I work at a semi conductor facility & employees are required to wear clean room suits made of polyester blend over regular street cloths. The electricians are required to wear their flash suits over the clean room suits. Would this be acceptable since the clean room suits are a poly blend? If acceptable or not acceptable, can you advise where specifically this is stated. Thanks

Hello hello2U2,
I'm certainly no expert but I see some problems of logic here. First, you end up with three layers of clothing.
Second the purpose of polyester clean room costume would be to limit or contain cotton fibers.
Third the purpose of the arc flash clothes would be to lessen the burning caused by the melting of the plastic [polyester] fabric. By having the polyester inside next to your body, it would seem to be more dangerous. Furthermore, having the cotton arc fault clothing would allow the cotton fibers to migrate freely since they are not contained by the polyester layer.

Re: clean room suits & flash suits
I agree with Peter. Wearing the flash suit in a clean room environment completely negates the value of a clean room suit worn under it. Sounds like somebody who demands a "clean room suit at all times" doesn't understand what's going on.

Re: clean room suits & flash suits
When I have worked at Pharmaceutical companies the worry was not cotton fibers but bio-hazzards your body might bring into the clean rooms.
There where areas where I would literally have 3 layers of clean room suits over my street clothes, shoes.
I have no idea how a flash suit would figure into this, I imagine it would have to be under the clean room suits. That may be a problem with flash suit use.

Re: clean room suits & flash suits
seems to me it would make more sense to wear the clean room suit on the outside and wear the flash suit under it.
the whole purpose of the clean room attire is to reduce the risk of getting fibers from your clothing (including the flash suit) into the air inside the clean room.
I once heard that there is a flash suit made for this type of application that is none shedding. You might be able to subsititute it for the clean room attire and only have to wear one layer. I have no information on such a thing though. Just something I vaguely remember from the far reaches of my mind.

I would suggest contacting a PPE Manufacturer such as Salisbury. Wearing a polyster blend on the outside will assist in keeping the fire burning. The PPE is FR material to either prevent or self-extinguish if ingnited. Sounds like you have a rock and a hard place.
