Is the expiry of ABC fire extinguisher really yearly?

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).

Why should i not use a water extinguisher on elextricity fires?

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

How long do the contents of an extinguisher last when opened?

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.

Where can you find a picture of Thomas J Martin the man who invented the Fire Extinguisher?

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.
