Definition

The occupational exposure limit value indicates, „up to which concentration of a substance acute or chronic harmful effects on health are generally not to be expected.“ It replaced the previously applied MAK values (values for the maximum workplace concentration) on January 1, 2005.

Evaluation and publication of occupational exposure limits

Legally binding values are defined by the Committee on Hazardous Substances (AGS) according to the criteria of BekGS 901 „Criteria for the derivation of occupational exposure limits“ were developed or evaluated and published in the TRSG 900 announced.

The following are used for the evaluation MAK values the German Research Foundation and the Occupational exposure limits of the EU.

If no occupational exposure limit values are specified for a substance in the TRSG 900, the TRSG 402 be used for the evaluation.

Occupational exposure limits in agitator technology

Occupational exposure limits can also play a role in agitator technology. When stirring powders, for example, fine mists can be whirled up by the stirring process. Powder particles can also be released into the air when powders are added to and stirred into liquids. Some substances release vapors into their surroundings during stirring.

We support you in complying with the occupational exposure limits. To this end, we supply you with suitable lids for safely sealing the agitator application with an extraction unit mounted directly on the lid. Extraction above the application is also possible.
