Direct guidance

What to know or do

Stop for dizziness, faintness, headache, confusion, racing heartbeat or very little urination. Severe symptoms need urgent assessment.

What changes the answer

  • The exact product, task, temperature, duration and ventilation
  • Whether exposure is through breathing, swallowing, skin contact or injury
  • Any label warning, spill, symptoms or repeated occupational-level exposure

Check the exact item or situation with a doctor, midwife, pharmacist or relevant clinician; the name of a broad category is not enough for a personal decision.
