If you use pesticides, know the rules to ensure your safety.
When using pesticides
- Always read and follow product label instructions and warnings. If it is unclear, ask your employer.
- Wear the appropriate personal protective equipment (PPE) specified on the product label. Report any problems with your PPE to your employer.
PPE is any piece of clothing or equipment used to protect you from exposure to pesticides.
Different pesticides may require different types of PPE as specified on the products labels. It can be as simple as chemical-resistant gloves, closed-toe footwear and long-sleeved shirt and long pants. It may also involve using a protective suit, eye protection, a mask or a respirator.
Your employer is responsible for ensuring that all pesticides used are approved for use in Canada, that label instructions are strictly followed, and that you have the necessary PPE that fits properly and allows you to work safely.
Tips
Do not
- Drink, eat, or smoke while applying pesticides;
- Rub your eyes or touch your mouth while working with pesticides;
Do
- Stay clean to protect yourself from pesticide exposure – Wash your hands immediately after applying pesticides and before eating, drinking, smoking, chewing gum or tobacco, or using the toilet; Shower at the end of the day and wash your clothes separately to prevent contamination.
After using pesticides
Stay out of areas where pesticides have been sprayed until you are told that it is safe to enter.
