9.0 PROCEDURE

9.1 Preventing Electrical Hazards
There are three primary methods of protection from a potential electrical hazard.

9.1.1 Personal Protective Equipment (PPE)

9.1.2 Proper Grounding

9.1.3 Safe Work Practices

9.2 Personal Protective Equipments (PPEs)

9.2.1 Personal Protective Equipment (PPE) will be issued to employees to insulate them from potential shock. The proper use of rubber gloves (11KV grade for medium and high voltage & 1.1 KV grade for low voltage upto 1.1KV), insulated shoes and insulated tool can provide a measure of protection for employees working on an electrical circuit

9.2.2 Fire extinguisher suitable for dealing with electrical fire should be kept in generating station.

9.2.3 First aid boxes should be kept ready and accessible.

9.3 Grounding

9.3.1 Grounding is another method of protecting employees from electrical shock. Grounding is a critical form of protection that connects the equipment to the earth. During the short circuit, the excessive current will be allowed to pass through the earth and it also allows us to operate the over current devices in the circuit.

9.3.2 Most equipment and machines are grounded. Make a habit of checking grounds to make sure they are still connected and effective.

9.4 Safe Work Practices

9.4.1 Hot work and General work permit requirements (SOP INM-03-007) & Lock out and tag out (Refer to SOP INM-03-019 for details) procedures are to be followed strictly.

9.3.1 Qualified Electrical Technician
Only qualified electrical technician (Certificate issued by the approved institution, e.g. Institute of Technical Education) or other similarly trained competent person are allowed to work on such equipment.

9.4.3 Working with energized systems
Check all built-in safety features and remember that live-circuit work hazards are dangerous. Only (trained) qualified employee is allowed to attend to such systems.

9.4.4 Ensure that extension socket outlets used are checked for correctness of polarities and damages on the cable insulated Avoid laying the flexible cable at places where it may create a stumbling or tripping hazard (Industrial Electricity Rule 1956, Rule 38).

9.4.5 Ensures suitable cut out in each conductor of every service line other than earthed or earthed neutral conductor [Industrial Electricity Rule 1956, Rule 31, (2)].

9.4.6 Low, Medium, High and Extra-high voltage should have DANGER notice on a fixed position with a sign of skull and bones (Industrial Electricity Rule 1956, Rule 35).

9.4.4 If light is to be used inside any equipment for maintenance etc, it should be of less than or equal to 24 V DC only.

9.4.5 Every learning incident and accident should be reported as per SOP INM-03-008 (Accident and Learning Incident Investigation) through Accident/ injury reporting form (INM-03-008-1) and learning incident reporting form (INM-03-008-02).
