Abstract |
Recommendations are made for the prevention of occupational disease due to mono- and dinitriles and cyanohydrins. The time-weighted average concentrations for up to a 10h workshift, 40h work week or ceiling concentrations based on a 15min sampling period are (mg/m3, ppm, type of limit given): acetonitrile (34, 10, TWA); propionitrile (14, 6, TWA); n-butyronitrile (22, 8, TWA); isobutyronitrile (22, 8, TWA); acetone cyanohydrin (4, 1, ceiling); glycolonitrile (5, 2, ceiling); malononitrile (8, 3, TWA); adiponitrile (18, 4, TWA); succinonitrile (20, 6, TWA); tetramethylsuccinonitrile (6, 1, ceiling). Other recommendations relate to medical surveillance, labelling and posting, personal protective equipment and clothing, information of personnel, work practices and control procedures, sanitation, monitoring and recordkeeping. The criteria on which the recommendations are based are discussed at some length under the following heads: biological effects (literature review, dose-response relations); environmental data; exposure control; development of standard; research needs. Procedures for sampling and analysis and first aid are given in appendices. |
