The IEEE 1584 arc flash boundary equations can also be used to calculate the arc flash boundaries with boundary energy other than 1.2 cal/cm^2 such as onset to 2nd degree burn energy. Those conducting flash hazard analyses must consider this boundary, and then must determine what PPE should be worn within the flash protection boundary.

More openness for arc flash suit hoods. New definition of arc flash suit includes the hood to allow for balaclava/goggle assemblies. The definition is 360-degree protection so the company has freedom to choose the best system for all hazards. The committee stopped short of recommending these systems when using the HRC tables.

There are two primary uses for flame resistant fabrics: flash fire and arc flash. Full scale flash fire tests pre-date arc flash testing but the arc flash market has grown much faster, primarily due to work practice and hazard assessment standards which are all but absent in the flash fire exposure workplace.

I am getting inquiries about the need for name tags on shirts to be FR or not. My answer is always that nothing flammable should be exposed, per the standards. My feeling however is that a 3" x 2" tag will likely not cause death or serious injury by itself. Opinions please. Thanks

The main change is the title to include "flame resistant" AND arc flash. There are some materials which claim flame resistance but have negative effects in arc flash. ASTM F1506 and ASTM F1891 eliminate these types of materials by requiring a design arc test.

[email protected] [email protected] Abstract – A test program was completed to measure arc flash incident energy from actual 480-V utility equipment to determine the most appropriate flame resistant clothing for utility workers. The equipment tested included self-contained and CT-rated meters, padmounted transformer

A combination of an arc-rated T-shirt and overshirt was used for the testing. In one arc exposure, the T-shirt was dry, and it was wet in the second exposure. The mannequin used in the test was nonconductive, but a tracking arc under the overshirt took place in both cases. The dry T-shirt received more arc char damage than the wet shirt.
