Indian Standards for Electrical Safety Audit
Introduction
Electrical Safety, if not done or followed properly can lead to severe damages. More than forty percent of total fire hazard is due to compromise in electrical safety. It is critical to get the electrical safety audit done for your premises on a regular basis otherwise it can harm people and properties due to Burns, Shock, Fire, Blasts, etc. and in some cases, it forces business owners to shut shops.

Indian Standard
The Bureau of Indian Standards (BIS) has laid down rules and regulations to be followed for a safety audit. These guidelines are regulated by the Central Electricity Authority ( http://www.cea.nic.in/) and the National Safety Council of India (http://www.nsc.org.in/)
We have listed down a few application-wise Indian Standards ( IS )which can be referred for the specific application.
