Fire Prevention and Protection

No, there are many different standards that have been adopted or enacted as code in different states, including the International Fire Code and International Building Code, neither of which have any connection with NFPA.

It is less expensive then black steel pipe. And heat ratings allow it to be aprroved for residential application.

"The mission of the international nonprofit NFPA, established in 1896, is to reduce the worldwide burden of fire and other hazards on the quality of life by providing and advocating consensus codes and standards, research, training, and education."

In the US it can be private, local, county, state, or federal

Ordinary fire sprinklers activate (open) when they get hot enough. They may be equipped with a "frangible-bulb" glass vial, which holds the valve shut until the liquid expands beyond a calibrated volume and bursts the glass. They may have a "fusible link", made from various metals and calibrated to separate (melt) at a given temperature, releasing a spring-valve.

Other specialized sprinkler systems cannot be activated until there is also a smoke or other fire detector trigger that allows pressurized water into the system.

One other special type is called "deluge" and the sprinklers do not have valves at all. When the smoke or fire detector (or manual emergency trigger) goes off, the water will pour from every sprinkler head.

Many TV shows and movies use fictional deluge systems for comedic effects when someone "pulls the fire alarm" and sets off the sprinklers, which would not normally occur in a properly designed system.

Either one CAN be used. Galvanized would be preferred in an environment high in chlorine or corrosive materials. Normally though, black pipe, or carbon steel, is used for fire protection because it is much cheaper.

This system is used in a non heated space. Parking garages, warehouses, carports and so on. The system has pressurized air in the pipeing from the sprinlker head to the water source. Water does not enter the system untell a sprinkler head is set off.

There are several NFPA standards that reference fire hydrant requirements, for various parameters, including NFPA 1 Fire Code and NFPA 101 Life Safety Code.

The first fire escape was invented in England in 1784 by Daniel Maseres. Of course, that fire escape was nothing like the type of fire escape that we are familiar with today.

Blue: Health Hazards, on a scale of zero to four

Red: Flammability, on a scale of zero to four

Yellow: Reactivity or Molecular instability increases, on a scale of zero to four.

A number zero means stable, non-reactive, non-flammable and ordinary hazards. A number four means extremely hazardous to health, extremely flammable or extremely volatile.

White: Other Important Information (Special symbols accommodate important information about the chemical compound.) Examples:

W , Reacts unusually or violently in situations where water is present.

OX, Oxidizer. Reacts readily with other oxygen atoms present, sometimes violently.

I guess I would have to say first what kind of back flow? There are lots of them. Then to answer your question has it been along time sense you've used this valve? If so there could be a smallest of chanses. In 20 years in my job I've never had this happen. But I guess there is always a first.

Well, the entire desert is not really flammable. But the grasses or the types of plants which grow in the desert are highly flammable.

Fire safety and prevention is important when camping or grilling outside. Campers should learn and follow the local rules about open fires, camp stoves, kerosene lanterns, and other sources of fire. Know the risk factors that should be assessed and before building a fire, check the fire risk level of the immediate area. After assessing and feeling fairly sure there are no dangerous conditions, clear any brush and other flammable debris from around the fire in a five-foot radius. Do not leave a campfire unattended; be watchful for developing risk factors. Be prepared to extinguish the fire if the need arises, such as during high winds.

Some common sense rules include:

1) Never Leave a Fire Unattended

2) Hold Used Matches In Your Fingers Until They Are Cool.

3) Extinguish All Fires and Burning Coals Or Embers With Water Or Dirt.

Don't know if this answers your question but materials Considered famable include gasses, liquids, and Solids that Can ignite quickly , burn rapidly, and give off intense heat
