4-2 Preparing to Service
4-2-1 Safety Precautions
There are hazards in servicing gensets. Study
Safety precautions and become familiar with the
hazards listed in table 4-1. Note the following
safeguards and ways of avoiding hazards.
•
Use personal protection:
Wear appropriate
protective safety equipment, such as safety shoes
and safety glasses.
•
Do not wear rings or jewelry and do not wear
loose or damp clothing that might get caught in
equipment or conduct electricity.
•
Reduce the hazard:
A safe, orderly and
well-maintained workshop reduces the hazard
potential. Keep guards and shields in place on
machinery and maintain equipment in good working
condition. Store flammable liquids in approved
containers; away form fire, flame, spark, pilot torch,
switches, arc-producing equipment and other
ignition sources. Keep the workshop clean and
well-lighted and provide adequate ventilation.
•
Develop safe work habits:
Unsafe actions cause
accidents of tools and machines. Be familiar with
the equipment and know how to use them 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
extinguishers and safety equipment nearby.
Agencies 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 procedures part
of the work routine.
