Arc Flash is the result of a rapid release of energy because of arcing mistake between a phase bus bar and another phase bus bar, neutral or a ground. At the time of an arc fault the air is the medium. electrical explosion that gets to the temperature of 35,000 degree Fahrenheit which is an extreme degree of heat responsible for occurring severe injury to the employee by direct exposure. To cut down the possible numbers of injury, The National Fire Protection Agency (NFPA) presented to NFPA 70E, a standard for electrical safety in the work place. NFPA 70E takes care of electrical safety at electrical hazardous work place of arc flash by giving nfpa 70e fire safety clothing. There are different types of protective gear like:-
Flame Resistance Gear
High Visibility Gear
Flame Resistance Gear:-To put on appropriate arc flash flame resistance clothing (frc) on the job for electricians is because of exposure to sever heat and moreover impulsive burst. Importance of fire resistance clothing is to diminish accidents. Breathing ability, humidity management and moreover comfort are the safety features of flame resistance. It is contrived in such a manner so thta technician can move freely and easily in order to perform their job in the best way.
High Visibility Clothing:-High visibility clothing is usually utilized in dark or rainy conditions. This electrical fire safety clothing is indulged with powerful visibility standards. Employees can see clearly and avoid accidents because the jackets and vests of this clothing contains particular amount of fluorescent and reflective fabric.
The NFPA 70E also provides number of additional fire safety gear such as insulated gloves, durable eyewear, hoods sleeves and helmets. Only well trained linemen can understand the appropriate protective for a specific situation.
