Mutagenic substances

What is the risk?

Some substances (mutagens) may impair a woman’s ability to have children or may damage the unborn child. These substances do not affect young people any differently from adults.

How to avoid the risk

Exposure to these substances must be reduced to as low a level as is reasonably practicable. In carrying out the risk assessments, you should have regard for women who are pregnant, or who have recently given birth. Practical advice on protecting the health and safety of new or expectant mothers is given in HSE guidance.
