DRAFT
This list summarizes critical warnings in this technical bulletin. They are repeated here to let you know how
important they are. Study these warnings carefully. They can save your life and the lives of personnel you work
with. If there is any doubt about handling tools, materials, equipment, and procedures, see TB 43-0216, Safety and
Hazard Warnings for Operation and Maintenance of TACOM Equipment.
FOR INFORMATION ON FIRST AID, REFER TO FM 4-25.11.
WARNING
Adhesives, solvents, and sealing compounds can burn easily, can give off harmful
vapors and are harmful to skin and clothing.
To avoid injury or death, keep away
from open fire and use in well-ventilated areas.
If adhesive, solvent, or sealing
compound gets on skin or clothing, wash immediately with soap and water.
WARNING
Ensure engine is cool prior to checking AC compressor belts.
Failure to comply may
result in injury to personnel.
WARNING
Dry cleaning solvent is TOXIC and flammable.
Wear protective goggles and gloves;
use only in a well-ventilated area; avoid contact with skin, eyes, and clothes; and DO
NOT breathe vapors.
Keep away from heat or flame.
Never smoke when using dry
cleaning solvent; the flashpoint for Type II is 140°F (60°C), and for Type III it is 200°F
(93°C).
Failure to follow this warning may result in death or injury to personnel.
WARNING
If personnel become dizzy while using dry cleaning solvent, immediately get fresh
air and medical help.
If solvent contacts skin or clothes, flush with cold water.
If
solvent contacts eyes, immediately flush eyes with water and get immediate medical
attention.
WARNING
Use care to prevent refrigerant from touching skin or eyes.
Liquid refrigerant, when
exposed to air, quickly evaporates and will freeze skin or eye tissues.
Use care to
prevent refrigerant from touching your skin or eyes.
Serious injury or blindness may
result if you come in contact with liquid refrigerant.
WARNING
Refrigerant R-134a air conditioning systems should not be pressure tested or leak
tested with compressed air.
Combustible mixtures of air and R-134a may form,
resulting in fire or explosion, which could cause personnel injury or death.
WARNING
Ensure engine is cool before performing maintenance.
Failure to comply may result
in severe burns.
WARNING
Do not work in an area where refrigerant may contact an open flame or any burning
material, such as a cigarette.
When it contacts extreme heat, refrigerant breaks
down into poisonous phosgene gas.
Which if breathed, causes severe respiratory
irritation.
Do not breathe fumes from an open flame leak detector.
