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.
Many house fires are caused by cooking accidents in the kitchen. Frying on a stove is dangerous and unattended cooking fires account for almost half of ALL interior house fires!
Other common sources of house fires include:
- chimney fires, improperly installed or maintained heating equipment
- electric heater or wood stove too close to combustibles
- smoking materials falling on combustibles
- improper disposal of wood-stove or fireplace ashes
- worn or overloaded electrical cords or power strips
- hot light fixtures too close to combustibles (e.g., halogen lamps)
- children playing with fire (including candles, matches, lighters)
- fires spreading from an outside fire (rubbish, woods, vehicles)
What a RACE means in a Fire Safety?
RACE is an acronym that is useful in a hospital fire emergency. It may help to remember:
R - Remove patient from the area
A - Alert help, call 9-1-1
C - Confine the fire (close doors)
E - Extinguish small fire, if able to do so safely
It is related to the acronym REACT.

What government is most responsible for providing police and fire protection?
Depending on the location, it will probably be a local government. In the United States, there are local municipality governments, County governments, State governments, and the Federal government.
If you live within a city's boundaries, the city government is primarily responsible for emergency services. If you are not in what is designated as city limits, you may be protected by county provided services such as the Sheriff's office, County Police Department, or Fire-Medical services.
Some governments do not have the resources available to provide emergency services, so rely on nearby jurisdictions or a higher agency.
For example, if a city has no police department or no officers available, they will rely on County/State/Federal agencies to be able to assist them with protecting their citizens.
Alternatively, some governments actually contract out to privately-owned services. This is commonly seen with Emergency Medical Services more than any other emergency service.
Many countries operate in a similar function, but there are also many that operate in a variety of different ways. If you are concerned about who is responsible for providing you emergency services, please contact your local government and they should be able to assist you.
What does the term fire triangle mean?
The fire triangle is now mostly disused, but it consisted of 3 sides, heat, fuel and oxygen.
It was discarded for the "Fire Tetrahedron" which adds in an ignition source.
It is a graphical representation of the 3 things any fire needs:
1)Fuel
2)Oxygen
3)Heat
What is the colour code of diesel pipe line as per NFPA standard?
As per Indian standard its Brown colour.
--------------------------------------------------------------------------------
There is no specific code for coding pipelines in the US, different industrial plants use different color schemes. Gray pipe with a dashed red stripe painted every 6 feet, yellow pipe with a solid red stripe every 6 feet, solid orange pipe (solid red pipe is always fire protection systems according to NFPA rules), brown pipe with red or black stripes every 6 feet....and so on.
The oxygen that a fire needs is used to support the chemical reaction which takes place when something burns. The oxygen is used along with heat to convert the fuel, which typically is composed of hydrocarbons, to mostly carbon dioxide and water. Without the oxygen the fire would die out, because the chemical reaction couldn't take place without it. A fire needs three things in order to remain burning: fuel, an adequate supply of oxygen, and a sufficient heat source.
Oxygen does not itself burns but supports burning.If the burning substance does not get adequate amount of Oxygen the burning of a substance willl b reduced and fire wouldn't rise much.It will blowed off.
What is mean by deluge valve and its function?
It's type of valve used in fire water system for fire protaction.
There are two reasons. First, a closed room does not allow smoke to escape. Smoke inhalation can be deadly. Second, fire consumes oxygen, which we need to breathe. In an open space, we can easily get more oxygen from the surrounding air, but it is harder for fresh air to enter a confined space.
Where do you place your hands to see if a door is hot from a fire?
First on the door handle (carefully). Then on any thinner panel.
Why is CO2 unsuitable for electric fire?
You are wrong, CO2 is particularly used to extinguish electrical fires.
According to the EPA:
(...) some of the types of hazards and equipment that carbon dioxide systems protect are "flammable liquid materials; electrical hazards, such as transformers, switches, circuit breakers, rotating equipment, and electronic equipment (....)
and they also mention the reason:
Carbon dioxide is the most commonly used "inert" gas extinguishing agent, followed by nitrogen (Friedman 1992) (...) Carbon dioxide fire extinguishing systems are useful in protecting against fire hazards when an inert, electrically nonconductive, three-dimensional gas is essential or desirable and where clean up from the agent must be minimal (...)
NFPA 1031 addresses the professional performance levels and qualifications for fire inspectors and plans examiners.
Where do you position the emergency switch for an oil burner?
Wherever you are most likely to be when you discover an emergency. I'm not being flippant; that's the right answer.
If this oil burner is large (I have no way to know from your question) you might place it near your exit since in an emergency you will likely be leaving the area and can hit the switch as you leave the room. You also want it placed so it isn't accidentally triggered.
