WARNING
Drycleaning solvent, P-D-680, used to clean
parts is potentially dangerous to personnel
and property. Avoid repeated and prolonged
skin contact by wearing rubber or non-porous
gloves when handling the solvent or material
wet with drycleaning solvent. Wash hands
immediately after exposure with soap and
water and use a lanolin based skin cream to
prevent skin drying. Do not use near open
flame or excessive heat. Flash point of solvent
is 1 000F (380C). Do not work with solvent
in a closed room. Be sure there is good
ventilation or the solvent vapors will build up
in the air and become a poisonous mixture
which can cause physical injury or even death.
