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 below
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
BE AWARE of CARC paint exposure symptoms; symptoms can occur a few days after
initial exposure. Seek medical help immediately if symptoms are detected.
Grind off paint in area marked in Step (6) for sensor plate (9) to be mounted.
