20.3 HAZARDS ARISING FROM ELECTRICAL FAULTS
20.3.1 SAFETY STANDARDS FOR ELECTRICAL EQUIPMENT
Introduction
The causes of electrical risks are well known and it is not difficult to prevent these risks by
applying constant care and attention.
Assigned personnel must be informed regarding potential dangers and trained regarding
safety procedures in order to reduce the number of potential electrical accidents.
20.3.2 TASKS ASSIGNED TO PLANT MANAGERS
Plant managers must be informed regarding potential risks in the system and must
superintend personnel that works with electrical equipment.
Superintending tasks consist of localizing possible risk situations and investigating
problems encountered by personnel when performing maintenance.
Each defective component must be immediately repaired or replaced.
The manager must insist on application of safety measures. He must not tolerate or accept
deviations from these because this could cause harm to persons or to the machinery.
20.3.3 HIGH VOLTAGE
Contact with high voltage circuits can cause burns, shock, unconsciousness or even death
for the persons involved.
This problem can be caused by poor understanding of the dangers inherent to use of
electrical device s.
Damage to the human body, in this case, depends on the intensity of current, the duration
of current and the path the current takes as it goes through the body.
20.3.4 SAFETY STANDARDS TO COMPLY WITH WHEN THE EQUIPMENT IS
SWITCHED OFF
Interrupt the power supply to the unit before opening it.
Make sure no electricity is present in the unit's circuits.
Clean and dry the work area.
Remove dowels, rings, brackets or metal parts which can hamper the job to be done or
become potential conductors for electricity.
Ground or short-circuit the terminals of the fan capacitors in the de-energized circuit.
Remove fuses only after the circuit has been deactivated.
20.3.5 SAFETY STANDARDS TO COMPLY WITH WHEN PERFORMING MAINTENANCE
ON LIVE
The following standards must be complied with, in addition to those stated at point 19.3.4
above:
· personnel must never work alone;
· work should be done, if possible, using only one hand;
· use only authorized procedures to perform by-passes at interlocks;
· make sure assigned personnel are perfectly familiar with the machine's components and
