CHEMICAL AND BIOLOGICAL HAZARD SAFETY
Figure 1-11
Chemicals and Diesel Engine Exhaust
Sewer Gas Hazard
• Do not smoke or have lighted materials in or around
sewer lines, drains, or catch basins.
Chemical Waste Hazard
• Storm drains, catch basins, and sewers may contain
harmful chemicals. To prevent contamination and
injury, wear chemical resistant gloves, long sleeves,
trousers, and safety glasses or face shields.
• Seek immediate medical attention if exposure or
contamination is suspected.
Biological Hazards
• Germs and other biological hazards are common in
sewers, drains, and catch basins. Use appropriate
personal protective equipment to avoid injury and
contamination. Get medical attention for injuries
associated with cleaning sewers, drains, and catch
basins if biological contamination is suspected.
Dust Hazard
• Repeated or substantial breathing of hazardous
dusts, including crystalline silica, could cause fatal or
serious respiratory disease including silicosis.
Concrete, masonry, many types of rock, and various
other materials contain silica sand. California lists
repairable crystalline silica as a substance known to
cause cancer. Operation of this equipment under
certain conditions may generate airborne dust
particles that could contain crystalline silica. In those
conditions personal protective equipment including
an appropriate respirator must be used. If excessive
dust is generated, a dust collection or suppression
system should also be used during operation.
California Proposition 65: Diesel engine exhaust
and some of its constituents are known to the
state of California to cause cancer, birth defects,
and other reproductive harm.
Battery posts, terminals, and related accessories
contain lead and lead compounds, chemicals
known to the state of California to cause cancer
and birth defects or other reproductive harm.
Wash hands after handling.
Always read carefully and comply fully with the
manufacturer’s instructions when handling fuels,
oils, solvents, cleansers, and any other chemical
agent.
