Safety Precautions
General Practices
1. Always Wear Goggles Or Safety Glasses.
Battery acid can permanently damage the eyes
(see First Aid under Battery Hazards).
2. Keep your hands, clothing and tools clear of
all fans, pulleys and belts when the unit is
running. Be very careful with tools or meters
to avoid contacting the rotor, if it is necessary
to run the alternator with the end cover
removed.
3. Be sure all mounting bolts are tight and the
correct length for their particular application.
4. Use extreme caution when drilling holes in the
unit. The holes may weaken structural
components. Holes drilled into electrical
wiring can cause fire, explosion or shock
hazard.
5. Use caution when working around exposed
coil fins. The fins can cause painful
lacerations.
6. Do not work on a generator set in a confined
area. Diesel exhaust can become very
dangerous under certain conditions.
Battery Hazards
Few people realize just how dangerous a battery
can be. The electrolyte in a lead acid battery is
dilute sulfuric acid (H
2
SO
4
). During charge or
discharge functions of a battery, a chemical
change takes place within the individual cells.
This causes the gas bubbling we see through the
filler hole. The bubbling gases are hydrogen and
oxygen. They are EXPLOSIVE. An explosion
could occur if a means of ignition is present
during this gassing action. A defective battery
may suddenly explode even while standing idle.
Added to this danger, is the fall-out of highly
corrosive sulfuric acid caused by the explosion. A
rubber blanket or other cover can be used to
reduce the risk of injury from a possible
explosion.
Precautions
1. Always wear eye protection when servicing a
battery. If electrolyte is splashed on the skin or
in the eyes, flush immediately under running
water. Obtain medical help as soon as
possible.
2. Do not remove the vent caps when charging a
battery.
3. Make sure the On/Off switch is in the OFF
position when disconnecting or connecting the
generator set battery. This will prevent an
electrical arc which could cause the battery to
explode. Disconnect the ground cable first,
preferably at a point AWAY FROM THE
BATTERY. Connect the ground cable last,
again away from the battery if possible.
4. Do not check a battery by shorting (sparking)
across the battery posts. Eye injury may result
from the electrical arc or from an explosion.
First Aid
•
EYES: Immediately flush eyes with large
amounts of water while holding the eyelids
open for at least 15 minutes. Get prompt
medical attention.
•
SKIN: Remove contaminated clothing. Wash
thoroughly with soap and water. Get medical
attention if irritation persists.
Electrical Hazards
High Voltage
The possibility of serious or even fatal injury from
electrical shock exists, when servicing or
repairing a generator set, Extreme care must be
used when working with an operating generator
set. Lethal voltage potentials can exist at the unit
power cord, inside the exciter control box, inside
any high voltage junction box and within the
wiring harnesses.
