equipment or other ignition sources. Always wear eye protection and protective clothing. The flash point of
P-D-680 is 100 to 138 deg. F (30 to 59 deg. C).
Death or serious injury could occur if compressed air is directed against the skin. Do not use compressed
air for cleaning or drying unless the pressure Is/has been reduced to 30 psi (2.11 kg/cm2) or less. When
