(10) Do not attempt to handle cylindrical objects, ejection
seats, and anything that does not hamper firefighting
action.
(11) Radioactive materials are used in small quantities.
Radiation is invisible and some types of rays easily penetrate
firefighter’s protective clothing. Breathing apparatus
may protect against one kind but not another. Protection
is managed by limiting time around the source
and creating distance from the source.
(a) Radiation is measured by a survey meter or a Geiger
counter. The dosage absorbed can be measured by
a dosimeter. The Bioenvirnonmental Engineer will be
equipped to detect and measure radiation.

(12) Attempt to control runoff without endangering personnel
and equipment.
(13) Overhaul is to be performed to determine if deepseated
smoldering is occurring. A systematic approach
is taken so the wreckage isn’t disturbed beyond that which
is necessary to conduct firefighting and rescue operations.
Check for hotspots using infrared detection.
(14) Due to the possibility of deep-seated smoldering
of plastics and composite materials, postfire does not
begin until composite material is at ambient temperature.
(15) A combination of health and safety concerns can
exist. The preliminary site evaluation will identify suspected
conditions that are immediately dangerous to life
or health or may cause serious harm. A summary of specific
hazards is found in Table 3.5-6. Approximate locations
should be noted. The immediate concerns include
the following:
(a) smoldering
(b) explosives
(c) electrical
(d) radiological
(e) toxic
(16) Once the immediate threats are controlled the following
is noted.
(a) Area affected by bloodborne pathogen contamination.
(b) Amount of environmental exposure from fire fighting
agents.
(c) Type and amount of site damage.
(d) Local equipment damage.
(e) Exposed personnel.
(f) Type and amount of composite debris. Common
terms are used to describe the debris:
1 fragments
2 delaminated layers
3 strips
4 clusters
5 fiber bundles
6 dust
7 charred
8 surface scorched
9 coatings
10 sandwich laminate
(17) Take note of conditions that are likely to produce
airborne carbon fiber:
(a) dry or arid climate
(b) large amount of unidirectional tape carbon fiber
laminate that experienced physical and fire damage.
(c) pool fire
(d) high prevailing winds
(e) carbon fiber clusters strewn around the burnt debris
and outside of the burn area
(f) single fibers can collect on plastics around the area.
(g) airborne fibers collected on plastic face piece
(h) By reflection, fibers can be seen floating in the air
surrounding the burnt debris directly following flaming
combustion.
(18) Adequate protection from airborne particulate and
smoke is needed if EOD needs to enter an area of the
site where there is a high potential of smoldering composites.
(19) Recovery operations will not begin until all
firefighting and rescue efforts are complete.
(20) Fixant can be applied once all site imminent hazards
have been taken care of and the composite temperature
is at ambient. Approval may be needed from
the SIB before application begins.
(21) Composite spray team may need to be escorted if
area is not clear of explosives hazards.
(22) A gross washdown pool can be used to avoid secondary
exposure from soot and composite dust from
firefighting gear but to minimize contaminated waste at
the site a simple wipe down of the gear can serve to
eliminate surface dust.
(a) Gently wipe the aluminized proximity suit, helmet,
and boots, with soap and water or hand wipes for
plume exposure.
TO 00-105E-9
(23) Decontamination for bloodborne pathogen will follow
NFPA Standard 1500 protocol.
(24) Firefighting equipment should be decontaminated
at the site by water washing (preferred) or vacuum.
(25) Soot and carbon fiber is electrostatic. If the aircraft
was exposed to the plume, the following should be taken:
(a) Vacuum the air intakes.
(b) For internally ingested smoke, visually inspect all
components for debris and vacuum thoroughly.
(c) Prior to flying perform electrical checks and engine
run-up.
(d) For significantly affected equipment thoroughly
clean antenna insulators, exposed transfer bushings, circuit
breakers, etc. Inspect air intakes and outlets for signs
of smoke or debris and decontaminate as necessary.
(26) Include all safety and health information in writing
at the transfer of command (see Checklist 3.10-2).
