Prevention and control of chemical exposures in the rubber manufacturing industry in the Netherlands

In a survey in the rubber manufacturing industry in The Netherlands both the chemical and physical exposure of operators as well as company policies on working conditions were assessed. Defining the effectiveness of control measures was a part of this study and is the subject of this article. A method of solution-directed workplace analysis was applied to compare and evaluate the control measures within this branch of industry. Elimination of sources appears to be a strategy for prevention which has been adopted on only a limited scale. Control of exposure to particulates is more frequently applied, with local exhaust ventilation as the most important control measure. Both qualitative and quantitative analysis confirmed that local exhaust ventilation has a limited effect. Dust-free forms of chemicals, especially those with health risks, are used on only a moderate scale. In addition to hazard identification and evaluation based on exposure levels, the foreseeable risks associated with the design and requirements of production processes were established. The forthcoming industrial agreement for the rubber manufacturing industry in The Netherlands will, amongst other measures, stimulate use of source related strategies.
