Direct guidance
What to know or do
Request an occupational assessment of the specific room and procedure. Odour is not a reliable exposure measure, and a mask intended for infection control does not replace gas capture and ventilation.
What changes the answer
- The named chemical, biological, radiation, physical or scheduling hazard
- How often and how much exposure occurs, including spills and take-home residue
- Engineering controls, task changes and correctly fitted PPE available at work

When to get individual help
Contact your doctor or maternity service promptly and describe the timing, severity, associated symptoms and pregnancy week so they can choose the right assessment.
