![]() There exists a number of ways to protect workers from the threat of electrical hazards. Some equipment will have a greater flash protection boundary while other equipment will have a lesser boundary. This distance is not common between equipment. Prohibited Approach (inner boundary)Ī distance from an exposed part which is considered the same as making contact with the live part. Restricted Approach BoundaryĪn approach limit boundary is the distance from an exposed live part where a shock hazard is immanent. Limited Approach BoundaryĪn approach limit boundary is the distance from an exposed live part where a shock hazard may exist. The issue here is the heat generated from a flash that results in burns. If an arc flash occurred, this boundary is where an employee would be exposed to a curable second degree burn (1.2 calories/cm2 ). These boundaries are: Flash Protection Boundary (outer boundary)Īn arc flash boundary is the farthest established boundary from the energy source. The National Fire Protection Association (NFPA) has developed specific approach boundaries designed to protect employees while working on or near energized equipment. Sound Blast (noise can reach 140 dB – loud as a gun).Fire (could spread rapidly through building).Burns (Non FR clothing can burn onto skin).It’s not uncommon for an injured employee to never regain their past quality of life. Three factors determine the severity of an arc flash injury:īecause of the violent nature of an arc flash hazard when an employee is injured, the injury is serious – even resulting in death. Arc flash occurs by many things including: ![]() Rather than flowing through a conductor, the current flows through the air, which releases thermal energy into the immediate environment. An arc blast occurs as the result of a malfunction in the insulation between two energized phase conductors on high powered electrical equipment. What is Arc PPE?Īrc flash PPE is arc rated personal protective equipment worn by workers performing maintenance on energized equipment as well as de-energizing equipment and is the last line of defense to protect workers from arc flash injuries What Does Arc Blast Mean?Īn arc blast is the name given to the explosive burst of energy that occurs during an arc flash. The results are often violent and when a human is in close proximity to the arc flash, serious injury and even death can occur. Simply put, an arc flash is a phenomenon where a flashover of electric current leaves its intended path and travels through the air from one conductor to another, or to ground. The focus of this webinar is on major changes to the standard and their implementation in EasyPower.19 How do you protect someone from arc flash? Your Guide to the Best Arc Flash Protection Following publication, this second edition of the widely adopted industry standard includes an entirely new arc flash model with revised procedures and calculations to predict arc flash hazard levels. This webinar, given by Greg Pagello at EasyPower, is an introduction to changes in the new IEEE 1584-2018 Guide for Performing Arc Flash Hazard Calculations recently, approved by the IEEE Standards Association.
