[Determination and occupational health evaluation of pollutant concentrations from combustion engines in occupational...

For ensuring compliance with the maximum working place concentration values MAKD and MAKK for the use of internal combustion engines in workrooms, new directives for the determination of pollutant emissions, the calculation of working place concentrations, and the industrial-hygienic assessment are now available in form of the completely revised version of the national standard TGL 33,358/01 to 03 which is mandatory as from August 1st, 1988. Here, contrary to the former methodology pursuant to TGL 32,610/02, a partly additive, partly individual assessment of the pollutants is made. The inclusion of further emission sources in the industrial-hygienic assessment is envisaged. For the projecting stage, a mathematical estimation model has been developed which considers such requirements as air exchange and duration of use of the internal combustion engines already in the planning stage. Practice-orientated examples are given to facilitate the application of this directive for control bodies of industrial-hygiene, projectors, and other users.
