Electrical Safety Audit
Over 20% of fires which take place world wide and 40% of fireswhich occur in India are due to faulty electrical circuits. Electrical hazards continue to threaten the 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 should be managed effectively.
In process industries, fires arising from electrical faults are highly 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.
