Panic Bar
A crash bar (also known as a panic exit device, panic bar, or bump bar)American National Standards Institute, ANSI/BHMA A156.3-2001, American National Standard for Exit Devices is a type of door opening mechanism which allows users to open a door by pushing a bar. While originally conceived as a way to prevent crowd crushing in an emergency, crash bars are now used as the primary door opening mechanism in many commercial buildings. The device consists of a spring-loaded metal bar which is fixed horizontally to a door that swings in the direction of an exit. Depressing the bar unlatches the door, allowing occupants to quickly leave the building. Modern fire standards often mandate that doors be fitted with crash bars in commercial and other occupancies where mass evacuation may be slowed by other types of door openers. They are sometimes intended solely for emergency use and may be fitted with alarms. However, in many buildings the crash bar is the primary mechanism for openi ...

Scotland
Scotland is a Countries of the United Kingdom, country that is part of the United Kingdom. It contains nearly one-third of the United Kingdom's land area, consisting of the northern part of the island of Great Britain and more than 790 adjacent Islands of Scotland, islands, principally in the archipelagos of the Hebrides and the Northern Isles. To the south-east, Scotland has its Anglo-Scottish border, only land border, which is long and shared with England; the country is surrounded by the Atlantic Ocean to the north and west, the North Sea to the north-east and east, and the Irish Sea to the south. The population in 2022 was 5,439,842. Edinburgh is the capital and Glasgow is the most populous of the cities of Scotland. The Kingdom of Scotland emerged as an independent sovereign state in the 9th century. In 1603, James VI succeeded to the thrones of Kingdom of England, England and Kingdom of Ireland, Ireland, forming a personal union of the Union of the Crowns, three kingdo ...

Hex Key
A hex key (also, hex wrench, Allen key and Allen wrench, Unbrako or Inbus) is a simple driver for Bolt (fastener), bolts or screws that have heads with ''internal'' hexagonal recesses (Socket wrench, sockets). Hex keys are formed from a single piece of hard hexagonal steel rod, having blunt ends that fit snugly into similarly shaped screw sockets. The rods are bent to 90°, forming two arms of unequal length resembling an "L". The tool is usually held and twisted by its long arm, creating a relatively large torque at the tip of the short arm; it can also be held by its short arm to access screws in difficult-to-reach locations and to turn screws faster at the expense of torque. Hex keys are designated with a socket size and are manufactured with tight tolerances. As such, they are commonly sold in kits that include a variety of sizes. Key length typically increases with size but not necessarily proportionally so. Variants on this design have the short end inserted in a trans ...

Dog (engineering)
In engineering, a dog is a tool or part of a tool, such as a pawl, that prevents or imparts movement through physical engagement. It may hold another object in place by blocking it, clamping it, or otherwise obstructing its movement. Or it may couple various parts together so that they move in unison – the primary example of this being a flexible drive to mate two shafts in order to transmit torque. Some devices use dog clutches to lock together two spinning components. In a manual transmission, the dog clutches, or "dogs" lock the selected gear to the shaft it rotates on. Unless the dog is engaged, the gear will simply freewheel on the shaft. This word usage is a metaphor derived from the idea of a dog (animal) biting and holding on, the "dog" name derived from the basic idea of how a dog jaw locks on, by the movement of the jaw, or by the presence of many teeth. In engineering the "dog" device has some special engineering work when making it – it is not a simple part to make ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mortise Lock
A mortise lock (also spelled mortice lock in British English) is a lock that requires a pocket—the mortise—to be cut into the edge of the door or piece of furniture into which the lock is to be fitted. Mortise lock describes only a method of fitting the lock, and says nothing about the quality or key mechanism. In some parts of the world, mortise locks are found on older buildings constructed before the advent of bored cylindrical locks, but they have recently become more common in commercial and upmarket residential construction in the United States. The design is widely used in properties of all ages in Europe. History Mortise locks have been used as part of door hardware systems in the US since the second quarter of the eighteenth century. In these early forms, the mortise lock mechanism was combined with a pull to open the unlocked door. Eventually, pulls were replaced by knobs. Until the mid-nineteenth century, mortise locks were only used in the most formal rooms in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

International Building Code
The International Code Council (ICC), also known as the Code Council, is an American nonprofit standards organization sponsored by the building trades, which was founded in 1994 through the merger of three regional model code organizations in the American construction industry. Since 2023, ICC's headquarters has been based at Capitol Crossing in Washington, D.C. The organization creates the International Building Code (IBC) and International Residential Code (IRC), two model building codes, which have been adopted for use as a base code standard by most jurisdictions in the United States. The ICC's model codes have been criticized for inflating housing costs and reducing housing supply in the United States through arbitrary and stringent standards that do little for safety and are out of sync with best practices in other countries. The IBC has contributed to the spread of 5-over-1 type of buildings across the US and contributed to a lack of medium-density housing (so-called ...

List Of Fatal Crowd Crushes
This is a list of crowd collapses and crushes in which at least five people died. The deadliest modern crowd crush incidents have both occurred during the Hajj pilgrimage, with the 1990 Mecca tunnel tragedy claiming 1,426 lives and the 2015 Mina stampede claiming 2,400. (Although the term "stampede" is used in some media outlets, the scientific consensus is that true stampedes involving humans are extremely rare.) Ancient era *In AD 80, the Roman-Jewish historian Josephus recorded that in Jerusalem, while Ventidius Cumanus was procurator of Judea (AD 48–52), a Roman soldier mooned Jewish pilgrims at the Jewish Temple in Jerusalem who had gathered for Passover, and "spake such words as you might expect upon such a posture", causing a riot in which youths threw stones at the soldiers, who then called in reinforcements. The pilgrims panicked, and the ensuing stampede reportedly resulted in the deaths of thousands of Jews. According to Josephus, "upwards of ten thousand" a ...

Human Crush
Crowd collapses and crowd crushes are catastrophic incidents that can occur when a body of people becomes dangerously overcrowded. When numbers are up to about five people per square meter, the environment may feel cramped but manageable; when numbers reach between eight and ten people per square meter, individuals become pressed against each other and may be swept along against their will by the motion of the crowd. Under these conditions, the crowd may undergo a progressive collapse where the pressure pushes people off their feet, resulting in people being trampled or crushed by the weight of other people falling on top of them. At even higher densities, the pressure on each individual can cause them to be crushed or asphyxiated while still upright. Such incidents are invariably the product of organizational failures, and most major crowd disasters could have been prevented by simple crowd management strategies. Such incidents can occur at large gatherings such as sporting, co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Exit
An emergency exit in a building or other structure is a special exit used during emergencies such as Structure fire, fires. The combined use of regular and emergency exits allows for faster Emergency evacuation, evacuation, and emergency exits provide alternative means of evacuation if regular exits are inaccessible. Emergency exits must: * Be clearly marked (usually with signage that is normally illuminated, or is illuminated by a backup power source if central power fails) * Be in easily-accessible locations * Direct people to safe areas (usually outside) * Be regularly maintained and free of obstructions (they may not be used for storage) * Be secured to prevent unauthorized entry during normal operations An emergency exit's path usually ends in an outward-opening door with a crash bar with exit signs pointing to it. It is usually a door to an area outside of the building, but may also lead to an adjoining, fire-isolated structure with clear exits of its own. A fire esca ...

Building Code
A building code (also building control or building regulations) is a set of rules that specify the standards for construction objects such as buildings and non-building structures. Buildings must conform to the code to obtain planning permission, usually from a local council. The main purpose of building codes is to protect public health, safety and general welfare as they relate to the construction and occupancy of buildings and for example, the building codes in many countries require engineers to consider the effects of soil liquefaction in the design of new buildings. The building code becomes law of a particular jurisdiction when formally enacted by the appropriate governmental or private authority. Building codes are generally intended to be applied by architects, engineers, interior designers, constructors and regulators but are also used for various purposes by safety inspectors, environmental scientists, real estate developers, subcontractors, manufacturers of b ...
