How to control Electrical Safety Risk?
About the presentation
Electrical Safety is a concern in almost every
organizations. The risks related to electrical
safety are often managed in an isolated way.
www.verde.co.in
This presentation will help organisations to
manage Electrical Safety risks in a more
structured fashion.
www.verde.co.in
1. Establish an Electrical Safety Program
2. Publish an Electrical Safety Manual
3. Perform a Site Assessment
4. Identify and Document Hazards
5. Conduct an Electrical Hazard Analysis (Shock, Arc Flash
& Arc Blast)
6. Establish Flash Protection Boundaries

7. Outline PPE Requirements
8. Apply Appropriate Warning Labels
9. Conduct Employee Training
10. Audit & Update on a Regular BasisSteps to a Safer Workplace

Why Electricity is dangerous?
Electricity can be dangerous because:
• People need to use or work with electricity all the times
www.verde.co.in
• As a form of energy it can seriously harm people when electrical current passes
through the human body
As a form of energy, electricity is an invisible danger
Hazards in electricity
• Electric Shock
• Fire and Explosion
• Joule’s Burn
• Arc Flash & Arc blast
• Fall from height

• Fall from height
• Fall of hand held working tools
• Direct burn from electric arc welding
• U/V & Infra-red Radiation burns to eyes from arc welding
• Eye injury from electric arcs (e.g. Welder’s eye flash)
• Physical injury from false starting of machine,
• Explosion of switch gears etc

Physiological effects of electricity
• Generation of Heat – Most basic and easy-to-understand effect of electricity onliving tissue; current make it heat up. If the amount of heat generation is sufficient, thetissue may be burnt. Electricity has the ability to burn tissue well beneath the skin ofvictim, even burning internal organs.
• Electric shock – Effect of electric current on body in terms of hazard, affects nervecells that process and conduct the multitude of signals responsible for regulation of

cells that process and conduct the multitude of signals responsible for regulation ofmany body function together to allow it to sense, move, respond, think, andremember.
• Effect on nervous system – Electric current of sufficient magnitude effect nervoussystem and prevent both human reflex and muscles. Contraction of muscles occurwhen a victim contacts an energized conductor with his hands. Clenching action forcethe hand to grasp the wire firmly, thus worsening the situation securing better contactwith the wire. Medically this condition of muscle contraction is called tetanus.
Electrical Safety is an ongoing challenge
for Industries.
www.verde.co.in
for Industries.
How can you prevent loss and protect
yourself and your workplace?
By using one or more of the following measures in the field of electrical safety. i.e.
www.verde.co.in
• Electrical Safety Audit
• Lightning & Surge Protection Audit
• Electrical & Fire Safety Audit
• Hazardous Area Classification (HAC)
Why??
• Electrical Safety Audit – Electrical Safety Audit is an effective tool to identify
potential electrical hazards, flaws in design system, maintenance system and to
provide suitable remedial measures in order to control risks exists in your electrical
system.
www.verde.co.in
• Lightning & Surge Protection Audit– Lightning and Surge Protection Audit is an
effective tool to identify and assess existing lightning protection system (if any) in the
premises and suggesting suitable measures to bridge the gap. This can protect your
workplace from the adverse effect lightning and surge.
Why??
• Electrical & Fire Safety Audit- Electrical & Fire Safety audit is an effective tool for
assessing electrical & fire safety status in your workplace. This audit helps to identify
the areas for improvement in electrical & fire safety measures in prevention,
protection and mitigation system in case of electrical fire.
www.verde.co.in
• Hazardous Area Classification (HAC)– Hazardous area can also be classified as
those locations where electrical equipment might be installed and which, by their
nature, might present a condition which could become explosive. HAC will help you to
ensure that the electrical equipment is properly selected, installed, operated and
maintained to provide a safe system.

Electrical Safety Audit
Do You Know??
• According to Fire Protection Association (FPA) UK and National Fire Protection
Association (NFPA) USA , globally in industries, around 8% of all fatalities are due to
accidents caused by electricity.
www.verde.co.in
• In India over 40% of the fire incidents are initiated by electrical causes such as short
circuits, overloading, loose electrical connections.
Electrical Safety Audit?
• Independent Electrical Safety Audit is an effective way of managing the loss by
identifying both good practices and areas for improvement within an organisation’s
electrical safety management system.
www.verde.co.in
It is true that electrical hazards can be identified and assessed in general safety audit,
but comprehensive electrical safety audits can provide a thorough review of electrical
system which can also identify potential electrical hazards, flaws in design system,
maintenance system etc in your workplace.
Electrical Safety Audit
Electrical Safety Audit is carried out by way of physical examination, sample
www.verde.co.in
examination, sample tests, review of records and discussion with various departments & plant personnel
Electrical Safety Audit Objectives
• To ensure that electrical safety system fully satisfy the legal requirements
• To review and critically assess the existing electrical safety system to prevent and
control
www.verde.co.in
• the hazards in the facility with a view to suggest improvement
• To recommend the measures for improving effectiveness for implementation of
electrical safety systems, procedures, plans and programs and also for improving the
existing procedures / setting of new procedures if required
Standards & Codes followed during
Electrical Safety Audit
• Electricity Act, 2003
• Indian Electricity Rules, 1956 (Amended 2005)
• Central Electricity Authority Regulations, 2010
• Relevant NFPA Codes
www.verde.co.in
• Relevant NFPA Codes
• Relevant OISD Standards
• Relevant Indian Standards
• Best Engineering Practices
• Industrial Best Practices
General Scope for Electrical Safety Audit
• Verification of statutory compliance with respect to the regulations (national
and state level) relating to electrical safety.
www.verde.co.in
• Review of electrical systems and procedures usually followed and physical
inspection to identify electrical hazards like fire, overloading.
• Identify areas of overloading by load current assessments and comparing
against cable’s current carrying capacity to suggest electrical safety solutions.
General Scope for Electrical Safety Audit Cont…
•Review of insulation status of cables by carrying out sample basis insulation resistance
checking.
www.verde.co.in
•Review of hazardous area and suggestion for flameproof electrical equipment & fire
resistant cables.
•Review of electrical preventive maintenance system (checking of documentations) for
necessary suggestions and review of electrical accidents if happened in the past to
identify the root causes and suggestions.
•Review of lightning protection system (need, adequacy, installation and maintenance) as per standard norms.
•Review of earthing system (installation and maintenance aspects) to realize present safety status and providing necessary suggestion.
