The Baker cellar pipe consists of a smoothbore, straight stream nozzle on the end of a brass pipe 36-inches long or more that can be remotely angled from the floor above by firefighters to direct the stream to the desired cellar location. Charged line Fire hose under pressure from the pump at the engine. CFA 3-thread
Intermediate metal conduit (IMC) is a steel tubing heavier than EMT but lighter than RMC. It may be threaded. Electrical metallic tubing (EMT), sometimes called thin-wall, is commonly used instead of galvanized rigid conduit (GRC), as it is less costly and lighter than GRC. EMT itself is not threaded, but can be used with threaded fittings that ...
Small-hole gauge set. Sizes from top to bottom: 3 to 5 mm (0.118 to 0.197 in) 5 to 7.5 mm (0.197 to 0.295 in) 7.5 to 10 mm (0.295 to 0.394 in) 10 to 13 mm (0.394 to 0.512 in) Small-hole gauges require a slightly different technique to the telescopic gauges, the small hole gauge is initially set smaller than the bore to be measured.
Safety harnesses have restraints that prevent the wearer from falling from a height. By wearing the belt or harness the risk of injury from a fall is greatly reduced. The harness allows the user to attach themselves to an object that is stationary, ensuring they will not hit the ground in the event of a possible fall.

One of the most common ways to produce such threaded holes is to drill a hole of appropriate size with a drill bit and then tap it with a tap. Each standard size of female screw thread has one or several corresponding drill bit sizes that are within the range of appropriate size—slightly larger than the minor diameter of the mating male ...
An emergency medical technician (often, more simply, EMT) is a medical professional that provides emergency medical services. [1] [2] EMTs are most commonly found serving on ambulances and in fire departments in the US and Canada, as full-time and some part-time departments require their firefighters to at least be EMT certified.
Orifice plate showing vena contracta. An orifice plate is a thin plate with a hole in it, which is usually placed in a pipe. When a fluid (whether liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice [1] but as the fluid is forced to converge to pass through the hole, the velocity increases and the fluid pressure decreases.
