Safety Precautions
14
Use the following First Aid practices if needed.
Eyes: Immediately flush eyes with large amounts
of water for at least 15 minutes while holding the
eyelids open. Get prompt medical attention.
Skin: Remove contaminated clothing. Wash
thoroughly with soap and water. Get medical
attention if irritation persists.
Inhalation: Move victim to fresh air and restore
breathing if necessary. Stay with victim until
arrival of emergency personnel.
Ingestion: Do not induce vomiting. Contact a
local poison control center or physician
immediately.
Electrical
High Voltage
When servicing or repairing a refrigeration unit,
the possibility of serious or even fatal injury from
electrical shock exists. Extreme care must be used
when working with a refrigeration unit that is
connected to a source of operating power, even if
the unit is not running. Lethal voltage potentials
can exist at the unit power cord, inside the control
box, inside any high voltage junction box, at the
motors and within the wiring harnesses.
Precautions
• Be certain the unit O
N/OFF switch is turned
O
FF before connecting or disconnecting the
unit power plug. Never attempt to stop the unit
by disconnecting the power plug.
• Be certain the unit power plug is clean and dry
before connecting it to a power source.
• Use tools with insulated handles that are in
good condition. Never hold metal tools in
your hand if exposed, energized conductors
are within reach.
• Do not make any rapid moves when working
with high voltage circuits. If a tool or other
object falls, do not attempt to grab it. People
do not contact high voltage wires on purpose.
It occurs from an unplanned movement.
• Treat all wires and connections as high
voltage until ammeter and wiring diagram
show otherwise.
• Never work alone on high voltage circuits on
the refrigeration unit. Another person should
always be standing by in the event of an
accident to shut off the refrigeration unit and
to aid a victim.
• 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 Pulmonary 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
emergency medical assistance.
