ELECTRICAL SAFETY AUDIT
Manage Risks Profitably

2. WHY ELECTRICAL SAFETY AUDITS
As Per FPA, UK & NFPA, US, 25% Of fires Are Due to Electrical Installations.
Indian Scenario- 40% fires due to Electrical Causes
8 % Fatalities in Indian Factories Are Due to Electrical Causes

3. STATUTORY REQUIREMENT
Indian Electricity Rule # 29
(1) “All Electric Supply Lines & Apparatus Shall be of Sufficient Ratings for Power, Insulation and Estimated Fault current and of Sufficient Mechanical Strength, for the Duty Which They May Be Required to Perform Under The Environmental Conditions of Installation, and Shall be Constructed, Installed Worked and Maintained in Such a Manner so as to Ensure Safety of Human Beings, Animals and Property”.
(2) “The Relevant Code of Practice or the BIS If any may be followed to carry out the purpose of this Rule and in the Event of any Inconsistency, the provision of this Rule Will Prevail”.

9. ELECTRICAL SAFETY AUDIT MAJOR FINDINGS
Elevation of buildings & structures-not considered for LP design
Protection relays- deviation from original design settings
RCCBs- wrong sensitivity,bypassing & location
Earth continuity- not tested
Use of ordinary copper wire in fuses
Statutory violations

10. FINDINGS…. EPM system- heavy slippage in implementation
Electrical accident investigation- Root cause rectification exercise not carried out
LHS cable ineffective installation practice
Passive fire protection inadequacies
Hotspots in LDB due to unequal load balancing
No updated reference drawing
Wrong earth pit identification
Flameproof Equipment maintenance
Tracking problem in MCCs due to dust deposits

11. FINDINGS…. OLTC- counter meter readings not taken
Cables added w/o considering derating factors
Insufficient baffle wall height between transformers
Wrong OTI/WTI Setting
Wrong feeder identification
