Containers, spills and disposal: key rules to remember

Our summary of what the official handbook says on this topic, in our own words. Read it before or after the practice questions above, then check the original chapter. Read the official chapter ↗

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

  • When using water from a well or surface water, take measures to prevent backflow of pesticide into the source.
  • Do not wash equipment in or near a well or body of water in a way that could discharge pesticide into it.
  • Immediately notify the ministry's Spills Action Centre if a fire or other occurrence may discharge pesticide into the environment in a harmful way.
  • Notify the Spills Action Centre as soon as practicable if any pesticide is stolen or otherwise leaves your control.
