View full description

The Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area (MAK Commission) provides scientific policy advice to the German government on reducing human health hazards from chemicals. The MAK Commission proposes maximum workplace concentrations (MAK values) for volatile chemicals and dusts, biological tolerance values (BAT values), biologische Leitwerte (BLW), biological reference values for workplace substances (BAR) and analytical methods for substances in the air and biological material. Substances which are carcinogenic, germ cell mutagenic, sensitising or absorbed percutaneously or which pose a risk during pregnancy are classified accordingly. The latter classifications are the ones referenced here.

On 1 July of every year the proposals for maximum workplace concentrations (MAK values), biological tolerance values (BAT values) and classifications are published in the annual List of MAK and BAT Values and sent to the German Federal Minister of Labour and Social Affairs. The MAK and BAT data, proposed classifications and associated documentation are put up for public discussion six months before publication. The Ministry's Committee on Hazardous Substances (AGS) reviews the proposals and recommends adoption in the Hazardous Substances Ordinance.

Each year detailed documentation is published in German and English for all proposed MAK values, BAT values and classifications. These documents run to over 1000 printed pages.and are available available free of charge in electronic format online in German and English. It includes the documentation for the MAK and BAT values and the analytical methods for air and biological material.
