General Maintenance Procedures.
Drycleaning solvent is TOXIC and flammable. Wear protective goggles 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 drycleaning solvent; the flashpoint for Type II is 140
degrees F (60 degrees C), and for Type III it is 200 degrees F (93 degrees C).
Failure to follow this warning may result in death or injury to personnel.
If personnel become dizzy while using drycleaning solvent, immediately get
fresh air and medical help. If solvent contacts skin or clothes, flush with cold
water. If solvent contacts eyes, immediately flush them with water and get
immediate medical attention.
When drycleaning solvent is used, notify the local medical authority (preventive
medicine) and environmental coordinator concerning medical surveillance,
respiratory protection, and disposal requirements.
Do not use drycleaning solvent on winch rope (cable). Solvent will soak into
rope strands and rust, causing rope to deteriorate. This may result in the rope
breaking under normal loads and could cause death or injury to personnel.
