Over 20% of fire world wide and 40% fire in India are due to faulty electric circuits. Electricity hazard continue to threaten safety of people and property in the form of shocks, burns, injury, fire and explosion. With electricity having become an indispensable part of our life, electrical risks are to be managed effectively.
In process industries, fires due to electrical reasons are very probable, especially in industries that handle flammable chemicals. In service industries such as information technology, telecommunications, business interruption losses due to electrical hazards (fire in server room, damage of expensive communication equipment, loss of data, fire in cable gallery, etc.) could be substantial.
NECPL team carry out electrical safety audit in a systematic procedure to evaluate potential electrical hazards, and recommends measures to minimize /prevent these hazards (i.e. electrical shocks, electrical arcs, and electrical blasts). Our electrical safety audit study is a loss prevention program - property/production loss (e.g. electrical fire hazards) and loss of life/injuries to personnel.
Typical Scope of Study
Verification of statutory compliance with respect to Indian Electricity rule.
Physical inspection to identify electrical hazards (shock, fire, explosion, overloading) and to suggest electrical safety solutions
Review of plant lightning protection system (need, adequacy, installation and maintenance)
Review of static electricity hazards in the plant operations (if applicable)
Review of hazardous area classification and selection of flameproof electrical equipment in the plant, including maintenance aspects (if applicable)
Review of electrical preventive maintenance system (including tests, documentation, history cards, etc).
Review of electrical accidents and near misses in the plant to identify the root causes
Review of electrical systems & procedures (work permits, interlocks, lockout tags, etc).
Review of the importance given to electrical safety in the company safety policy, safety committee, continuous electrical risk identification, etc.
Assessing the integrity of insulation of cables by carrying out insulation resistance tests on a sample basis
Review of the earthing system (installation & maintenance aspects), including sample earth resistance tests
To identify areas of overloading by carrying out load current measurements and compared against cable current carrying capacity calculation
Hotspot detection using infra-red hot spot detection equipment/ thermal imaging (as necessary)
After carrying out the electrical safety audit, report includes observation and hazard identified and remedial action to be taken to eliminate the hazard
