3 3 Key Terms Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

4 4 Key Terms Flash Point –The lowest temperature at which a liquid gives off enough vapors to ignite if it comes in contact with an ignition source, such as a spark or flame Flammable –A liquid is flammable if it has a flash point of less than 100 degrees Fahrenheit Combustible –A liquid is combustible if its flash point is 100 degrees Fahrenheit or higher Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

5 5 Key Terms Pyrophoric –A type of gas or substance that will ignite when exposed to air Spontaneous Combustion –The process of a substance catching fire as a result of heat generated by an internal chemical action Flashback –The rapid travel of a spreading gas from a source of ignition back to the point at which it originated –Flashback occurs when a gas or vapor heavier than air travels at a low level to an ignition source Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

6 6 Key Terms Lower Explosive Limit –The minimum concentration of a flammable substance in the atmosphere that will ignite Upper Explosive Limit –The maximum concentration of a flammable substance in the atmosphere that will ignite Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

7 7 The Fire Triangle Once the four requirements are met and a fire has started, it continues to burn due to complex chain reactions between the fuel and oxygen The relationship between fuel, heat, and oxygen is best described by a three-sided diagram known as the Fire Triangle Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

8 8 The Fire Triangle Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

9 9 Air, Fuel, and Heat To START, a fire must be supplied with: –Oxygen Catalyst that sustains combustion Can come from air or fuel itself –Heat Raises material to ignition temperature –Fuel Supports combustion The chemical reaction when these elements interact results in a fire Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

10 10 The Fire Tetrahedron ALL fires require four basic elements: Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973 OxygenFuelHeat Chemical Reaction

11 11 Extinguishing a Fire One of the basic elements must be REMOVED to extinguish a fire: –Fuel – Cool to below the temperature at which it will burn (kindling temperature) –Oxygen – Cut off supply (smothering the fire) –Chemical Reactions – Interrupt the chain reactions that keep the fire going by reducing or eliminating the heat or ignition source (primary extinguishment method when using a dry-chemical fire extinguisher) Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

12 12 Types of Fires Fires are classified by the type of fuel they burn – the five classes of fire are known as: –A–A –B–B –C–C –D–D –K–K Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

13 13 Class A Fires Ordinary Combustibles: –Wood –Paper –Cloth –Plastic –Trash Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

14 14 Class B Fires Flammable Liquids: –Gasoline –Oil –Grease –Paint Flammable Gases: –Propane –Butane Does NOT include fires involving cooking oils or grease Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

15 15 Class C Fires Energized Electrical Equipment: –Motors –Switchgears –Transformers –Appliances –Heaters Remove the power and a Class C fire becomes one of the other classes of fire Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

16 16 Class D Fires Combustible Metals: –Potassium –Sodium –Aluminum –Magnesium Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

17 17 Class K Fires Cooking Oils and Greases: –Animal fats –Vegetable fats Typically found in commercial kitchens Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

18 18 Types of Fire Extinguishers Water CO 2 Foam Halon Powder Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

19 19 Dry Powder Fire Extinguishers Two types: –Copper –Sodium Chloride Extinguish the fire by separating the fuel from the oxygen element or by removing the heat elements of the fire triangle For use on Class D fires ONLY –Remember Class D fires have extreme heat and toxic fumes Ineffective on all other classes of fire Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

20 20 Combination Fire Extinguishers Combination ABC or BC extinguishers are used when a fire involves one or more of the three types of fires Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973 ABC

21 21 Tips for Extinguishing a Fire Important: Aiming an extinguisher at a single point at the edge, 2-4 outside edge, of the fire will not work; the fire will simply spread around the spot that has been put out Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

23 23 Operating Fire Extinguishers Four basic steps: –P ull the pin –A im low –S queeze the lever (trigger) –S weep side to side Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

24 24 Operating Fire Extinguishers After the fire appears to be extinguished, watch the fire area. Dont waste expellant Keep in mind that the discharge time of a portable extinguisher can be very short If the fire cannot be completely extinguished, leave the area immediately and wait for the fire department to arrive Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

25 25 Operating Portable Fire Extinguishers NFPA recommends that when a small fire breaks out, someone should call the fire department immediately A portable extinguisher may not be able to put out the fire, and waiting to call the fire department could waste valuable time The fire department should inspect all fires even after they have been extinguished Because it is standard procedure for most fire departments to respond to any call by dispatching a fully-staffed fire truck to the scene, many people feel this step is unnecessary. But from the fire professionals point of view, it is better to prevent a small fire from re-igniting than to deal with a full- blown fire emergency Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

26 26 Size of an Extinguisher NEVER fight a fire without the proper type and size of fire extinguisher: 2 lb 5 lb 10 lb 20 lb 40 lb Or Bigger Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

27 27 REMEMBER! Fires have many possible characteristics depending on location and fuel All fires are unpredictable and should be approached with caution and respect Keep in mind that unconfined or uncontrolled fires spread, advancing outward in all directions from where they started toward new fuel –This is an important concept to remember because to put out even a small fire it is necessary to work from the outside in Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

29 29 Tips for Extinguishing a Fire Most Class A fires start small - be careful not to make them bigger! Begin fighting the fire from a safe distance of at least six feet or until you feel heat. Avoid direct exposure to smoke as much as possible Stay up wind. Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

30 30 Tips for Extinguishing a Fire Aim the extinguisher low at the base of the fire, not at the center of the blaze –Fires tend to be coolest at their edges and therefore are easier to extinguish there Sweeping the extinguishing agent from side to side will extinguish the edge of the fire evenly - like using a hose to wash dirt off a sidewalk As the edge of the fire recedes, it is alright to move closer to the fire area Always keep in mind that the capacity of a portable fire extinguisher is limited, so work to extinguish the fire as quickly and safely as possible. Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

31 31 REMEMBER! It is very important to use the proper extinguisher for the type of fuel present! Using the incorrect agent can allow the fire to re- ignite after seemingly being extinguished successfully Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

32 32 Fire Rules FIRES ARE VERY DANGEROUS! –Pull the fire alarm –Call 911 –Assist anyone in danger Be certain that you will not endanger yourself or others when attempting to put out a fire Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

33 33 Fire Rules NEVER fight a fire if you dont know whats burning –If you don't know whats burning, you don't know what type of extinguisher to use –Even if you have an ABC extinguisher, there may be something in the fire that will explode or produce highly toxic smoke Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

34 34 Fire Rules NEVER fight a fire if its spreading rapidly beyond the spot where it started The time to use an extinguisher is in the beginning stages of a fire –If the fire is already spreading quickly, it is best to simply evacuate the building, closing doors and windows behind you as you leave Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

35 35 Fire Rules NEVER fight a fire if you don't have adequate or appropriate equipment –If you don't have the correct type or large enough extinguisher, it is best not to try to fight the fire NEVER fight a fire if you might inhale toxic smoke –If the fire is producing large amounts of smoke that you would have to breathe in order to fight it, it is best not to try –Gases from man-made materials can be fatal, even in very small amounts Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

36 36 Fire Rules NEVER fight a fire if your instincts tell you not to –If you are uncomfortable with the situation for any reason, just let the fire department do their job ALWAYS position yourself with an exit or means of escape at your back before you attempt to use an extinguisher to put out a fire –In case the extinguisher malfunctions or something unexpected happens, you need to be able to get out quickly –You don't want to become trapped –Just remember, always keep an exit at your back or back to the wind Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973

37 37 Important Reminders Thermal decomposition of fire extinguisher agents: –ABC dry chemical (ammonium phosphate) is the most common extinguisher Contains agents of ammonia, carbon monoxide, and oxides of nitrogen –Carbon Dioxide Do not use in confined areas as this gas will displace the oxygen in the air and will cause asphyxiation –Halon 1211 Halon fire extinguishers should not be used in confined areas or small rooms with poor ventilation will cause asphyxiation –Smoke from fires Can cause asphyxiation, respiratory problems, and may contain chemical contents that are toxic –Rekindling of fires All fires must be watched closely since rekindling is always a possibility Safety Counselling, Inc. Providing creative, pragmatic solutions to business safety since 1973
