4. DCC FIRE PROTECTION SYSTEMS homework For the supplied structural layout, create a plan to properly locate extinguishers in this structure for all three hazard levels: –Light –Medium –High You are the building owner and a tight SOB so your goal is to meet the requirements with the fewest number of each type of extinguisher.

5. DCC FIRE PROTECTION SYSTEMS Why Must Firefighters be Knowledgeable in Fire Extinguishers????? They use them They inspect them They may service them Pub Ed- they are viewed as the “experts”

6. DCC FIRE PROTECTION SYSTEMS The purpose of a fire extinguisher is to enable a person with minimal training and orientation to extinguish an incipient fire

The first version of the modern fire extinguisher was invented in the United Kingdom by Captain George Manby in 1816, consisting of a copper vessel of 3 gallons (13.6 liters) of pearl ash (potassium carbonate)solution under compressed air pressure.United Kingdom 1816 gallonsliterspotassium carbonate compressed air

11. DCC FIRE PROTECTION SYSTEMS SODA ACID EXTINGUISHER The late 19th century saw the invention of the Soda-Acid extinguisher19th century A cylinder contained 1 or 2 gallons of water that had sodium bicarbonate mixed in it. sodium bicarbonate Suspended in the cylinder was a phial containing concentrated sulphuric acid.sulphuric acid Activating the extinguisher by striking a plunger to break the phial, or inverting the extinguisher to release a lead bung from the phial (depending on type), released the acid which mixed with the bicarbonate solution to generate carbon dioxide gas that expelled the water under pressure through a nozzle or short length of hose.leadcarbon dioxide
