Rescue Priorities
 Most Severely Threatened Victims
 Largest Groups of Victims
 Remainder of People in Fire Area
 Victims in Exposed Areas
 Position Aerial at Corner of Bldg., When Possible
Window Rescue
 Perpendicular to Bldg., If Possible
 Don't Block Opening
 Platform
 Top of Basket Even with Sill
 Approach From Side or Top
Victim Removal on Ladder
 Capable Adults
 F/F to Act as Guide for Descent
 Injured Adults
 Over the Shoulder Carry - One F/F to Assist
 Infant
One Arm Carry
Victim Removal by Stokes
 Down Ladder
 Top Guide Rope
 Rope Lowering
 Guy Lines
 Rope Through Rungs
 Lower Ladder
 Stokes Mount on Platform
Aerial used for Exposure Protection
 Direct Application of Stream Onto Exposure
 Stream into Thermal Column
 Eliminate Brands
 Wide Sweeping Motion of Stream
 Don't Break Windows
Fire Attack
 Offensive
 Straight Stream Into Structure
 Defensive
 External
 Never when F/F or Victims Are In Building
 Stream Elevation
 Maximum of 80% of Ladder Length
Fog Stream Advantages
 Greater Heat Absorption
 Steam
 Wider Area of Coverage
 Close-up Offensive Attack
 Exposure Protection
 Siphon Ventilation
Disadvantages
 Short Reach and Penetration
 Affected by Wind
 Fire
 Atmosphere
Detachable Water Pipe
 Set Pattern on Ground
 Clamp Nozzle to Top Two Rungs
 Secure with Safety Rope
 Attach Guide Ropes if Applicable
Detachable Water Pipe
 Attach Supply Line
 77m (3")
 Hose Straps
 Attach Siamese and Gate
Master Stream
 Climb ladder as per safe ladder practices
 Foot Pads Down and Locked
 Fasten Safety Belt
Master Stream
 Create the Fire Stream as Per Officer’s Orders
 − Type of Stream
 − Direction
 − Purpose
 • Avoid Electrical Wires with Stream

Factors affecting aerial
performance Heat
 Discoloration
 Deformed Welds
 Improper operation of any part
 Paint Blister
 Heat Labels
 Pressure relief valve on hydraulics
 Warm to the touch
Mechanical Failure Signs
 Leaking fuel
 Leaking hydraulic fluid
 Cooling system leak
 Motor oil leak
 Overheating of components
 Vibrations and noises
 Stress cracks
Cold Temperatures
 Slower operation due to thick hydraulic fluid
 Steel affected ( minimized shock load)
 Ice forming on ladder ( increased weight)
 Frozen hydraulic lines
 Won’t retract
 Freezing runoff ( truck may slide downhill
 Drain water pipe as soon as completed with it
