A basic uniform of 8cal/cm^2 ensures clothing will not melt or continue to burn after arc extinguishes. Requiring employees to change clothes affects productivity and will lead to compliance mistakes.

This week's question is about a misunderstanding regarding the arc flash hazard. 1.2 cal/cm2 is the commonly referenced incident energy level where arc rated PPE is required. Because of this value, some have stated that an arc flash hazard does not exist below this value - I've seen this on labels in the past.

Below is a short piece that I wrote a few months ago on the subject which leads us to this week's question.

No Arc Flash Hazard Article?

Do you/employees wear arc rated PPE below incident energy levels of 1.2 cal/cm2?
Yes
No
It Depends
N/A
