Quick Answer
When using tree wells for emergency shelters, common mistakes include not considering snow load, inadequate snow removal, and poor tree selection, which can compromise the structure's integrity and lead to accidents.
Insufficient Snow Load Consideration
When building a shelter in a tree well, it’s essential to consider the weight of the snow that will accumulate on the structure. Tree wells can be prone to deep snow, which can cause the snow load to exceed the weight-bearing capacity of the trees. To mitigate this risk, look for areas with a shallow snowpack or use additional support structures to distribute the weight more evenly.
Inadequate Snow Removal Techniques
When removing snow from the tree well, use techniques that minimize the risk of collapse. Avoid piling snow against the trees, as this can cause added weight and pressure on the structure. Instead, shovel snow away from the area in a controlled manner, creating a clear path for access and egress. Use a slope of at least 30 degrees to prevent snow from accumulating and compromising the structure.
Poor Tree Selection
Not all trees are suitable for supporting emergency shelters in tree wells. Avoid trees with signs of decay, cracks, or splits, as these can compromise the structural integrity of the shelter. Opt for trees with a diameter of at least 12 inches, and ensure that the area is free of any hazards such as dead branches or standing water.
