Fire Extinguishers

Security on todays buildings is not the same as it was in the past. Today you have portable fire extinguishers, safe zones, sprinklers, escape routes and fire extinguisher signs. All of them have been created to reduce the risk of suffering a fatality due to an accident. Thanks to these measures, thousands of lives have been saved around the world.
What Is A Fire Extinguisher?It is a mechanical device created for putting out fires. The history of the fire extinguisher goes back to the 19th century, when George William Manby, Captain of the British militia, noted that firemen in Edinburgh werent able to reach the top floors of the buildings. He made a cylinder of copper which contained water and compressed air. The firemen only need to point the hose to the fire to extinguish it.

During the rest of the 19th and 20th century, this device was continuously improved due to the necessities of the modern world. Better materials and chemicals where implemented, bringing us to the portable fire extinguisher of today.
How Does A Fire Extinguisher Work? Modern extinguishers contain an inner cartridge filled with carbon dioxide, which is the chemical that creates the pressure over the extinguishing agent. Once you push a lever, the carbon dioxide will push the agent and project it through the hose. The pressure will permit the user to point the fire from a safe distance, permitting him to maneuver and control the fire.
