sprayed. Maintain a distance of at least 25 feet
from the air compressor. If possible, locate
the air compressor in a separate room.
6. Read all of the information concerning
coating products and cleaning solvents.
Do not use chlorinated solvents
(e.g. 1-1-1 trichloroethylene and
dichloromethane, also known as
methylene chloride) to clean spray guns.
Many spray guns contain aluminum,
which reacts strongly to chlorinated solvents.
Contact the solvent or coating manufacturer as
needed regarding potential chemical reactions.
7. Spraying hazardous materials may result in serious
injury or death. Do not spray pesticide, acid,
corrosive material, fertilizer, or toxic chemicals.
8. Paints and solvents may be harmful or fatal if
swallowed or inhaled. Avoid prolonged skin
