Drycleaning Solvent (P-D-680) is TOXIC and flammable. Wear protective goggles, face

shield, and gloves; use only 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 II Drycleaning Solvent is 140 degrees F (60 degrees

C) and Type III Drycleaning Solvent is 200 degrees F (93 degrees 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.

Brake shoes may be covered with dust. Breathing this dust may be harmful to your health.

Do not use compressed air to clean brake shoes. Wear a filter mask approved for use against

brake dust. Failure to comply may result in injury or death to personnel.
