Why does fire sprinkler water smell?
Slime-forming bacteria (iron-related bacteria that generate white, beige, grey, or black slime) Sulfate-reducing bacteria (which may turn water black and are responsible for much of discolored water’s smell in fire protection systems)
What are fire sprinklers made of?
Steel has traditionally been the material of choice for fire sprinklers, although thermoplastic pipes now dominate residential and other light-hazard categories.
Is fire sprinkler water safe?
Myth: Fact: “Water damage from a sprinkler system will be more extensive than fire damage.” Water damage from a building sprinkler system will be much less severe than the damage caused by water from fire fighting hose lines or smoke and fire damage if the fire is allowed to spread.
Is sprinkler water contaminated?
Irrigation pipes in lawns and gardens retain water long after the system has been turned off. This water can become stagnant, harboring bacteria and other microorganisms. In the event of back-siphonage, unsanitary contaminants can infect the potable water supply.
Is there mercury in fire sprinklers?
It is alcohol (no longer mercury) and it has been dyed red so that you can see its position. Actually, this is only the case for thermometers.
What triggers water sprinklers?
Fire sprinklers work because high heat triggers the sprinkler system. When a blaze ignites, the air directly above it heats rapidly. This hot air rises and spreads along the ceiling. When the liquid expands, it shatters its glass confines and the sprinkler head activates.
What is the red liquid in a sprinkler system?
A glass bulb type sprinkler head will spray water into the room if sufficient heat reaches the bulb and causes it to shatter. Sprinkler heads operate individually. Note the red liquid alcohol in the glass bulb.
How do you turn off a fire sprinkler system?
Get a phone and the number of your sprinkler system’s installation company. The company will tell you the location of the water valve that controls the sprinkler system in your home or business. Find that valve and turn it clockwise until it the sprinkler system turns off.
What is dry sprinkler system?
A dry pipe sprinkler system is one in which pipes are filled with pressurized air or nitrogen, rather than water. Located in a heated space, the dry-pipe valve prevents water from entering the pipe until a fire causes one or more sprinklers to operate. Once this happens, the air escapes and the dry pipe valve releases.
What is a wet pipe?
A wet pipe system is one in which water is constantly maintained within the sprinkler piping. When a sprinkler activates this water is immediately discharged onto the fire.
