HAZARDOUS FLUIDS
Improper handling of hazardous fluids or inhaling toxic vapors can cause extremely serious injury or death
from splashing in the eyes, ingestion, or bodily contamination. Observe all the following precautions when
you handle hazardous or potentially hazardous fluids.
D Know what fluid you are pumping and its specific hazards. Take precautions to avoid a toxic fluid spill.
D Always wear appropriate clothing and equipment, such as eye protection and breathing apparatus, to
protect yourself.
D Store hazardous fluid in an appropriate, approved container. Dispose of it according to all Local, State,
and Federal guidelines for hazardous fluids.
D Secure the fluid outlet hose tightly into the receiving container to prevent it from coming loose and
improperly draining the fluid.
D Pipe and dispose of the exhaust air safely, away from people, animals, and food handling areas. If the
diaphragm fails, the fluid is exhausted along with the air. See Air Exhaust Ventilation on page 10.
D Use static wire hoses when pumping flammables.
D Keep containers closed when not in use.
