4-2-1 Safety Precautions
There will be dangers during repairing the generator unit.
Read safety precautions carefully and be familiar with
the dangers listed in Table 4-1. Note the safety measures
and methods of the following danger preventions.
Use personal protective equipment: wear proper
safety protective equipment, such as safety shoes and
protective glasses.
Do not wear earrings or jewelry; do not wear loose or
wet clothes as they may be caught in the equipment or
cause electric shock.
Reduce risk: a safe workshop in order and under good
maintenance can reduce potential risks. The protective
equipment and shield of machinery shall be installed in
place and be kept at normal position so as to keep
equipment be under the good operation. Flammable
liquid shall be stored in approved container, and be kept
away from open fire, sparks, pilot torches, switch,
equipment generating electric arcs as well as other
ignition sources. The workshop must be kept clean with
sufficient lighting and adequate ventilation.
Develop the habit of safe operation: unsafe behavior
will cause equipment and machinery accidents. Be
familiar with equipment and the methods how to use
them safely. Use correct tools during operation and
check the status before starting. Follow the warnings
mentioned in the Manual and take special precautions
when working near electrical equipment. If possible, do
not work alone and take risks.
Be prepared for dealing with accidents: prepare a fire
extinguisher and safety equipment at the place near
yourself. Red Cross and public safety agencies have
provided some courses in term of first aid, CPR and fire
control. Make use of these materials to prepare well to
deal with accidents. Learn how to possess safety
consciousness and treat safety rules as a part of routine
work.
