1. HOUSEKEEPING AND FIRE PREVENTION
Bi-Weekly Safety Meeting
October 3, 2013

2. Housekeeping
Both in the field and in the office, effective housekeeping means maintaining a clutter-free environment at all times, not just when the clutter becomes unmanageable and removal becomes unavoidable. It's an essential factor in a good safety program, promoting safety, health, production, and morale.

3. Does your job site look like this?

4. Does your desk look like this?

5. Benefits of Good Housekeeping
Helps to eliminate accidents and fire hazards
Maintains safe, healthy work conditions
Saves time, money, materials, space, and effort
Improves productivity and quality
Boosts morale
Reflects a well-run organization

6. Costs of Poor Housekeeping
Slips, trips, and falls
Fires
Chemical and machine accidents
Injuries from electrical problems
Collisions and falling objects
Health problems

7. Employee Feedback
9/13/13: Clean up as you go is a good practice, so that your work space is not a tripping hazard.
3/4/2013: Time to clean up my office to get rid of old projects papers. Better be careful to avoid paper cuts.
3/7/2013: Ash tray outside rack room was on fire. Notified operations and they put it out.
9/5/2013: Report all spills to 501 on C-1
9/18/2013: Two chair mats were stacked in conference room. Employee stepped on top mat and almost fell. Mats were removed from conference room and individually placed in offices.

8. 2/4/2013: Kitchen near main conference room is dirty, including microwave and refrigerator door. It is embarrassing when clients walk in.
3/1/2013: Stack of napkins sitting on top of the toaster oven in main break room. Fire hazard.
4/10/2013: New installed light has plastic bags covering it. The heat will melt the plastic. Can cause fire.
3/28/2013: Too many computers confined to a small area need to be spread out to avoid a fire hazard.

9. MSP-201, Fire Prevention Program
Mangan employees are not encouraged to fight a fire, no matter how small.
It is not part of any employee’s job description to extinguish a fire
If, however, an employee who has received training on the use of a fire extinguisher chooses to extinguish an incipient fire using one of the portable fire extinguishers located throughout the office area, they can do so.
This is the case as long as such action will not pre-empt the evacuation procedures outlined in Mangan’s Emergency Action Plan and the employee will not lose their means of exit while trying to extinguish the fire.

10. Prequiz: How Much Do You Know?
The same kind of fire extinguisher will put out any type of fire.
You should not try to fight a large, spreading fire with an extinguisher.
To get started and keep burning, a fire needs only two things—fuel and an ignition source.
When using an extinguisher, you should aim the nozzle at the top of the fire. 10

11. How Fires Start and Keep Burning
FUEL
Slide Show Notes
Fire is the result of a chemical combustion reaction. Four things are necessary for a fire to get started and for the chemical reaction to continue—oxygen, fuel, heat, and an uninhibited chain reaction.
Here’s how fire works. There’s plenty of oxygen in the air to support fire. So that’s the first element required for a fire to get started.
Next, some sort of fuel is required, such as wood, paper, or gasoline. But wood, paper, gasoline, or other fuels don’t spontaneously catch fire just because they are surrounded by oxygen. For the chemical combustion reaction to take place, the fuel has to be heated to its ignition temperature by some outside source.
What are some ignition sources?
burning cigarette, a spark, overheated equipment, static electricity, or a chemical reaction.
Once ignited, the heat of the flame keeps the fuel at the ignition temperature, so it will continue to burn as long as there are fuel and oxygen.
This combination of heat, oxygen, and fuel working together creates a chemical chain reaction called combustion.
OXYGEN
HEAT 11

12. Class A Fires Wood Paper Cloth Plastic Garbage
Fires are generally classified according to the type of fuel involved. Class A fires, for example, involve ordinary combustible materials such as:
Wood, pallets, and lumber;
Paper and cardboard;
Cloth;
Plastic and foam; and
Garbage.
Think about your work area.

13. Class B Fires Gasoline Oil Solvents Grease Slide Show Notes
Class B fires involve flammable liquids such as:
Gasoline, kerosene, and other liquid fuels;
Oil and other combustible liquids;
Common solvents such as paint thinners, mineral spirits, and organic solvents found in laboratories; and
Grease that is often found in kitchens.
Are there any flammable liquids in your work area?

14. Class C Fires Appliances Switches Panel boxes Power tools
Slide Show Notes
Class C fires involve energized electrical equipment such as:
Appliances, including stoves, washing machines, and dryers;
Switches, outlets, power cords, and extension cords;
Panel boxes and circuit breakers; and
Power tools, including drills, sanders, grinders, and saws.
Are you aware of all the types of energized electrical equipment in your work area?
Identify the different types of energized electrical equipment in the workplace.

15. Ash (ordinary combustibles) Boils, Bubbles (flammable liquids)
Current (energized electrical equipment)
Type A fires: involves anything that can turn to ASH
Type B fires: involves anything that BOILS or BUBBLES
Type C fires: involves anything with a CURRENT

16. Class D Fires Magnesium Titanium Potassium and sodium
Pyrophoric materials
Slide Show Notes
Class D fires involve combustible metals. For example:
Magnesium metals, chips, or grinding dusts, which can be found in some metal shops.
Titanium metals, chips, or grinding dusts, which can be found in many aerospace sheet metal facilities.
Potassium and sodium, which in their pure elemental forms are soft, ductile, malleable metals that can be easily cut with a knife or drawn into wire. These metals react with air and water, and are usually stored in a material such as mineral oil. Because they react with water, extinguishing a potassium or sodium fire with water could result in an explosion.
Pyrophoric materials are also combustible metals. They are highly reactive substances used in the synthesis of organic chemicals. Special training is required to store and handle these materials safely. Examples include alkyllithiums, alkylmagnesiums, and diphosphine. A Class D fire extinguisher must be on hand when handling these materials. Using the wrong extinguisher could result in a larger fire.
If you work with combustible metals or in a work area where these metals are stored or handled, make sure there are Class D extinguishers available.
Identify any combustible metals in your workplace.

17. Class K Fires Cooking oil Fat Slide Show Notes
The last class of fire is Class K fires, which are kitchen fires. This class of fire involves:
Cooking oil, and
Fat.
These fires generally occur in kitchens at restaurants and other establishments where deep fat fryers are used.

Slide Show Notes
Now, it’s time for an exercise. See if you remember how we’ve defined the different classes of fire by matching the class of fire in the column on the left to the material in the column on the right that fuels the fire.
[PAUSE]
Did you make these matches?
Class A—ordinary combustibles;
Class B—flammable liquids;
Class C—energized electrical equipment;
Class D—combustible metals; and
Class K—cooking oils and fat.
How did you do? Did you correctly match the class of fire to the material? Are you setting goals to help yourself remember the information after you complete the course?

19. Fire Prevention— Housekeeping
Keep your work area clean and organized
Keep dusts away from motors and hot machinery
Dispose of oily or solvent-soaked rags appropriately
Don’t let combustible materials accumulate
Keep exits clear
Maintain access to fire response equipment
Housekeeping plays a critical role in fire prevention. Keeping your workplace clean and organized not only prevents the ignition and spread of a fire, it also helps keep exits clear and fire response equipment accessible.
Keep all dusts under control, particularly around motors and hot machinery.
Dispose of rags contaminated with oils or solvents in appropriate metal containers.
Don’t allow combustible materials such as cardboard, paper, or wood to accumulate.
Keep exits clear.
Keep access to emergency response equipment clear.

20. Extinguishing Fires FUEL CHAIN REACTION OXYGEN HEAT
You must remove one of these:
Heat
Oxygen
Fuel
FUEL
CHAIN REACTION
Slide Show Notes
Fire extinguishers are designed to remove at least one of the three elements of fire so that the fire will die out. In other words, to extinguish a fire, you must remove either:
Heat,
Oxygen, or
Fuel.
The best way to remove heat from an ordinary fire is to dump water on the fire. This cools the fuel to below the ignition point, which interrupts the combustion cycle.
How do we remove the oxygen? you can smother a fire so that it is not exposed to air. One way to smother a fire is to cover it with a heavy blanket. Another way is to dump nonflammable material on it, such as sand, baking soda, or inert gases.
Removing fuel is the most difficult way to extinguish a fire because fuels are usually everywhere. In most cases, the fuel will only be removed once the fire burns it all up.

21. Extinguisher Types A—For combustibles such as trash, wood, or paper
B—For flammable liquids or gases
C—For electrical fires
D—For combustible metals such as magnesium

22. Water Extinguishers Use water on Class A fires ONLY Slide Show Notes
Water extinguishers contain water and compressed gas. They spray a stream of water on the fire. Water extinguishers are rated only for Class A fires—that is, fires caused by ordinary combustibles such as wood, paper, cardboard, plastic, and garbage.
Should you use a Water Extinguisher on a Class B fire? No. Class B fires involve flammable liquids such as oil, gasoline, solvents, and grease. All of these fuels float on water, so they will continue to burn and actually spread out if you try to extinguish them with water. Furthermore, a hot grease fire hit by a spray of cold water will result in the splattering of burning grease, which could spread the fire and injure the person using the extinguisher.
Spraying water on a Class C fire that involves electrical equipment could result in an electrical shock.
The extremely hot temperature of a Class D fire involving combustible metals will break the water molecules down into hydrogen and oxygen molecules that will actually feed, rather than extinguish, the fire.
Remember that all five extinguishers use a significant amount of pressure when activated. Be careful not to point the stream toward anyone.
Do you know where water extinguishers are located in your work area?
Tell trainees where water extinguishers are located in your workplace and show them what the label looks like. 22

23. Dry Chemical Extinguishers
Best all-around choice
Class BC-rated
Class ABC-rated
Dry chemical extinguishers are your best all-around choice for the average industrial, manufacturing, office, or warehouse environment. They have the advantage of leaving a blanket of nonflammable powder on the extinguished material, which reduces the likelihood of reignition.
Class BC-rated dry chemical extinguishers contain either sodium bicarbonate (what’s sodium bicarbonate?), which is normal baking soda, or potassium bicarbonate, which is nearly identical to baking soda, as the extinguishing agent. The propellant, which makes the powder spray out of the extinguisher, is an inert compressed gas.
Class ABC-rated dry chemical extinguishers are the most common. They contain ammonium phosphate as the extinguishing agent and an inert compressed gas as the propellant.
Remember that any fire extinguisher can contain materials that displace oxygen—thus, making it more difficult to breathe. Once an extinguisher has been used, the area should be cleared and ventilated.
Do you know where to locate dry chemical fire extinguishers in your work area? 23

24. Carbon Dioxide (CO2) Extinguishers
Class BC-rated
Good choice for electronics
Must be used at close range
Slide Show Notes
Carbon dioxide, or CO2 extinguishers put out fires by displacing the oxygen near the fire, which smothers the fire. The carbon dioxide also cools down the burning material.
CO2 extinguishers are primarily effective on Class B and C fires. CO2 is not effective on Class A fires and should never be used on Class D fires.
The advantage of CO2 extinguishers is that they do not leave any residue. Because of that, they are a good choice for fires involving computers and other electronics.
The disadvantage of CO2 extinguishers is that the gas disperses quickly, so they are only effective at relatively close range—a distance of 3 to 8 feet from the fire. 24

25. Metal/Sand Extinguishers
Class D-rated
Powdered copper
Sodium chloride
Air-tight crust
Another type of fire extinguisher is the metal/sand extinguisher. These extinguishers are approved for Class D fires involving combustible metals only. 25

26. Other Type of Fire Extinguishers:
Halon Extinguishers
Halotron I Extinguishers
FE-36 Extinguishers
Water Mist Extinguishers

27. Fight-or-Flight Decision
Alarm activated?
Fire department called?
Fire is small and contained?
Smoke avoidable?
When a fire occurs, you have to make a fight-or-flight decision: Will you evacuate or stay and fight the fire with an extinguisher? Only attempt to use an extinguisher if you can say “yes” to every point on this slide and the next slide. If these conditions have not been met, do not fight the fire yourself—evacuate the area.
Here are the conditions under which you may safely use an extinguisher:
The fire alarm has been activated, which means other employees are notified of the fire and are evacuating the building or coming to your aid.
The fire department has been called. Someone has called 911 and is on the line with the dispatcher.
The fire is small, contained, and not spreading beyond its starting point.
The smoke is not bad. You can easily stay low and avoid the smoke while using the fire extinguisher.

28. Fight-or-Flight Decision (cont.)
Exit clear?
Extinguisher nearby?
Trained to use extinguisher?
Slide Show Notes
Here are a few more conditions in which you may safely use an extinguisher:
The nearest exit is clear so that you can easily evacuate if the fire suddenly increases in size. When fighting a fire with an extinguisher, your back should always be toward the exit so that you know you can always escape.
The correct extinguisher for the class of fire is nearby.
And finally, you have been trained to use a fire extinguisher correctly.
Think about your evacuation areas 28

29. How to Use a Fire Extinguisher Effectively
Pull
Aim
Squeeze
Sweep
Slide Show Notes
Even though fire extinguishers come in a number of shapes and sizes, they all operate in a similar manner. To use an extinguisher effectively, remember the PASS system. PASS stands for Pull, Aim, Squeeze, and Sweep.
Here’s how it works.
Pull the pin at the top of the extinguisher. The pin keeps the handle from being accidentally pressed when the extinguisher is not in use.
Aim the nozzle toward the base of the fire. Stand 8 to 10 feet from the fire. Note that some types of extinguishers require you to be closer.
Squeeze the handle level to discharge the extinguisher. When you release the handle lever, the discharge will stop. Keeping the lever squeezed will result in a continuous flow of extinguishing agent. Squeezing and releasing the level will result in short bursts of extinguishing agent.
Sweep the nozzle back and forth toward the base of the fire as you squeeze the handle lever. After the fire appears to be out, watch it carefully, since it might reignite. p a s s

30. Extinguisher Inspections
Check for:
Pressure
Pin
Damage
We have a service that comes out annually to inspect our fire extinguishers (every March), however if you notice any visual defects on them or if you notice that any are missing or access to them has been blocked, please notify safety and we will take action to make any necessary repairs, corrections or to replace any of them.

32. 50 ft 75 ft 50-75 ft Location and Signs 75 ft—Class A 50 ft—Class B
50-75 ft—Class C
75 ft—Class D
Extinguishers must be readily accessible and clearly marked. They cannot be blocked by equipment or materials, as we’ve said, and they must be mounted so that they can be easily removed in an emergency. The location of extinguishers must be identified with highly visible signs that point toward the extinguisher and can be seen from all over the work area.
Class A extinguishers cannot be located more than 75 feet from any point in the workplace where ordinary combustibles might be involved in a fire. This measurement includes walking down aisles, around equipment, or around materials that might be in the way.
Class B extinguishers must be located within 50 feet of areas where flammable liquids might be involved in a fire.
Class C extinguishers, used for electrical fires, must be distributed in the same pattern as Class A and Class B extinguishers, which is 50 to 75 feet from the point of use.
Travel distance between Class D extinguishers and work areas with combustible metals must be no more than 75 feet.
