Safety Precautions
13
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.
Low Voltage
Control circuits are low voltage (24 Vac and 12
Vdc). This voltage potential is not considered
dangerous, but the large amount of current
available (over 30 amperes) can cause severe
burns if shorted to ground.
Do not wear jewelry, watch or rings. These items
can short out electrical circuits and cause severe
burns to the wearer.
General Safety Precautions for
Servicing Units (or Containers)
Equipped with a
Microprocessor Controller
Precautions must be taken to prevent electrostatic
discharge when servicing the microprocessor,
controller and related components. If these
precautionary measures are not followed, the risk
of significant damage to the electronic
components of the unit is possible.
The primary risk potential results from the failure
to wear adequate electrostatic discharge
preventive equipment when handling and
servicing the controller. The second cause results
from electric welding on the unit and container
chassis without taking precautionary steps.
