6-6. INTRODUCTION (CONT).
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.
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.
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
j. Welding Procedures. Welding may be used to repair cracks in steel parts. These repairs should be made only
when replacement parts are not available. Do not weld running parts. Visually inspect all welds for cracks. Parts that
carry a great load should receive magnetic particle inspection. Critical nonferrous parts may be inspected with
k. Sheet Metal Repair. Straighten minor body dents by bumping with a soft-faced hammer while using a wooden
block backing. Repair minor skin cracks by installing patches.
