ELECTRICAL HAZARDS
High Voltage
When servicing or repairing a refrigeration unit, the possi-
bility of serious or even fatal injury from electrical shock
exists. Extreme care must be used when working with an
operating refrigeration unit. Lethal voltage potentials can
exist on connections in the high voltage tray of the control
box.
Precautions
1. When working on high voltage circuits on the refrigera-
tion unit, do not make any rapid moves. If a tool drops,
do not grab for it. People do not contact high voltage
wires on purpose. It occurs from an unplanned move-
ment.
2. Use tools with insulated handles that are in good condi-
tion. Never hold metal tools in your hand if exposed,
energized conductors are within reach.
3. Treat all wires and connections as high voltage until a
meter and wiring diagram show otherwise.
4. Never work alone on high voltage circuits on the refrig-
eration unit, another person should always be standing
by in the event of an accident to shut off the refrigera-
tion unit and to aid a victim.
5. Have electrically insulated gloves, cable cutters and
safety glasses available in the immediate vicinity in the
event of an accident.
First Aid
IMMEDIATE action must be initiated after a person has
received an electrical shock. Obtain immediate medical
assistance if available.
The source of shock must be immediately removed by
either shutting down the power or removing the victim from
the source. If it is not possible to shut off the power, the wire
should be cut with either an insulated instrument (e.g., a
wooden handled axe or cable cutters with heavy insulated
handles) or by a rescuer wearing electrically insulated
gloves and safety glasses. Whichever method is used do not
look at the wire while it is being cut. The ensuing flash can
cause burns and blindness.
If the victim has to be removed from a live circuit, pull the
victim off with a non-conductive material. Use the victim’s
coat, a rope, wood, or loop your belt around the victim’s leg
or arm and pull the victim off. DO NOT TOUCH the victim.
You can receive a shock from current flowing through the
victim’s body. After separating the victim from power
source, check immediately for the presence of a pulse and
respiration. If a pulse is not present, start CPR (Cardio Pul-
monary Resuscitation) and call for emergency medical
assistance. If a pulse is present, respiration may be restored
by using mouth-to-mouth resuscitation, but call for emer-
gency medical assistance.
Low Voltage
Control circuits used in the refrigeration unit are low volt-
age (12 volts dc). This voltage potential is not considered
dangerous, but the large amount of current available (over
30 amperes) can cause severe burns if shorted or ground.
Do not wear jewelry, a watch or rings. These items can short
out electrical circuits and cause severe burns to the wearer.
