Where do you stand when fire sprinklers go off?
if you stand under it, believe it or not, you will get sprayed less.
...or just run. :)
What is the minimum square footage of a house before fire sprinklers are required?
The answer depends upon what fire code applies. There are places where fire sprinklers are not required in one- or two-family buildings at all, where amended national fire codes have been enacted locally.
Why is water not used to put out fire caused by petroleum products?
The fuel (oil, gasoline, etc) is typically trapped in an absorbent material or lying on a surface that is preventing it from burning (by sinking away heat).
Petroleum products have lower densities than water, i.e. they float on top of water. When you add water, it soaks down into the materials present, which causes the fuel to float to the surface. The high temperature causes the water to boil and project bits of fuel and water droplets into the air. If it's hot enough, this will cause the fire to blaze up; otherwise it usually just spreads the fire around.
Hence, fires caused by petroleum products are extinguished by solid or gas fire suppressants (sand, foam ect.) as it forms a layer over the petroleum product on fire, thereby, cutting out the oxygen supply needed for it to continue to burn.
What extinguishes a burning flame?
Water is an extinguisher of a burning flame.
Answer: FUEL: Like us, fires die without food. Firemen exploit this principle in forest and brush fires when they create a firebreak in the path of the main fire. In a kitchen setting, eliminating the fuel may simply mean turning off the gas. In other settings, however, eliminating the fuel may be difficult if not impossible.
OXYGEN: Once again, like us, a fire must breathe. Toss a shovelful of dirt or a fire blanket over a fire, and you smother it. The oxygen level, incidentally, need not go down to zero for a fire to suffocate. If you reduce the oxygen level from the normal 21 percent in the air around us to 15 percent, many substances-flammable liquids, for example, and even some solids-will no longer burn.
Does exit access include exit?
No, under the definitions in the NFPA Life Safety Code, a "means of egress" includes an exit access, an exit and an an exit discharge.
In that sense, "exit access" is everything an occupant must pass through on the way to an "exit", where an "exit" is a door to a safe place, either a fire door into another fire partition, a door outside, a fire door to a smokeproof stairwell, or a fire door into an "exit" comprised of a protected horizontal passageway.
In other words, you use an "exit access" to get TO an exit, and you use an exit to get to an exit discharge (which reaches a public way).
Examples of exit access would include any distance through an unprotected space on the way to an exit, whether it's across an open warehouse floor, across theater seats and down an aisle, or going down an unprotected stairway. Since those areas are not fire-resistant, they are "exit access".
NFPA refers to the National Fire Prevention Association, headquartered in Braintree, Massachusetts, USA.
They maintain a huge website at NFPA.org.
What do you need for a burning to occur?
Fuel, Oxygen and a spark to ignite the flame. Use the Fire triangle.
What happens when you remove fuel and oxygen from fire?
If you remove fuel, oxygen, or both from a fire, the fire goes out.
What does it mean for a muck fire to get smoldered?
The fire is burning underground in the peat or other materials.
Neighbor in ground sprinkler lot line requirements?
Lot line requirements for in-ground sprinklers typically depend on local zoning regulations and building codes, which can vary by municipality. Generally, it's advisable to install sprinkler systems at least 2 to 3 feet away from property lines to prevent water runoff onto neighboring properties and to allow for maintenance access. Homeowners should also consult with their neighbors and possibly obtain permits to ensure compliance with any specific local ordinances. Checking with a local landscaping or irrigation professional can provide additional guidance tailored to your area.
NFPA codes and standards are selected, enacted or amended and enforced by each individual authority having jurisdiction.
There are several other alternatives, including International Codes and locally created codes that could be adopted and enforced in lieu of any NFPA codes.
Another element of NFPA enforcement often involves local insurance needs established by the underwriters.
Why should windows be closed during a fire?
In a situation where you are within a structure that is on fire and you cannot flee to a safer location, you would want to keep windows in the closed position. Opening windows will bring in an air flow in which the fire will flow towards. If there is not oxygen for a fire, it will help to decrease the fire because it is taking away a source of fuel.
He was credited for improving the fire extinguisher in 1872, about 150 years after it had been invented in England.
What he actually invented was a type of fire standpipe and sprinkler in which water pressure from a reservoir and pump pushes water up and into a building to a valve that can be opened to make the water spray out of nozzles. That is nothing like what we call a "portable fire extinguisher" today.
US Patent 125,063, issued March 26, 1872 to Thomas J. Martin [sic], of Dowagiac, Cass County, Michigan.
How does the alarm system on a 1977 Chevy Corvette work?
When turned on, by the door key in the left front fender or driver door lock, it will sound a horn alarm if the doors or hood are opened. The actual horn alarm is located either inside the driver side front or rear fender. Mine still works!
I removed the inside driver side door panel on my '77 and I found a wire burned apart laying in the bottom of the door. I spliced it back together and my alarm works again.
My alarm switch is in the drivers door key. Use the key to lock the car and it turns the system on.
Additionally, if you turn the system on and it trips right away, you have a short somewhere, most likely a bad door/hood/key switch.
Later C3s had a switch for each t-top, as criminals would either steal the tops or remove one and jump inside to hotwire the car without being noticed.
Good luck!-ku2002

Why we Don't place electric heaters near combustible materials?
You should refrain from putting electric heaters near combustible materials because heat emitted from the heater is capable of causing the combustible material to blow up or catch fire.
Can start a fire with plastic?
Yes, you can, but is strongly not recommended. Plastic smokes heavily when burned, releasing toxins. Different plastics release different toxins. Breathing the smoke of a plastic fire is dangerous as well due to the oily soot that is in the smoke.
Do not burn plastic in a campfire.
Fires that have caught in manufacturing facilities plastics are particularly difficult for firefighters to extinguish. The smoke that many plastics release when burned can be flammable as well.
