WARNING
Dry-cleaning solvent (PD-680) is toxic and flammable. Wear protective goggles and gloves; use
in a well ventilated area; avoid contact with skin, eyes, and clothes, and do not breathe vapors.
Keep away from heat or flame. Never smoke when using solvent; the flashpoint for type I dry-
cleaning solvent is 100 degrees Fahrenheit (oF) (37.8 degrees Celsius [oC]) and for type II is 138oF
(58.9oC). Failure to do so may result in injury or death to personnel.
If personnel become dizzy while using dry-cleaning solvent, immediately get fresh air and
medical help. If drycleaning solvent contacts skin or clothes flush with cold water. If solvent
contacts eyes, immediately flush eyes with water and get immediate medical help.
Use dry-cleaning solvent (Appx. C, item 16) on all metal surfaces. Use detergent (Appx. C, item 11) and
water when you clean rubber or plastic materials.
