micro-organisms that may be present in human blood
and can cause disease in humans. Infections such as
Hepatitis B, Hepatitis C and human immuodeficiency virus
(HIV, the virus that causes AIDS) are some examples
of BBP.
b. COMPOSITE AND ADVANCED COMPOSITE. A
composite “system of materials”, made up of two unlike
materials, acting as a homogenous solid in its finished
form. Two common materials used in aerospace design
are a man-made fiber embedded within a matrix. The
matrix is a polymeric material or resin consisting of longchained
organic molecules. The fiber provides the
strength and the matrix provides toughness and durability
while protecting the fibers. Glass fiber dispersed within
an epoxy matrix is an example of a conventional composite.
Advanced composites use fibers that possess
greater strengths than fibers used within a conventional
composite system. Examples of an advanced composite
are carbon, boron or Kevlar®(aramid) dispersed within
an epoxy resin.
c. DISASTER CONTROL GROUP (DCG). The response
element that deploys to the scene of a major accident
to command, control and recover (not aircraft recovery)
the site in preparation for the arrival of the investigation
board. The DCG is comprised of two subgroups,
the initial re-sponse group and the follow-on element.
d. FIRST RESPONSE. The firefighting response is
sometimes called the first response because they reach
the mishap scene first. The fire chief will serve as the
on-scene-commander until the site is declared safe and
casualties are under medical care.
e. FOLLOW-ON RESPONSE. This disaster control
subgroup responds to a pre-planned assembly point and
deploys when the on-scene-commander (fire chief) determines
a safe route to enter the scene. The element
may include readiness, bioenvironmental engineering,
civil engineering, EOD, aircraft maintenance, ground/flight
safety, mortuary affairs, transportation, public affairs, accident
investigators and others deemed necessary.
f. HAZARDOUS AEROSPACE MATERIALS. Materials
and systems integrated into aerospace vehicles that
can present a potential safety and health hazard to personnel
responding to mishaps. This includes composites,
radar absorbing material (RAM), radioactive material
and protective coatings.
g. INITIAL RESPONSE ELEMENT. This disaster control
subgroup responds immediately to on or near-base
mishap scenes. The element consists of medical, security,
fire protection and possibly munitions or ordinance.
h. RADAR ABSORBING MATERIAL (RAM). There
are a number of design parameters used to achieve a
low observable (LO) or “stealth” characteristic. One is to
use a coating material that is radar absorbing. One type
of RAM coating is a polymeric based material loaded with
a metal or ceramic particles/powder. The older RAM
coatings used ferrite as the particle.
i. SECONDARY RESPONSE. When the investigation
process releases the site, activity occurs to recover the
aircraft and to return the property/real estate to its normal
state. The secondary response are the elements
that prepare the pieces for shipment, off site aircraft storage,
environmental assessment and finally disposal.
Even though the emergency response has ceased, potential
hazards can still exist for the secondary response
elements.

3.3 KNOWN SOLID, LIQUID AND GAS HAZARDS.
This paragraph contains information on known hazardous
chemicals and flammable liquids associated with aircraft
or aerospace vehicles. A list of vehicles and locations
of materials is provided where possible. A summary
of hazards for specific vehicles are found in Table
3.3-1.
a. ANHYDROUS AMMONIA. Anhydrous ammonia is
99.5% (by weight) basic ammonia (NH ) and is normally
a pungent, color-less vapor.
(1) HEALTH HAZARD. A hazardous toxic fluid. Liquid
form produces severe burns on contact. Gaseous
form is a strong irritant and can damage the eyes and
the entire respiratory tract.
(2) FIRST AID. Remove victim from contaminated atmosphere.
If skin is contacted, flush the area of contact
with large amounts of water, and seek the care of a physician.
(3) RESPIRATORY PROTECTION. Entry into an ammonia
atmosphere is extremely hazardous. Approved
respiratory protection equipment shall be worn at all times
in this atmosphere.
(4) AIRCRAFT AND LOCATION. Orbiter Vehicle has
two tanks in the aft fuselage.
b. ANTI-ICING FLUID. Anti-icing fluids are usually a
mixture of about 85% alcohol and 15% glycerin. While
not as great as other aircraft hazards, it should be remembered
