           • Direction to show the routhe to exit and enter building
         • Escape plans
           • Plan that shows which routes to follow in case emergency and should available in each building
         • Stairs

         • Fire door
           • Easily accessible and must unlocked
   • ACTIVE SYSTEM
     • Fight fire directly and can works manually or automatically
       • FIRE EXTINGUISHER
         • Standard equipments in buildings
         • Advantages
           • Appropriate for various types of fire
           • Not endanger user
           • Easy to use, reliable and effective
         • Type of extinguisher
         • Colour coding
         • Maintenance
           • At least once a month inspect extinguisher
             • Ensure that there is no blockage, nozzle or other part are not obstructed, pin and tamper seal are intact

         • Control fire at an early stage by spraying water and act automatically
           • System consists of automatic sprinklers attached to piping system that connected with water supply and water discharges immediately from sprinklers
             • Installations to commercial and industrial may follow these type
               • Wet system
               • Dry system

               • Pre-action system
               • Recycling pre-action system
               • Cycling wet system
       • WET AND DRY RISER
         • Wet riser is fire hydrant in building for use for firefighter. Required for building with heights more than 30.5m
         • Dry riser is a pipe mounted vertical column from ground floor to top floor. Building over 60 feet and not more than 100 feet high should fit
       • HOSE REEL
         • Manual system to give early aid and suitable for small fire. Use piping system that connect to two pumps

4. ELEMENTS IN SYSTEM

   • System control unit
     • Primary electrical supply
       • Secondary power supply
         • Alarm activation devices
           • Alarm indication devices
             • Remote indication on building monitoring system
               • Control relay via a building management system to effect fire extinguisher and ventilation smoke control actuators
