What is Arc Flash Insulated Open End Spanners 4-5 ARC FLASH An Arc Flash is an electrical explosion due to a fault condition or short Insulated Ratchet Wrenches 5 circuit when either a phase to ground or phase to phase conductor is connected. Arc flashes cause electrical equipment to explode, resulting Ins. Offset Ring Wrenches 6 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 Wiha Insulated Adjustable Wrenches will expand up to 67,000 times its original volume when it is vaporized. Description Page The result of this violent event is usually destruction of the equipment involved, fire, and severe injury or death to any nearby people. Insulated Adjustable Wrenches 7 WHY ARC FLASHES HAPPEN 8.0, 10.0, 12.0, 15.0 There are a variety of reasons why an Arc Flash can occur, but most of them are preventable. Most arc flashes occur when maintenance Wiha Insulated Electricians Knives workers are manipulating live equipment for testing or repair and accidentally cause a fault. Improper tools, improper electrical Description Page equipment, corrosion of equipment, improper work techniques and lack of training are just some of the events that can lead to a devastating Insulated Knives 7 arc flash or arc blast. ARC FLASH COMPLIANCE Wiha Insulated L-keys There are 4 main regulations that govern electrical safety & arc flash: Description Page 1. OSHA Standards 29CFR, Part 1910. Occupational Safety and Health Standards. 1910 sub part S (electrical) Standard number Insulated L-keys 8 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 Wiha Insulated 3/8 Hex Drive Bit Sockets equipment. OSHA compliance is required by any plant building or facility. Description Page 2. The National Fire Protection Association (NFPA) Standard 70 - 2002 The National Electrical Code (NEC) contains requirements for Ins. Hex Drive Bit Sockets 9 warning labels. 3. NFPA 70E provides guidance on implementing appropriate work practices that are required to safeguard workers from injury while Wiha Insulated Socket Accessories working on or near exposed electrical conductors or circuit parts that Description Page 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 Insulated Sockets 1/4, 3/8, 1/2 9-12 not been placed in an electrical safe work condition. This Arc Flash Hazard Analysis must be done to determine the level of Personal Insulated Ratchets 10-13 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 Insulated T-handle 10-13 Flash Warning Label. Insulated Extension Bars 10-13 4.
