instead of implementing initial
monitoring.
(3) Monitoring Frequency (periodic monitoring). (i) If the initial monitoring or periodic monitoring reveals
employee exposures to be at or above the action level, the employer shall monitor at a frequency and
pattern needed to represent the levels of exposure of employees and where exposures are above the PEL
to assure the adequacy of respiratory selection and the effectiveness of engineering and work practice
controls. However, such exposure monitoring shall be performed at least every six months. The employer, at
a minimum, shall continue these semi-annual measurements unless and until the conditions set out in
paragraph (d)(3)(ii) of this section are met.
(ii) If the initial monitoring or the periodic monitoring indicates that employee exposures are below the action
level and that result is confirmed by the results of another monitoring taken at least seven days later, the
employer may discontinue the monitoring for those employees whose exposures are represented by such
monitoring.
(4) Additional Monitoring. The employer also shall institute the exposure monitoring required under
paragraphs (d)(2)(i) and (d)(3) of this section whenever there has been a change in the raw materials,
equipment, personnel, work practices, or finished products that may result in additional employees being
exposed to cadmium at or above the action level or in employees already exposed to cadmium at or above
the action level being exposed above the PEL, or whenever the employer has any reason to suspect that
any other change might result in such further exposure.
(5) Employee Notification of Monitoring Results. (i) The employer must, within 15 working days after the
receipt of the results of any monitoring performed under this section, notify each affected employee of these
results either individually in writing or by posting the results in an appropriate location that is accessible to
employees.
(ii) Wherever monitoring results indicate that employee exposure exceeds the PEL, the employer shall
include in the written notice a statement that the PEL has been exceeded and a description of the corrective
action being taken by the employer to reduce employee exposure to or below the PEL.
(6) Accuracy of measurement. The employer shall use a method of monitoring and analysis that has an
accuracy of not less than plus or minus 25 percent (±25%), with a confidence level of 95 percent, for
airborne concentrations of cadmium at or above the action level, the permissible exposure limit (PEL), and
the separate engineering control air limit (SECAL).
(e) Regulated areas —(1) Establishment. The employer shall establish a regulated area wherever an
employee's exposure to airborne concentrations of cadmium is, or can reasonably be expected to be in
excess of the permissible exposure limit (PEL).
(2) Demarcation. Regulated areas shall be demarcated from the rest of the workplace in any manner that
adequately establishes and alerts employees of the boundaries of the regulated area.
(3) Access. Access to regulated areas shall be limited to authorized persons.

(4) Provision of respirators. Each person entering a regulated area shall be supplied with and required to
use a respirator, selected in accordance with paragraph (g)(2) of this section.
(5) Prohibited activities. The employer shall assure that employees do not eat, drink, smoke, chew tobacco
or gum, or apply cosmetics in regulated areas, carry the products associated with these activities into
regulated areas, or store such products in those areas.
(f) Methods of compliance —(1) Compliance hierarchy. (i) Except as specified in paragraphs (f)(1) (ii), (iii)
and (iv) of this section the employer shall implement engineering and work practice controls to reduce and
maintain employee exposure to cadmium at or below the PEL, except to the extent that the employer can
demonstrate that such controls are not feasible.
(ii) Except as specified in paragraphs (f)(1) (iii) and (iv) of this section, in industries where a separate
engineering control air limit (SECAL) has been specified for particular processes (See Table 1 in this
paragraph (f)(1)(ii)), the employer shall implement engineering and work practice controls to reduce and
maintain employee exposure at or below the SECAL, except to the extent that the employer can
demonstrate that such controls are not feasible.

(iii) The requirement to implement engineering and work practice controls to achieve the PEL or, where
applicable, the SECAL does not apply where the employer demonstrates the following:
(A) The employee is only intermittently exposed; and
(B) The employee is not exposed above the PEL on 30 or more days per year (12 consecutive months).
(iv) Wherever engineering and work practice controls are required and are not sufficient to reduce employee
exposure to or below the PEL or, where applicable, the SECAL, the employer nonetheless shall implement
such controls to reduce exposures to the lowest levels achievable. The employer shall supplement such

controls with respiratory protection that complies with the requirements of paragraph (g) of this section and
the PEL.
(v) The employer shall not use employee rotation as a method of compliance.
(2) Compliance program. (i) Where the PEL is exceeded, the employer shall establish and implement a
written compliance program to reduce employee exposure to or below the PEL by means of engineering and
work practice controls, as required by paragraph (f)(1) of this section. To the extent that engineering and
work practice controls cannot reduce exposures to or below the PEL, the employer shall include in the
written compliance program the use of appropriate respiratory protection to achieve compliance with the
PEL.
(ii) Written compliance programs shall include at least the following:
(A) A description of each operation in which cadmium is emitted; e.g., machinery used, material processed,
controls in place, crew size, employee job responsibilities, operating procedures, and maintenance
practices;
(B) A description of the specific means that will be employed to achieve compliance, including engineering
plans and studies used to determine methods selected for controlling exposure to cadmium, as well as,
where necessary, the use of appropriate respiratory protection to achieve the PEL;
(C) A report of the technology considered in meeting the PEL;
(D) Air monitoring data that document the sources of cadmium emissions;
(E) A detailed schedule for implementation of the program, including documentation such as copies of
purchase orders for equipment, construction contracts, etc.;
(F) A work practice program that includes items required under paragraphs (h), (i), and (j) of this section;
(G) A written plan for emergency situations, as specified in paragraph (h) of this section; and
(H) Other relevant information.
(iii) The written compliance programs shall be reviewed and updated at least annually, or more often if
necessary, to reflect significant changes in the employer's compliance status.
(iv) Written compliance programs shall be provided upon request for examination and copying to affected
employees, designated employee representatives as well as to the Assistant Secretary, and the Director.
(3) Mechanical ventilation. (i) When ventilation is used to control exposure, measurements that demonstrate
the effectiveness of the system in controlling exposure, such as capture velocity, duct velocity, or static
pressure shall be made as necessary to maintain its effectiveness.
(ii) Measurements of the system's effectiveness in controlling exposure shall be made as necessary within
five working days of any change in production, process, or control that might result in a significant increase
in employee exposure to cadmium.
(iii) Recirculation of air. If air from exhaust ventilation is recirculated into the workplace, the system shall
have a high efficiency filter and be monitored to assure effectiveness.
(iv) Procedures shall be developed and implemented to minimize employee exposure to cadmium when
maintenance of ventilation systems and changing of filters is being conducted.

(g) Respiratory protection —(1) General. For employees who use respirators required by this section, the
employer must provide each employee an appropriate respirator that complies with the requirements of this
paragraph. Respirators must be used during:
(i) Periods necessary to install or implement feasible engineering and work-practice controls when employee
exposure levels exceed the PEL.
(ii) Maintenance and repair activities, and brief or intermittent operations, for which employee exposures
exceed the PEL and engineering and work-practice controls are not feasible or are not required.
(iii) Activities in regulated areas specified in paragraph (e) of this section.
(iv) Work operations for which the employer has implemented all feasible engineering and work-practice
controls and such controls are not sufficient to reduce employee exposures to or below the PEL.
(v) Work operations for which an employee is exposed to cadmium at or above the action level, and the
employee requests a respirator.
(vi) Work operations for which an employee is exposed to cadmium above the PEL and engineering controls
are not required by paragraph (f)(1)(ii) of this section.
(vii) Emergencies.
(2) Respirator program. (i) The employer must implement a respiratory protection program in accordance
with §1910.134(b) through (d) (except (d)(1)(iii)), and (f) through (m), which covers each employee required
by this section to use a respirator.
(ii) No employees must use a respirator if, based on their most recent medical examination, the examining
physician determines that they will be unable to continue to function normally while using a respirator. If the
physician determines that the employee must be limited in, or removed from, their current job because of
their inability to use a respirator, the limitation or removal must be in accordance with paragraphs (l) (11) and
(12) of this section.
(iii) If an employee has breathing difficulty during fit testing or respirator use, the employer must provide the
employee with a medical examination in accordance with paragraph (l)(6)(ii) of this section to determine if
the employee can use a respirator while performing the required duties.
(3) Respirator selection. (i) Employers must:
(A) Select, and provide to employees, the appropriate respirators specified in paragraph (d)(3)(i)(A) of 29
CFR 1910.134.

(C) Provide HEPA filters for powered and non-powered air-purifying respirators.
(ii) The employer must provide an employee with a powered air-purifying respirator instead of a negativepressure respirator when an employee who is entitled to a respirator chooses to use this type of respirator
and such a respirator provides adequate protection to the employee.
(h) Emergency situations. The employer shall develop and implement a written plan for dealing with
emergency situations involving substantial releases of airborne cadmium. The plan shall include provisions
for the use of appropriate respirators and personal protective equipment. In addition, employees not
essential to correcting the emergency situation shall be restricted from the area and normal operations
halted in that area until the emergency is abated.

(i) Protective work clothing and equipment —(1) Provision and use. If an employee is exposed to airborne
cadmium above the PEL or where skin or eye irritation is associated with cadmium exposure at any level,
the employer shall provide at no cost to the employee, and assure that the employee uses, appropriate
protective work clothing and equipment that prevents contamination of the employee and the employee's
garments. Protective work clothing and equipment includes, but is not limited to:
(i) Coveralls or similar full-body work clothing;

equipment required by paragraph (i)(1) of this section in a clean and dry condition as often as necessary to
maintain its effectiveness, but in any event at least weekly. The employer is responsible for cleaning and
laundering the protective clothing and equipment required by this paragraph to maintain its effectiveness
and is also responsible for disposing of such clothing and equipment.
(ii) The employer also is responsible for repairing or replacing required protective clothing and equipment as
needed to maintain its effectiveness. When rips or tears are detected while an employee is working they
shall be immediately mended, or the worksuit shall be immediately replaced.
(iii) The employer shall prohibit the removal of cadmium from protective clothing and equipment by blowing,
shaking, or any other means that disperses cadmium into the air.
(iv) The employer shall assure that any laundering of contaminated clothing or cleaning of contaminated
equipment in the workplace is done in a manner that prevents the release of airborne cadmium in excess of
the permissible exposure limit prescribed in paragraph (c) of this section.
(v) The employer shall inform any person who launders or cleans protective clothing or equipment
contaminated with cadmium of the potentially harmful effects of exposure to cadmium and that the clothing
and equipment should be laundered or cleaned in a manner to effectively prevent the release of airborne
cadmium in excess of the PEL.

The equipment shall be used and emptied in a manner that minimizes the reentry of cadmium into the
workplace.
(5) Shoveling, dry or wet sweeping, and brushing may be used only where vacuuming or other methods that
minimize the likelihood of cadmium becoming airborne have been tried and found not to be effective.
(6) Compressed air shall not be used to remove cadmium from any surface unless the compressed air is
used in conjunction with a ventilation system designed to capture the dust cloud created by the compressed
air.
(7) Waste, scrap, debris, bags, containers, personal protective equipment, and clothing contaminated with
cadmium and consigned for disposal shall be collected and disposed of in sealed impermeable bags or
other closed, impermeable containers. These bags and containers shall be labeled in accordance with
paragraph (m)(2) of this section.
(l) Medical surveillance —(1) General —(i) Scope. (A) Currently exposed—The employer shall institute a
medical surveillance program for all employees who are or may be exposed to cadmium at or above the
action level unless the employer demonstrates that the employee is not, and will not be, exposed at or
above the action level on 30 or more days per year (twelve consecutive months); and,
(B) Previously exposed—The employer shall also institute a medical surveillance program for all employees
who prior to the effective date of this section might previously have been exposed to cadmium at or above
the action level by the employer, unless the employer demonstrates that the employee did not prior to the
effective date of this section work for the employer in jobs with exposure to cadmium for an aggregated total
of more than 60 months.
(ii) To determine an employee's fitness for using a respirator, the employer shall provide the limited medical
examination specified in paragraph (l)(6) of this section.
(iii) The employer shall assure that all medical examinations and procedures required by this standard are
performed by or under the supervision of a licensed physician, who has read and is familiar with the health

effects section of appendix A to this section, the regulatory text of this section, the protocol for sample
handling and laboratory selection in appendix F to this section, and the questionnaire of appendix D to this
section. These examinations and procedures shall be provided without cost to the employee and at a time
and place that is reasonable and convenient to employees.
(iv) The employer shall assure that the collecting and handling of biological samples of cadmium in urine
(CdU), cadmium in blood (CdB), and beta-2 microglobulin in urine (β2-M) taken from employees under this
section is done in a manner that assures their reliability and that analysis of biological samples of cadmium
in urine (CdU), cadmium in blood (CdB), and beta-2 microglobulin in urine (β2-M) taken from employees
under this section is performed in laboratories with demonstrated proficiency for that particular analyte. (See
appendix F to this section.)
(2) Initial examination. (i) The employer shall provide an initial (preplacement) examination to all employees
covered by the medical surveillance program required in paragraph (l)(1)(i) of this section. The examination
shall be provided to those employees within 30 days after initial assignment to a job with exposure to
cadmium or no later than 90 days after the effective date of this section, whichever date is later.
(ii) The initial (preplacement) medical examination shall include:
(A) A detailed medical and work history, with emphasis on: Past, present, and anticipated future exposure to
cadmium; any history of renal, cardiovascular, respiratory, hematopoietic, reproductive, and/or musculoskeletal system dysfunction; current usage of medication with potential nephrotoxic side-effects; and
smoking history and current status; and
(B) Biological monitoring that includes the following tests:
( 1 ) Cadmium in urine (CdU), standardized to grams of creatinine (g/Cr);
( 2 ) Beta-2 microglobulin in urine (β2-M), standardized to grams of creatinine (g/Cr), with pH specified, as
described in appendix F to this section; and
( 3 ) Cadmium in blood (CdB), standardized to liters of whole blood (lwb).
(iii) Recent Examination: An initial examination is not required to be provided if adequate records show that
the employee has been examined in accordance with the requirements of paragraph (l)(2)(ii) of this section
within the past 12 months. In that case, such records shall be maintained as part of the employee's medical
record and the prior exam shall be treated as if it were an initial examination for the purposes of paragraphs
(l)(3) and (4) of this section.
(3) Actions triggered by initial biological monitoring: (i) If the results of the initial biological monitoring tests
show the employee's CdU level to be at or below 3 µg/g Cr, β2-M level to be at or below 300 µg/g Cr and
CdB level to be at or below 5 µg/lwb, then:
(A) For currently exposed employees, who are subject to medical surveillance under paragraph (l)(1)(i)(A) of
this section, the employer shall provide the minimum level of periodic medical surveillance in accordance
with the requirements in paragraph (l)(4)(i) of this section; and
(B) For previously exposed employees, who are subject to medical surveillance under paragraph (l)(1)(i)(B)
of this section, the employer shall provide biological monitoring for CdU, β2-M, and CdB one year after the
initial biological monitoring and then the employer shall comply with the requirements of paragraph (l)(4)(v)
of this section.
(ii) For all employees who are subject to medical surveillance under paragraph (l)(1)(i) of this section, if the
results of the initial biological monitoring tests show the level of CdU to exceed 3 µg/g Cr, the level of β2-M to
exceed 300 µg/g Cr, or the level of CdB to exceed 5 µg/lwb, the employer shall:

(A) Within two weeks after receipt of biological monitoring results, reassess the employee's occupational
exposure to cadmium as follows:
( 1 ) Reassess the employee's work practices and personal hygiene;
( 2 ) Reevaluate the employee's respirator use, if any, and the respirator program;
( 3 ) Review the hygiene facilities;
( 4 ) Reevaluate the maintenance and effectiveness of the relevant engineering controls;
( 5 ) Assess the employee's smoking history and status;
(B) Within 30 days after the exposure reassessment, specified in paragraph (l)(3)(ii)(A) of this section, take
reasonable steps to correct any deficiencies found in the reassessment that may be responsible for the
employee's excess exposure to cadmium; and,
(C) Within 90 days after receipt of biological monitoring results, provide a full medical examination to the
employee in accordance with the requirements of paragraph (l)(4)(ii) of this section. After completing the
medical examination, the examining physician shall determine in a written medical opinion whether to
medically remove the employee. If the physician determines that medical removal is not necessary, then
until the employee's CdU level falls to or below 3 µg/g Cr, β2-M level falls to or below 300 µg/g Cr and CdB
level falls to or below 5 µg/lwb, the employer shall:
( 1 ) Provide biological monitoring in accordance with paragraph (l)(2)(ii)(B) of this section on a semiannual
basis; and
( 2 ) Provide annual medical examinations in accordance with paragraph (l)(4)(ii) of this section.
(iii) For all employees who are subject to medical surveillance under paragraph (l)(1)(i) of this section, if the
results of the initial biological monitoring tests show the level of CdU to be in excess of 15 µg/g Cr, or the
level of CdB to be in excess of 15 µg/lwb, or the level of β2-M to be in excess of 1,500 µg/g Cr, the employer
shall comply with the requirements of paragraphs (l)(3)(ii)(A)–(B) of this section. Within 90 days after receipt
of biological monitoring results, the employer shall provide a full medical examination to the employee in
accordance with the requirements of paragraph (l)(4)(ii) of this section. After completing the medical
examination, the examining physician shall determine in a written medical opinion whether to medically
remove the employee. However, if the initial biological monitoring results and the biological monitoring
results obtained during the medical examination both show that: CdU exceeds 15 µg/g Cr; or CdB exceeds
15 µg/lwb; or β2-M exceeds 1500 µg/g Cr, and in addition CdU exceeds 3 µg/g Cr or CdB exceeds 5 µg/liter
of whole blood, then the physician shall medically remove the employee from exposure to cadmium at or
above the action level. If the second set of biological monitoring results obtained during the medical
examination does not show that a mandatory removal trigger level has been exceeded, then the employee is
not required to be removed by the mandatory provisions of this paragraph. If the employee is not required to
be removed by the mandatory provisions of this paragraph or by the physician's determination, then until the
employee's CdU level falls to or below 3 µg/g Cr, β2-M level falls to or below 300 µg/g Cr and CdB level falls
to or below 5 µg/lwb, the employer shall:
(A) Periodically reassess the employee's occupational exposure to cadmium;

basis; and
(C) Provide semiannual medical examinations in accordance with paragraph (l)(4)(ii) of this section.
(iv) For all employees to whom medical surveillance is provided, beginning on January 1, 1999, and in lieu of
paragraphs (l)(3)(i)–(iii) of this section:

(A) If the results of the initial biological monitoring tests show the employee's CdU level to be at or below 3
µg/g Cr, β2-M level to be at or below 300 µg/g Cr and CdB level to be at or below 5 µg/lwb, then for currently
exposed employees, the employer shall comply with the requirements of paragraph (l)(3)(i)(A) of this
section, and for previously exposed employees, the employer shall comply with the requirements of
paragraph (l)(3)(i)(B) of this section;
(B) If the results of the initial biological monitoring tests show the level of CdU to exceed 3 µg/g Cr, the level
of β2-M to exceed 300 µg/g Cr, or the level of CdB to exceed 5 µg/lwb, the employer shall comply with the
requirements of paragraphs (l)(3)(ii)(A)–(C) of this section; and,
(C) If the results of the initial biological monitoring tests show the level of CdU to be in excess of 7 µg/g Cr,
or the level of CdB to be in excess of 10 µg/lwb, or the level of β2-M to be in excess of 750 µg/g Cr, the
employer shall: Comply with the requirements of paragraphs (l)(3)(ii)(A)–(B) of this section; and, within 90
days after receipt of biological monitoring results, provide a full medical examination to the employee in
accordance with the requirements of paragraph (l)(4)(ii) of this section. After completing the medical
examination, the examining physician shall determine in a written medical opinion whether to medically
remove the employee. However, if the initial biological monitoring results and the biological monitoring
results obtained during the medical examination both show that: CdU exceeds 7 µg/g Cr; or CdB exceeds 10
µg/lwb; or β2-M exceeds 750 µg/g Cr, and in addition CdU exceeds 3 µg/g Cr or CdB exceeds 5 µg/liter of
whole blood, then the physician shall medically remove the employee from exposure to cadmium at or
above the action level. If the second set of biological monitoring results obtained during the medical
examination does not show that a mandatory removal trigger level has been exceeded, then the employee is
not required to be removed by the mandatory provisions of this paragraph. If the employee is not required to
be removed by the mandatory provisions of this paragraph or by the physician's determination, then until the
employee's CdU level falls to or below 3 µg/g Cr, β2-M level falls to or below 300 µg/g Cr and CdB level falls
to or below 5 µg/lwb, the employer shall: periodically reassess the employee's occupational exposure to
cadmium; provide biological monitoring in accordance with paragraph (l)(2)(ii)(B) of this section on a
quarterly basis; and provide semiannual medical examinations in accordance with paragraph (l)(4)(ii) of this
section.
(4) Periodic medical surveillance. (i) For each employee who is covered under paragraph (l)(1)(i)(A) of this
section, the employer shall provide at least the minimum level of periodic medical surveillance, which
consists of periodic medical examinations and periodic biological monitoring. A periodic medical examination
shall be provided within one year after the initial examination required by paragraph (l)(2) of this section and
thereafter at least biennially. Biological sampling shall be provided at least annually, either as part of a
periodic medical examination or separately as periodic biological monitoring.
(ii) The periodic medical examination shall include:
(A) A detailed medical and work history, or update thereof, with emphasis on: Past, present and anticipated
future exposure to cadmium; smoking history and current status; reproductive history; current use of

(iii) Periodic biological monitoring shall be provided in accordance with paragraph (l)(2)(ii)(B) of this section.
(iv) If the results of periodic biological monitoring or the results of biological monitoring performed as part of
the periodic medical examination show the level of the employee's CdU, β2-M, or CdB to be in excess of the
levels specified in paragraphs (l)(3)(ii) or (iii); or, beginning on January 1, 1999, in excess of the levels
specified in paragraphs (l)(3)(ii) or (iv) of this section, the employer shall take the appropriate actions
specified in paragraphs (l)(3)(ii)–(iv) of this section.
(v) For previously exposed employees under paragraph (l)(1)(i)(B) of this section:
(A) If the employee's levels of CdU did not exceed 3 µg/g Cr, CdB did not exceed 5 µg/lwb, and β2-M did not
exceed 300 µg/g Cr in the initial biological monitoring tests, and if the results of the followup biological
monitoring required by paragraph (l)(3)(i)(B) of this section one year after the initial examination confirm the
previous results, the employer may discontinue all periodic medical surveillance for that employee.
(B) If the initial biological monitoring results for CdU, CdB, or β2-M were in excess of the levels specified in
paragraph (l)(3)(i) of this section, but subsequent biological monitoring results required by paragraph
(l)(3)(ii)–(iv) of this section show that the employee's CdU levels no longer exceed 3 µg/g Cr, CdB levels no
longer exceed 5 µg/lwb, and β2-M levels no longer exceed 300 µg/g Cr, the employer shall provide biological
monitoring for CdU, CdB, and β2-M one year after these most recent biological monitoring results. If the
results of the followup biological monitoring, specified in this paragraph, confirm the previous results, the
employer may discontinue all periodic medical surveillance for that employee.
(C) However, if the results of the follow-up tests specified in paragraph (l)(4)(v)(A) or (B) of this section
indicate that the level of the employee's CdU, β2–M, or CdB exceeds these same levels, the employer is
required to provide annual medical examinations in accordance with the provisions of paragraph (l)(4)(ii) of
this section until the results of biological monitoring are consistently below these levels or the examining
physician determines in a written medical opinion that further medical surveillance is not required to protect
the employee's health.
(vi) A routine, biennial medical examination is not required to be provided in accordance with paragraphs
(l)(3)(i) and (l)(4) of this section if adequate medical records show that the employee has been examined in
accordance with the requirements of paragraph (l)(4)(ii) of this section within the past 12 months. In that
case, such records shall be maintained by the employer as part of the employee's medical record, and the
next routine, periodic medical examination shall be made available to the employee within two years of the
previous examination.
(5) Actions triggered by medical examinations. (i) If the results of a medical examination carried out in
accordance with this section indicate any laboratory or clinical finding consistent with cadmium toxicity that
does not require employer action under paragraph (l)(2), (3) or (4) of this section, the employer, within 30
days, shall reassess the employee's occupational exposure to cadmium and take the following corrective
action until the physician determines they are no longer necessary:
(A) Periodically reassess: The employee's work practices and personal hygiene; the employee's respirator
use, if any; the employee's smoking history and status; the respiratory protection program; the hygiene
facilities; and the maintenance and effectiveness of the relevant engineering controls;
(B) Within 30 days after the reassessment, take all reasonable steps to correct the deficiencies found in the
reassessment that may be responsible for the employee's excess exposure to cadmium;

(C) Provide semiannual medical reexaminations to evaluate the abnormal clinical sign(s) of cadmium toxicity
until the results are normal or the employee is medically removed; and
(D) Where the results of tests for total proteins in urine are abnormal, provide a more detailed medical
evaluation of the toxic effects of cadmium on the employee's renal system.
(6) Examination for respirator use. (i) To determine an employee's fitness for respirator use, the employer
shall provide a medical examination that includes the elements specified in paragraph (l)(6)(i)(A)–(D) of this
section. This examination shall be provided prior to the employee's being assigned to a job that requires the
use of a respirator or no later than 90 days after this section goes into effect, whichever date is later, to any
employee without a medical examination within the preceding 12 months that satisfies the requirements of
this paragraph.
(A) A detailed medical and work history, or update thereof, with emphasis on: Past exposure to cadmium;
smoking history and current status; any history of renal, cardiovascular, respiratory, hematopoietic, and/or
musculoskeletal system dysfunction; a description of the job for which the respirator is required; and
questions 3–11 and 25–32 in appendix D to this section;
(B) A blood pressure test;
(C) Biological monitoring of the employee's levels of CdU, CdB and β2-M in accordance with the
requirements of paragraph (l)(2)(ii)(B) of this section, unless such results already have been obtained within
the previous 12 months; and
(D) Any other test or procedure that the examining physician deems appropriate.
(ii) After reviewing all the information obtained from the medical examination required in paragraph (l)(6)(i) of
this section, the physician shall determine whether the employee is fit to wear a respirator.
(iii) Whenever an employee has exhibited difficulty in breathing during a respirator fit test or during use of a
respirator, the employer, as soon as possible, shall provide the employee with a periodic medical
examination in accordance with paragraph (l)(4)(ii) of this section to determine the employee's fitness to
wear a respirator.
(iv) Where the results of the examination required under paragraph (l)(6)(i), (ii), or (iii) of this section are
abnormal, medical limitation or prohibition of respirator use shall be considered. If the employee is allowed
to wear a respirator, the employee's ability to continue to do so shall be periodically evaluated by a
physician.
(7) Emergency examinations. (i) In addition to the medical surveillance required in paragraphs (l)(2)–(6) of
this section, the employer shall provide a medical examination as soon as possible to any employee who
may have been acutely exposed to cadmium because of an emergency.
(ii) The examination shall include the requirements of paragraph (l)(4)(ii) of this section, with emphasis on
the respiratory system, other organ systems considered appropriate by the examining physician, and
symptoms of acute overexposure, as identified in paragraphs II (B)(1)–(2) and IV of appendix A to this
section.
(8) Termination of employment examination. (i) At termination of employment, the employer shall provide a
medical examination in accordance with paragraph (l)(4)(ii) of this section, including a chest X-ray, to any
employee to whom at any prior time the employer was required to provide medical surveillance under
paragraphs (l)(1)(i) or (l)(7) of this section. However, if the last examination satisfied the requirements of
paragraph (l)(4)(ii) of this section and was less than six months prior to the date of termination, no further
examination is required unless otherwise specified in paragraphs (l)(3) or (l)(5) of this section;
(ii) However, for employees covered by paragraph (l)(1)(i)(B) of this section, if the employer has
discontinued all periodic medical surveillance under paragraph (l)(4)(v) of this section, no termination of
employment medical examination is required.

from the examining physician for each medical examination performed on each employee. This written
opinion shall contain:
(A) The physician's diagnosis for the employee;
(B) The physician's opinion as to whether the employee has any detected medical condition(s) that would
place the employee at increased risk of material impairment to health from further exposure to cadmium,
including any indications of potential cadmium toxicity;
(C) The results of any biological or other testing or related evaluations that directly assess the employee's
absorption of cadmium;
(D) Any recommended removal from, or limitation on the activities or duties of the employee or on the
employee's use of personal protective equipment, such as respirators;
(E) A statement that the physician has clearly and carefully explained to the employee the results of the
medical examination, including all biological monitoring results and any medical conditions related to
cadmium exposure that require further evaluation or treatment, and any limitation on the employee's diet or
use of medications.
(ii) The employer promptly shall obtain a copy of the results of any biological monitoring provided by an
employer to an employee independently of a medical examination under paragraphs (l)(2) and (l)(4) of this
section, and, in lieu of a written medical opinion, an explanation sheet explaining those results.
(iii) The employer shall instruct the physician not to reveal orally or in the written medical opinion given to the
employer specific findings or diagnoses unrelated to occupational exposure to cadmium.
(11) Medical Removal Protection (MRP) —(i) General. (A) The employer shall temporarily remove an
employee from work where there is excess exposure to cadmium on each occasion that medical removal is
required under paragraph (l)(3), (l)(4), or (l)(6) of this section and on each occasion that a physician
determines in a written medical opinion that the employee should be removed from such exposure. The
physician's determination may be based on biological monitoring results, inability to wear a respirator,
evidence of illness, other signs or symptoms of cadmium-related dysfunction or disease, or any other reason
deemed medically sufficient by the physician.
(B) The employer shall medically remove an employee in accordance with paragraph (l)(11) of this section
regardless of whether at the time of removal a job is available into which the removed employee may be
transferred.

(C) Whenever an employee is medically removed under paragraph (l)(11) of this section, the employer shall
transfer the removed employee to a job where the exposure to cadmium is within the permissible levels
specified in that paragraph as soon as one becomes available.
(D) For any employee who is medically removed under the provisions of paragraph (l)(11)(i) of this section,
the employer shall provide follow-up biological monitoring in accordance with (l)(2)(ii)(B) of this section at
least every three months and follow-up medical examinations semi-annually at least every six months until in
a written medical opinion the examining physician determines that either the employee may be returned to
his/her former job status as specified under paragraph (l)(11)(iv)–(v) of this section or the employee must be
permanently removed from excess cadmium exposure.
(E) The employer may not return an employee who has been medically removed for any reason to his/her
former job status until a physician determines in a written medical opinion that continued medical removal is
no longer necessary to protect the employee's health.
(ii) Where an employee is found unfit to wear a respirator under paragraph (l)(6)(ii) of this section, the
employer shall remove the employee from work where exposure to cadmium is above the PEL.
(iii) Where removal is based on any reason other than the employee's inability to wear a respirator, the
employer shall remove the employee from work where exposure to cadmium is at or above the action level.
(iv) Except as specified in paragraph (l)(11)(v) of this section, no employee who was removed because
his/her level of CdU, CdB and/or β2-M exceeded the medical removal trigger levels in paragraph (l)(3) or
(l)(4) of this section may be returned to work with exposure to cadmium at or above the action level until the
employee's levels of CdU fall to or below 3 µg/g Cr, CdB falls to or below 5 µg/lwb, and β2-M falls to or below
300 µg/g Cr.
(v) However, when in the examining physician's opinion continued exposure to cadmium will not pose an
increased risk to the employee's health and there are special circumstances that make continued medical
removal an inappropriate remedy, the physician shall fully discuss these matters with the employee, and
then in a written determination may return a worker to his/her former job status despite what would
otherwise be unacceptably high biological monitoring results. Thereafter, the returned employee shall
continue to be provided with medical surveillance as if he/she were still on medical removal until the
employee's levels of CdU fall to or below 3 µg/g Cr, CdB falls to or below 5 µg/lwb, and β2-M falls to or below
300 µg/g Cr.
(vi) Where an employer, although not required by paragraph (l)(11)(i)–(iii) of this section to do so, removes
an employee from exposure to cadmium or otherwise places limitations on an employee due to the effects of
cadmium exposure on the employee's medical condition, the employer shall provide the same medical
removal protection benefits to that employee under paragraph (l)(12) of this section as would have been
provided had the removal been required under paragraph (l)(11)(i)–(iii) of this section.
(12) Medical Removal Protection Benefits (MRPB). (i) The employer shall provide MRPB for up to a
maximum of 18 months to an employee each time and while the employee is temporarily medically removed
under paragraph (l)(11) of this section.
(ii) For purposes of this section, the requirement that the employer provide MRPB means that the employer
shall maintain the total normal earnings, seniority, and all other employee rights and benefits of the removed
employee, including the employee's right to his/her former job status, as if the employee had not been
removed from the employee's job or otherwise medically limited.
(iii) Where, after 18 months on medical removal because of elevated biological monitoring results, the
employee's monitoring results have not declined to a low enough level to permit the employee to be returned
to his/her former job status:
(A) The employer shall make available to the employee a medical examination pursuant to this section in
order to obtain a final medical determination as to whether the employee may be returned to his/her former
job status or must be permanently removed from excess cadmium exposure; and

(B) The employer shall assure that the final medical determination indicates whether the employee may be
returned to his/her former job status and what steps, if any, should be taken to protect the employee's
health.
(iv) The employer may condition the provision of MRPB upon the employee's participation in medical
surveillance provided in accordance with this section.
(13) Multiple physician review. (i) If the employer selects the initial physician to conduct any medical
examination or consultation provided to an employee under this section, the employee may designate a
second physician to:
(A) Review any findings, determinations, or recommendations of the initial physician; and
(B) Conduct such examinations, consultations, and laboratory tests as the second physician deems
necessary to facilitate this review.
(ii) The employer shall promptly notify an employee of the right to seek a second medical opinion after each
occasion that an initial physician provided by the employer conducts a medical examination or consultation
pursuant to this section. The employer may condition its participation in, and payment for, multiple physician
review upon the employee doing the following within fifteen (15) days after receipt of this notice, or receipt of
the initial physician's written opinion, whichever is later:
(A) Informing the employer that he or she intends to seek a medical opinion; and
(B) Initiating steps to make an appointment with a second physician.
(iii) If the findings, determinations, or recommendations of the second physician differ from those of the initial
physician, then the employer and the employee shall assure that efforts are made for the two physicians to
resolve any disagreement.
(iv) If the two physicians have been unable to quickly resolve their disagreement, then the employer and the
employee, through their respective physicians, shall designate a third physician to:
(A) Review any findings, determinations, or recommendations of the other two physicians; and
(B) Conduct such examinations, consultations, laboratory tests, and discussions with the other two
physicians as the third physician deems necessary to resolve the disagreement among them.
(v) The employer shall act consistently with the findings, determinations, and recommendations of the third
physician, unless the employer and the employee reach an agreement that is consistent with the
recommendations of at least one of the other two physicians.
(14) Alternate physician determination. The employer and an employee or designated employee
representative may agree upon the use of any alternate form of physician determination in lieu of the
multiple physician review provided by paragraph (l)(13) of this section, so long as the alternative is
expeditious and at least as protective of the employee.
(15) Information the employer must provide the employee. (i) The employer shall provide a copy of the
physician's written medical opinion to the examined employee within two weeks after receipt thereof.
(ii) The employer shall provide the employee with a copy of the employee's biological monitoring results and
