When to open your windows for ventilation in a snowstorm?

Ventilation Protocol

When stranded in a snowstorm with a running engine, open your windows for 30 minutes every hour. This will help to remove stale air and prevent carbon monoxide buildup. To minimize heat loss, crack the windows instead of fully opening them. A 2-3 inch opening is sufficient for ventilation.

Carbon Monoxide Risks

Carbon monoxide is a colorless, odorless gas that can be deadly in high concentrations. Engine exhaust fumes contain high levels of carbon monoxide, which can accumulate inside a vehicle, especially when the engine is running for an extended period. Symptoms of carbon monoxide poisoning include headaches, dizziness, and nausea.

Ventilation Timing

Timing is crucial when ventilating a vehicle during a snowstorm. Open your windows as soon as the engine is running, and maintain a consistent ventilation schedule. It’s also essential to keep the vehicle’s engine in a well-ventilated area, away from doors and windows to prevent fumes from entering the vehicle.
