CLEANING/INSPECTION:
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 (380 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.
