Hot Suit

[shaw0486]

Hi,
I need to purchase a hot suit for arc flash. Can anyone recommend anything? Also what cal rating should i purchase. We work on 480 volts @ 1200 amps max I would say for this exercise.

Thanks,

You need to get some training on arc flash, first.

Basically, both the NEC and NFPA70E define a Qualified Worker as one who understands the hazards and knows how to select the appropriate PPE.

Although I agree with Jim on his intent I would add that not everyone is required to or follows NFPA70E. What Jim is saying more or less is that there is much more involved than just buying a suit, although using any suit may be better than nothing, the correct suit is what you should be wearing.

as stated, there is more to it than buying a suit, unless you want to buy a suit to meet the most stringent requirements even though it may not be needed. every situation will be different.

Having done studies for many years, I have very rarely encounted service entrance locations that did not have PPE requirements of >40 cal/cm?. Many, if not most, people consider this level to be beyond their 'live work' cut-off point.

However, most 'service shops' eventually find the occasion to use "Category 4 PPE" rated for a minimum of 40cal/cm?.

Like the other guys said you need training, even asking this question shows you do not understand arc flash hazards. Whar you should really buy is a lock out set and stop doing energized work.

What Zog said. Hire a professional who does this type of work daily. At least two professionals

particpate here at MH Forum.

But you still need PPE suitable for the hazard to verify the lockout.

Yep, hence the training, shouldn't be doing any of this without the training required to be a "Qualified person"

people keep saying this, but if the numbers come up > 40, how do you even safely verify the lockout?

You have to install something to reduce the incident energy, or open the circuit at a point where the incident energy is less. Often the incident energy on the primary (high voltage) side is much less.

or get an 80 cal suit
