Debbi:
You need to start with defining a PPE Program and a plan for procurement. For example what do you need for arc rated PPE, level system, with everyday wear first and layering, or second level as a specific arc flash suit? You should develop a document outlining what you need for electrical specific PPE.
After this what is your procurement strategy, three bids and a buy, or from the local supplier (if there is one).
Do I have any concerns with respect to inherent or chemical treated fabric? Both are perfectly accepteable and meet the applicable Standards. No issues.
After all of this work (there are other details you should review), then you should talk to the the fabric manufacturer, make sure they are credible, have the technical information you need. I say this as the distributor/retailer may not have the information you need. Most distributors/retailers are not knowledgeable in Canada yet about NFPA 70E and CSA Z462. You may have to buy from out of Province if you can't find a reputable supplier in the Province you are from.
Anyways you can see there is a process here... Feel free to contact me I live in Calgary, and my business partner is in Ontario, ESPS Electrical Safety Program Solutions INC. is a Canadian consulting services company for electrical safety, audit, electrical safety programs (for example defining an electrical specific PPE program) and training.
