Fire Extinguishers

Depending on the fire bylaws in your area, the CERTIFICATION of an ABC extinguisher may expire yearly. Most areas require all commercial and industrial extinguishers to be inspected and re-certified by a licenced inspector annually.

Most commercial establishments contract out their fire protection systems, and that contracted company will automatically provide annual inspections, recertifications, and equipment replacement as required.

In terms of a residential or personal extingisher in your home, best practice calls for annual or semi-annual inspection. This is as simple as checking the pressure gauge to ensure it reads within the green or 'charged' zone, and is not over or under charged. Since an ABC extinguisher contains a dry chemical which can settle over time, it is also advisable to invert the extinguisher for a few seconds to allow any settled chemical to lift off of the bottom. (You will be able to hear movement within the cylinder if you listen closely).

If an extinguisher has been partially discharged, it should be recharged or replaced at once. Some extinguishers- notably the dry powder type, will begin to leak the propellant gas, and lose all pressure within a few days. This is due to powder preventing the release valve from fully seating.

The amount of time the contents of an extinguisher will continue being expelled from an extinguisher when the extinguisher is "opened" to extinguish a fire depends on the size of an extinguisher and how the user chooses to employ it (continuous or in bursts). Most easily portable extinguishers will last for less than a minute if held open for continuous use.

Water conducts electricity; therefore, using water to extinguish an electrical fire can result in electrocution.

It's NOT class A - which is flammable solids.

Electrical fires are class C

(burning liquids are class B, burning metals are class D)

Artificial rain, or cloud seeding, was first used to combat fires in the 1940s. One notable instance occurred in 1947 when scientists in the United States conducted cloud seeding experiments to induce rain over a wildfire in New Mexico. This method aimed to enhance precipitation and help control the spread of the fire. Since then, cloud seeding has been utilized in various regions around the world to assist in firefighting efforts.

You can find a picture of him on google. Just go to google and search up thomas J Martin Images and his pics will show up.. or click on images on the left side :) youre welcome

Also worth noting that Thomas Martin may have invented "A" fire extinguisher, but not "THE" fire extinguisher. Today, his invention would be properly titled as "Method of piping water inside for use in fire suppression." It has nothing to do with a PORTABLE fire extinguisher, which was invented at least 70 years earlier.

Metals such as aluminium magenesuim etc

Kindling is material that is used for starting fires. The material is easily ignitable. Kindling is usually found in the form of dry sticks of wood.

Unfortunately no. The "smoke" will be rather small and there is an extreme freeze risk for anyone holding the bottle and sprayer.

The FireStopper advantages are:

1. extinguishers are all independently Tested, Rated & Listed ABCDK instead of all other extinguishers that are either single class rated, 2-class rated or 3-class of fire effective @ ratings.

2. all are Eco-Friendly ("Green"), Non-toxic, Non-irritant & Non-agressive.

3. liquid (water based), easy to clean, small (compact) & freeze resistant to -100 degrees F (without the use of harmful antifreeze).

4. safer for the user because the FireStopper extinguisher content always produce retardant properties to maintain post-fire security unlike all other potable extinguishers.

"James Beverly Ward and son wrote the Thos. J. Beale yellow ore hoax

story to never end also was not true.

Hear us now, we tell you the truth."

owes slave Tom $1.00 to burn town."

Carbon Dioxide extinguishers are used for plenty types of fire. It's most effective against fires corresponding to flammable liquids, electrical equipment, cooking oils & fats. Do NOT use a Carbon Dioxide extinguisher for solids (wood, paper, cloth, etc) and flammable gases.

Certainly not ! Class B fires include petrol/oil fires as well as grease (chip pan) fires. Using a water extinguisher will not extinguish these types of fires because - since the flammable substance will float on water - it simply heats the applied water, turning it to steam - resulting in an explosive 'cloud' of burning vapour.

There are no benefits. The water combined with electricity could electrocute you.

Class A fire extinguishers are used on Class A fires, that is, "ordinary combustibles" such as wood, paper, cloth, rubber and small amounts of plastics.

Because it may contain conductive water, a Class A should never be used on an any other type of fire -- there could be a dangerous reaction.
