Unsafe welding practices can cause serious injury from fire, explosions, or harmful
agents. Allow only authorized personnel to weld or cut metals, and follow safety precau-
tions in TC 9-237. Protective clothing and goggles must be worn, adequate protective
equipment must be used, a suitable fire extinguisher must be kept nearby, and require-
ments of TC 9-237 must be strictly followed. Failure to comply may result in serious
injury or death to personnel.
CARC paint contains isocyanate (HDI), which is highly irritating to skin and respira-
tory system. High concentrations of HDI can produce symptoms of itching and redden-
ing of skin, a burning sensation in throat and nose, and watering of the eyes. In
extreme concentrations, HDI can cause cough, shortness of breath, pain during respira-
tion, increased sputum production, and chest tightness. The following precautions must
be taken whenever using CARC paint:
ALWAYS use air line respirators when using CARC paint, unless air sampling shows
exposure to be below standards. Use chemical cartridge respirator if air sampling is
DO NOT let skin or eyes come in contact with CARC paint. Always wear protective
equipment (gloves, ventilation mask, safety goggles, etc.).
DO NOT use CARC paint without adequate ventilation.
NEVER weld or cut CARC-coated materials.
DO NOT grind or sand painted equipment without high-efficiency air purifying
respirators in use.
BE AWARE of CARC paint exposure symptoms; symptoms can occur a few days after
initial exposure. Seek medical help immediately if symptoms are detected.
