極寒

極度の寒さにおいては、低体温症、凍傷、スリップ、転倒、一酸化炭素中毒のリスクが高まり、死亡の可能性もあります。誰でも冬季の天候によって心身に影響を受けることがありますので、自分や家族そして地域の安全を守るためにも、しっかり準備をして必要なことをしてください。

冬季の天候における健康上の問題

冬季の天候がつづく間は、低体温症、凍傷、スリップ、転倒、一酸化炭素中毒のリスクが高まり、死亡の可能性もあります。冬の天気が心身へ影響することは誰にでもありえますので、そのための備えをして必要な対策をしてください。

スリップと転倒

雪や氷の季節には屋外で滑って転倒する危険性が高まります。この時期には、救急外来を訪れたり、滑って転倒して入院する人が増えることもあります。年齢や能力に関係なく、誰にでも転倒のリスクがあります。転倒は適切なツールと準備によって防ぐことができます。  

スリップと転倒を避けるヒント

  • • 目的地まで十分な時間を持てるように、事前に計画を立てる。
  • • 地面に氷や雪がある場合は、整備された歩道を歩く。
  • • 厚いノンスリップトレッドソール(滑らず歩ける靴底)を備えた、よくフィットしたブーツか靴を履く。
  • • バランスを取るため、杖やスキーポール、ウォーキングステッキなどを使う。杖を使用する場合は、先端に伸縮式のアイスピックを取り付ける。
  • • 滑りやすい路面では、(ペンギンのように)つま先をわずかに外側に向けて短くすり足で歩く。詳細については、この 冬のウォーキングビデオ をご覧ください。

一酸化炭素(CO)中毒

冬の間は、暖房装置によってはスペースを暖めるために燃料を燃やすため、それにより一酸化炭素中毒が発生する頻度が増えます(たとえばガス暖房、薪、石炭ストーブ、石油、灯油)。一酸化炭素中毒は、過度に一酸化炭素を吸い込むと発症し、装置が誤作動したり、あるいは換気が不十分なスペース(たとえば煙突が塞がれていた、窓が閉まったまま、テント内など)で使用した場合に生じます。一酸化炭素は目に見えず匂いも味もないですが、数分で生死にかかわる可能性を有しています。

  • At home

    • Heat your home to at least 21℃ if infants or elderly people are present. During winter months, heating costs may increase. If you have difficulty paying for heat, consider exploring BC Hydro’s Energy Conservation Assistance Program and check if your city or town has a rent bank.  
    • Make a plan and prepare your home for winter hazards in your area. See the PreparedBC Guides for Winter Weather and Storms, Power Outages, Floods, Avalanches and other BC hazards.  
    • Build an emergency kit and restock it after each use. See the PreparedBC Home Preparedness Guide. 
    • Maintain public spaces outside of your home, including sidewalks and parking areas, as safe pathways for everyone's mobility. 
      • Learn snow shovelling tips to prevent injuries.  
      • Some communities have Snow Angels / Snow Stars programs to assist seniors or people with disabilities to clear snow off walkways. This can decrease injury risk and support people's mobility. Volunteers are always needed! Contact your local government or First Nation for more information.   
    • During winter, carbon monoxide poisoning may occur more frequently as some heating systems burn fuel to keep spaces warm (e.g. gas heating, wood or charcoal stoves, oil, kerosene). Carbon monoxide poisoning occurs when people inhale too much carbon monoxide and can happen when appliances malfunction or are used in spaces without adequate ventilation (e.g., blocked chimneys, closed windows, or inside a tent). You cannot see, smell or taste carbon monoxide, but it can be deadly in minutes.

  • Getting around outside

    • Check the weather report before going outside. Plan a safe route with extra time to navigate winter conditions.  
    • Dress for winter weather:  
      • Wear layers, preferably with a waterproof or windproof outer layer. Take off layers as you heat up to avoid sweating. The risk of hypothermia increases when you or your clothes are wet. 
      • Choose wool or synthetic clothing, which keeps people warmer and dryer than cotton.  
      • Depending on the temperature and wind (wind chill), exposed skin can freeze in minutes. Wear a hat, scarf, mittens or gloves.    
      • Use boots or shoes that fit well, are insulated, waterproof, and have good traction. Consider wearing traction devices on footwear, but remember that they can be slippery on smooth surfaces like tiles.  
      • Wear bright and reflective clothing so vehicles can see you in the dark. Drivers should proceed cautiously, and visibility can increase safety for people walking, rolling or biking.  
  • Avoiding slips and falls

    • Plan ahead so you have enough time to get where you're going.
    • Walk on cleared walkways if there is ice and snow on the ground.
    • Use boots or shoes that fit well and have a thick, non-slip tread sole.
    • Use a cane, ski poles or walking sticks to help with balance. If using a cane, attach a retractable ice pick to the end.
    • Take short shuffling steps with your toes pointed slightly outward on slippery surfaces (like a penguin). Watch this winter walking video for more tips.
  • Driving

  • During winter storms and extreme cold

    • Check weather advisories from Environment and Climate Change Canada and emergency alerts from Emergency Info BC. 
    • Contact your Local Government or First Nation for community support.  
    • Know where to go for the right healthcare during winter months.  
    • Consider rescheduling activities or limiting time outdoors during colder temperatures. 
    • Check-in on your neighbours, friends and family, especially older adults or people with disabilities who live alone. Make sure they are keeping warm and check if they need supplies, transportation, assistance clearing snow or other support.     

Local weather, shelter, and emergency information

During winter weather events, local governments, First Nations, and non-governmental organizations in the Vancouver Coastal Health (VCH) region operate shelters or encourage people to use other public spaces (like libraries and community centres) to safely warm up and avoid exposure to the cold. Some spaces are open overnight, and others are available during the day. More spaces may be added during a weather alert, when risk increases due to cold, wind and/or precipitation.  

Many local governments and First Nations post updated information on their social media pages about warming centres or temporary shelters activated during winter weather warnings. 

Shelter options may change quickly based on the current weather conditions and capacity. Confirm with organizations directly if services or spaces are currently available.
