BAP GENERAL WELDING MAINTENANCE (continued).
WARNING
Unusable CARC mixtures are considered hazardous waste and will require disposal
in accordance with Federal, state, Department of Defense, Department of the Army,
and local installation hazardous waste regulations. Consult the installation
environmental office for proper disposal guidance. Mixed CARC is extremely
flammable. Use only in a well-ventilated areas. Keep away from open flames, sparks,
and other ignition sources.
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 use CARC paint without adequate ventilation.
NEVER weld or cut CARC-coated materials.
DO NOT grind or sand paint 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.
CAUTION
Do not weld the BAP while on truck or trailer or while loaded with bridge bay or
damage to equipment may result.
d. BAP Welding. Welding on the BAP must be performed when the BAP has been removed from the CBT or
PLS trailer and the bridge bay load has been removed. Different areas of the BAP require different weld
electrodes. Use the guidelines given in Table 5-2 to determine the correct weld.
