excessive heat, or on hot surfaces. Flash point of P-D-680
solvent is 100° to 138°F (38 to 59 C). Use solvent in a
well-ventilated area, and avoid inhaling fumes. If repeatedly
exposed to fumes, seek fresh air and immediate medical
help. Avoid prolonged exposure of skin to solvent. Wash
exposed skin immediately and thoroughly.
Death or severe injury might result when compressed air is
