非政府系団体のためのVCHの高温時の安全確認サポートの枠組み
Heat check-ins happen in a variety of settings and by staff or volunteers with diverse training. Given the wide context, this framework was created so organizations may select the information that is most relevant to their setting to develop their own organizational check-in plans.
高温時の安全確認サポートの枠組みをダウンロードSteps to protect yourself and others from heat
The most dangerous aspect of heat waves for most people is high indoor temperatures. Spending time in a cool space and drinking plenty of water is the best way to prevent heat-related illnesses.
Wildfire smoke can also cause health problems. During both wildfire smoke and heat events, consider also filtering your air using HEPA air cleaners. Find out more about wildfire smoke.
-
Keep yourself and other people cool
- Spend time in cooler indoor and outdoor spaces (i.e. community center, library or mall with air conditioning).
- Drink plenty of water and other liquids to stay hydrated, even if you do not feel thirsty.
- Cool off with a shower, bath or soaking part of your body in water.
- Wear a wet shirt or damp towels to cool down.
- Wear loose, light-coloured, breathable clothing.
- Limit activity, especially during the hottest hours of the day (generally 2 p.m. to 4 p.m. in B.C.).
- Watch for signs of heat exhaustion and heat stroke. For heat-vulnerable people, the risk for heat-related illness may increase at indoor temperatures over 26°C (78 °F) and may be very high at indoor temperatures over 31°C (88 °F).
-
Keep spaces cool
- During the day, close windows and shades/blinds to trap cooler air inside and block the sun.
- At night, open windows and doors when it is cooler outside (usually 9-10 p.m. in B.C.). Some bathroom and kitchen fans vent outside and can be used to remove warmer indoor air. Use portable fans to bring cool air into the home overnight.
- Consider getting an air conditioner for your home. If you have air conditioning, be sure to turn it on.
- Monitor indoor temperatures for yourself and those you are checking on. For heat-vulnerable people, the risk for heat-related illness may increase at indoor temperatures over 26°C (78 °F).
“Heat Warnings” and “Extreme Heat Emergencies”
In response to the 2021 BC heat dome, multiple health sector partners, and Environment and Climate Change Canada (ECCC) developed the BC Heat Alert and Response System (BC HARS). This two-level alert system lays out the criteria that ECCC will use to declare a Heat Warning (Level 1) or an Extreme Heat Emergency (Level 2), the appropriate public health messaging for both types of alerts, and the recommended actions for the health sector, local governments, and other partners.
Read more about the BC HARS on the BCCDC website.
Alerts
-
Heat Warning (Level 1)
Threat: Daytime and overnight temperatures are higher than seasonal norms and holding steady.
Action: Take the usual steps to stay cool and check on people at higher risk from heat. -
Extreme Heat Emergency (Level 2)
Threat: Daytime and overnight temperatures are higher than seasonal norms and getting hotter every day.
Action: Activate your emergency plan and check on people at higher risk from heat at least once a day.
Special considerations for mental health and substance use
For many, extreme weather can take a toll on mental health and well-being. Challenges with substance use can increase, and substance use can place people at high risk for heat-related illness. Don’t hesitate to get help when you need it. There are supports available.
