Quick Answer
When building an igloo, it's essential to light it safely to avoid fires spreading and to reduce the risk of carbon monoxide poisoning. This can be achieved by following specific best practices for using a lantern, stove, or fire. Proper ventilation and positioning of the flame can help prevent ignition of the igloo's snow walls.
Choosing the Right Lighting Source
When selecting a lighting source for your igloo, consider a portable lantern or a small camping stove with a windscreen. A lantern is a safer option as it produces less heat and doesn’t have an open flame, reducing the risk of igniting the surrounding snow. If you choose a stove, make sure it has a built-in safety feature such as a flame arrestor or a spark arrestor to prevent sparks from igniting nearby snow.
Lighting and Ventilation
When lighting your lantern or stove, always position it at least 3 feet away from the snow walls to prevent accidental ignition. Ensure good ventilation by opening a window or creating a small gap in the door to allow stale air to escape. This will also help to prevent carbon monoxide buildup. Aim the flame or light source upwards to minimize the risk of melting snow and to prevent heat from radiating towards the walls.
Precautions and Maintenance
Before lighting your lantern or stove, inspect the igloo’s structure to ensure it’s stable and secure. Avoid using open flames near the igloo’s entrance, as this can melt snow and compromise the structure’s integrity. Regularly inspect your lantern or stove for damage or wear and tear, and maintain them according to the manufacturer’s instructions. Finally, always follow local regulations and guidelines for using open flames in enclosed spaces.
