How do you calculate a Fire occupancy Load?

The primary factors in the calculation are: the type of occupancy, along with the available floor space and the available means of egress.

When creating or modifying a building, the building use and occupancy load determine the fire resistance requirements. Or the desired type and occupancy load may help determine the necessary area and means of egress.

Buildings are classified by the ICC (International Code Council) by group and division.

Groups - defined

Group A - Assembly

Group B - Business

Group E - Educational

Group F - Factory and Industrial

Group H - Hazardous

Group I - Industrial

Group M - Mercantile

Group R - Residential

Group S - Storage

Group u - Utility

Each group mostly has more than one division, categorized by number; I.E.

Group A Division 1 , which is the most stringent category for fire resistant materials and means of egress code rules, is more stringent than Group A

Division 4.

Like wise , Group U Division 2, which is the lowest requirements is less stringent

than Group U Division 1 requirements.

In summary, the lower the letter and number, the more stringent are the fire

resistive , and means of egress components.

To know the fire resistive construction and means of egress requirements of your building, consult the building code book for your state ; which may supersede

the I.C.C.

To be absolutely sure ,consult with your local building department with information about what kind of use the building is intended for , how big of an occupancy intended , and whether or not it is connected or near to another business of same or different classification.

What do firefighters do when there's no fire?

In addition to their obvious role, firefighters also function as medical responders. They get dispatched to emergencies in the hopes that they can provide some medical aid before paramedics arrive. When there are no calls to respond to, firefighters do the following:

  1. Preparing — Firefighters need to make sure they are ready at a moment’s notice. This involves checking that the trucks and equipment are always in good working order.
  2. Training — Firefighters are constantly required to learn new skills. This includes medical training as well as fitness and equipment training.
  3. Public Outreach — Firefighters sometimes speak at special events and cover topics ranging from exit drills in the home to wildfire safety.
  4. Reporting — Firefighters are required to document every incident they respond to, no matter what.

Are exit signs required to have battery backups?

Exit signs in public, commercial and industrial locations must have a back-up means of remaining illuminated should the power fail. Most signs meet this requirement with a back-up power supply, such as a battery.


There are special exit signs that use phosphorescence (photoluminescent) material (glow in the dark) that remains illuminated for a short time after a power failure.

Also, some occupancies are not required to have "emergency lighting", perhaps because they are small enough to safely evacuate without lights, and exit signs in such an occupancy are not required to have any backup power at all.


So, technically, no, not all exit signs are required to have a battery backup. You might want to consult NFPA 101 "Life safety Code" at the library for all the details on exit sign lighting, as well as exit illumination. NFPA 101: 7.10.4, for example, any required emergency lighting must to last for at least 90 minutes, and it must illuminate the exit signs that are not photoluminescent, but not every occupancy requires emergency lighting, let alone backup, or lighted exit signs.

What should you do in case of fire in your home?

In case of a fire in your home:

  1. make sure everyone leaves the house immediately, closing doors as you go;
  2. get to a safe place and call the Fire Department;
  3. do not reenter the house for any reason until the fire is out.

Many deaths and injuries each year are due to re-entering to "save a pet", which is noble, but could be extremely dangerous if the fire has grown.

Obviously, if you can safely put a small fire out immediately, do so. It is better to put out a small fire than to stand there and watch it burn the whole house down.

Keep a small portable ABC fire extinguisher near the kitchen and near any other heating appliance (wood stove, fireplace, furnace). Know how to use it.

If there is a fire in the oven, close the oven and switch it off -- the fire may suffocate. Similarly, if there is a greasy-pan fire on the stove, maybe try to put a large lid over it, or even throw a wool blanket on it -- still better than losing the whole house.

Answer: While many homes do not have fire extinguishers, factories, offices, and public buildings are often required by law to be equipped with them. The basic types are water, wet chemical, foam, dry powder, and carbon dioxide.Dry powder extinguishers chemically inhibit combustion and come close to being the universal fire retardant. Not only is dry powder effective against both class A and class B fires but it is also useful in combating class C (electrical equipment) fires. Understandably, this multipurpose extinguisher offers excellent protection for your home. Dry powder tends to make a mess-but then a mess might be a small price to pay!

Pressurized water extinguishers are ideal for fires involving paper, wood, plastics, rubbish, or fabrics. These are often called class A fires. Water's potency as an extinguishing agent stems from its great capacity for absorbing heat. In sufficient volume, water simply steals heat faster than the fire can regenerate it, and thus the fire dies out. But do not use water on flammable liquids. You merely spread the fire-explosively! Also, because water conducts electricity, you should not use it or any extinguisher that incorporates it where there may be live electrical wires.

Wet chemical extinguishers employ a pressurized solution of alkali salts in water and are particularly effective against fats and cooking oils but not against petroleum products. They are also effective against class A fires.

Foam extinguishers work well, not only on class A fires but especially on fires involving flammable liquids (industrial lubricants, fuels, paints), generally known as class B fires. There are two kinds of foam extinguishers, so check which one best suits your needs. When applied to a burning liquid, the foam coats it with an impervious film that arrests flammable vapors and also keeps oxygen away. Thus, foam must be applied more gently so that it does not penetrate the liquid but, rather, spreads readily over it. Be careful not to use foam near electricity.

Carbon dioxide extinguishers can be used against practically all fires except gas fires. They work on the principle that carbon dioxide displaces oxygen. But as we saw earlier, if the combustible keeps its heat, spontaneous reignition is possible. Carbon dioxide is a gas, so a breezy, open environment limits its effectiveness. Its cleanness, however, makes it the extinguisher of choice for use on delicate machinery and electronic equipment. In confined spaces, though, carbon dioxide can asphyxiate, so if you use it in such a setting, be sure to leave when the fire is out and shut the door behind you.

The fire blanket* is a handy fire fighter and is ideal for small, contained fires such as you might have on the top of a kitchen stove or in a small patch of carpet. Just pull the blanket from its tidy little wall-mounted holder, stretch it out in front of you to protect yourself from the flames, and place the blanket over the fire. Of course, if you have not already done so, turn the heat source off immediately if at all possible.

Fire blankets are also lifesavers should your clothing catch fire. In that event, remember this vital rule: "Stop, drop, and roll." Never run; you simply fan the flames. If you or anyone else is able to wrap a fire blanket around you as you roll, you will snuff the fire out even more quickly.

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 does fire need oxygen?

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.

How does dry riser sprinkler system works?

The term 'dry riser' refers to the fact that the pipes feeding the sprinklers are empty until needed. Once the sensors detect a fire or smoke, they trigger the valves in the system to let water flow to the sprinkler heads - since the water is under pressure - this takes only a couple of seconds.

How does heat move from a fire up to a fire sprinkler?

Since hot air is lighter than cool air, heat, especially the high heat from a fire, moves up to the fire sprinkler heads on the ceiling the ceiling rapidly. When the heat gets too great, heat sensitive bulbs contained in the sprinkler heads burst and release pressurized water from behind the bulbs.

What's the difference between a wet and dry fire sprinkler system?

The difference is what the pipes normally contain while standing by for a fire.

  • A wet sprinkler system has pressurized water inside the system 24/7 for extinguishing a fire when any sprinkler head gets hot enough to open.
  • A dry sprinkler system has pressurized air or nitrogen inside the piping. This keeps a dry-valve closed, and water out of the system. When a sprinkler fuses (opens), it allows the air to escape; then the dry valve opens and allows water to enter the system. Wherever there is an opened sprinkler, water will flow through it and put out the fire.

Dry systems are used in areas where water filled piping could freeze, such as unheated warehouses, freezers, unheated buildings, etc.

Additional precautions can also be taken to avoid accidental flooding when a sprinkler head is damaged. For example, a dry-valve controller may wait for a signal from a fire alarm panel before turning on the water.
