Fire Extinguishers

Fire extinguishers are used in homes, schools, businesses and boats as a way to put out a small fire. Fire extinguishers come in many types for different purposes, including portable or fixed systems. This category relates to the science, origins, operation, selection and standards for fire extinguishers.

Are Fire extinguishers recommended in food delivery trucks in California?

I do not think they are required, but since the food trucks have heating and cooling elements, maybe they are more likely to have fires and can be used in the case of a fire to prevent further damage to the truck until the Fire Department arrives.

Are red fire bomb extinguishers dangerous?

Grenade-type extinguishers made before the mid-20th century contained carbon tetrachloride. This chemical is poisonous, carcinogenic, and, if used to fight fire, produces a poison gas previously used in warfare. They are quite dangerous.

What is the standard color of fire extinguishers in the UK?

The standard colour of fire extinguishers in the United Kingdom is a signal red body with another colour banding depending on the kind of fire extinguisher.

When bellows are used to below air on to a fire the fire burns birghter?

When bellows are used to blow air onto a fire, they increase the oxygen supply available for combustion. More oxygen allows the fuel to burn more efficiently and at a higher temperature, resulting in a brighter flame. This process enhances the fire's intensity and can help it consume fuel more rapidly. Consequently, the increased airflow from the bellows contributes to a more vigorous and luminous fire.

What cant a fire extinguisher put out?

Fire extinguishers are only intended for small fires. Any larger fire will need professional help, so the sooner the fire department is called, the sooner they will get there.

If there is water in the pressure gauge of a fire extinguisher is it OK to use?

No. The diaphragm on the pressure gauge is leaking, and the gauge will soon be inoperative. Have the extinguisher serviced and repaired.

How many fire extinguishers are required aboard an 18 foot powerboat with installed fuel tanks?

At least one USCG-approved Class B-1 fire extinguisher is required on any powerboat, unless it is under the following exception:

  • "motorboats less than 26 feet in length,
  • propelled by outboard motors and
  • not carrying passengers for hire, need not carry such portable fire extinguishers if
  • the construction of such motorboats will not permit the entrapment of explosive or flammable gases or vapors" [bullets added]

A UL-listed 5-B:C extinguisher, with 2 pounds of dry chemical, may provide the basis for the extinguisher, but it must ALSO conform to USCG-approvals (proper corrosion protection, labeling, mounting bracket, etc).

True or false you should not try to put out a gasoline or diesel fire with water?

True, you should not try to put out a gasoline or diesel fire with water. This would make the fire spread. Smother the fire with something non-flammable such as a safety blanket, or use a proper fire extinguisher.

How is the fire test for dry chemical fire extinguishers conducted?

Your question wasn't really clear but I'm assuming you mean how do you test a dry chemical fire extinguisher at home. Normally these types of extinguishers are tested at home by simply turning them upside down and listening to them to make sure the dry powder hasn't started to cake in the bottom. If you hear the sound and the gauge on the top of the bottle shows in the "green" the extinguisher is fine. Don't try to test them by pulling the trigger and seeing if they shoot, there's not a heck of a lot of powder in there to play around with.

What fire extinguisher do you use for a vacuum on fire?

A vacuum is nothing. A nothing can't burn, so there is no need to put it out.

If you are talking about a vacuum cleaner (electrical appliance) on fire, that is an energized electrical fire, which is a Class C fire. You will need a UL class C rated fire extinguisher for this emergency (i.e., ABC, B:C, or C).

If you can unplug the vacuum safely, then do so. This converts the fire from Class C to "ordinary combustibles", UL Class A.

Can you put a fire extinguisher in checked baggage on a jet?

According to the Canadian Air Transport Security Authority (CATSA)'s website the answer is "No". Probably because fire extinguishers are explosive and have to be packaged and transported in a specific way, according to Dangerous Goods handling procedures.

What to do is transformer got fire?

It can be extinguished by usin powder extinguisher or CO2. If not available that tind, get a detergent and soak it in water, mix it and pour it on the fird.

What is the fire dampers?

Frequently Asked Questions About Fire and Smoke Dampers
  • What is the purpose of a fire damper?
  • Fire Dampers are used to maintain the required ratings of fire rated barriers (walls, partitions, floors) when they are penetrated by ductwork.
  • How does a fire damper work?
  • When a rise in temperature occurs a fire damper will close and prevent the spread of flame through the barrier. Dampers are typically curtain style that will close (shut) when a fusible link melts. The fusible link typically melts when the temperature rises to 165 degrees Fahrenheit. In some circumstances higher degree fusible links (e.g. 212°F) are installed in ductwork with consistently higher normal temperatures, such as hot decks in dual duct systems. Fire dampers are certified by Underwriters Laboratories (UL) to carry hourly fire resistance ratings, typically 1.5 to 3 hours.
  • What is the purpose of a smoke damper?
  • Smoke dampers are used is ductwork and air transfer openings that are designed to resist the passage of air and smoke. Smoke dampers may be required in smoke barriers and other smoke controlled systems.
  • How does a smoke damper work?
  • Typically smoke dampers are operated by smoke detectors in the ductwork that will close the smoke damper when smoke is detected. Smoke detectors often are hard wired to a central alarm panel in which the alarm will relay a signal to the smoke damper to cause smoke damper closure. The closure of smoke dampers are done by an actuator - the actuator is either electric or pneumatic. The actuator utilizes the jackshaft and linkage to open and close the blades of the smoke damper. Smoke dampers are UL certified with an air leakage class rating.
  • What is a Combination Fire and Smoke Damper?
  • These dampers are used in areas where both smoke and fire barriers are located to prevent the passage of both smoke and flames.
  • What is a Corridor Damper?
  • Corridors are means of egress travel to an exit. Corridor dampers are fire and smoke dampers that have been designed for use in corridors.
  • What is a Ceiling Damper?
  • Ceiling dampers lessen the passage of heat in fire resistance ceilings where ducts are made only through ceilings.
  • What is a fire barrier?
  • Fire barriers are fire-resistant rated horizontal or vertical assemblies designed to stop the spread of fire.
  • What is a smoke barrier?
  • Either vertical or horizontal, the smoke barrier is a continuous surface such as a wall, floor, or ceiling constructed to restrict the movement of smoke.

What type of fire extinguisher for class 2 gas?

Class 2 gas only means it's compressed and includes flammable/combustible, poisonous and inert (non-flammable, non-toxic) gases.

You would only need a fire extinguisher for flammable gas, which is Class B.

How does Boyle's law apply to fire extinguishers?

When it comes to fire extinguishes, the smaller the volume of the extinguisher the more pressure the gas has. So if the size of the fire extinguisher is small, the pressure might be high.

In which episode does Peter beat up Meg's friend with a fire extinguisher?

Well to be more precise, it was Connie DeMico, (certainly not Meg's friend) and technically Peter didn't beat her up with a fire extinguisher, he slammed her head against one, but that scene is from "Peter's Daughter"
