It is the health effects that are chronic – ie they can creep up over a period of many 10s of years…
Until very recentely, the recognised thinking was that “one fibre can kill you”. HSE always took the line that a single exposure event could lead to chronic or fatal health effects much later on.
There is some ongoing debate about this, and that view might well be adjusted – but asbestos fibres do remain in the lung once inhaled, so over time even one fibre (or a similar small number) from a single or small number of exposure could result in a long term health impact.
The cigarette analogy is not appropriate for asbestos.
to dismiss it as “health and safety gone mad” is plainly stupid.
