b. Cracks or Breaks.
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.
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 used, a suitable fire
extinguisher kept nearby, and requirements of TC 9-237 strictly followed.
IHMEE must be properly prepared before welding, or damage to equipment may result.
Repair minor skin cracks or breaks by installing patches.
c. Follow-On Maintenance.
Remove "Do Not Operate" tag from ignition switch (TM 5-2420-230-10).
