Enabling Objectives as listed below:

Evaluation: Each firefighter will be able to describe each feature of the Scott AP50 SCBA and demonstrate its use with 100% efficacy; with further specificity in #21 and #22 below. 

  1. ICS Review (Form and Presentation) – Assign Companies (Tactical worksheets to track Incident Command)
  2. Brief overview of class participants and their experience level with SCBA
  3. Review of existing daily, weekly, monthly function and maintenance checks on existing Survive Air Panthers.  
  4. Introduce expectations of daily function checks as the norm for each firefighter and review the SCBA Function Check Sheet.

  1.  Description of the specific parts of the AP50 SCBA (Cylinder, backpack, high pressure, low pressure, EBSS, Pass, Regulator, batteries, electronics, lights, knobs, adjustments, attachments to Cylinder at valve) and use.  
  2. Cover each light, valve, knob, and attachment and how it is used and in what situations.
  3. Demonstrate how to locate, remove and replace the batteries located in the backpack, PASS, and regulator of the SCBA backpack.  Two 9 volt batteries are required for the backpack, one 9 volt may be required for the PASS, and heads up displays on regulators may require a battery as well.
  4. Describe the PASS system location and parameters for activation and deactivation. 
  5. Describe the EBSS system location and parameters of use as a rescuer and victim.  Handout EBSS checklist for use during practical training.
  6. Describe the Regulator and how it functions on air, attaches to the facepiece, and when doffing to prevent air leaks.  Discuss any issues that may happen needing maintenance. Demonstrate the purge valve on the regulator and describe the uses of the purge valve.
  7. Demonstrate the three main best practices for donning the SCBA backpack (jacket, cross arm, and overhead).
  8. Description of Facepiece (2000, 3000, exhalation, voice emitter, regulator secure, leak check, hairnet and adjustments, and hand out proper donning and doffing checklist).  
  9. Cylinder valves on existing carbon fiber cylinders with eight years life remaining.  (visual and hydro testing requirements discussion) 
  10. Handout the SCBA function check checklist and review each step for what is expected as a normal daily, weekly, and monthly function checks. 
  11. Each firefighter will learn what may happen if the SCBA is not functioning normally, and what steps to take to ensure the airpack is properly marked as “out of service” needing repair.  
  12. Review what constitutes a failure of the airpack and cannot be used for response.
  13. Process for red tagging an airpack for required maintenance, and procedure for reporting an airpack to the proper authority.  (Need Rafael and Roger for defining this process).
  14. Review with students for lessons learned during this class segment and questions.
  15. Evaluation in the form of instructor’s observations of each student’s understanding and use of the Scott AP 50 System as presented and discussed, pending successful experiential and constructive learning environment performance.
  16. Evaluation Phase: Instructors will observe and interact with individual student companies through question and answer summations to ensure each student can describe each component of the Scott AP50 and how it is used or performs with 100% efficacy.
