debris requires full respiratory, eye and skin protection.
(e) If the conditions at the site are going to re-suspend
airborne particulates during cleanup, a tackifer spray can
be used to adhere loose particulates to the soil.
(f) Collect the debris and containerize in an organized
fashion. The debris can be sorted by system and material
type.
(g) Cleanup randomly scattered composite small fragments,
strips, clusters, core material, and foam by placing
into plastic labeled buckets.
(h) Large bulk pieces are placed into wood boxes.
(i) Bloodborne contaminated pieces will be boxed separately
and properly labeled, see paragraph 3.8.b.
(j) Remove loose contaminate such as composite dust
composite from hard surfaces like concrete by vacuuming
or a water/detergent wash.
(k) Soot removal from solid surfaces will require washing
with a high alkaline cleaner.
(l) Aircraft fuel and liquids, fire suppressant, and hydrazine
contamination will cause an environmental site assessment.
The final cleanup process will be determined
by the environmental assessment.
(n) Equipment decontamination method will depend on
type of contaminate:
1 loose contaminates like dust or particulate: HEPA
vacuum or water/detergent wash.
2 aircraft liquids:chemical rinses or high pressure
rinses with or without heat.
3 adhering contaminates like resin char or tacky plastic
materials: scrapping and brushing with a chemical
rinse.
4 electrostatic attached particles: spray or clean
eqipment before use with antistatic solutions.
(o) Wastewater should be collected and disposed of
properly. A number of methods have been used for collection:
trench, pool or tarp. The means of disposal will
be determined by the water contaminate and concentration.
(5) Transportation. All debris will be adequately contained
as described before transporting off site.
(a) Buckets are sealed with a lid.
(b) Debris is in a wood box covered with a lid or contained
within canvas.
(c) All containers are labeled.

(6) Personal protective equipment considerations are
based on the operation, site conditions and debris (type,
condition and amount). Use protection in accordance
with level of exposure encountered. A large number of
disposable gloves and disposable coveralls will be
needed. See Table 3.8-4 for PPE Considerations.

OPERATION PROTECTION CONSIDERATION EQUIPMENT
Clean up of randomly scattered
small size composite debris:
fragments, strips, clusters,
pieces of sandwich structures,
foam.
Picking up small pieces scattered
over a large area does not
generate an appreciable amount
of airborne particulate.
NOTE
Other operations, occurring at the
same time, site conditions and weather
may require additional protection.
OPERATION PROTECTION CONSIDERATION EQUIPMENT
Backhoe, forklift or shoveling of
damaged/burnt composite
debris.
Handling piles of damaged
composites can produce
appreciable amounts of airborne
particulate. WITH OR WITHOUT
FIXANT.
Requirement is for direct contact
with the debris.
Requirement is for anyone within
the workzone when piles of
composite debris are being
moved.
