Mr. Giovanni,

If I properly understand your question I think your answer lies in research related to the vendor of your equipment. The manufactures of coupon cutters, wet saws with abrasive wheels and chop saws, all are going to suggest very specific consumable cutoff wheels for each task. The recommended wheels should come with an MSDS <Material Data Safety Sheet>, which will supply vital information related to toxicity, ventilation/fume extraction needs and sometimes data as specific as cartridge types for respirators. Most manufactures sell there own wheels or have a definite preference as to whose product they most trust on their equipment. I bet your equipment vendor has already done the homework you require. If not find a vendor of similar products that does substantial business in your area and they will have the data. If that data becomes prerequisite for a sale, the numbers will be forthcoming, you can bet on that!

The moral of the story is to put the burden on the vendor prior to purchase, thereby instilling a proper sense of urgency upon the correct party while having ALL of your needs met by somebody motivated to please you.

Here is a link which contains several OSHA case studies which you may find of interest

This site gave me a headache, but within lies some pretty specific language for Clean Air related to the Aerospace industry in the US including contact phone numbers of related divisions http://envinfo.com/caain/mact/aerofrul.html


These Guys make saws and wheels and I have found them to be helpful and easy to work with.
