Quick Answer
Ensure proper ventilation without compromising safety by using a space heater with adequate ventilation, opening windows for cross-drafts, or creating a makeshift ventilation system using a fan and a heat-resistant material.
Creating a Ventilation System
When stranded in a vehicle in snowy conditions, a reliable ventilation system is crucial to prevent carbon monoxide buildup. One effective method involves using a portable fan to circulate air while keeping the vehicle’s windows slightly ajar. Position the fan 6-8 feet away from the vehicle to ensure the exhaust from the fan doesn’t re-enter the vehicle.
Alternative Ventilation Methods
In the absence of a portable fan, create a makeshift ventilation system using a heat-resistant material such as a metal sheet or a heat-resistant plastic sheet. Attach the material to the vehicle’s hood or a nearby surface and use a makeshift downdraft to direct cold air into the vehicle. Ensure the downdraft is positioned at least 10 feet away from the vehicle to prevent cold air from entering through the windows.
Space Heater Safety
When using a space heater, ensure it is at least 3 feet away from any flammable materials, including clothing, bedding, or nearby objects. Install a carbon monoxide detector in the vehicle to alert occupants of potential CO buildup. Maintain a consistent ventilation system while operating the space heater to prevent CO accumulation.
