What Should You Know About Igloo Emergency Situations?

Building a Safe Igloo Structure

When building an igloo, start by selecting a site with a flat surface, ideally on a snow slope to allow for a stable foundation. Look for a location with minimal wind direction and proximity to a water source. Gather blocks of snow that are large enough to be used as building blocks, ideally 1-2 meters in diameter and weighing around 10-20 kilograms. Use a shovel to shape the blocks and create a stable base for your igloo. Begin stacking the blocks in a spiral pattern, overlapping them to create a sturdy structure. The ideal igloo should have a dome shape, with a base diameter of around 2-3 meters and a height of 1.5-2 meters.

Staying Warm Inside the Igloo

To stay warm inside the igloo, it’s essential to maintain a good airflow system. Create a ventilation hole at the top of the dome to allow for airflow and prevent carbon dioxide buildup. Use a candle or a small fire to warm up the air inside the igloo before sealing it with snow blocks. This will help to prevent moisture from accumulating and reduce the risk of hypothermia. A well-insulated igloo can maintain a temperature of around 10-15°C (50-59°F) inside, even in extreme cold weather.

Common Hazards to Avoid

Common hazards to avoid when building an igloo include crevasses, avalanches, and hypothermia. When building, be aware of your surroundings and watch for signs of unstable snow. Use a probe to check the depth of the snow and avoid building near areas prone to avalanches. Inside the igloo, avoid excessive physical activity and keep your head and neck covered to prevent heat loss. Stay hydrated by drinking plenty of water and avoid overexerting yourself.
