Title: Fire Safety Plan


1
General Fire Safety By Impact fire and Safety
Appliances Pvt. Ltd.
2
Most Common Causes of Fire
  • Faulty or misused electrical equipments
  • Build up of rubbish or waste material (Poor
    Housekeeping)
  • Smoking
  • Cooking
  • Heating appliances placed near Combustible/Flammab
    le materials
  • Unsafe Storage and use of Combustible/Flammable
    materials
  • Unsafe storage and use of hazardous materials
  • Hot process
  • Arson

3
Fire Triangle
  • 1. In order to ignite and burn, a fire required 3
    elements
  • Fuel
  • Heat (a source of ignition)
  • Oxygen
  • 2. Each element should be present in correct
    proportion
  • 3. A fire can be prevented or extinguished by
    reducing anyone of these elements below the
    critical level, i.e.
  • Shutting of gas supply (Starvation)
  • Cooling for fire with water
  • Smothering flames with fire blankets (Suffocation)

4
What is Fuel
  • Anything that burns is a potential fuel for a
    fire
  • Duration of the fire will depend on the amount of
    fuel available

5
What is Heat
  • Must be sufficient to raise the fuel to its
    ignition temperature
  • After fire begins to burn, the source of ignition
    can be removed as combustion process releases
    heat energy to sustain the fire
  • Amount of heat required depends on the
    following-
  • Combustion point of fuel
  • Type of fuel
  • Amount of oxygen available

6
What is Oxygen
  • To sustain a fire, atmosphere only needs to have
    16 oxygen (The air we breathe is around 21)
  • Intensity of a fire depends on the concentration
    of oxygen available
  • Some chemicals releases oxygen when they gets
    heated thus adding to the natural supply

7
Sources of Fuel
  • Combustibles
  • Paper and Cardboard
  • Plastics and Rubber
  • Textiles and Soft furnishings
  • Wooden Items
  • Waste products
  • Flammables
  • Flammable liquid based products
  • Flammable liquids and solvents
  • Flammable chemicals
  • Flammable gases

8
Sources of Ignition
  • Cigarettes, Matches and Lighters
  • Naked Flames
  • Faulty or misused electrical equipments
  • Fixed or Portable Heaters (Electric, Gas,
    Oil-filled)
  • Hot Processes
  • Cooking Equipments
  • Lighting Equipments
  • Obstructions of Equipments Ventilation
  • Arson

9
Sources of Oxygen
  • Main sources is in the air around us
  • In an enclosed building, oxygen is provided by
    natural airflow through doors/windows or
    mechanical air conditioning/ air handling
    systems
  • Further additional sources can be found in -
  • Oxidizing Chemicals
  • Oxygen supplies from cylinders storage and piped
    systems

10
Hazards and Risks
  • Hazards Anything that has the potential to
    cause them
  • Risks The chance of that harm occurring and
    severity

11
Hazards Created by Fire
  • Flames and Heat
  • Smoke and other products of combustion
  • Reduced oxygen
  • Structural damage to a building
  • Collapse of a building
  • Exposed Electrical Cables

12
Heat
  • Intense heat can cause serious injuries/death
  • High temperatures can melt clothing into skin,
    causing severe and deep burns
  • Breathing in superheated air causes rapid and
    severe lung damage followed by unconsciousness
  • Exposure to excessive heat can cause
    physiological effects such as heat stress

13
Smoke and Products of Combustion
  • Incomplete combustion produces a variety of
    by-products, many of which are toxic and/or
    corrosive
  • Smoke is the most cause of death in case of fire
  • Injuries/death due to inhalation
  • Irritation of the eyes can reduce visibility
  • Digestive problems and poisoning if swallowed
  • Respiratory and circulatory systems affected, if
    inhaled
  • Poisoning if absorbed by the skin
  • Many gasses produced by the fire are highly
    toxic, e.g. carbon monoxide

14
Reduced Oxygen
  • Oxygen deficiency can occur in 2 ways
  • Fires consume large quantities of available
    oxygen
  • Fires produces large quantities of other gasses
    that displaces oxygen
  • Low oxygen levels can result in disorientation
    and irrational thinking, which makes escaping
    more difficult
  • At worse, unconsciousness and death can occur
    when the brain gets starved of oxygen

15
Structural Damage and Collapse
  • Heat can have a serious impact on the structure
    of the building
  • Burning
  • Spilling
  • Melting
  • Expansion
  • If a building collapses, the people inside may be
    crushed or injured
  • Partial collapse may obstruct escape routes

16
Electricity
  • Fire can cause damage to electrical cables,
    leading to short circuits or exposing live
    electrical conductors
  • Exposed wires can cause electrocution through
    direct contact or contact with water

17
Fire and Smoke Spread
  • Convection
  • Conduction
  • Radiation
  • Direct Flame Contact

18
Convection
  • Main mode of heat transfer in a developing fire
  • Heat transferred by the movement of warmed
    particles in a liquid or a gas
  • As particles are heated, they becomes lighter and
    less dense than air and this rises in atmosphere
  • Heated molecules eventually cools becomes denser
    and sinks
  • Repeated process results in convection currents

19
Conduction
  • Heat transferred through matter from particle to
    particles
  • Particles in heated substance gain kinetic energy
    and move faster
  • These particles than interacts with others
    particles nearby, transferring heat to them
  • The process continues as thermal energy is
    transferred from hotter parts to cooler parts

20
Radiation
  • Uses electromagnetic waves to transfer heat
  • Heat Transfer by radiation can occur over massive
    distances Radiation is how we receive heat from
    sun
  • Heat radiation can pass through transparent
    barriers such as glass
  • For significant level of heat to be radiated, the
    temperature of the heat source

21
Direct Flame Contact
  • Combustible or flammable materials can come into
    direct contact with flames, and the fire may
    travel along, up or through he material

22
Fire Control Measures
  • Preventative
  • Passive
  • Active
  • Managerial

23
Preventive Control Measures
  • Should always be considered first
  • Better to reduce the risk of fire starting than
    to deal with the consequences

24
Preventing Ignition
  • Adopt safe working practices when undertaking hot
    work
  • Provide safe ways of discarding cigarettes
  • Allow smoking only in designated area and
    prohibit it in all areas of fire risk
  • Limit the use of open flames
  • Use suitable electrical equipments and test it
    regularly
  • Ensure that all electrical equipments are well
    ventilated
  • Control Arson

25
Reducing Risks from Fuel
  • Reduces the amount of flammable material in the
    workplace to the minimum required for the
    operation of the business
  • Where possible replace flammable material with
    less flammable alternatives
  • Follow safe working practices when working with
    flammable substances
  • Ensure Safe storage, transportation and handling
    of flammable materials
  • Ensures that waste products are stored in an
    appropriate place until cleared
  • Ensure that paint, wall coverings, textiles and
    furnishings are fire resistant.

26
Reducing Risks from Oxygen
  • Keep windows and doors closed (Balanced against
    employee comfort)
  • Use compartmentation and self-closing fire doors
  • Close off ventilation systems when not in use
  • Prevent or strictly control oxygen rich
    atmosphere.

27
Passive Control Measures
  • Building features that prevent the spread of
    smoke and heat, e.g.
  • Permanent escape routes
  • Refuges with communication system
  • Fire resistance features, fittings and d├ęcor

28
Active Control Measures
  • Systems/Devices that provide early warning of
    fire, control smoke movement or suppress or
    extinguish a fire in its early stages
  • Require some sort of operational
    (Manual/Automatic, Electrical/Mechanical) to
    perform function. Examples
  • Automatic Fire Detection System
  • Manual Call Points And Alarm System
  • Portable Fire Extinguishers and Fire Blankets
  • Sprinkler Systems

29
Compartmentation
  • Sub-dividing a building into separate fire
    compartments in order to
  • Provide a safe refuge to people within the
    building, where it is not practicable to
    evacuate everyone at once
  • Assist fire- fighting operations
  • Minimize property damage

30
Managerial Control Measures
  • Support and active and passive measures, e.g.
  • Develop Fire Safety procedure
  • Undertake training and fire drills
  • Develop maintenance systems for safety
    equipments/fittings
  • Undertake regular fire safety inspections
  • Require vigilance by those responsible for fire
    safety
  • Use Signage to identify escape routes and high
    risk areas

31
Means of Escape
  • Building features and Fittings that enables
    people to move from a place of potential damage
    to place of ultimate or relative safety in an
    event of fire.
  • Should take in to consideration
  • Time takes to move people
  • Time it takes for a fire to endanger the escape
    route
  • The distance people have to travel to a place of
    safety
  • Features might include
  • Structural protection from a fire spread or
    collapse
  • Fire Resistant paints and textiles
  • Fire doors and self closing devices
  • Signage and emergency lightings
  • Ventilation Control System

32
Fire Door Features
  • Self closing device or door release mechanism
    that operates if the fire alarm gets activated
  • Solid rebate or intumescent strips and cold smoke
    seals to prevent flames and smokes passing
    through the gaps
  • Viewing panels should be fire resistant glass
  • Constructed from or coated with fire resistant
    material
  • Clearly identifiable with appropriate safety
    signage
  • Easy to open
  • Well lit
  • Properly maintained

33
Travel/ Distance Capacity
  • Travel Distance How far people have to travel
    to reach an exit, usually measured to a storey
    exit or another fire compartment or protected
    area
  • Exit Capacity How many people can pass through
    the exit in a given time.

34
Emergency Lighting
  • Used when main power supply is failed
  • Should operate automatically and be sufficiently
    bright to allow people to evacuate the premises
    quickly an safely
  • Degree of illumination depends on nature of
    premises and its occupants
  • Exit Doors and escape routes
  • Intersections of corridors
  • Emergency Exit Signage
  • Stairways
  • Changes in Direction/Floor level
  • Windowless rooms

38
Fire Detection
  • Important to detect the fire as soon as possible
    after it starts and to warn other people in order
    to prompt their evacuation
  • In small premises, fire may be detected by
    building occupants
  • In some premises, fires may be detected
    automatically by devices that reacts to the
    presence of, for example, smoke, heat or carbon
    monoxide gas.

  • Create fine mist that cools flames and prevents
    splashing, then create thick that smothers fat
    and prevent reignition (Starving)
  • Only works with animal fats and vegetable oils

48
Simple Checks
  • Is the extinguisher ready to be picked up?
  • Is the pressure gauge reading is in green zone?
  • Weight has extinguisher been discharged?
  • Are there signs of corrosion/leak/rust?
  • Test engineers label Has the extinguisher been
    serviced in last 12 months?
