Fire Prevention and Protection

Probably. In class 1 div 1, seals are required for enclosures that contain apparatus that can produce arcs, sparks, or enough heat to be an ignition source.

The municipal water department is usually responsible for all aspects of supplying water for domestic use, fire hydrants and standpipes in commercial occupancies. The water department will have the necessary data, or can obtain it, as well as the software to determine available fire flows under different scenarios (e.g., multiple sprinklers going internally, first arriving engine pumping 1,000 gpm from nearest hydrant, second alarm tapping two additional fire hydrants, etc).

The number of extinguishers will be based on the size of the building as well as the type, location and size of any specific hazards that may be present such as a commercial kitchen or storage for flammable liquids.

The "no water" symbol means that the hazardous substance will have an adverse reaction to contact with water including possible fire, explosion, release of toxic or corrosive fumes or liquids, release or spread of flammables, or other hazards.

NFPA 10 Standard for Portable Fire Extinguishers deals with them, among others.

NFPA 1 National Fire Code tells you how many of each type of extinguisher you generally need. Other specific standards refer to specific types of hazards.

a wet syestem always has water behind the head it is charged with water at all times all the pipeing is water.. wet system usually used in doors

a dry system has a diffrent type of valve allowing a clapper inside the valve to have water from the underground being held back by air in which the system is charged with air until the valve trips (usually sprinkler being popped or very low air pressure) so the sprinkler system it self on a dry valve contains air until tripped then water flowes when tripped usually used outside parking garages and canopys or where very cold

In NYC about $52,000-$59,000; depending on the job requirements and location based.

A cardboard box may catch fire spontaneously, but it would be rare. It would require a lot of heat, possibly from the sun through a window, but even that is not likely to cause it. Of course, it is best to keep cardboard boxes out of direct sunlight.

If the surge strip catches on fire, unplug it from the wall outlet and use a fire extenguisher or sand to smother the fire.

Fire Safety is the paperback edition of the book by Home Office and Health & Safety Executive published by Stationery Office Books on December 31, 1998

California requires sprinkler systems in newly built one and two story residences. Sprinkler systems are also required for condominiums.

foam

That would depend upon the type and amount of fuel, the humidity in the fuel, orientation to the sun, the weather and the incline of the vegetation.

Too many firefighters have been killed trying to outrun a fire in knee-high grass.

Even if the fire didn't get near the dishes, the smoke and soot probably did. Luckily dishes are nonporous so you can wash away any residue and odor fairly easily.

That is simple. Look for one or more air pumps at the sprinkler system riser. The pump(s) will have a gauge, also, in the line showing what the current air PSI may be at any given time. The gauge may be labeled on its face "Air" but it may not be so marked. A sprinkler contractor's test report to the customer will also show whether the whole system is an air system or if it has both air and "wet" systems present in the building.

Cosmetic damage is a degree of physical damage that simply refers to impairment of only the appearance of a covered item, but not its functionality. Example: Discoloration

No, some weed killers are not flammable, but yes, others are. Some herbicides, such as those containing the active ingredient glyphosate, include among their features non-flammability. But they may produce such super-combustible gases as hydrogen when they come into contact with non-stainless steels, a reason why holding tanks and mixing containers must be made of non-steel substances such as plastic.

no because it might damage your hair because there might be something wrong with it

Yes. Many of the foam insulations (including expanded polystyrene) are highly combustible, and may not be used except when installed under a fire resistive covering, such as drywall.

Fire cannot start without oxygen, so some closed containers will not burn. Wood and other products treated with fire retardant may also not burn. Metals may not fuel a fire, but would be affected if the temperature is right.

A water gong is typically arranged to alarm the instant water in the sprinkler system begins flowing, certainly within a few seconds, as the pressure drops on the sprinkler side, allowing water pressure to turn the clapper in the gong.

Fire extinguishers are required according to local, state or federal fire codes, as may apply to the particular structure. Some "small rooms" may need their own extinguishers.

Under the NFPA 1 Fire Code, nearly all types of occupancies other than one- and two-family dwellings are required to have at least one portable fire extinguisher, even if there are fire alarms, fire sprinklers and "fire-proof" construction. NFPA 1 (2009): Table 13.6.2 Portable Fire Extinguishers Required (by occupancy use).

For example:

There must be no less than one fire extinguisher within 75 feet of any Class A Hazard and within 30 or 50 feet of any Class B hazard (depending upon size of extinguisher and type of hazard). NFPA 1 (2009): Table 13.6.8.2.1.1 Fire Extinguisher Size and Placement for Class A Hazards and Table 13.6.8.3.1.1. for Class B Hazards.

Fire sprinklers are used to protect buildings from fires by dousing them with water provided by a fire pump. Water fights fire by removing the heat, cooling down burning surfaces and interrupting the combustion process.
