[Do the isocyanate monomer standards still protect against attacks of occupational asthma? Should a standard including polyisocyanates be evolved?].

Field surveys of diisocyanates at the workplaces in Switzerland and particularly in car repair shops, where HDI was the most used, showed that the monomer levels comply with the Swiss permissible exposure limit (PEL) in the great number of situations. Cases of medical surveillance associated with industrial hygiene measurements demonstrate that occupational asthma was also observed in situations where the monomer concentrations are low although high peaks of prepolymers are often recorded. From the statistical data on compensations, the annual incidence of occupational asthma over the period 1988 to 1992 remains around 54 cases with a mean cost of 21,000 sFr. per case per year. It is suggested that a PEL on the prepolymers should be introduced in the Swiss PEL list to enhance the efficiency of prevention policy.

Analysis methods for new work cell standards. Risk analysis and risk reduction help in dealing with the revised Robot Standard.

The final reiterative loop of risk reduction leads to residual risk, sometimes called "tolerable risk." This is the risk with which one must live, and is typically handled through proper training, signage and personnel protective clothing. Any existing safeguards should be considered removed when performing a risk analysis. This will allow the full impact of the resulting tolerable risk (initial risk--risk reduction) to be more accurately evaluated. Trying to walk the fine line between the cost of making machine processes safe and the economics of staying competitive is not easy, and it is not the intent of the regulatory bodies to put companies out of business. However, a good rule of thumb with respect to OSHA is that if a machine process can be guarded, guard it. Otherwise the ultimate test of residual risk may be in the litigation.
