Safety Precautions 2-4
Precautions
1. Be certain the unit On/Off switch is turned OFF before connecting or disconnecting the standby power plug. Never attempt
to stop the unit by disconnecting the power plug.
2. Be certain the unit power plug is clean and dry before connecting it to a power source.
3. When working on high voltage circuits on the temperature control 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 movement.
4. Use tools with insulated handles that are in good condition. Never hold metal tools in your hand if exposed, energised
conductors are within reach.
5. Treat all wires and connections as high voltage until a meter and wiring diagram show otherwise.
6. Never work alone on high voltage circuits on the temperature control unit. Another person should always be present to shut
off the temperature control unit and provide aid in the event of an accident.
7. 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 cardiopulmonary 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.
