Jul 21, 2014· So far, there are few data on the asbestos level in the outdoor environment. One Japanese work has reported asbestos fiber size distribution in about 100 samples collected from outdoor air analyzed by TEM. Results indicated a high proportion of SAF chrysotile (85–92% of chrysotile SAF and 71% of chrysotile fibers < 1 μm) .

The mine consisted of a number of stopes (tunnels) and a milling operation (crushing the host rock to extract asbestos fibre). The miners had to crawl in the hot dark stopes bent almost double, as many stopes were not more than a metre high, and choking with dust. Working conditions in the mill were even worse than the mine.

Insualting board is considered to be friable as the material can liberate asbestos fibres into the air much more easy than asbestos cement. In many cases most asbestos consultants will assess insulating board as a cement product, however asbestos insulating board is a much lower density than cement.

The drilling of asbestos cement sheeting can release asbestos fibres into the atmosphere so precautions must be taken to protect the drill operator and other persons from exposure to these fibres. A hand drill is preferred to a batterypowered drill because the quantity of fibres that can become airborne is significantly reduced if a hand drill is used.
