APPENDIX A TO SUBPART B OF PART
1915—COMPLIANCE
ASSISTANCE
GUIDELINES FOR CONFINED AND ENCLOSED SPACES AND OTHER DANGEROUS ATMOSPHERES
This appendix is a non-mandatory set of
guidelines provided to assist employers in
complying with the requirements of this subpart. This appendix neither creates additional obligations nor detracts from obligations otherwise contained in the standard. It
is intended to provide explanatory information and educational material to employers
and employees to foster understanding of,
and compliance with, the standard.
Sections 1915.11 through 1915.16. These standards are minimum safety standards for entering and working safely in vessel tanks
and compartments.
Section 1915.11(b) Definition of ‘‘Hot work.’’
There are several instances in which circumstances do not necessitate that grinding,
drilling, abrasive blasting be regarded as hot
work. Some examples are:
1. Abrasive blasting of the hull for paint
preparation does not necessitate pumping
and cleaning the tanks of a vessel.
2. Prior to hot work on any hollow structure, the void space should be tested and appropriate precautions taken.
Section 1915.11(b) Definition of ‘‘Lower explosive limit.’’ The terms lower flammable
limit (LFL) and lower explosive limit (LEL)
are used interchangeably in fire science literature.
Section 1915.11(b) Definition of ‘‘Upper explosive limit.’’ The terms upper flammable
limit (UFL) and upper explosive limit (UEL)
are used interchangeably in fire science literature.
Section 1915.12(a)(3). After a tank has been
properly washed and ventilated, the tank
should contain 20.8 percent oxygen by volume. This is the same amount found in our
normal atmosphere at sea level. However, it
is possible that the oxygen content will be
lower. When this is the case, the reasons for
this deficiency should be determined and
corrective action taken.
An oxygen content of 19.5 percent can support life and is adequate for entry. However,
any oxygen level greater than 20.8 percent by
volume should alert the competent person to
look for the cause of the oxygen-enriched atmosphere and correct it prior to entry. In addition, any oxygen level lower than 19.5 percent level should also alert the competent
person to look for the cause of the oxygendeficiency and correct it prior to entry.
Section 1915.12(b)(3) Flammable atmospheres.
Atmospheres with a concentration of flammable vapors at or above 10 percent of the

posted at an individual tank, compartment or work space within a work area
if the entire work area has been tested
and certified: not safe for workers, not

29 CFR Ch. XVII (7–1–07 Edition)

lower explosive limit (LEL) are considered
hazardous when located in confined spaces.
However, atmospheres with flammable vapors below 10 percent of the LEL are not necessarily safe.
Such atmospheres are too lean to burn.
Nevertheless, when a space contains or produces measurable flammable vapors below
the 10 percent LEL, it might indicate that
flammable vapors are being released or introduced into the space and could present a
hazard in time. Therefore, the cause of the
vapors should be investigated and, if possible, eliminated prior to entry.
Some situations that have produced measurable concentrations of flammable vapors
that could exceed 10 percent of the LEL in
time are:
1. Pipelines that should have been blanked
or disconnected have opened, allowing product into the space.
2. The vessel may have shifted, allowing
product not previously cleaned and removed
during washing to move into other areas of
the vessel.
3. Residues may be producing the atmosphere by releasing flammable vapor.
Section 1915.12(b)(6) Flammable atmospheres
that are toxic. An atmosphere with a measurable concentration of a flammable substance
below 10 percent of the LEL may be above
the OSHA permissible exposure limit for
that substance. In that case, refer to
§ 1915.12(c) (2), (3), and (4).
Sections
1915.13(b)(4),
1915.15(c),
and
1915.15(e). The frequency with which a tank
is monitored to determine if atmospheric
conditions are being maintained is a function of several factors that are discussed
below:
1. Temperature. Higher temperatures will
cause a combustible or flammable liquid to
vaporize at a faster rate than lower temperatures. This is important since hotter days
may cause tank residues to produce more vapors and that may result in the vapors exceeding 10 percent of the LEL or an overexposure to toxic contaminants.
2. Work in the tank. Any activity in the
tank could change the atmospheric conditions in that tank. Oxygen from a leaking
oxyfuel hose or torch could result in an oxygen-enriched atmosphere that would more
easily propagate a flame. Some welding operations use inert gas, and leaks can result in
an oxygen-deficient atmosphere. Manual
tank cleaning with high pressure spray devices can stir up residues and result in exposures to toxic contaminants. Simple cleaning or mucking out, where employees walk
through and shovel residues and sludge, can
create a change in atmospheric conditions.
3. Period of time elapsed. If a period of time
has elapsed since a Marine Chemist or Coast
Guard authorized person has certified a tank
as safe, the atmospheric condition should be

rechecked by the competent person prior to
entry and starting work.
4. Unattended tanks or spaces. When a tank
or space has been tested and declared safe,
then subsequently left unattended for a period of time, it should be retested prior to
entry and starting work. For example, when
barges are left unattended at night, unidentified products from another barge are sometimes dumped into their empty tanks. Since
this would result in a changed atmosphere,
the tanks should be retested prior to entry
and starting work.
5. Work break. When workers take a break
or leave at the end of the shift, equipment
sometimes is inadvertently left in the tanks.
At lunch or work breaks and at the end of
the shift are the times when it is most likely
someone will leave a burning or cutting
torch in the tank, perhaps turned on and
leaking oxygen or an inert gas. Since the
former can produce an oxygen-enriched atmosphere, and the latter an oxygen-deficient
atmosphere, tanks should be checked for
equipment left behind, and atmosphere,
monitored if necessary prior to re-entering
and resuming work. In an oxygen-enriched
atmosphere, the flammable range is severely
broadened. This means that an oxygen-enriched atmosphere can promote very rapid
burning.
6. Ballasting or trimming. Changing the position of the ballast, or trimming or in any
way moving the vessel so as to expose cargo
that had been previously trapped, can
produce a change in the atmosphere of the
tank. The atmosphere should be retested
after any such move and prior to entry or
work.
Section 1915.14 (a) and (b) Hot work. This is
a reminder that other sections of the OSHA
shipyard safety and health standards in part
1915 should be reviewed prior to starting any
hot work. Most notably, subpart D, Welding,
Cutting and Heating, places additional restrictions on hot work. The requirements of
§§ 1915.51 and 1915.53 must be met before hot
work is begun on any metal that is toxic or
is covered by a preservative coating respectively; the requirements of § 1915.54 must be
met before welding, cutting, or heating is
begun on any hollow containers or structures not covered by § 1915.12.
Section 1915.12(a)(2). During hot work, more
than 20.8 percent oxygen by volume can be
unsafe since it extends the normal flammable range. The standard permits the oxygen level to reach 22 percent by volume in
order to account for instrument error. However, the cause of excess oxygen should be investigated and the source removed.
Section 1915.16(b). If the entire vessel has
been found to be in the same condition, then
employers shall be considered to be in compliance with this requirement when signs
using appropriate warning language in accordance with § 1915.16(a) are posted at the

29 CFR Ch. XVII (7–1–07 Edition)

3. Title 46 CFR 91.50–1(c)(1) covering hot
work on cargo and miscellaneous vessels as
follows:
(a) The provisions of ‘‘Standard for the
Control of Gas Hazards on Vessels to be Repaired,’’ NFPA No. 306, published by National Fire Protection Association, 1
Batterymarch Park, Quincy, MA 02269, shall
be used as a guide in conducting the inspections and issuance of certificates required by
this section.
(b) Until an inspection has been made to
determine that such operation can be undertaken with safety, no alterations, repairs, or
other such operations involving riveting,
welding, burning, or like fire-producing actions shall be made:
(1) Within or on the boundaries of cargo
tanks which have been used to carry flammable or combustible liquid or chemicals in
bulk, or within spaces adjacent to such cargo
tanks; or,
(2) Within or on the boundaries of fuel
tanks; or,
(3) To pipe lines, heating coils, pumps, fittings, or other appurtenances connected to
such cargo or fuel tanks.
(c) Such inspections shall be made and evidenced as follows:
(1) In ports or places in the United States
or its territories and possessions the inspection shall be made by a Marine Chemist certificated by the National Fire Protection Association; however, if the services of such
certified Marine Chemist are not reasonably
available, the Officer in Charge, Marine Inspection, upon the recommendation of the
vessel owner and his contractor or their representative, shall select a person who, in the
case of an individual vessel, shall be authorized to make such inspection. If the inspection indicated that such operations can be
undertaken with safety, a certificate setting
forth the fact in writing and qualified as
may be required, shall be issued by the certified Marine Chemist or the authorized person before the work is started. Such qualifications shall include any requirements as
may be deemed necessary to maintain, insofar as can reasonably be done, the safe conditions in the spaces certified throughout the
operation and shall include such additional
tests and certifications as considered required. Such qualifications and requirements
shall include precautions necessary to eliminate or minimize hazards that may be
present from protective coatings or residues
from cargoes.

work period.
(3) Employees shall be protected
against toxic vapors by suitable respiratory protective equipment in accordance with the requirements of subpart I of this part and, where necessary, against exposure of skin and
eye contact with toxic solvents and
their vapors by suitable clothing and
equipment.
