1. Fire Safety

2. The Stats
•Fire death statistics 1986-95
throughout the united states
–2.1 Million Fires Reported Per Year
–5,100 Average Civilian Deaths
–28,500 Injuries
–9.6 Billion Dollars in Losses

3. Definitions
•Carbon dioxide (co2)
•Combustible
•Combustion
•Conduction
•Convection

4. Definitions
•Fire cause
•Fire prevention code
•Flammable
•Flash point
•Ignition source
•Ignition temperature

5. Combustion
•Chemical reaction between
–Combustible material (fuel)
–Oxygen
–Ignition source
•Rapid oxidation of combustible
material accompanied by a release of
energy in the form of heat and light

6. Types of Heat Energy
•Chemical
–heat of combustion
–spontaneous heating
–heat of decomposition
–heat of solution

7. •Electrical
–Resistance Heating
–Dielectric Heating
–Induction Heating
–Leakage Current Heating
–Heat from Arcing
–Static Electricity Heating
–Heat Generated by Lighting
Types of Heat Energy

8. •Mechanical
–Frictional heat
–Frictional sparks
–Heat of compression
•Nuclear heat energy
–Nuclear Fission and Fusion
Types of Heat Energy

9. Fire Tetrahedron
•Triangle is out…. Tetrahedron is in…
•Consists of 4 Sides
Oxygen
Fuel
Heat Chain of reaction

10. Three Phases of Fire
•Incipient
–Oxygen content in air not reduced
•Hot smoldering
–Flame may cease to exist if area is
airtight
–Burning reduced to glowing embers
–Dense smoke fills the room
•Free-burning

11. Fire Hazards
•Any
–Material
–Condition
–Or act
•That contributes to the start of a fire,
or
•Increases the extent and severity of a
fire

12. 2 Types 0f Fire Hazards
•Common
–Likely to be found in almost all
occupancies
–Not associated with a specific:
•Occupancy
•Process or activity
•Special
–arises from the process or operations
taking place in the space

13. General Fire Safety
•Housekeeping
–Storage & Disposal of Trash & Debris
–Containers -selected by waste type
•general
•smoking materials
•oily rags
•highly combustible materials

14. Waste Containers
•Locate away from
–Heat sources
•Space heaters; Furnaces; Steam pipes
–Flammable & combustible liquids
–Directly under combustible objects
•Exterior cans
–Locate away from buildings so a trash
fire will not spread to the building

15. Flammable Trash Cans
•Dispose of flammable waste in:
–non-combustible container
–with self closing, tight fitting lid
•Oily or Greasy Materials
–store in trash can with
•airtight lids
•supported by legs so the bottom is several
inches off the floor

16. Housekeeping
Outside
•Keep roofs, yards, courts, vacant lots
& open spaces
–Free of wastepaper
–Weeds
–Litter
–Combustible waste & rubbish

17. Types Of Fires
•Class A
–wood, cloth, paper, cardboard
•Class B
–flammable or combustible liquids,
gases
•Class C
–energized electrical equipment
•Class D
–combustible metal

18. Fire Extinguishers
•Ratings
–based on use by untrained operator
–8 inch deep layer of flammable liquid
•Class A
•Class B
•Class C
•Class D

19. Placement
•Readily visible
–Near points of entry & exit
–Protected from vandalism
•Uniformly distributed
–No more than 50 feet travel distance to
fire for class B materials
–No more than 75 feet travel distance to
fire for class A materials

20. •Easily accessible
–Free from blockage
–Near normal paths of travel
–Mounted no more than 5 feet off ground
–Large extinguishers (+40 pounds)
mounted on wheels
Placement

21. Fire Extinguishers
•Inspect monthly -ensure:
–In proper location and it is accessible
–Discharge nozzle or horn is not obstructed,
cracked or dirty
–Operating instructions on the nameplate are
legible
–Lock pins and tamper seals are in place
–Extinguisher is full and ready for use
–Extinguisher has an inspection tag
