WARNING
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.
