The firefighter will demonstrate a general understanding of the various methods of advancing an attack line into a structure and the basic principles of fire attack.
Session Reference: 6
Topic: Firefighter Pre-Basic VI
Level of Instruction:
Time Required: 3 Hours
• One fully equiped pumper
• Structure for use in advancing lines
• Essentials of Fire Fighting, Fourth Edition, IFSTA, Chapters 12 & 13
Objective (SPO): The firefighter will demonstrate a general understanding of the various methods of advancing an attack line into a structure and the basic principles of fire attack.
Overview: Firefighter Pre-Basic VI
• Introduction to Attack Lines
• Advancing Attack Lines
• Fire Attack
Instructors Notes: This lesson should be delivered as a combination of demonstration and student practice with the minimum amount of time spent on lecture. This material is designed to give the student some basic information on attack line operations. It is not intended to replace a Firefighter I program nor make the individuals fully-functional firefighters. It includes some basic information that any new firefighter should know to assist in an exterior mode on the fireground. Instructor should have apparatus and attack hose and nozzles available for display, demonstration, and handling.
Firefighter Pre-Basic VI
SPO 6-1 The firefighter will demonstrate a general understanding of the various methods of advancing an attack line into a structure and the basic principles of fire attack.
EO 6-1 Explain the application and use of attack lines.
EO 6-2 Demonstrate advancing attack lines into a structure.
EO 6-3 Demonstrate a basic knowledge related to the placement of fire streams at structural fires.
I. INTRODUCTION TO ATTACK LINES (6-1)
Use and Application of Attack Lines
• Consist of hoselines of 1-1/2-inch, 1-3/4-inch, 2-inch, and 2-1/2-inch
• Generally pre-connected to the apparatus and equipped with a nozzle
• In lengths of at least 150 feet
Nozzles and Hose Adapters
• Combination nozzle - adjustable patterns from straight stream to wide angle fog; may have adjustable flow by adjustment ring or automatic flow with variable flow based on nozzle pressure - flow from 65 to 350 GPM
• Solid stream nozzle - smooth bore tip for straight stream; may have multiple tips for different flows - flow from 150 to 350 GPM
Attack Line Hose Loads
• Minuteman load - hose load includes a certain amount, generally 100 feet, of shoulder load as part of the overall load; nozzle is positioned in middle of load
• Stack load - hose stacked with ears protruding for ease in pulling; nozzle is on top of load
II. ADVANCING ATTACK LINES (6-2)
NOTE: In order to demonstrate the various methods of pulling hose, the instructor may have to have the hose repacked prior to the pulling demonstrations.
Pulling Attack Lines
• Minuteman load
• Pull shoulder load beginning at nozzle and all hose above it by grabbing nozzle and hose above it and placing it on the shoulder
• Pull hose out of the hosebed so that about four feet is on your shoulder
• Continue moving forward until all the shoulder load has cleared the hosebed
• Turn around and pull the exposed ear so that the remaining hose is removed from the hosebed
• Walk toward the structure while allowing the hose on the ground to stretch out
• Once the hose on the ground has been stretched out, the hose on the shoulder will start stretching out
• Hose remaining on the shoulder should be placed near the entrance to the structure and stretched out to avoid any kinking in the hose
• Stack load
• Pull several layers of hose and the nozzle
• Pull hose out of the hosebed so that about four feet is on the shoulder
