Calgary Fire urges awareness

Calgary Fire Department spokesperson Carol Henke says when shovelling snow around a home, it's important to remember to move it away from the fresh air intake so that carbon monoxide doesn't build up inside. It's also vital to have working carbon monoxide alarms, she said.

Firefightersresponded to multiple "monoxide-related incidents" the fire departmentsaid in a later statement Tuesday.

"If you are exposed to CO gas, you may get flu-like symptoms such as headaches, nausea and dizziness, as well as become confused, tired and lose consciousness," the statement read.

"If you or anyone in your house experiences the symptoms of CO poisoning or your CO alarm goes off, you should leave your residence and call 9-1-1. Do not go back into the house until the Fire Department tells you it is safe to do so."

In the morning while the snow was still falling, Environment Canada said motorists should consider postponing non-essential travel.

At around 8 a.m.,RCMP warned motorists to avoid travel on Highway 40 in Kananaskis Country west of Calgary.

"Road conditions are extremely poor due to accumulating snow and poor visibility," a release said.

Shortly after that, Canmore RCMP also advisedagainst non-essentialtravelon Highway 1 west from Exit 114 to the Banff Park gates, saying road conditions are poor with single-lane traffic in both directions as road crews work on clearing drifting and blowing snow.
