I was reading about glass on the Point Blanks/Patagonia site and came across this… Fiberglass: The main ingredient in fiberglass is sand. The glass fibers are treated with various finishes so they absorb and bond well with the different resins. For instance, Volan® Cloth uses Chromium, an environmental and health hazard, as one of the finish elements, which is why we dont use it.

Volan is cooked at a lower temperature. it isn’t supposed to be sanded into, how much of a hazard is it, worse than driving a car to work?

What`s even more shocking is that laboratory rats got sick and died when they consumed large quantities of Chromium coated Volan® Cloth. Will the horror never end?

I guess the problem is in the manufacturing rather then for the builder/end user. If it gets out into nature and our food change it’s all our problem. http://www.atsdr.cdc.gov/tfacts7.html have some facts. I clipped this from http://www.oshaslc.gov/dts/sltc/methods/inorganic/id215/id215.html 1.8.3. Workers handling liquids or solids containing Cr(VI) compounds have developed skin ulcers. 1.8.4. Certain Cr(VI) compounds (calcium chromate, chromium trioxide, lead chromate, sodium dichromate, strontium chromate, and zinc chromate) are known animal and/or human carcinogens. The International Agency for Research on Cancer (IARC) has determined that Cr(VI) is carcinogenic to humans (Group 1), based on sufficient evidence in humans for the carcinogenicity of Cr(VI) compounds as found in chromate production, chromate pigment production, and chromium plating industries (5.17). IARC’s determination is also based on sufficient evidence in experimental animals for the carcinogenicity of calcium chromate, zinc chromate, strontium chromate, and lead chromate; and limited evidence in experimental animals for the carcinogenicity of chromic acid and sodium dichromate. I don’t know what kind of compound is used on volan or what the real risk is but a little more information would be nice. regards, Håvard
wait a second, fiberglass is bad for you? oh no i guess i better start wearing a mask huh? haha
