Hi, ..I see reports on people stuck in snow in places like New Mexico. One thing is getting stuck in snow on the road, there you "just" need watch out for tail pipe gases killing you, you either wanna stop in some wind blown place, where the snow and tail pipe gases are blown away, or combine the snow and your car into an "igloo." And you don't want your "igloo" chewed up by some snow thrower. And you will need fresh air in your "igloo", or, the snow thrower won't matter. ;o) ..need water? Melt some snow. ..in some house, motel, or airport terminal etc building? Make sure the people owning or running etc the joint, understands the snow loads on the roof. Collapse risk. ..dry fresh snow is lightweight, and only of concern if the roof has not been designed to carry it. Weigh it. ..wet snow can easily approach a ton per cubic meter, that's one meter deep snow on one square meter or "one meter each way", or 35 cubic feet, as in "over 3 feet deep on 11 square feet." ..2 meters or 6 feet? If you're in a nuclear blast shelter, "no big deal," for any other kinda structure, you wanna check or remove the snow, or even evacuate people. ..snow load checks are easy, use a yard stick or somesuch and probe the depth, either "on the lawn" or on the roof, then put some snow in a box and weigh it, say on a bath room scale. ..divide that weight by the box volume, and you have the snow density, should be in the 0.15 to 1 metric tonne per cubic meter range or 9 thru 63lb per cubic feet. Multiply that by your roof size and your probed snow depth, and you have your snow load. ..e.g: 25kg/(44cm*12in*250mm) (25*kilogram)/(44*centimeter*(12*inch)*(250*millimeter)) = approx. 745.64543(kg/m^3) <> convert lb/ft^3 745.64543(kg/m^3) = approx. 46.549124(lb/ft^3) <> 46.549124lb/ft^3*12m*8m*40in ((46.549124*pound)/(foot^3))*(12*meter)*(8*meter)*(40*inch) = approx. 160.33619klb <> convert ton 160.33619klb = approx. 72.727273t ..if you anywhere near doubt your roof can take those "extra" 73 tons, evacuate all the people under it, then remove those 73 tons of snow.
