Watch on YouTube

What happens here

The instructor reveals that there are four main categories of arc flash. A visual chart is presented, illustrating each PPE category (1-4) and its corresponding minimum arc rating in calories per square centimeter (cal/cm²), which represents the potential thermal energy release during an arc flash incident. This visual aid clarifies the escalating risk associated with higher categories.

Goal: Learn the four arc flash categories and their associated calorie ratings.

How many categories of Art Flash are there? Uh I don't know, four. Four categories. Most of the time, 99% of the time, our small company will deal with category one and category 2. Category 2 would be when we work in the distribution center when we work with 480 volt energized panels. We have the potential of a certain amount of calorie, right, that could come out, certain amount of energy. So, we need certain clothing that could protect us.
