| Resumen |
Recommendations are made for the prevention of adverse effects of nitrogen oxides on the health and safety of workers. The nitrogen dioxide ceiling concentration should not exceed 1ppm by volume (1.8mg/m3) as determined by sampling time of 15min and the time-weighted average exposure (10-h working day) to nitric oxide should not exceed 25ppm (30mg/m3) over a 40-h week. Other recommendations relate to medical supervision, labelling, personal protection, information of employees, work practices, monitoring and record keeping. The criteria on which the recommendations are based are discussed at some length under the following heads: biological effects of exposure; environmental data; development of a standard; compatibility with ambient air quality standards. Procedures for sampling and analysis of the oxides in air are described in detail and useful additional information (research needs; determination of exposure areas with detector tubes and direct reading instruments; recommendation for an identification data sheet for shipments; properties; tabulated data on nitrogen oxide release by oxyacetylene torches, on animal experiments, and on human exposure experiments; etc.) is given in appendices. |
