•
Dry-cleaning solvent (P-D-680) is TOXIC and flammable. Wear protective goggles and gloves;

I dry-cleaning solvent is 100°F (38°C) and for type II is 138°F (50°C). Failure to do so may result
in injury or death to personnel.
•
If personnel become dizzy while using cleaning solvent, immediately get fresh air and medical
help. If solvent contacts skin or clothes, flush with cold water. If solvent contacts eyes,
immediately flush eyes with water and get immediate medical attention.

Compressed air used for cleaning purposes will not exceed 30 psi (207 kPa). Use only with
effective chip guarding and personal protective equipment (goggles/shield, gloves, etc.).
