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
precautions 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 requirements 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
respiratory system. High concentrations of HDI can produce symptoms of itching and
reddening 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
respiration, 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.
