OVERVIEW Fire basics Fire extinguisher overview Types of fire extinguishers Following the P.A.S.S. Technique
INTRODUCTION Fire extinguishers are designed to put out orcontrol small fires Small fires, if not checked immediately, canspread out of control It is important that we equip our facilities withthe proper fire extinguishers as part of our fireprotection plan
STAY INFORMED Implementing a fire extinguisher safetyprogram and informing occupants ofthe specific building’s fire safetyprocedures is essential Knowing the different classes of fire andtypes of fire extinguishers CAN savelives
FIGHT OR FLEE A fire is the most common type of emergency businessesmust plan for A critical decision when planning is whether employeesshould fight a small fire with a portable fire extinguisher, orevacuate Small fires can often be put out quickly with a portablefire extinguisher Employees must understand the use and limits of aportable fire extinguisher, and the hazards associatedwith fighting fire
FIGHT OR FLEE EXAMPLE
FIRE EXPLAINEDFor fires to exist, four elements must be present at the sametime:1.Enough oxygen to sustain combustion2.Enough heat to raise the material to its ignitiontemperature3.Some sort of fuel or combustible material4.This chemical reaction is fireOxygen Heat Fuel Fire
4 CLASSES OFFIRES1. Wood-based, cloth, paper, rubber, certainplastics2. Flammable liquids, gases, greases, Petroleumproducts3. Energized electrical equipment, conductors,or appliances4. Combustible metals such as sodium,potassium, or magnesium
FIRE EXTINGUISHERSEXPLAINED Portable fire extinguishers apply an extinguishing agent thatwill either: Cool burning fuel Displace, or remove oxygen Stop the chemical reaction When the handle is compressed, it opens an inner canisterof high-pressure gas that forces the extinguishing agentfrom the main cylinder through a siphon tube, and out thenozzle A fire extinguisher works much like a can of hair spray
EFFECTIVENESSThe following conditions must be met for a fire extinguisherto be effective: The extinguisher must be right for the type of fire It must be located where it can be easily reached It must be in good working order The fire must be discovered while it is still small The person using the extinguisher must be trained to use itproperly
LABELING All portable fire extinguishers must be approved bya nationally recognized testing laboratory to verifycompliance with applicable standards Underwriters Laboratories, Inc. (UL) Factory Mutual Research (FM) Equipment that passes the laboratory’s tests arelabeled and given an alpha-numeric classificationbased on the type and size of fire it will extinguish
TYPES OFEXTINGUISHERSDifferent types of fire extinguishers are designedto fight different types of fires. The three mostcommon types are:1. Air-pressurized water2. Carbon Dioxide3. Dry chemical
AIR-PRESSURIZED WATER Water is one of the most commonly used extinguishing agents fortype A fires You can recognize an APW by its large silver container They are filled 2/3 with water, then pressurized with air In some, detergents are added to the water to produce a foam They stand 2-3 feet tall and weigh about 25 pounds when full APWs extinguish fire by cooling the surface of the fuel to removethe heat from the fire triangle Designed for Class A (wood, paper, cloth, rubber and certainplastics) fires only
APW SAFETY Never use water to extinguish flammable liquid fires. Water is extremely ineffective at extinguishing this type of fire and may makethe fire spread Never use water to extinguish an electrical fire Water is a good conductor and may lead to electrocution if used to extinguishan electrical fire. Electrical equipment must be unplugged and/or deenergized before using a water extinguisher on an electrical fire
CARBON DIOXIDE This type of extinguisher is filled with Carbon Dioxide (CO2), anon-flammable gas under extreme pressure These extinguishers put out fires by displacing oxygen Because of its high pressure, when you use this extinguisherpieces of dry ice shoot from the horn (also a cooling effect) You can recognize this extinguisher by its hard horn and absentpressure gauge CO2 cylinders are red and range in size from 5-100 lbs. or more CO2 extinguishers are designed for Class B and C (flammableliquid and electrical) fires only
CO2 SAFETY CO2 is not recommended for Class A fires because they may continueto smolder and reignite after the CO2 dissipates Never use CO2 extinguishers in a confined space while people arepresent without proper respiratory protection
DRY CHEMICAL Dry chemical extinguishers put out fires by coating the fuel with athin layer of fire retardant powder, separating the fuel from theoxygen This powder also works to interrupt the chemical reaction,making these extinguishers extremely effective Dry chemical extinguishers are usually rated for Class B and C firesand may be marked multiple purpose for use in A, B, and C fires They contain an extinguishing agent and use a compressed,non-flammable gas as a propellant Dry chemical extinguishers will have a label indicating they may beused on Class A, B, and/or C fires
WHERE TO FIND Extinguishers will frequently be found in: Industrial vehicles Hallways Mechanical rooms Offices Computer labs Flammable liquid storage areas
USING AN EXTINGUISHERThe following steps should be followed when responding to incipient stage fire (the fire is limited to theoriginal material ignited): Sound the fire alarm and call 911 Select a safe evacuation path before approaching the fire Do not allow the heat, smoke, or fire come between you and the evacuation path Discharge the fire extinguisher with its appropriate range using the P.A.S.S. technique (pull, aim,squeeze, sweep) Back away from an extinguished fire in case it flames up Evacuate immediately if the fire extinguisher is empty and the fire is not yet out Evacuate immediately if the fire progresses passed the incipient stage While in the process of evacuating, make others aware of the fire
P.A.S.S. TECHNIQUE Pull Aim Squeeze Sweep
P.A.S.S. TECHNIQUE Pull Pull the pin. This will also break the tamper seal
P.A.S.S. TECHNIQUE Aim Aim low, pointing the extinguisher nozzle (or its horn orhoses) at the base of the fireNote: do not touch the plastic discharge horn on CO2extinguishers, it gets very cold and can damage skin
P.A.S.S. TECHNIQUE Squeeze Squeeze the handle so that it will release the extinguishingagent
P.A.S.S. TECHNIQUE Sweep Sweep from side to side at the base of the fire until theextinguisher is completely empty assuring that the fire isout

The fire is spreading rapidly. Only use a fire extinguisher when the fire is in its early stages You don't know what is burning. Unless you know what is burning, you won't know what type of fire extinguisher to use. You don't have the proper fire extinguisher
The successful use of a fire extinguisher depends on the following conditions: The extinguisher must be easily accessible and in good working order. The extinguisher must be the right type for the fire. The fire must be discovered in its incipient stage for the extinguisher to be effective. Extinguishing Fire
How to Use a Portable Fire Extinguisher Remember the acronym, "P .A . .SS ." P Pull the Pin . A Aim extinguisher nozzle at the base of the flames . S Squeeze the trigger while holding the extinguisher upright . S Sweep the extinguisher from side to side, covering the affected area with the extinguisher agent . Remember:
If you are in an Extinguisher Training scenario (Type 1 scenarios) - extinguishers will be located nearby (Figure 16). To run this training type, follow the steps below: 1. Select an extinguisher, it will then appear in the user's hand. 2. Squeeze the extinguisher handle to use the extinguisher. The scenario will end when the user runs out of
ALWAYS keep a properly maintained and inspected fire extinguisher on hand. Epilog recommends a Halotron fire extinguisher or a multi-purpose dry chemical fire extinguisher. The Halotron extinguishers are more expensive than a dry chemical, but offer certain advantages should you ever need to use an extinguisher.
the heat, smoke, or fire come between you and the evacuation path. Discharge the fire extinguisher with its appropriate range using the P.A.S.S techniques (pull, aim, squeeze, sweep). Back away from an extinguished fire in case it flames up. Evacuate immediately if the fire extinguisher is empty and the fire is not yet out.
Abrasive Water Jet Machining (AWJM) is the non-traditional material removal process. It is an effective machining process for processing a variety of Hard and Brittle Material. And has various unique advantages over the other non-traditional cutting process like high machining versatility, minimum stresses on the work piece, high flexibility no thermal distortion, and small cutting forces .
