The most common causes are accidents with grease guns, paint sprayers, and pressure washers, but working on diesel and gasoline engine fuel injection systems as well as pinhole leaks in pressurized hydraulic lines can also cause this injury. Additionally, there is at least one known case of deliberate self-injection with a grease gun. [2]
As with their air-actuated cousins, powder-actuated guns have a muzzle safety interlock. If the muzzle is not pressed against a surface with sufficient force, the firing pin is blocked and cannot reach the load to fire it. This helps ensure that the gun does not discharge in an unsafe manner, causing the nail to become an unrestrained projectile.
The vacuum draws liquid foam concentrate from a reservoir, which mixes with the water stream through a metering device on the discharge side of the eductor where a firefighting hose is connected. Typically the 200 psi inlet water pressure is reduced to 95 psi discharge pressure as a result of the narrowness of the venturi in the eductor device.
Due to the nature of the bladder, the stream produced is fairly constant, and has almost the same range and power throughout the entire shot, most streams dropping only one foot in range towards the end of a continuous shot, unlike most air pressure based water guns which exhibit a constant loss of pressure while the trigger is pulled.
A potato cannon, also known as a potato gun or potato launcher, is a pipe-based cannon that uses air pressure ... The air reservoir (3) is filled to 120 psi (0.83 MPa ...
The .277 Fury SAAMI (voluntary) MAP chamber pressure of 80,000 psi (551.6 MPa) enables a 135 grains (8.7 g) projectile muzzle velocity of 3,000 feet per second (914 m/s) from a 16-inch (406 mm) barrel. [1] [10] It also means that the .277 Fury is normally chambered in small arms that are capable of handling the accompanying bolt thrust safely.
The light-gas guns are typically divided into categories of single-stage and two-stage light gas gun. [1] One such single-stage light gas gun is located at Marquette University, Milwaukee, WI. It had been used for studying polymers and metals in pressure regions up to 20 GPa. The light gas gun at Marquette was manufactured by PAI and delivered ...
