Quick Answer
A trench shelter is the most common type of shelter for sandstorm safety due to its effectiveness in blocking wind and sand. It's relatively easy to dig and can be made anywhere. This type of shelter can be built in a matter of minutes.
Building a Trench Shelter
When building a trench shelter, choose a location that provides protection from the wind direction. Dig a trench that is at least 1 meter deep and 1 meter wide, with a slope of about 30 degrees to prevent sand from accumulating at the bottom. The trench should be long enough to fit all people seeking shelter, with a width of about 2-3 people per meter.
Sand Blocking Techniques
To prevent sand from entering the trench, use a combination of methods. First, line the bottom and sides of the trench with a layer of rocks or sandbags. Then, use a combination of sandbags or small rocks to block the entrance and any gaps along the sides. Finally, cover the top of the trench with a layer of sandbags or a tarp to prevent sand from falling in.
Staying Safe Inside the Shelter
Once inside the trench shelter, stay away from the entrance and any gaps along the sides to prevent sand from entering. Use a space blanket or a tarp to cover yourself and stay warm. Avoid breathing in sand or dust, which can cause respiratory problems. Stay in the shelter until the sandstorm passes, and the air is safe to breathe again.
