Arc Flash Protection:

Wiha Insulated tools can be a vital component in your Arc Flash

protection strategy. What is Arc Flash?

ARC FLASH

An Arc Flash is an electrical explosion due to a fault condition or short

circuit when either a phase to ground or phase to phase conductor is

connected. Arc flashes cause electrical equipment to explode, result-

ing in an arc-plasma fireball. Temperatures may exceed 35,000° F (the

surface of the sun is 9000° F). These high temperatures cause rapid

heating of surrounding air and extreme pressures, resulting in an arc

blast. The arc blast will likely vaporize all solid copper conductors which

will expand up to 67,000 times its original volume when it is vaporized.

The result of this violent event is usually destruction of the equipment

involved, fire, and severe injury or death to any nearby people.

WHY ARC FLASHES HAPPEN

There are a variety of reasons why an Arc Flash can occur, but most

of them are preventable. Most arc flashes occur when maintenance

workers are manipulating live equipment for testing or repair and

accidentally cause a fault. Improper tools, improper electrical

equipment, corrosion of equipment, improper work techniques and lack

of training are just some of the events that can lead to a devastating

arc flash or arc blast.

ARC FLASH COMPLIANCE

There are 4 main regulations that govern electrical safety & arc flash:

OSHA Standards 29CFR, Part 1910. Occupational Safety and

Health Standards. 1910 sub part S (electrical) Standard number

1910.333 specifically addresses Standards for Work Practices and

references NFPA 70E. OSHA 29CFR 1910.335 (a) (1)(i) requires the

use of protective equipment when working where a potential electrical

hazard exists and 29CFR 1910.132(d)(1) which requires the employer

assess the workplace for hazards and the need for personal protective

equipment. OSHA compliance is required by any plant building or facility.

The National Fire Protection Association (NFPA) Standard 70 -

2002 “The National Electrical Code” (NEC) contains requirements for

warning labels.

3. NFPA 70E provides guidance on implementing appropriate work

practices that are required to safeguard workers from injury while

working on or near exposed electrical conductors or circuit parts that

could become energized. Part II 2-1.3.3 regarding Arc Flash Analysis

states that a “Flash Hazard Analysis shall be done before a person

approaches any exposed electrical conductor or circuit part that has

not been placed in an electrical safe work condition”. This Arc Flash

Hazard Analysis must be done to determine the level of Personal

Protection Equipment PPE that a worker must use, and the Arc Flash

Boundary in inches along with the incident energy found at each

location. Each panel must be marked with an ANSI z535 approved Arc

Flash Warning Label.
