Biological agent tolerance value

from Wikipedia, the free encyclopedia

The biological agent tolerance value (BAT value) is a limit value for the concentration of an agent, its metabolites or a stress indicator in the biological material (e.g. blood or urine ) of an employee. It is assumed that if the limit value is complied with, the health of an employee is generally not impaired, even after repeated or long-term exposure . BAT values ​​apply to individual substances and only to people who are healthy and of working age.

In Germany, BAT values ​​are set by the permanent Senate Commission for the testing of harmful substances from the German Research Foundation and in Switzerland by the Swiss Accident Insurance Fund (Suva). The biological working substance tolerance value should not be confused with the biological work place tolerance value, for which the abbreviation "BAT value" is also used. The biological workplace tolerance value was a legally relevant limit value of the Hazardous Substances Ordinance in Germany until January 1, 2005 .

Germany

A list of maximum workplace concentrations and biological substance tolerance values ​​is published annually by the permanent Senate Commission for the testing of harmful substances from the German Research Foundation (DFG). According to TRGS 903, the recommendations of the Senate Commission for biological substance tolerance values ​​are checked by the Committee for Hazardous Substances (AGS) and, if necessary, adopted as biological limit values (BGW).

According to the occupational health rule (AMR) 6.2 " Biomonitoring ", the biological substance tolerance values ​​of the DFG may be used to assess biomonitoring findings that were collected from an employee as part of the preventive occupational health care .

Switzerland

Since 1994, Suva has been setting biological tolerance values ​​for working substances in Switzerland and publishes them annually in the publication "Grenzwerte am Arbeit". In accordance with the ordinance of the Federal Council on the Prevention of Accidents and Occupational Diseases (VUV), preventive occupational health care for employees in Switzerland is carried out by Suva's occupational medicine department in collaboration with practicing doctors and company doctors. Occupational exposure to a chemical agent can be assessed with the help of indoor air measurements in the breathing zone or by means of biological monitoring (biomonitoring): In biological monitoring, the value measured in the biological material of an employee is compared with the BAT value for the agent compared.

In Switzerland, BAT values ​​are assigned for carcinogenic substances (additional classification C1 and C2).
