Fire Prevention and Protection

Ordinary Hazard Group 1 density is 0.15 gpm/sq ft over 1500 sq ft if wet pipe system Ordinary Hazard Group II density is 0.20 gpm/sq ft over 1500 sq ft if wet pipe system (according to NFPA 13) There are factors that can change the density and area requirements depending on variou sfactors, but in general the above densities/area are correct.

Extra hazard occupancies require densities of either 0.30 gpm/sq ft or 0.40 gpm/sq ft, for which the maximum head layout is 100 sq ft per NFPA 13.

There are some sprinkler heads in the market that allow coverages up to 196 sq ft with a special listing. Tyco EC-25 and EC-17, and Reliable MBEC-14 are some of the heads that can be used with certain restrictions.

Fire sprinklers and supporting pumps are considered "plumbing".

Train people to be aware of fire safety.

Be extremely careful when cooking. Over 40 percent of all residential fires are from cooking.

Do not use open flame where it is not necessary.

Keep flammable liquids and other fuels away from any source of heat or sparks.

Active fire protection includes anything that is triggered to put out a fire or "activates" to stop or slow the spread of fire.

Passive fire protection includes things that prevent fire or spread by simply being in the way at all times.

Backdraft is caused when large amounts of oxygen reenters places where there is both a fire and lack of oxygen. In a building fire, a opened window or door is likely to cause a backdraft.

The smoke and heat will move upward. u should crawl so u can see going and if u are standing up you will see lots of smoke and u will not be able to breath Because heat rises and if you stand straight up and take one breath, It can burn your lungs and kill you.

RTI = response time index. It is a measure of how fast a sprinkler activates, obtained from testing.

A stadium is considered an "assembly occupancy" under NFPA 101 Life Safety Code and NFPA 1 National Fire Code.

Depending upon your particular issues, there would be cross-referenced standards that are also applicable to components such as sprinkler systems, fire extinguishers, construction types, use of LP-powered vehicles inside, etc, not to mention National Electrical Code (NFPA 70) and possibly dozens of others.

Yes, if you mean a "torch" with a flame, such as a propane or butane torch. An electric flashlight, known as a torch in British English, would not have enough heat to set off an ordinary sprinkler.

Exit signs are used to show people the fastest way to get out of a building. These can be essential during an emergency and are mandated to light up so that they can be seen even in a power outage.

Fire safety deals strictly with the measure taken to avoid, control, and stop a fire outbreak, or to safely evacuate people from the location of a fire.

Industrial Safety deals with the measures taken to maintain safety in the workplace, including industries and shops, and to prevent or mitigate injury or property damage

HSE is an abbreviation for "Health, Safety, and Environment." HSE includes industrial safety, precautionary measures taken to prevent ill-health in the workplace from exposure to chemicals, heat, light, etc., and measures taken to avoid or minimize adverse impact on the environment as a result of industrial activity.

It depends upon whether the door is used for egress or simply fire separation. In general, a sliding door cannot be counted as part of a required exit unless it also has an emergency hinged mode to swing out when pushed.

Specific rules of the local building code or NFPA 101 Life Safety Code (and similar) would determine the actual criteria for allowing them, if at all. Similar rules apply to roll-up fire doors that deploy automatically.

Sliding fire doors that are not within any exit path could have as much as a 5-hour fire rating, be automatically closing, could weigh hundreds of pounds, could automatically latch into place, and would probably kill anyone who got in the way or became trapped without another exit from smoke or fire.

Fire sprinklers have two major components that operate in response to a fire: the fire sprinkler heads which are connected via a series of pipes to a fire pumps. Water pressure is kept in the head by a series of valves in the pump. and is kept in the heads by little vials of colored liquid.

During a fire, the liquid inside the sprinkler heads heats up and starts to expand, eventually causing the vial to burst. Water that was kept in the pipes pours out of the sprinkler heads.

The water pouring out of the sprinkler heads causes the pressure in the fire pump to drop. In response, the pump kicks on and pumps more water from the municipal water supply to keep the sprinkler flowing.

NOTE: this is how "wet pipe" fire sprinklers, the most common types of fire sprinklers, work. Other sprinklers (dry pipe, deluge and pre-action) are slightly different.

There are lighted signs at all exits and in complicated buildings, signs with arrows pointing towards the exits. These signs are standard size, lighted withe word "EXIT" in red, although green is gaining in popularity.

The international symbol for an "exit" sign is a "running man with a door frame", often in green and white. These signs sometimes include directional arrows to indicate how to proceed toward an exit.

maybe... water?

The duration for watering your garden with a sprinkler typically ranges from 20 to 30 minutes, depending on the type of plants and soil. Aim for approximately 1 inch of water per week, including rainfall. To determine if you're achieving this, you can place a small container in the garden to measure the water output. Adjust the time based on your specific garden needs and local climate conditions.

Structural steel loses a large amount of its rigidity when heated. To prevent a premature collapse of a steel structure, approved insulation is applied to the steel after it has been installed, often in the form of spray-on foam or other materials.

They absorbed central sprinkler co.

Fire ratings are generally based upon testing of a structural sample. A galvanized sheet, by itself, would not have a fire rating. If combined with gypsum or other materials in an assembly, it could be subjected to the standard tests and rated for use in that configuration.

That said, 1.5mm sheet steel can be used in assemblies rated 1 to 4 hours.

Class A- ordinary combustibles, such as wood or paper- leaves an Ash

Class B- liquids- such as oil, gasoline. Liquids Boil

Class C- has a live electrical Current

Class D- metals, such as magnesium. Metals can Dent

Class K- a Kitchen fire, such as burning fat.
