Glass fibres are much less dangerous than asbestos for two reasons. Firstly, being non-crystalline, they do not tend to break as easily into very small bits, and secondly, glass is slightly soluble in bodily fluids, which means small particles usually dissolve rather than remaining as an irritant. And also, silicates (which glass is) are not generally carcinogenic. Most non-urban dust is composed mainly of silicates. On the other hand, as anyone who has used the stuff knows, glass fibres are definitely a skin irritant!
