no. 20 lbs a square foot but can be up to 2.5 times that in static weight.   :shaka:

Pretty sure it's 20psf here for roofs.

40psf for residential flooring. Assuming the safe is roughly 4'x4' 20sqft -> 514lb safe + 100lb of firearms -> 38psf; should be okay in theory but you'd have to ask the builder/engineer.

Personally I'd just stick it on ground floor. If you have cheap tile it's probably Grade 3 so maybe put down plywood first. If slab shouldn't matter.
