Empty and damaged containers
- An empty plastic, glass or metal container that held a Class A, B or C pesticide must be promptly triple-rinsed or jet-rinsed with clean water or another suitable solvent.
- A container counts as empty when less than 2.5 cm of material remains in the bottom.
- Rinse water goes into the spray tank for use, or is disposed of as waste under the Environmental Protection Act.
- Rinsed containers go to a pesticide container depot for recycling or are disposed of under the waste rules.
- Rinsing is not required for refillable containers returned to the vendor, aerosol cans, containers the label says not to rinse, or where the Director agrees it is impractical.
- Paper or cardboard containers may be burned only where by-laws allow, keeping smoke away from people, animals, buildings and roads, or disposed of as waste.
- If an original container is damaged, clean up spillage and decontaminate under the registrant's direction, transfer the product to an equivalent labelled container and treat the broken container as empty.
Water, spills and theft
