Chromium (VI)
A
1910.1026(a)
Scope.
1910.1026(a)(1)
This standard applies to occupational exposures to chromium (VI) in all forms and
compounds in general industry, except:
1910.1026(a)(2)
Exposures that occur in the application of pesticides regulated by the Environmental
Protection Agency or another Federal government agency (e.g., the treatment of wood with
preservatives);
1910.1026(a)(3)
Exposures to portland cement; or
1910.1026(a)(4)
Where the employer has objective data demonstrating that a material containing chromium
or a specific process, operation, or activity involving chromium cannot release dusts, fumes,
or mists of chromium (VI) in concentrations at or above 0.5 µg/m3 as an 8-hour timeweighted average (TWA) under any expected conditions of use.
1910.1026(b)
Definitions. For the purposes of this section the following definitions apply:
Action level means a concentration of airborne chromium (VI) of 2.5 micrograms per cubic
meter of air (2.5 µg/m3) 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.
Chromium (VI) [hexavalent chromium or Cr(VI)] means chromium with a valence of
positive six, in any form and in any compound.
Director means the Director of the National Institute for Occupational Safety and Health
(NIOSH), U.S. Department of Health and Human Services, or designee.
Emergency means any occurrence that results, or is likely to result, in an uncontrolled
release of chromium (VI). If an incidental release of chromium (VI) can be controlled at the
time of release by employees in the immediate release area, or by maintenance personnel, it
is not an emergency.
Employee exposure means the exposure to airborne chromium (VI) that would occur if the
employee were not using a respirator.
High-efficiency particulate air [HEPA] filter means a filter that is at least 99.97 percent
efficient in removing mono-dispersed particles of 0.3 micrometers in diameter or larger.
Historical monitoring data means data from chromium (VI) monitoring conducted prior to
May 30, 2006, obtained during work operations conducted under workplace conditions closely
resembling the processes, types of material, control methods, work practices, and
environmental conditions in the employer's current operations.
Objective data means information such as air monitoring data from industry-wide surveys
or calculations based on the composition or chemical and physical properties of a substance
demonstrating the employee exposure to chromium (VI) associated with a particular product
or material or a specific process, operation, or activity. The data must reflect workplace
conditions closely resembling the processes, types of material, control methods, work
practices, and environmental conditions in the employer's current operations.
Physician or other licensed health care professional [PLHCP] is an individual whose
legally permitted scope of practice (i.e., license, registration, or certification) allows him or
her to independently provide or be delegated the responsibility to provide some or all of the
particular health care services required by paragraph (k) of this section.
Regulated area means an area, demarcated by the employer, where an employee's
exposure to airborne concentrations of chromium (VI) exceeds, or can reasonably be
expected to exceed, the PEL.
This section means this § 1910.1026 chromium (VI) standard.
1910.1026(c)
Permissible exposure limit (PEL). The employer shall ensure that no employee is exposed
to an airborne concentration of chromium (VI) in excess of 5 micrograms per cubic meter of
air (5 µg/m3), calculated as an 8-hour time-weighted average (TWA).
1910.1026(d)
Exposure determination.
1910.1026(d)(1)
General. Each employer who has a workplace or work operation covered by this section shall
determine the 8-hour TWA exposure for each employee exposed to chromium (VI). This
determination shall be made in accordance with either paragraph (d)(2) or paragraph (d)(3)
of this section.
1910.1026(d)(2)
Scheduled monitoring option.
1910.1026(d)(2)(i)
The employer shall perform initial monitoring to determine the 8-hour TWA exposure for each
employee on the basis of a sufficient number of personal breathing zone air samples to
accurately characterize full shift exposure on each shift, for each job classification, in each
work area. Where an employer does representative sampling instead of sampling all
employees in order to meet this requirement, the employer shall sample the employee(s)
expected to have the highest chromium (VI) exposures.
1910.1026(d)(2)(ii)
If initial monitoring indicates that employee exposures are below the action level, the
employer may discontinue monitoring for those employees whose exposures are represented
by such monitoring.
1910.1026(d)(2)(iii)
If monitoring reveals employee exposures to be at or above the action level, the employer
shall perform periodic monitoring at least every six months.
1910.1026(d)(2)(iv)
If monitoring reveals employee exposures to be above the PEL, the employer shall perform
periodic monitoring at least every three months.
1910.1026(d)(2)(v)
If periodic monitoring indicates that employee exposures are below the action level, and the
result is confirmed by the result 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.
1910.1026(d)(2)(vi)
The employer shall perform additional monitoring when there has been any change in the
production process, raw materials, equipment, personnel, work practices, or control methods
that may result in new or additional exposures to chromium (VI), or when the employer has
any reason to believe that new or additional exposures have occurred.
1910.1026(d)(3)
Performance-oriented option. The employer shall determine the 8-hour TWA exposure for
each employee on the basis of any combination of air monitoring data, historical monitoring
data, or objective data sufficient to accurately characterize employee exposure to chromium
(VI).
1910.1026(d)(4)
Employee notification of determination results.
1910.1026(d)(4)(i)
Where the exposure determination indicates that employee exposure exceeds the PEL, within
15 working days the employer shall either post the results in an appropriate location that is
accessible to all affected employees or shall notify each affected employee individually in
writing of the results.
1910.1026(d)(4)(ii)
Whenever the exposure determination indicates that employee exposure is above the PEL,
the employer shall describe in the written notification the corrective action being taken to
reduce employee exposure to or below the PEL.
1910.1026(d)(5)
Accuracy of measurement. Where air monitoring is performed to comply with the
requirements of this section, the employer shall use a method of monitoring and analysis
that can measure chromium (VI) to within an accuracy of plus or minus 25 percent (+/25%) and can produce accurate measurements to within a statistical confidence level of 95
percent for airborne concentrations at or above the action level.
1910.1026(d)(6)
Observation of monitoring.
1910.1026(d)(6)(i)
Where air monitoring is performed to comply with the requirements of this section, the
employer shall provide affected employees or their designated representatives an opportunity
to observe any monitoring of employee exposure to chromium (VI).
1910.1026(d)(6)(ii)
When observation of monitoring requires entry into an area where the use of protective
clothing or equipment is required, the employer shall provide the observer with clothing and
equipment and shall assure that the observer uses such clothing and equipment and
complies with all other applicable safety and health procedures.
1910.1026(e)
Regulated areas.
1910.1026(e)(1)
Establishment. The employer shall establish a regulated area wherever an employee's
exposure to airborne concentrations of chromium (VI) is, or can reasonably be expected to
be, in excess of the PEL.
1910.1026(e)(2)
Demarcation. The employer shall ensure that regulated areas are demarcated from the rest
of the workplace in a manner that adequately establishes and alerts employees of the
boundaries of the regulated area.

employer shall use engineering and work practice controls to reduce and maintain employee
exposure to chromium (VI) to or below the PEL unless the employer can demonstrate that
such controls are not feasible. Wherever feasible engineering and work practice controls are
not sufficient to reduce employee exposure to or below the PEL, the employer shall use them
to reduce employee exposure to the lowest levels achievable, and shall supplement them by
the use of respiratory protection that complies with the requirements of paragraph (g) of this
section.
1910.1026(f)(1)(ii)
Where painting of aircraft or large aircraft parts is performed in the aerospace industry, the
employer shall use engineering and work practice controls to reduce and maintain employee
exposure to chromium (VI) to or below 25 µg/m3 unless the employer can demonstrate that
such controls are not feasible. The employer shall supplement such engineering and work
practice controls with the use of respiratory protection that complies with the requirements of
paragraph (g) of this section to achieve the PEL.
1910.1026(f)(1)(iii)
Where the employer can demonstrate that a process or task does not result in any employee
exposure to chromium (VI) above the PEL for 30 or more days per year (12 consecutive
months), the requirement to implement engineering and work practice controls to achieve
the PEL does not apply to that process or task.
