Electrical Studies

Electrical hazards continue to threaten safety of people and property in the form of shocks, burns, injury, fire and explosion. As electricity has become an indispensable part of our life, electrical risks are to be managed effectively.

Any disruption in the electrical system can bring the complete industry to a stand-still, thus making it a highly critical part of any installation. 

• 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, fire in cable gallery, damage of expensive communication equipment, loss of data, etc.) could be substantial.

Methodology:

1. Pre Site Visit data
2. Opening meeting
3. Pre Audit questionnaire
4. Physical Inspection
5. Discussion
6. Document review ( Standards and Emergency Response Plan)
7. Closing meeting
8. Report and observation submission.

Hazard Area classification is a method of analyzing and classifying the environment where explosive gas atmosphere may occur.

Review of likelihood of occurrence of explosive atmospheres and their persistence.

Classification of zones as explosive, less explosive etc. based on IEC – 60079-10 standard.

Static electricity presents a prospective source of ignition and can cause fires and explosions where flammable atmospheres, such as solvent vapors or dust clouds can occur.

We carry out extensive surveys to detect static charge present and provide prevention and control measures.

Review of Lightning Protection System specification & existing lightning protection against various standards like IS 2309, NFPA 780, OISD 180

Thermography is used to see the excess heat (resistance) so that problems can be found and maintenance personnel can act to correct the problem before the component fails, that can lead to cause damage to the component, safety hazards and/or production downtime.

Following are the steps to Thermography Monitoring

-To carry out ‘hot spot analysis’ of electrical system.

-Conditional monitoring of all electrical equipment.

- To furnish detailed report on findings of these reviews with photograph’s.

An arc flash occurs when an electrical path is broken in some way and the electricity jumps or “arcs” to a nearby grounded object.

Arc Flash analysis is a study of a facilities electrical system. This Study will determine potential weak spots throughout the electrical system, spots that would pose the danger of electrocution, electrical incidents, and even electrical arc blasts.

We refer to the NFPA 70E Standard & Guidelines.
