Dry cleaning solvent P-D-680 (safety or Stoddard's Solvent) is potentially dangerous. Avoid repeated and
prolonged breathing of vapors and skin contact with the liquid. Do not use near open flame, arcing
equipment, or other ignition sources. Always wear eye protection and protective clothing. The flash point
of P-D-680 is 100° to 138°F (38° to 59°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 kgcm2) or less. When
working with compressed air always use chip guards, eye protection, and other personal protective
equipment.
