Fire Sprinklers
A fire sprinkler or sprinkler head is the component of a fire sprinkler system that discharges water when the effects of a fire have been detected, such as when a predetermined temperature has been exceeded. Fire sprinklers are extensively used worldwide, with over 40 million sprinkler heads fitted each year. In buildings protected by properly designed and maintained fire sprinklers, over 99% of fires were controlled by fire sprinklers alone

Fire Hydrants, Hoses,...
Fire Hydrants, Hoses, Etc.
The user (most likely a fire department) attaches a hose to the fire hydrant, then opens a valve on the hydrant to provide a powerful flow of water, on the order of 350 kilopascals (51 psi); this pressure varies according to region and depends on various factors (including the size and location of the attached water main). This user can attach this hose to a fire engine, which can use a powerful pump to boost the water pressure and possibly split it into multiple streams. One may connect the hose with a threaded connection, instantaneous "quick connector" or a Storz connector.[4]
If a fire hydrant is opened or closed too quickly, a water hammer can occur and damage nearby pipes and equipment. The water inside a charged hose line causes it to be very heavy, and high-water pressure causes it to be stiff and unable to make a tight turn while pressurized. When a fire hydrant is unobstructed, this is not a problem, as there is enough room to adequately position the hose.[clarification needed]
Most fire hydrant valves are not designed to throttle the water flow; they are designed to be operated full-on or full-off. The valving arrangement of most dry-barrel hydrants is for the drain valve to be open at anything other than full operation. Usage at partial opening can consequently result in considerable flow directly into the soil surrounding the hydrant, which, over time, can cause severe scouring. Gate or butterfly valves can be installed directly onto the hydrant opening to control individual outputs and allow for changing equipment connections without turning off the flow to other outlets. These valves can be up to 12 inches (30 cm) in diameter to accommodate the large central "steamer" outlets on many US hydrants. It is good practice to install valves on all outlets before using a hydrant as the protective caps are unreliable and can cause major injury if they fail.
