I have been told that most electrical work I do falls within Arc Flash PPE Category 2, is that accurate?

I have been told that most electrical work I do falls within Arc Flash PPE Category 2, is that accurate? No, it is impossible to know what protection is necessary without first completing an arc flash risk assessment. While it is true that the majority of energized work does fall within Arc Flash PPE Category 2 or have thermal incident exposure values below 8 cal/cm2, you can’t assume anything. You must use either the Incident Energy Analysis Method or Arc Flash...

If we don’t do any high voltage work, what type of PPE do we need?

If we don’t do any high voltage work, what type of PPE do we need? Voltage does not determine the arc flash hazard. Knowing the voltage is only one piece of determining Arc Flash PPE. The electrode orientation, available fault current (amps), the working distance between the worker and the equipment, the clearing time of the circuit protection device, the spacing between conductors or from a conductor to ground, the number of phases, whether the conductors are in an enclosure, and...

What fabric is the best for arc flash clothing?

What fabric is the best for arc flash clothing? There are three different types of arc-rated flame resistant (FR) fabrics available on the market; Treated non-inherently FR fabrics, Inherently FR fabrics and Treated Inherently FR fabrics. Treated non-inherently FR fabrics, either 100% cotton, or cotton blends, have no flame resistant properties and require a chemical treatment application to become flame resistant (FRT). Inherent fabrics are engineered to be flame resistant (IFR), and there is no chemical that needs to be added...

How do the arc-rated clothes actually protect me?

How do the arc-rated clothes actually protect me? Arc Flash PPE is tested to determine its protective ability, this is called an arc rating. This testing is done on the fabric or a finished product using various different testing methods according to applicable Standards. Arc-rated clothing provides insulation that protects a worker from the thermal incident energy caused by an arc flash incident. There are various different types of arc ratings. In North America, the most popular product options have an ATPV...

Will the LED headlamp on my faceshield or hood explode?

Will the LED headlamp on my faceshield or hood explode? Oberon promotes the use of LED headlamps on all arc flash faceshields and suit hoods to enhance the workers ability to properly see the work task. Oberon has performed limited testing of the products we support. The arc flash exposures were relevant to the protection provided by the arc flash PPE. During testing none of the LED lamps exploded and we observed no signs of concern regarding melting, dripping or continued...

Does Oberon offer a long coat type arc flash suit?

Does Oberon offer a long coat type arc flash suit? No, Oberon has been a strong advocate against the use of this type of arc flash suit for the past 20 years. Long Coat with leggings style arc flash suits are a protection concern for workers! If a worker doesn't kneel or squat with their legs together a large opening is created at the bottom. Furthermore, thermal incident energy can deflect and chimney up inside the long coat. Arc flash suits...
