Arrow BulletHot Weather Guidelines: Schools

Peel Health recommends the following steps to be taken to prevent heat related illness:

General Recommendations

  1. Establish a policy and plan to deal with extreme temperatures.

  2. When outdoors, stay in the shade whenever possible (natural or artificial structures). Especially limit time outdoors when temperatures and UV radiation are most intense, between 11 a.m. and 4 p.m.

  3. Monitor daily heat advisories and adjust outdoor activity schedules if possible.

  4. When in the sun, wear a wide brimmed hat, UV protective sunglasses, and loose-fitting long shirts and pants.

  5. As much as possible, ensure indoor temperatures are comfortable.

  6. Ensure children are well hydrated. Plain water is the liquid of choice, diluted fruit juice is okay.

  7. Monitor children in wheelchairs and check the temperature of metal and vinyl parts.

  8. Check the temperature of metal and plastic playground equipment.

  9. Staff should be aware of signs and symptoms of heat cramps, heat exhaustion, and heat stroke. Follow first aid procedures promptly.

  10. Staff should role model appropriate heat and sun safety behaviours.

  11. Apply sunscreen (SPF 15 or higher), 20-30 minutes before going outside to ensure absorption.

  13. NEVER leave children in a closed parked vehicle.
