How to Properly Use Arc Flash Personal Protective Equipment

This 2 minute safety training video covers: Arc flash PPE, importance of "arc-rated" protective clothing, how to calculate "arc-rating" for a particular test, how to determine the Arc-Rating for Clothing, what are the physical hazards of arc flash and hazards of an arc blast.

We want to make a distinction of personal protective equipment to hazards applies to arc flash and boundary assessments. It's much more than wearing gloves and safety glasses. Examples of the equipment could include a hard hat, face shield, flame resistant neck protection, ear protection, insulated rubber gloves with leather protectors and insulated leather footwear. NFPA 70E has specific requirements for PPE depending upon the potential hazard. Protective equipment, sufficient foot protection for electrical flash will be required for any part of the body which could be within 3 feet of the fault, that is why the assessment is so important in establishing boundaries to select the appropriate PPE that will protect you in the event of a flash. The common distance used for most low voltage incident energy research and testing is at 18" from the arching fault source. If a person is closer than 18", the higher the incident energy and blast hazard. In other words if the body has sufficient PPE for an 18" working distance, severe injury can result to any part of the body closer than 18" to the source of the arc.
