Install or remove electrical cables through or
near asbestos-containing materials.
Personal Protective Clothing
Personnel who handle asbestos-containing
materials where the concentration of airborne fibers is
likely to exceed the PEL should wear protective
clothing. Be sure all openings are closed and that the
garment fits snugly around your neck wrist, and ankles.
Tape the junctions at the wrist, ankles, and collar as
necessary to prevent skin contamination. The following
paragraphs list recommended items and precautions:
Wear a full-body, one-piece, disposable coverall
preferably made of Tyvek or a comparable
substitute. Use a Tyvek coverall with attached
hood if possible.
Hoods should extend beyond the collar of the
overall and completely protect the neck. The
hood should be made of Tyvek or a comparable
Wear medium-weight rubber gloves and a thin
cotton under glove to absorb perspiration.
Wear slip-resistant plastic shoe covers or heavy
polyethylene shoe covers with slip-resistant
soles or lightweight rubber boots.
Wear face shields, vented goggles, or other
appropriate eye protection equipment whenever
there is a possibility of eye irritation.
When you are doing asbestos work and the
concentration of airborne fibers is unknown, wear a
full-facepiece, continuous-flow coupled air respirator.
The Ambient Air Breathing Apparatus meets this
requirement. Personnel who are not working on
asbestos but are in the space for other reasons should
wear at least a half-mask air purifying respirator
equipped with a high-efficiency filter.
Warning Signs and Labels
The command should display warning signs at each
location where concentrations of airborne asbestos
fibers may exceed the PEL. Post the signs at a distance
from the area to warn anyone who may be approaching.
The signs may include a list of the protective equipment
required for the area. The sign should contain at least
the following information:
DANGER, ASBESTOS. CANCER AND
LUNG DISEASE HAZARD. AUTHORIZED
PERSONNEL ONLY. RESPIRATORS AND
P R O T E C T I V E C L O T H I N G A RE
REQUIRED IN THIS AREA.
There may be conditions where containers of raw
materials, mixtures, scrap, waste, debris, and other
products containing asbestos could increase the
surrounding levels of airborne asbestos fibers. If so,
place warning labels on the containers in letters that are
visible and legible. The labels should contain at least the
DANGER, CONTAINS ASBESTOS
FIBERS. AVOID CREATING DUST.

Workplace Release Criteria
There are a few simple but necessary guidelines you
should follow before you reoccupy a space where
asbestos work has been done. Conduct a critical visual
inspection after clean-up to be sure the area is clean and
free of visible asbestos dust. The safety officer must
conduct the inspection after emergency or operational
readiness repairs at sea. Do not release an asbestos
controlled area for unrestricted access nor for air
sampling until the area has first been thoroughly cleaned
and inspected. Use local exhaust ventilation if necessary
to be sure the atmospheric levels of asbestos do not
There are a few simple but important guidelines you
should follow to dispose of asbestos waste. Be sure the
waste is wet if conditions justify. Double-bag the waste
in heavy-duty plastic bags or other suitable
impermeable containers that are color-coded for easy
recognition. Be sure all bags or containers have standard
asbestos warning labels. Be careful that bags and other
containers do not rupture when they are transported to
a shore activity for disposal.
For guidance concerning specific health-related
precautions to be used for specific operations, consult
the cognizant industrial hygienist.
