Plan Electrical Safety Audit for Fire Safety

In the field of Electrical Engineering Safety, engineers and other professionals get exposed to electricity indirectly during generation, transportation, installation and usage. Such conditions might cause hazards if accurate safety measures aren't taken.

To promote the security and therefore the right usage of kit, there are certain rules and regulations formulated by the Bureau of Indian Standards (BIS). BIS follows the following five principles −

• Safety

• Ease of use and adaptability

• Simple technology

• Value for money products

• Energy efficiency and environment

BIS has published the following code for public safety standards in order to promote the right to information, transparency and accountability.
