Life SafetyThe primary goal of fire safety efforts is to protect building

occupants from injury and to prevent loss of life.

Property ProtectionThe secondary goal of fire safety is to prevent property

damage.

Protection of OperationsBy preventing fires and limiting damage we can assure that

work operations will continue.

What is a Fire

Fire is a chain of chemical reaction involving rapid oxidation or burning of a fuel, which produce smoke, heat and flame.

•Fuel

•Oxygen

•Temperature

COMMON CAUSES OF FIRE ACCIDENT Smoking Electric short circuiting Over heating of electric appliances. Over heating of engine or machine. Over heating of oil. Heater or coal burner Matches Spark of oven Sprit lamp Self created fire Friction or resistance High temperature in summer season

17

Special Causes of Fire

• Dust Explosion• Gas and Vapor Explosion• Chemical Reactions• Seasonal Changes• Lightening • Etc.

18

Basic Principles of Fire Prevention

• Prevention of the starting of fire.• Prevention of the spreading of fire.• Prevention of water damage.

19

Prevention of Starting of Fire

• The premises, machines and house-hold articles to be kept neat and clean.

• Sufficient space in between the buildings.• Proper Storage (in godowns)• Careful about fire works.• Periodic inspection of electrical wiring.• No Smoking notices.

20

Prevention of Spreading of Fire

• Firefighting Training for all.• First Aid Firefighting Equipment.• Provision of adequate water supply.• Removal of combustible material from room

and attics.• Fire Receptivity.• Efficient Firefighting Service.

21

Prevention of Water Damage.

• It is job of the professional firefighters to see that less water damage is caused while fighting a fire.

22

FIRE EXTINGUISHER

AN INSTRUMENT USED TO EXTINGUISH THE FIRE IS KNOWN AS FIRE EXTINGUISHER.

23

Standards for portable fire extinguishers

• OSHA-29 CFR 1910.157 - Portable Fire Extinguishers.

• NFPA-10

• Civil Defense Of Pakistan

WATER FIRE EXTINGUISHER

25

Common Fire Extinguishing Agents Water

Advantages:

Removes heat Effective on Class A fires Inexpensive Plentiful Non-toxic

Disadvantages:

Conducts electricity May spread Class B fires Freezes in cold climates May carry pollutants as

run-off water

26

FOAM FIRE EXTINGUISHER

29

Common Fire Extinguishing Agents Dry Chemical

Advantage:• Interrupts chemical reactions• Sodium bicarbonate (baking soda)• Very effective on Class B

and C fires• Not considered toxic

Disadvantage:• Leaves a residue• Obscures vision• Not good on deep-seated fires• Nozzle pressure may cause

burning liquids to splash

30

Common Fire Extinguishing Agents Multipurpose Dry Chemical

Advantages:• Interrupts chemical

reactions• Ammonium phosphate• Effective on Class A, B, and

C fires• Non-conductive

• Disadvantages:• Obscures vision• More irritating than

ordinary dry chemical• Nozzle pressure may

cause• burning liquids to splash Create a layer on

components

31

CO2 FIRE EXTINGUISHER

32

Common Fire Extinguishing Agents Carbon Dioxide (CO2)

Advantage:

• Reduces oxygen to less than 15%.• Effective on Class B and C fires.• No residue.• Relatively inert.

Disadvantage:

• Generally >35% concentration needed • Toxic to humans at >4% by volume• Not the best agent for smoldering fires • Dissipates rapidly - allows reflash

35

Appropriate use of extinguishers

• You can fight the fire with your back toward an escape route

• The extinguisher matches the fire type

• The extinguisher works effectively

36

Appropriate use of extinguishers

• You are properly trained in the use of the extinguisher

• You are confident you can put the fire out

2c

37

Appropriate use of extinguishers

• The fire is large and has grown beyond its original confined space

• Your escape path is threatened

• You are not sure if you have the correct type of fire extinguisher

38

Personal hazards• Smoke and noxious fumes

• Smoke and fumes cause unconsciousness

• Death may result

When not to fight a fire?

Never fight a fire: • If the fire is spreading beyond the spot where it started

• If you can't fight the fire with your back to an escape exit

• If the fire can block your only escape

• If you don't have adequate fire-fighting equipment

44

How to create an Emergency Action Plan?

• Objective• Information and communication• Evacuation• Emergency Equipment• workstations of the disabled workers • Emergency Action Leaders and Teams• Emergency Action Plan Locations• Training and Drills

45

How to evacuate a burning building?• should not lock the door, just close it

• Proceed to the exit.• NEVER, NEVER use elevators.• Stay low, crawl if necessary.• Once in the stairwell, Never go up.• Report to a predetermined area. • when the evacuation alarm sounds, “EVERYONE MUST LEAVE THE BUILDING”

Assembly Point # 1

46

What to do if trapped in a burning building?• Never open a closed door without feeling it first • If the door is hot, try another exit • use wet towels to seal the space under the door and prevent the

entry of smoke • If trapped, look for a nearby phone and call the fire department • If on an upper floor and your window is of a type that CANNOT

be opened, DON'T break it out- you'll be raining glass down on rescuers and people exiting the building

• If you can't contact the fire department by phone, wave for attention at the window. Don't panic.

48

What to do if someone catches fire?

If a co-worker catches on fire, smother flames by grabbing a blanket or rug and wrapping them up in it. That could save them from serious burns or even death.

49

What to do if you catch a fire?

If you should catch on fire:

STOP - where you are

DROP - to the floor

ROLL - around on the floor

This will smother the flames, possibly saving your life.
