Flow Path?
movement of HEAT/SMOKE from HIGHER pressure to LOWER PRESSURE…via doors, window, openings and ROOF STRUCTURES
-SEVERAL flow paths
Heat Release Rate:
rate at which energy is generated by the burning of a fuel and oxygen mixture
VEIS?
vent, enter ISOLATE search
- approved tactic when entering through DOOR/WINDOW
- priority upon entering via WINDOW, is to CLOSE DOOR and isolate are being searched from the fire area
- when entering via DOORWAY, control unit CHARGED HOSELINE is advancing on the fire

Ventilation ?
controlled coordinated removal of heat and ,smoke from structure, replacing with escaping gas
bi directional…HEAT AND SMOKE EXHAUSTING FROM TOP and air flowing in towards the fire at BOTTOM
Ventilation Profile should be ?
UPWARDS AND OUTWARDS
SYNTHETIC MATERIALS have a higher?
HEAT RELEASE RATE
- GIVE OFF MORE HEAT QUICKLY than ordinary combustibles , leading to more rapid and sudden change in the fire environment
- fires today develop faster and produce thick black smoke ,,, reducing visibility
-TIC is EXTREMELY IMPORTANT
MODERN content quickly becomes VENTILATION____?
LIMITED

Primary Search>
IMMEDIATE search for LIFE
- RAPID/THOROUGH/Systematic
- quickly with DUE REGARD FOR PERSONAL SAFETY

- 2nd due truck primary on floors above
1st arriving company:
- LOCATE FIRE
- CONTROL DOOR to apt. or area, any other ventilation points
- COMMUNICATE fire location to Engine and IC
- determine if conditions are tenable to support life:
a. entry can be made and search without hoseline…LOCATE/CONFINE FIRE AREA and THEN START SEARCH FROM THIS POINT
b. UNTENABLE…move in BEHIND ENGINE COMPANY and search behind hoseline
Search for LIFE in the areas adjacent to or above the fire area/floor should start IMMEDIATELY upon entering the area….
followed by searching for the extension of fire…any EXTENSION REPORTED TO IC, IMMEDIATELY
Primary search of ELEVATORS conducted?
EARLY into operation
Secondary Search?
THOROUGH/PAINSTAKINGLY COMPLETE SEARCH FOR LIFE OF ALL AREA that required PRIMARY SEARCH
-include ENTIRE OUTSIDE PERIMETER OF BUILDING/ALL SHAFTS, BASEMENTS, CELLAR, ELEVATOR, ROOFS, ETC
TIME IS NOT As important , as ACCURACY.
Secondary search completed ?
BEFORE EXTENSIVE OVERHAULING of fire area is attempted
DIFFERENT COMPANY, other than company that performed PRIMARY SEARCH
