with the liquid. Do not use near open flame, arcing equipment, or other ignition
source. 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.
