or upon contamination.
(h) Protective clothing must be placed in closeable,
leak-proof container built to contain all contents during
handling, storing, transporting or shipping and be appropriately
labeled or color-coded.
(6) HANDLING CONTAMINATED COMPOSITES. If
it is evident or suspected the debris is contaminated, protection
is mandatory.
Handle is such a way as to not cross contaminate other
surfaces. Minimize splattering and generation of droplets.
Place contaminated pieces in an impervious plastic
bag before placing in the appropriate transportation or
shipping container. Double bagging is required if there
are exposed fibers that could puncture the bag. These
bags can also be referred to as barrier paper.
NOTE
Regulated waste found at a mishap site would be contaminated
aircraft debris that would release blood or infectious
materials in a liquid or semi-liquid state if compressed;
items that are caked with dried blood or other
potentially infectious materials are capable of releasing
these materials during handling and the personal protective
clothing.
(7) LABELING PROCEDURE. Contaminated pieces
will be bagged or wrapped in plastic and labeled as biological
waste before the pieces are removed from the
mishap site. Red bags or a red container may be substituted
for a label. Labels shall state which portions are
contaminated. Containers used to store, transport or ship
infectious materials will have warning labels affixed to
the container. If the storage or shipping container is labeled
then the individual waste containers that are placed
in the storage container does not have to be labeled.
(8) DECONTAMINATION OF EQUIPMENT OR WORK
SURFACES. A solution of 5.25% sodium hypochlorite
(household bleach) diluted between 1:10 to 1:100 with
water is acceptable for cleaning. If decontamination of
equipment is not done at the work site, the equipment is
properly labeled before leaving the work site.
NOTE
Do not decontaminate laboratory samples. Make sure
the laboratory sample has been properly identified for
BBP.
c. CONFINED SPACES. Limited openings, restricted
work areas and unfavorable natural ventilation can be
caused by terrain, environmental conditions and crash
conditions.
(1) HEALTH HAZARDS. Trapped air and an increase
of toxic air contaminants.
(2) FIRST AID. Provide fresh air.
(3) PRECAUTIONS. Monitor the space for hazards
conditions. Light the area as much as possible. Use appropriate
PPE—such as an air purify respirator if airborne
particulate is present or is going to be generated.
NOTE
Respirator cartridge life will decrease for labor intensive
work (increases the breathing rate) and for increased localized
airborne particulate concentrations.

d. COMPOSITE MATERIALS. To make a rapid assessment,
the information is provided in a similar format found
in Emergency Response Guidebook (ERG). Always use
the current version to avoid misinformation.
(1) HAZARDS. Mishap scenarios present different
types of damage. Typical damages are structural or explosion
with or without a fire or just fire damage. Two fire
situationsoccur that present different exposure concerns.
Situation one is the early stage of a fuel-fed fire. With or
without composite material a burning aircraft generates
a large amount of soot, lethal and toxic gases. The addition
of composite materials adds to the amount of lethal
and toxic gases. Composite materials do contribute to
the soot content of the plume but most of the soot will be
due to the JP8 fuel during a flaming combustion condition.
Situation two is when the fire is largely out and only
a small amount of fume and smoke is being generated
and large amount of debris is present. Rapid generation
of lethal gases will drop rapidly with the decrease in flame
temperature. Deep-seated composite smoldering may
be occurring without producing visable smoke, light or
intense heat. Smoldering smoke is toxic.
(a) HEALTH. Health concerns associated with
burning plastics apply to burning composite material.
Avoid skin contact with dust/particulate. Avoid inhaling
airborne fibrous particulate. Effects of smoldering inhalation
may be delayed. Fire produces irritating, corrosive,
and /or toxic gases. Structural and explosion damaged
composites will cause puncture wounds and the particulate
will cause skin irritations.
(b) FIRE. Using NFPA 704 M placard system,
the following placard describes a generic composite part
for a fire-fighting response. Health describes the combustion
