Occupational Health & Safety: Protect yourself when working in cold weather

The joys of living in Alberta. Press release from Work Safe Alberta.

Edmonton... With the cold temperatures in Alberta, workers and employers need to take extra steps to keep worksites safe.

Safety requirements for working in cold weather:

• Working outside in the cold can make workers vulnerable to frostbite and hypothermia, which can be fatal. Workers should dress in layers so that they can add insulation when not active.
• Layers can also be removed during heavy physical activity in order to prevent overheating and dehydration.
• Clothing should be loose so it does not restrict circulation.
• Clothing should be cleaned regularly or else it may not insulate well.
• Coffee and tea dehydrate the human body so water should also be drunk in order to keep fluid levels up.

Using space heaters in cold weather:

Using propane or kerosene heaters that are poorly ventilated can cause drowsiness, headaches and dizziness from reduced oxygen levels and build-up of carbon monoxide.

Safe ways to use space heaters:

• Allow a fresh air vent by opening a window or door. For example, when using a large 165,000 BTU propane or kerosene heater in a double car garage or equal sized building, the overhead door should be open at least four inches. For a single car garage, or equal sized space, the overhead door should be open at least seven inches.
• Follow the manufacturer's instructions to ensure safe use of the heating device.
• Consider using electric heaters in enclosed areas with limited ventilation.
