Fire fighting passive system

  1. 1. FIRE FIGHTING (PART 1) QUS 3206/MDM NURUL AINI
  2. 2. Why is this happen ?? Did you know: nearly 80% of fire deaths are due to smoke? What did you do if Fire started ??
  3. 3. FIRE ELEMENTS
  4. 4. FIRE CAUSES  Use combustible materials in the building.  Negligence in the use of electrical appliances and damaged hardware  Imperfect electrical wiring  Negligence on the use of mosquito coils, gas stove and fuel flammable.
  5. 5. FIRE SPREADING FACTORS The surface of material Heat transfer rate Wind direction Air moisture
  6. 6. BASIC PRINCIPLE OF FIRE FIGHTING TECHNIQUE EXCLUDE THE OXYGEN FUEL SEPARATION REDUCE THE HEAT fuel
  7. 7. FIRE FIGHTING SYSTEM ACTIVE PASSIVE
  8. 8. PASSIVE FIRE FIGHTING SYSTEM  Definition - structural elements of the building that is capable of performing his duties without assistance / require assistance to curb / restrict the spread of smoke into the building during a fire.  Types of Passive System : 1- Emergency exit 2- Compartmentation 3- Construction material
  9. 9. 1- ESCAPE ROUTE  Permanent structures that allow occupants to escape / fire escape to safety on their own without any help.  It is important to provide openings so that smoke is displaced from the escape routes to the outside air. LOW RISE BUILDING
  10. 10. Horizontal Exit Vertical Exit Final Exit / Assembly Point 1- ESCAPE ROUTE (HIGH RISE BUILDING)
  11. 11. Horizontal Vertical Final
  12. 12. 2- COMPARTMENTATION  The division / separation wall and floor in a building, including roof box for multistoried buildings / terrace.  2 methods : Vertical & Horizontal  Purpose a- to contain, control, reduce, restrict and delay fire spreading, smoke and heat during a fire. b- embankment to firefighters against fire c- protection to building occupants during rescue themselves d- separate the high risk area
  13. 13. 2- COMPARTMENTATION (TYPES) PARTY WALL FIRE RATED DOOR FIRE DAMPER
  14. 14. CAN YOU TELL WHAT THE STORY OF THIS PICTURE ?
  15. 15. DISCUSSION 1  Discuss the types of compartmentation that been used for building by providing this matters : 1- Definition 2- Objective 3- Construction ( sketches is needed)  Duration : 45 minutes
  16. 16. 3- CONSTRUCTION MATERIAL  WOOD - has a low thermal conductivity and fire delay depends on the type of wood  BRICK – low thermal conductivity ; almost reach the level of fire proof  CONCRETE - expanding at a rapid rate between 400-500 º C ; it will collapse during when comes to water  STONE – good thermal insulation  GLASS - are more resistant to fire if installed wire mash  BUILDING BOARD -fire resistance force depends on the thickness & installation.
