WARNING
Take the following precautions before grinding, cutting, or welding any equipment that has
been CARC-coated:
Wear protective equipment (e.g., goggles, gloves, apron) when grinding or
sanding CARC-coated equipment. Do not leave any skin exposed.
Use high-efficiency air purifying respirators when grinding or sanding CARC-coated
equipment.
Never weld or cut CARC-coated equipment; grind or sand off CARC paint
completely before welding.
CARC paint contains isocyanate (HDI) which is highly irritating to the skin and
respiratory system. High concentrations of HDI can produce itching and reddening
of the skin, a burning sensation in the throat and nose, and watering of the eyes.
In extreme concentrations, HDI can cause coughing, shortness of breath, pain
during respiration, increased sputum production, and chest tightness.
Failure to follow these warnings may result in injury or death to personnel.
CAUTION
Remove CARC paint from fittings prior to removal. Failure to follow this caution will cause
damage to equipment.
