WARNING TM 9-2350-311-34-1 5-2 FUEL TANKS — CONTINUED b. Repair ● ● ● ● ● Do not smoke or use open flames when removing tanks. Wear respirator and rubberized protective clothing when working on fiberglass. Fiberglass inhalation can cause severe respiratory problems. Fiberglass particles embedded in skin will cause irritation and possible infection. Immediately after working with fiberglass and resin, thoroughly wash any exposed skin surfaces. If fiber particles are imbedded in skin, do not scrub. Rinse area in warm, soapy water and seek medical assistance. NOTE Upper and lower fuel tanks are repaired using same procedures. Applying fiberglass and epoxy repair materials in cold shop retards curing. Steps 1 thru 20 apply to tanks with repair holes larger than 1 in. (2.54 cm). Steps 21 thru 27 apply to tanks with cracks or punctures smaller than 1 in. (25.4 mm). 1 For holes larger than 1 in. (2.54 cm) across at any point, cut away damaged area. Make a smooth-edged circular opening. Sharp angular cuts make repair more difficult. 2 Scarf crater with at least 1.5 in. (3.81 cm) sloping sides, down to opening. Dry-cleaning solvent (P-D-880) is toxic and flammable. Wear protective goggles and gloves and use only in a well-ventilated area. Avoid contact with skin, eyes, and clothes. Do not breath vapors. Do not use near open flame or excessive heat. The flashpoint for type #1 is 100°F (38°C), and for type #2 is 138°F (59°C). If you become dizzy while using dry-cleaning solvent, get fresh air immediately and obtain medical aid. If contact with eyes is made, wash your eyes with water and obtain medical aid immediately. 3 Remove dust and clean repair area with dry-cleaning solvent. NOTE Presence of oil in repair area will result in poor adhesion. 4 Use 0.125 in. (3.2 mm) application of regenerated silica compacted under warm pad to withdraw oil for improved adhesion. 5 Measure repair area and estimate material requirement. 5-14
