operations. The removal of munitions may not always be
possible due to the condition of the aircraft. A case-bycase
evaluation is made.
(g) Verify components of canopy jettison and seat ejection
system has been safed or disarmed prior to performing
recovery operations.
(h) Verify all electrical systems are de-energized.
(i) Disconnect battery prior to recovery operations. Remove
the battery from the aircraft if there was any spillage
or damage.
(j) Obtain weather information prior to lifting. Conditions
may interfere with cranes, tow vehicles, or helicopter use
and crash trailer placement at the site.
(k) Use absorbent pads as soon as possible to soak up
spilled fuels when performing the recovery operation.
Avoid any operation that can cause a spark or ignite the
spill.
(l) Identify downwind direction especially when working
around spills and burnt composite debris.
(m) Contain damaged composites with fixant and canvas
before aircraft recovery operations begin following
instructions found in paragraph 3.8.e.
(n) Before removing aircraft wreckage perform a dry
run with the equipment and technique.
(o) Team chief monitor operations and evaluate the effectiveness
of the plan.
(p) Aerial recovery of aircraft will disperse loose dust or
debris. A soil tackifier spray will help keep the dust from
becoming airborne.
(3) Mishap debris containment.
(a) Debris that will be scrapped requires a sorting process
and proper composite containment before transport-
ing off-site. Systematically separate and box the debris.
Composite material is separated from non-composite
and containerized. Containers needed:
1 Large bulk pieces: wood box with a cover (cardboard
will not provide containment throughout the lifecycle
of the wreckage).
2 Small size pieces: five or ten-gallon plastic buckets
with lids.
3 Labeled tags:

Content
Fixant Type
Spray Purpose
WARNING
Flammable solid. Use Class B fire extinguishant. Dust
is an eye, skin and inhalation irritant. Fibers cause puncture
wounds. Burnt debris has an unpleasant odor.
(b) Indoor storage. Burnt and/or damaged bulk composite
pieces are sprayed with fixant and wrapped before
containerizing.
1 Follow fixant spraying procedure in 3.8.d. and see
Table 3.8-6 for Fiber Hold-Down Solution(s) Rationale.
2 Wrap with plastic and/or canvas and tape.
(c) Outdoor storage. Plastic wrap and tape is not suitable
for outdoor storage. PAA fixant is not a permanent
hold-down solution. Sharp edges tear the plastic exposing
the debris and the tape degrades. Canvas wrapped
plastic can provide additional protection but may not be
waterproof. The following is required if the composite
debris cannot be containerized.
1 Contain fibers with a permanent fixant solution. Corrosion
preventative compound (CPC), MIL-C-16173
Grade 4 spray has been tested for environmental exposure.
2 If CPC is not available then use PAA fixant.
3 Wrap and tape with 0.006-inch plastic and canvas
or with rubber coated canvas.
4 Tag and label, see 3.a.3 above.

(4) Site Cleanup.
(a) Work practice:
1 Do not dry sweep. It puts dust in the air.
2 Use water or a vacuum system with a HEPA filter for
cleaning surfaces and equipment.
3 Compressed air is not for cleaning clothes or equipment.
4 Work upwind of dust clouds or dusty areas when
possible.
5 Report any skin and breathing irritations, cuts or
rashes.
NOTE
When in a protective suit under high heat conditions, heat
stress or prickly heat can be misconstrued to be a rash
developed from composite exposure.
6 No smoking, drinking or eating.
7 Shower as soon as possible after working with severely
damaged composites, contact with burnt debris
and liquid spills.
8 Use hand signals for line-of-sight communication.
(b) Composite handling at the site is a localized concern.
Exposure issues are right at the damaged pieces.
Identify work area when clearing site of composite debris
piles. A work zone of not more than 25 feet is appropriate
for handling quantities of damaged composites.
CAUTION
CONTAINS
COMPOSITE DUST AND FIBERS
Avoid creating dust
Do not enter work area without proper protection
(c) Moving composite debris around with a backhoe or
forklift will generate loose composite dust and fibers. Avoid
flying fragments and spread of debris when moving piles
of debris. Spray fixant solution on bulk composite debris
before movement begins.
(d) Direct contact when moving piles of loose composite
