disposal procedures, check with your safety
Store flammable solvents only in approved
flammable storage lockers. Be sure to store
flammable and corrosive materials separately.
NEVER use carbon tetrachloride. Carbon
tetrachloride is a highly toxic compound and is
banned from use. Use trichloroethane instead.
NEVER smoke or use an open flame or allow
anyone else to do so in areas where paint,
varnishes, lacquers, or solvents are being used.
NEVER breathe the vapors of any cleaning
solvent for prolonged periods. If you dont have
proper ventilation, use proper PPE.

NEVER spray cleaning solvents onto electrical
windings or insulation.
NEVER apply cleaning solvents to heated
equipment. Doing so could cause a fire.
Aerosol containers are everywhere. When used
properly, aerosol containers dispense their chemicals
quickly and effectively. But if you misuse them, they
can hurt you and cause damage to your surroundings.
To prevent this, you must be aware of the dangers
associated with aerosol containers and how to protect
yourself from those dangers.
Before you use any aerosol container, read its
label. The label usually has instructions on how to use,
store, and dispose of the container safely. Do not
ignore these instructions. If you do, you may become
ill from the toxic effects of the chemicals in the
container. Even worse, you may be seriously injured if
the container explodes.
Here are some basic rules to follow when using
Ventilation: Ensure that you have plenty of
ventilation when you use aerosols that contain
dangerous or toxic gases. If you must use such aerosols
when ventilation is not adequate, wear the appropriate
Heat Sources: Keep all aerosol containers away
from open flames, sunlight, heaters, and other possible
sources of heat. Do not smoke in areas where aerosols
are being used.
Disposition: NEVER discard aerosol containers
in wastebaskets that will be emptied into an
incinerator, as they could explode. Dispose of the
containers according to the MSDSs instructions.
Some aerosol containers are considered hazardous
Paint: NEVER spray paint or other protective
coatings onto warm or energized equipment, as you
may cause a fire.
Skin: NEVER spray paints or solvents onto your
skin. Some liquids in aerosol containers may burn you;
others may cause a skin rash.
Dents/Punctures: NEVER dent or puncture
aerosol containers. Since they are pressurized, they
may explode if they become dented or punctured.
Temperature: NEVER store aerosol containers in
heated areas where temperatures can exceed the
recommended storage temperature on their labels.
Aboard ship, all aerosols are considered flammables
and must be stored in a flammable liquid storage
compartment or cabinet.
Polychlorinated biphenyls (PCBs) are toxic
chemicals of the chlorinated hydrocarbon group. They
range in form and appearance from oily liquids, to
crystalline solids, to hard transparent resins. These
chemicals exhibit many favorable physical and
chemical properties, including high heat capacity,
chemical stability, noncorrosivity to metals, low
flammability, low vapor pressure, and low electrical
conductivity. Therefore, they are used extensively as
insulators and coolants in electrical equipment.
PCBs in use aboard ship typically function as
insulating fluids or coolants in electrical equipment.
(The chemicals might occasionally be found in totally
enclosed hydraulic and heat transfer systems.)
Remember, these chemicals are toxic. That means
they can be harmful to your health (perhaps deadly.)
Their adverse effects can result from either brief or
repeated exposure. The effects from short-term contact
with high concentrations of PCB vapors or liquids
include eye, nose, and throat irritation; headaches; and
the skin rash chloracne. Repeated exposure can result
in severe skin irritation, respiratory irritation, digestive
tract damage, and liver damage. Systemic intoxication
