I assume that is the manufacturer MSDS? Sigma-Aldrich has a very thorough MSDS databse. I do most of my MSDS research on their site if I can.

If you enter the CAS number from the above MSDS/PDF (65997-17-3) into the Sigma-Aldrich database you come up with "Glass Spheres" - physical appearance "fibers". IARC Class 2A - Probably Carcinogenic to Humans. It is listed as a Carcinogen according to OSHA. It is also listed as a Mutagen.

Open the link and click on "Download MSDS (PDF)"

Any kinda dust is bad in your lungs.Unfortunately I work in dusty conditions all the time and I can't wear a respirator all the time.

Despite the CAS number being for Fiberglass wool, the datasheet is for **SILICA** spheres (There is concern over the potential carcinogenicity of respirable SILICA and other refractory fibres).

HOWEVER

Glass fibres are NOT silica fibres and do not present the same hazards. On the same site is a MSDS for glass wool:

Counter to the insinuation in your post, the manufacturer is probably the best source of information:

PPG:

OCF:

Yes, I work(ed) for a glass company (neither of the above) in an OHS role - It irks me that mis-information and conspiracy theories propagate more readily than scientific fact: Glass fibres are not considered carcinogenic. The main hazard of working with them is 'nuisance dust' causing skin & respitatory tract irritation.

But wear a good dust mask, anyway.

I've breathed plenty of fiberglass particles.Carcinaginec or not I wouldn't recomend it.
