SAFETY
There are hazards in servicing gensets. Study
Safety Precautions and become familiar with the
hazards listed in Table
5-1
. Note the following safe-
guards and ways of avoiding hazards:
• Use
personal
protection:
Wear appropriate
protective safety equipment, such as:
Safety shoes
Gloves
Safety glasses
Hard hats
Do not wear rings or jewelry and do not wear
loose clothing that might get caught
in
equip-
ment.
• Reduce the hazard: A safe, orderly workshop
area and well-maintained equipment reduce
the hazard potential. Keep guards and shields
in place on machinery and maintain equipment
in
good working condition. Store flammable liq-
uids
in
approved containers; away from fire,
flame, spark, pilot light, switches, arc-produc-
ing equipment and other ignition sources.
Keep the workshop clean and well-lighted and
provide adequate ventilation.
• Develop safe
work
habits: Unsafe actions
cause accidents with tools and machines. Be
familiar with the equipment and know how to
use it safely. Use the correct tool for the job and
check its condition before starting. Comply with
the warnings in this manual and take special
precautions when working around electrical
equipment. Do not work alone if possible and
take no risks.
•
Be
prepared
for
an
accident: Keep fire extin-
guishers and safety equipment nearby. Agen-
cies such as the Red Cross and public safety
departments offer courses
in
first aid, CPR and
fire control. Take advantage of this information
to be ready to respond to an accident. Learn to
be safety-conscious and make safety proce-
dures part of the work routine.
