Extreme heat: heat stress can cause dizziness, nausea, headache and, in severe cases, heat stroke. Watch for symptoms and move to a cool place if you feel unwell. Southwestern Public Health issues heat warnings when daytime temperatures reach 31°C or higher for 2 or more days. During a heat warning, we may open a cooling space at the Joe Thornton Community Centre (75 Caso Crossing, 519-633-7112). The INN (10 Princess Avenue, 519-637-9898) and Ignite Youth Centre (745 Talbot Street, 519-631-8820) also offer cooling spaces.
Extreme cold: unprotected skin can freeze in under 30 minutes at -15°C. Watch for frostbite and hypothermia symptoms, and dress in layers. Southwestern Public Health issues cold alerts at -15°C, or -20°C with wind chill. We open a warming space at the Joe Thornton Community Centre during cold alerts, 8 a.m. to 10 p.m. The INN offers 24-hour overnight shelter.
Tornado: know the difference between a tornado watch (conditions are favourable) and a tornado warning (a tornado has been reported or is imminent). Take shelter in the lowest, most central room of your home, away from windows. If outdoors, lie flat in a low area and cover your head. Never shelter under an overpass.
Freezing rain and ice storms: watch for falling branches and downed power lines, and avoid driving until roads are treated.
Snowstorms and blizzards: stay indoors if possible. If your vehicle gets stuck, stay inside, crack a window for fresh air, and run your engine for about 10 minutes every half hour if the exhaust isn't blocked.
Fire or explosion: install smoke and carbon monoxide alarms, and practice your escape plan. If there's a fire, sound the alarm, evacuate immediately, and call 911. If you can't leave, stay low, cover your nose and mouth, and signal for help from a window.
Hazardous material spills: do not attempt cleanup if you don't know the material or lack protective equipment. Evacuate the area and call 911 for large spills. For chemical releases, follow instructions from emergency responders, who may direct you to shelter in place or evacuate.
Windstorms: seek shelter indoors, away from windows and large open spans like gymnasiums, when winds reach 60 to 65 km/h or gust above 90 km/h.
Human health emergencies: stock non-perishable food and medication for at least 2 weeks, and make a plan for dependents and pets in case you become ill. Wash your hands often, cover coughs and sneezes, and stay home if you're sick.
Drinking water advisories: Southwestern Public Health issues advisories when water testing shows a problem. A boil water advisory means bacteria may be present, and boiling kills it. A "do not drink" advisory means chemical contamination that boiling cannot fix. A "do not use" advisory means the water is unsafe for any use, including skin contact.
