Safety cabinets with automatic door closing provide additional security. After a defined time interval, the cabinets close automatically, thus minimizing the exposure of the stored chemicals and reducing the risk of escaping hazardous vapors. In modern safety cabinets, a visual and acoustic warning signal is given when the door is closed. [5]
A vision panel is a small window in a door which allows people to look through without opening the door. Vision panels are sometimes in walls, generally adjacent to a door. These have implications in safety, primarily to avoid opening doors on a person coming the other way, but also in case of fire to avoid opening a door onto a fire.
Requirements for earthquake (seismic code), hurricane, flood, and tsunami resistance, especially in disaster prone areas or for very large buildings where a failure would be catastrophic [citation needed] Requirements for specific building uses (for example, storage of flammable substances, or housing a large number of people)
Typical test standards for walls and floors are BS 476: Part 22: 1987, BS EN 1364-1: 1999 & BS EN 1364-2: 1999 or ASTM E119. [2] Smaller components such as fire dampers, fire doors, etc., follow suit in the main intentions of the basic standard for walls and floors.
When installed in a kitchen on standard (U.S) wall-mounted base unit cabinets, countertops are typically about 25–26 inches (640–660 millimetres) from front to back and are designed with a slight overhang on the front (leading) edge.

In most climates it is often better to have a vapor-open building assembly, meaning that walls and roofs should be designed to dry: [6] either to the inside, the outside, or both, so the ventilation of water vapor should be taken into consideration. A vapor barrier on the warm side of the envelope must be combined with a venting path on the ...
