First you have to dig your car out and unless luck is on your side, you’re likely to be digging out a new parking spot when you arrive at your destination.

But it isn’t just about the hassle of digging out.

The McGill University Health Centre (MUHC) issued a statement Saturday, reminding the population of the risk of carbon monoxide poisoning after heavy snowfalls.

THE MUHC recommends adhering to the following safety tips: 

• Remove the snow from your car prior to starting the engine.
• Ensure the exhaust pipe is not blocked.
• Do not leave children alone in an idling car.
• Never leave your car running inside the garage even if the garage door is open.

Clearing the exhaust pipe is especially important after a large snowfall. An exhaust pipe blocked by snow and idling can produce carbon monoxide poisoning inside the car leading to death.

The MUHC also warned that the effects of carbon monoxide poisoning can occur before you are even aware you’ve been exposed to the toxic gas.

Carbon monoxide is odourless, colourless and tasteless and can be hazardous even at low levels of exposure.

Signs and symptoms of carbon monoxide poisoning:

• Mild poisoning can cause headaches, dizziness, nausea, vomiting and fatigue.
• More serious exposure can result in fainting, convulsions, coma and even death.

Pregnant women and their foetuses, as well as young children and the elderly are more at risk, according the MUHC.
