vice some aircraft, e.g., E-3A. The mixture consists<br />
of 62 percent uninhibited ethylene glycol and<br />
38 percent reagent water (EGW).<br />
(2) Environmental fluid servicing vehicle/cart positioning<br />
for aircraft servicing will be accomplished<br />
in accordance with procedures for positioning fuel<br />
vehicles. The fluid servicing vehicle/cart will be<br />
bonded to the aircraft before hoses are connected<br />
to aircraft.<br />
<strong>Air</strong>craft alcohol vapors are toxic and adequate<br />
ventilation must be provided in areas where alcohol<br />
is handled. Never work in a confined area or<br />
space without mechanical ventilation or respiratory<br />
protection. Most alcohols are flammable liquids.<br />
c. Water-alcohol mixtures are used for thrust augmentation<br />
in turbojet engines and for Anti-Detonation Injection<br />
(ADI) or internal coolant in reciprocating engines.<br />
Quality control requirements are covered in <strong>TO</strong> 42C-<br />
1-16. Water-alcohol servicing vehicle positioning for<br />
aircraft servicing will be in accordance with procedures<br />
in <strong>TO</strong> 36A12-13-1-131CL-1.<br />
4.29 AIRCRAFT DE-ICING.<br />
De-icing fluid can be applied to an aircraft with any or all of<br />
its engines operating as long as the following apply:<br />
a. Personnel and equipment must remain outside the individual<br />
aircraft engine danger areas.<br />
b. Avoid spraying any de-icing fluid into any engine intakes,<br />
aircraft ventilation, Environmental Control System<br />
(ECS) air inlets or Jet Fuel Starters (JFS) inlet and<br />
exhaust areas.<br />
c. Do not apply de-icing fluid during any fuel servicing<br />
operations.<br />
d. Do not apply de-icing fluid when any LOX equipment<br />
is within <strong>25</strong> feet. (De-icing fluids can be applied to<br />
aircraft having installed LOX converters as long as the<br />
access doors are closed.)<br />
4.30 AIRCRAFT TIRE SERVICING.<br />
The following general guidance applies to all aircraft installed<br />
tire inflation operations in excess of 50 psi.<br />
a. Servicer shall comply with specific operating instructions<br />
and safety precautions prescribed for aircraft being<br />
serviced and inflating tools and servicing units being<br />
used.<br />
b. Impact resistant safety goggles or impact resistant<br />
safety glasses with sideshields shall be worn by the<br />
tire servicer.<br />
c. The nitrogen or compressed air source used for servicing<br />
shall have a serviceable regulator for controlling<br />
service line pressure.<br />
d. Servicing with compressed nitrogen shall be done only<br />
with Class I (water pumped) nitrogen.<br />
e. An approved, calibrated tire inflating tool with relief<br />
valve and minimum ten foot servicing hose shall be<br />
used during tire inflation.<br />
f. Servicer shall be positioned in front or aft of tire being<br />
serviced during inflation, at full length of inflating<br />
tool’s hose. Hose shall not be tightly stretched. The<br />
immediate area to either side of tire being inflated shall<br />
be clear of personnel. (See Figure 4-2.)<br />
