WARNING
Dry cleaning solvent is flammable and potentially
dangerous to people and property. Do not use near
open flame, sparks, 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 used to blow dirt
from skin or clothing. Air entering body openings is
extremely dangerous. Compressed air used for
cleaning shall not exceed 100 psi (690 kPa). Use
