Gun safes were designed
for the storage of guns and ammunition in domestic conditions.
Usually they don't provide any sufficient qualities, such as anti-break
and fire-resistant properties. The most logical way would be to
call them "metal boxes". But in the case of the fire
they still can defend people from the explosion and guns they
contain from unauthorized access.
Strong fastening of a gun safe is the obligatory
option, because due to its specific construction when unlocked
it can fall. It is interesting that among gun safes a lot of built-in
safes can be met.
