Occupational hygiene for airborne chemicals and other materials has mainly
focused on the world as it is rather than how it might be changed. We have
described as scientifically as possible workers' exposure and its determinants,
and the effectiveness of control equipment and control strategies. This has led
to a long string of good tools such as occupational exposure limits, sampling
strategies and devices, check-lists, product information sheets, communication
to employers and employed, and more cost-effective control equipment. All these
tools have been continuously sharpened, and we have seen a very significant
lowering of the exposure in the past 3040 years.
In an article, published recently in the "Annals of Occupational Hygiene Volume
50"the authors have looked much less at the production processes and the ways
that materials are handled, and how these affect exposure. It is easy to say
why. Production management is usually unwilling to let us make experimental
changes with a process, so we must use good model experiments.
