OBJECTIVES

The students will:

  • Identify the principles of water supply and tactics for establishing water supplies using municipal sources, static sources, and portable sources.
  • Identify the principles and tactics to achieve salvage.
  • Explain the correct procedures and select the appropriate size hoselines for attaching to a fire department connection.
objectives cont d
OBJECTIVES (cont'd)
  • Describe the procedures for deployment of a hoseline from a standpipe system.

WHAT NEEDS TO BE DONE?INCIDENT STRATEGY(IES)
  • Exposure protection
  • Confinement/Extinguishment
  • Ventilation
  • Salvage
how are you going to do it incident tactics
HOW ARE YOU GOING TO DO IT?INCIDENT TACTICS
  • Exposure protection

– Deploy large diameter hoseline support for water supply

– Deploy one 1-3/4-inch hoseline to Side A third floor for exposure protection

  • Confinement/Extinguishment

– Deploy one 2-1/2-inch hoseline to Side A second floor for confinement/extinguishment

– Deploy one 1-3/4-inch hoseline to second floor Side A for backup hoseline support

  • Ventilation

– Vent roof apertures of fire building

– Horizontal ventilation all floors

  • Salvage

– Deploy salvage covers to protect contents

– Limit water application where possible

implement the water supply action plan
IMPLEMENT THE WATER SUPPLY ACTION PLAN

Communicate assignments clearly to all resources operating on the incident
