Topic: Basic Firefighting: SCBA Review

Level of Instruction: 3

Time Required: 3 Hours

Materials:

• Personal Protective Clothing

• Personal Alert Safety System (PASS) Device

• Self-Contained Breathing Apparatus

References:

• Essentials of Fire Fighting, 4th ed., International Fire Service Training Association

• NFPA 1500

• 29 CFR 19134

Preparation

Motivation: Instructor should stress the need for safety in all aspects of emergency service duties and impress upon the students the roles of attitude, training, and awareness. Proper knowledge and use of self-contained breathing apparatus is necessary to help provide a safe working environment for the emergency service provider.

Objective (SPO): The student will be able to describe important aspects of safety and demonstrate practical application as it pertains to emergency service provider operations from memory, without assistance, to an accuracy of 70% and the instructor's satisfaction. The student will be able to identify the basic functions and uses of and properly don and doff self-contained breathing apparatus.

Overview: Basic Firefighting: SCBA Review

• Operation, maintenance, inspection, and cleaning

• Donning and doffing procedures and safety check

• Controlled breathing techniques

• Emergency procedures

• Changing cylinders

• Practical exercises

Basic Firefighting: SCBA Review

SPO 1-1 The student will be able to describe important aspects of safety and demonstrate practical application as it pertains to emergency service provider operations from memory, without assistance, to an accuracy of 70% and the instructor's satisfaction. The student will be able to identify the basic functions and uses of and properly don and doff self-contained breathing apparatus.

EO 1-1 For each component of the SCBA, identify its function, safety feature, and limitations.

EO 1-2 Demonstrate and document maintenance for SCBA.

EO 1-3 Demonstrate donning and doffing the SCBA while wearing full protective clothing and ensure that it is ready for safe use (NFPA 1001 (1997) 3-3.1).

EO 1-4 Demonstrate controlled breathing techniques to utilize during work and emergency conditions (NFPA 1001 (1997) 3-3.1).

EO 1-5 Demonstrate proper emergency procedures to use in case the SCBA fails (NFPA 1001 (1997) 3-3.1)

EO 1-6 Demonstrate changing the cylinder on an SCBA assembly (NFPA 1001 (1997) 3-3.1)

EO 1-7 Demonstrate the use of SCBA in the following evolutions (NFPA 1001 (1997) 3-3.1)

• Following a hose line with obstacles and vision obscured.

• Conducting a simulated search of a structure charged with smoke, locating and interrupting utility service, and attacking a simulated fire using a standpipe system.

• Moving in a forward direction and successfully overcoming obstacles to enter and exit a maze.

 

Instructional Guide

I. Open Circuit/Positive Pressure (1-1)

Method of Operation

• Compressed air from cylinder is supplied to wearer

• Inhalation opens valve in regulator

• Regulator allows air to flow to facepiece

• Exhalation closes valve in regulator, stopping flow and opens exhalation valve in facepiece to atmosphere

-------------------------

• Air from cylinder is allowed to pass through regulator. Upon inhalation, pressure is reduced in facepiece. Regulator supplies more air to compensate for pressure drops. Exhalation valve forced closed by spring tension causing slight pressure buildup inside facepiece

• Maintains slightly higher than atmosphere pressure

• Prevents leaks from outside into facepiece

-------------------------

SCBA Components

• Cylinder

        • Types

             • 30 minute high pressure system

                     • Volume - 45 cu. ft. at 4,500 psi

                     • Cylinder is about half the size of a 30 minute low pressure cylinder, providing
