Equipment Hazards.

TM 43-0139 WARNING Apply only heat-resisting paints (para 2-34) to items attaining temperatures of more than 400°F (204°C), such as manifolds, exhaust pipes, and mufflers. Other paints, at these temperatures, may produce toxic vapors and/or equipment damage. CAUTION Coatings should not be applied at temperatures below 50°F (10^OC). h. Equipment Hazards. WARNING Only electrical equipment/wiring conforming to NFPA Article 70 will be used where spray-painting is being done. WARNING All electrical equipment must be properly grounded before starting any painting procedures. CAUTION Mask intake and exhaust parts, breathers, etc., carefully to prevent dust, solution, water, or metal conditioner from entering the engines of vehicles. CAUTION Do not use solvents or paints with solvents on electronic equipment as this may cause changes in performance. Refer to Appendix C for painting of electronic equipment. CAUTION Do not use petroleum base products on natural rubber as they are destructive agents. CAUTION Do not paint/overspray CARC or other solvent-containing paints on vinyl, rubber or lacquer-coated items, as these items are not solvent resistant. CAUTION Do not apply CARC to flexible items. Due to its rigidity, the CARC finish may crack when item is bent. CAUTION Do not use spray equipment containing any aluminum components to apply coatings formulated with chlorinated solvents (such as MIL-C-46168, Type III). 1-8
