Cash, jewellery, passports, deeds, medicines, keys, drives and paper records do not fail in the same way. Burglary resistance, fire protection, humidity control, capacity and access control must be chosen around the actual contents.
A fire safe is not automatically a high-security cash safe. A burglary-rated safe is not automatically suitable for paper records, backup drives, tapes or removable media during a long fire and cooling period.
Freestanding, wall, floor and underfloor safes all rely on surrounding structure, lifting route, fixing quality, concealment and future service access. The same rated safe can perform poorly in the wrong location.
