Legal Restrictions

Restrictions according to § 5 of the "Mutterschutzrichtlinienverordnung":

  • Pregnant women must not work with carcinogenic, reproductive toxic or mutagenic compounds. Working with fatal or toxic compounds or with compounds which may cause chronic diseases is only allowed within the limit values. Pregnant women may work with carcinogenic, reproductive toxic or mutagenic compounds, if they are not exposed to them. An exposure has to be assumed even if anybody else in the same room is opening a bottle with a relevant compound.
  • Nursing mothers may work with carcinogenic, reproductive toxic, mutagenic, fatal or toxic compounds or with compounds which may cause chronic diseases only within the limit values.
  • Women of reproductive age may work with compounds containing lead or mercury alkyls only within the limit values.

Limit values:

  • Occupational exposure limit (air concentration) according to TRGS 900.
  • Biological limit value (generally concentration in blood or urine) according to TRGS 903.

According to § 4 of the "Mutterschutzrichtlinienverordnung" the empoyer has to prevent pregnant or nursing women from any risk. It is well known that conditions which are risk-free for "everybody" sometimes may not be applied for pregnant women (think of "contergan"). Therefore you will find in the TRGS 900 a column with code letters where "Y" means that for pregnant women there is still a risk even within the limit values and "Z" means that the risk does not change for pregnant women. If there are no data (legal restrictions, limit values) it is the job of the employer to evaluate the risk.
