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:

NEVER weld or cut CARC-coated materials.

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; adjustable protective equipment

used and suitable fire extinguisher kit near by; and requirements of TC 9-237 strictly followed

or serious injury or death to personnel could result.
