A safe (also called a strongbox or coffer) is a secure lockable box used for securing valuable objects against theft and/or damage from fire. A safe is usually a hollow cuboid or cylinder, with one face being removable or hinged to form a door. The body and door may be cast from metal(such as steel) or formed out of plastic through blow molding.
Bank teller safes typically are secured to the counter, have a slit opening for dropping valuables into the safe without opening it, and a time-delay combination lock to foil robbers/and or thieves. One Significant distinction between types of safes is whether the safe is secured to a wall or structure or if it can be moved around. A less secure version (only suitable for petty cash) is usually called a cash-box.
Specifications for safes include some or all of the following parameters: Burglar-resistance Fire-resistance Environmental resistance (e.g., to water or dust)Type of lock (e.g., combination, key, time lock, electronic locking)Location (e.g., wall safe, floor safe) Smart safes as part of an automated cash handling system 1 Room-sized fireproof vaults For larger volumes of heat-sensitive materials, a modular room-sized vault is much more economical than purchasing and storing many fire rated safes.
2 Fire-resistant safes A fire-resistant safe is a type of safe that is designed to protect its contents from high temperatures or actual fire. Fire resistant safes are usually rated by the amount of time they can withstand the extreme temperatures a fire produces, while not exceeding a set internal temperature, e.g., less than 350 °F (177 °C). Models are typically available between half-hour and four-hour durations. 3 Wall safes Wall safes are designed to provide hidden protection for documents and miscellaneous valuables. Adjustable depth allows the maximization of usable space when installed in different wall thicknesses. Some wall safes feature pry resistant recessed doors with concealed hinges for anti-theft protection. A painting can be hung over a wall safe to hide it from public view. 4 Jewelry safes Jewelry safes are burglary and fire safes made specifically to house jewelry and valuables. These high end safes are typically manufactured with interior jewelry chests of fine woods and fabric liners with a range of organizational configurations. 5 Safe-cracking Safe cracking is opening a safe without a combination or key. There are many methods to safe cracking ranging from brute force methods to guessing the combination. The easiest method that can be used on many safes is safe bouncing, which involves hitting the safe on top this may cause the locking pin to budge, opening the safe.
