A protocol for systematic workplace investigation in the rubber manufacturing industry.

A protocol for systematic workplace investigation in the Dutch rubber manufacturing
industry has been developed. The protocol, based on results and experiences of an industry-wide
hygiene study, makes it possible to evaluate and control hazardous working conditions in rubber
manufacturing facilities not included in the hygiene survey. Emphasis is placed on the assessment of
exposure to particulates, rubber fumes, solvents and noise, and of dermal exposure to contaminants,
but also of exposure to vibration, extreme climatic conditions, deleterious working postures, accident
risks and unhealthy working habits. Data are collected by using questionnaires and check-lists with
the analysis being performed using a large number of decision trees which are based on the best
technical means of controlling hazardous working conditions.
A test was carried out to compare the results of the protocol with results of the hygiene study and
although this test indicated that the protocol does not generate quantifiable results, it was concluded
that it could be a very useful tool for evaluating control measures, for indicating better means of
controlling hazardous working conditions and for setting priorities for exposure monitoring and
workplace improvement.
