WARNING
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 standards.
·
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.
