  3. Use separate storage areas to isolate workers from hazardous substances.
  4. Ventilate storage areas separately from the rest of the workplace.
  5. Train workers thoroughly in handling and safety procedures.
  6. Wear personal protection equipment such as gloves, goggles and respirators.
  7. Monitor the workplace regularly using appropriate equipment to track the amount of hazardous substance in the air or environment.
  8. Consult with workers regularly to maintain and improve safety and handling practices.

 

Written records

If using hazardous substances in the workplace, you must maintain certain records, including:

  1. Risk assessment details
