Direct guidance
What to know or do
Stay out of the work zone, prevent dust being tracked into living areas and use a qualified contractor where hazardous material is possible. Tell your care team about a substantial or repeated exposure.
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
General guidance
When to get individual help
Choose a lower-risk alternative when possible. If the exposure already happened, record the product, amount, timing and symptoms and ask for advice instead of assuming harm.
