Poison Prevention

Did you know? Most poisonings occur in children less than 6 years of age, yet most poisonings are both predictable and preventable.


Safety Tips

  • Actively supervise young children
  • Keep all poisons locked up and out of sight and reach of young children, this includes: medicines and herbal products, household cleaners, plants, antifreeze and windshield washer fluid
  • Install carbon monoxide alarms according to the manufacturer’s instructions
  • Keep the number of the nearest Poison Centre nearby and stored it in your cell phone1
  • Teach children the hazard symbols and what they mean2

Medicine Safety

Medicines are the leading source of poisoning for children. Most poisonings occur in the home. Always keep medication locked up and out of sight and reach of children .

Safe Use

  • Do not take your medicine in front of your children as they often imitate others. Medicine can look like candy.
  • Never share medicine with others, or use someone else’s medicine.
  • Take medicine as directed. Read instructions carefully.
  • Check the expiry dates. Ask your pharmacist if you are not sure when the medicine expires.
  • Never refer to medicine as candy. Medicine that is flavoured will be very appealing to children. Use extra caution with these types of medicines.

Safe Storage

  • Lock up all medicine, including those for pets.
  • Safety lids on medicine bottles are NOT childproof. Do not depend on safety lids to keep children protected.
  • Keep medicine in its original container.
  • Medicine should not be kept in your purse or diaper bag.
  • Do not keep your medicine in the bathroom. Heat and moisture could spoil it.
  • Refrigerate medicine only if it says to do so on the label.
  • When visitors come to your home, make sure they keep their bags or purses out of reach.
