Safety (firearms)

In firearms, a safety or safety catch is a mechanism used to help prevent the accidental discharge of a firearm, helping to ensure safer handling.

Safeties can generally be divided into subtypes such as internal safeties (which typically do not receive input from the user) and external safeties (which typically allow the user to give input, for example, toggling a lever from "on" to "off" or something similar). Sometimes these are called "passive" and "active" safeties (or "automatic" and "manual"), respectively.

Firearms with the ability to allow the user to select various fire modes may have separate switches for safety and for mode selection (e.g. Thompson submachine gun) or may have the safety integrated with the mode selector as a fire selector with positions from safe to semi-automatic to full-automatic fire (e.g. M16).

Some firearms manufactured after the late 1990s include mandatory integral locking mechanisms that must be deactivated by a unique key before the gun can be fired. These integral locking mechanisms are intended as child-safety devices during unattended storage of the firearm—not as safety mechanisms while carrying. Other devices in this category are trigger locks, bore locks, and gun safes.

Safety

Safety is the state of being "safe" (from French sauf), the condition of being protected against physical, social, spiritual, financial, political, emotional, occupational, psychological, educational, or other types or consequences of failure, damage, error, accidents, harm, or any other event that could be considered non-desirable. Safety can also be defined to be the control of recognized hazards to achieve an acceptable level of risk. This can take the form of being protected from the event or from exposure to something that causes health or economical losses. It can include protection of people or of possessions.

Meanings

There are two slightly different meanings of safety. For example, home safety may indicate a building's ability to protect against external harm events (such as weather, home invasion, etc.), or may indicate that its internal installations (such as appliances, stairs, etc.) are safe (not dangerous or harmful) for its inhabitants.

Discussions of safety often include mention of related terms. Security is such a term. With time the definitions between these two have often become interchanged, equated, and frequently appear juxtaposed in the same sentence. Readers unfortunately are left to conclude whether they comprise a redundancy. This confuses the uniqueness that should be reserved for each by itself. When seen as unique, as we intend here, each term will assume its rightful place in influencing and being influenced by the other.

Safety (gridiron football score)

In gridiron football, the safety (American football) or safety touch (Canadian football) is a scoring play that results in two points being awarded to the scoring team. Safeties can be scored in a number of ways, such as when a ballcarrier is tackled in his own end zone or when a foul is committed by the offense in their own end zone. After a safety is scored in American football, the ball is kicked off to the team that scored the safety from the 20-yard line; in Canadian football, the scoring team also has the options of taking control of the ball at their own 35-yard line or kicking the ball off themselves. The ability of the scoring team to receive the ball through a kickoff differs from the touchdown and field goal, which require the scoring team to kick the ball off to the scored upon team. Despite being of relatively low point value, safeties can have a significant impact on the result of games, and Brian Burke of Advanced NFL Stats estimated that safeties have a greater abstract value than field goals, despite being worth a point less, due to the field position and reclaimed possession gained off the safety kick.

Firearm

A firearm is a portable gun, being a barreled weapon that launches one or more projectiles often driven by the action of an explosive force. The first primitive firearms were invented in 13th century China when the one-person-portable fire lance was combined with projectiles. The technology gradually spread through the rest of East Asia, South Asia, Middle East and then into Europe. In older firearms, the propellant was typically black powder, but modern firearms use smokeless powder or other propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stability.

Modern firearms are usually described by their caliber (i.e. their bore diameter, this is given in millimeters or inches e.g. 7.5mm, .357) or in the case of shotguns their gauge (e.g. 12 ga.); the type of action employed (muzzle, breech, lever, bolt, pump, revolver, semi-automatic, automatic etc.) together with the usual means of deportment (hand-held or mechanical mounting). They may be further distinguished by reference to the type of barrel used (rifled) and the barrel length (19 inch), the design's primary intended use (e.g. hunting rifle), or the commonly accepted name for a particular variation (e.g. Gatling gun). The word firearms usually is used in a sense restricted to small arms (weapons that can be carried by a single person), whereas the word artillery covers larger gunpowder-fired weapons.

Firearms (video game)

Firearms, sometimes referred to as FA or Firearms Half-Life, was a multiplayer mod for the first-person shooter video game Half-Life. Initially developed in 1998-2000 from a Quake mod, Firearms was created as a quasi-realistic team-based first-person shooter. The mod has been noted for its wide range of weaponry, innovative game modes, immersive sound and realistic weapons handling.

A continued evolution of the game, Firearms: Source, was later developed for the Source engine.

History

The current, and final build is Release Candidate (RC) 3.0 which was released on April 18, 2005. FA was originally created by Caspar Milan Nielsen and Brian Fuller. Versions 2.0 through (RC) 2.5 were developed under the leadership and programming of Eric Smith (Zerk). Firearms 2.4 was included in the Counter-Strike retail package and was later awarded PC Gamer's Mod of the Year award and PC Gamer's Best Multiplayer Game of the Year Runner-up in the year 2000. Firearms was at one time the #3 most popular mod based on the Half-life engine, after Counter-Strike and Team Fortress Classic. Later versions, (RC) 2.6 through (RC) 3.0 were developed under the direction of Ben Irwin.
