Where is theTamper in Sprinkler system?
The Tamper switches for a fire sprinkler system are located on the main control valves which are located on either side of the backflow preventer for a wet type automatic fire sprinkler system. These switches are wired into the monitoring control system/alarm panel to ensure the valves remain open at all times (or not tampered with.) If the tamper switches are used they will show a supervisory trouble on the panel so the monitoring company or business will know there system is out of service.
What are some examples of extra hazard occupancies per NFPA 13?
As Churches , clubs, hospitals offices, restrunt Library, institutional, museum resedential,and Educational
What is the liquid in a frangible - bulb fire sprinkler?
The glass bulb inside a fire sprinkler head is filled with a heat sensitive liquid (e.g., glycerine) that expands faster than the glass bulb as it gets hotter. Eventually, it expands so much that it causes the glass bulb to burst, releasing the water behind it.
The different colors of liquid contained within the bulb correlate to the temperature at which the sprinkler head will activate:
- Orange - 135oF
- Red - 155oF
- Yellow - 174oF
- Green - 200oF
- Blue - 286oF
- Purple - 360oF
- Black - 440OF
Different colors are used in different environments depending on the average ambient heat in said environment. For instance, if you have a storage facility that needs to be kept at temperatures higher than 135 F, you can imagine why you wouldn't want a orange-bulbed fire sprinkler!
What is the minimum distance allowed between a flammable storage cabinet and a radio?
The minimum distance between flammable material & radio depends the amount of radiation of radio. The flammable things may be wood because the cabinet is wood.
What the function of water flow switch in fire sprinkler system?
The function of a water flow switch is to detect water flow in the sprinkler system, usually during a fire event, to signal a local electrical fire alarm, or fire alarm panel to activate the alarm devices in the building,and send an alarm signal to a central station or alarm company to alert the fire department.
Why do soda acid fire extinguishers not put out oil fires?
Most of the contents of soda-acid extinguishers (which are obsolete and completely illegal in the USA) is water. Water and oil don't mix well. The water may actually spread an oil fire as the flaming oil expands across the surface of the newly created puddle of water or as the oil is splashed in all directions by the force of the spray.
Soda-acid extinguishers can also be hazardous to operate even to fight the type of fire they were designed to fight (wood or paper fires) due to the fact that they contain a jar of sulphuric acid. As the user must invert the extinguisher first to dump the sulphuric acid into the sodium bicarbonate solution in the body of the extinguisher there is a chance that if something is wrong with the extinguisher or the user holds the nozzle wrong at that moment, he might get sulphuric acid on his skin or clothes!
What is preaction sprinkler system?
A sprinkler system employing automatic sprinklers that are attached to a piping system that contains air that might or might not be under pressure, with a supplemental detection system installed in the same areas as the sprinklers.
Preaction systems are typically installed in areas where water damage due to accidental discharge of the sprinklers or breakage of the piping is a concern, or damage in the sprinklers and piping due to freezing. There are three types of preaction systems: non-interlock,single interlock, and double interlock.
non interlock: water flow to sprinklers upon fused sprinkler or detection
single interlock: water flow upon detection
Double interlock: water flow only when detection and sprinklers detect fire
NFPA 1002 is the Standard for Driver Operator Professional Qualifications.
How can sprinkler heads get damaged?
its just water running out of the pipes from the valves. it happens when the heads are lower than the valves. even if the valve is off, the water left in the pipe still runs downhill. like water running out of a hose that isn't connected. If its happening all the time your valve may be leaking, and that should be fixed.
Can you start your own fire department?
Theoretically - yes. However - your 'powers of arrest' are limited to those of any ordinary citizen.
Another View: Actually -- no, you cannot. It is realized that the word 'police' is commonly misused and misunderstood by the general public to refer to any uniformed force carrying out enforcement-type functions. However, the fact is that only the government retains "police" powers and you cannot assume "police"powers on yourself. You can certainly choose to start a business supplying guard services or uniformed security forces but you would not be establishing your own "police" force.
Smokey Bear was found in spring of 1950 near Taos, New Mexico during the devastating Capitan Gap wildfire in the Lincoln National Forest. He was up in a tree, suffering from badly burned paws and hind legs.
Originally named Hotfoot Teddy, he was soon transported to the National Zoo in Washington, DC to perform public service for the rest of his sweetie bear life (26 years). He became the zoo's most popular attraction, eventually obtaining his own ZIP Code from the US Postal Service.
Please see the related link below:
The first mention of Smokey Bear was a war dept poster in 1944 to promote prevention of forest fires, and save the forest wood for the war effort
What are some good brands of sprinkler systems?
There are numerous brands of sprinkler systems. Hunter brand products are popular and are a higher end version. Other brands that have positive reviews are Toro, Rainbird and Raindial.
What product standard is covered by NFPA 1851?
Standard on Selection, Care, and Maintenance of Protective Ensembles for Structural Fire Fighting and Proximity Fire Fighting
Wow. Um. Well, the first use of fire is not possible for us to ever know. Cro-magnon and home sapiens used fire for thousands of years.There are archaeologists that have found remnants from campfires in caves and dated them though. Maybe a site devoted to that may have a better answer.
Which states require fire sprinklers in new single family homes?
New Hampshire RSA 153:5 prohibits the state fire marshal from adopting any state fire codes that "require automatic suppressant or sprinkler systems in detached one- or 2-family dwelling units in a structure used only for residential purposes..." However, state law also allows municipalities to adopt their own codes, subject to state approval, and provided that they are no less restrictive than state codes. RSA 674:36(IV) does, on the other hand, prohibit a municipal planning board from requiring or adopting "any regulation requiring, the installation of a fire suppression sprinkler system in proposed one- or 2-family residences as a condition of approval for a local permit." (Acts of 2011:203(1), eff July 1, 2011)
There are a lot of fire alarm systems depending what kind of an alarm system you want.Fire alarm system with (smoke detectors,heat detectors,flame detectors almost the same with heat detectors,ionized smoke detectors and duct detectors) depending on the system of your needs.For you to understand it I will explain 2 of it.Smoke detectors have smoke sensors in side if the smoke is too much the alarm system starts to work,that means alarm works.How the alarm works the smoke detection system analysis the air which goes through it , if the sensor senses any increase of CO or CO2 then it starts the alarm. Flame or heat detector has a contact which is made of 2 different materials which has different specific heat, İf any heat reaches to this contact according t the different specific heated material contact bends towards the more specific heated material( you can do it with copper and iron at home if you fix them with a nonmetallic material and heat them even with a lighter you will see it with your eyes) than the alarm starts because the contact touches a metallic material to give the energy to the horn or bell.( for more specific information try Notifier or Honeywell
What does P A S S stand for in fire safety?
Pull - Pull the pin on top
Aim - Aim the hose at the base of the fire
Squeeze - Squeeze the handle
Sweep - Sweep at the base of the fire until out
If it doesn't work, drop extinguisher, and run for your life, or walk if it isn't an emergency.
Make sure to call 911!!!
How can fires be extinguished?
There are two key elements of fire combustion and oxygen. If you deprive fire of either then it will extinguish. Another means of containing a fire is to create a fire break wide enough to prevent the flames from bridging the break. Thus water is used to extinguish the combustion of a forest fire as you cannot remove the oxygen. For something like an oil pan or rig fire the method is to starve the fire of oxygen by covering with a towel or using explosives to create a vacuum.
Do National Fire Protection Association standards apply to the US Army?
Not directly. The military has its own fire regulations, which may be based upon NFPA standards, among others.
For example, military regulations may have different hose threads for fire engines used at military installations, compared with what local civilians may be using.
Planning and inspections may also be completely different from what NFPA requires, although federal offices within commercially leased spaces may still be subject to all local codes as well as federal (military) regulations.
