SCBA Primary Screen Overview

Primary Screen Information

• Displays critical information for the user, including a calculated remaining service time for SCBA.
• Countdown timer indicates the estimated rated service pressure until it reaches 35% remaining.
• Actual remaining time may be less than displayed due to variations in breathing rates.
• Displays time is based on the average breathing rate over the last three minutes.
• Increases in breathing rate can significantly reduce available time.

SCBA Unit Identifier

• Each SCBA is equipped with a corresponding unit identifier for quick visual identification.
• The identifier is secured to the carrier band of the apparatus.

Facepiece Cleaning Protocol

• Remove the facepiece-mounted regulator for cleaning.
• Prepare Confidence Plus Germicidal Cleaner solution as per label instructions.
• Submerge the facepiece in the cleaner for at least 30 seconds.
• Use a soft brush or sponge for cleaning; rinse thoroughly in clean water under 110°F.
• Clean the pressure-demand exhalation valve by flushing it with clean water using a blunt object.
• Verify proper operation of the exhalation valve and ensure no moisture remains before returning to service.
• Conduct a negative pressure seal test before using the facepiece again.

Harness and Cylinder Cleaning

• For heavily soiled SCBA, use a mild soap solution with a sponge or a soft/medium bristle brush.
• Cover the regulator outlet to protect from water, dirt, or debris during cleaning.
• Key components to clean include harness, carrier, cylinder, pressure reducer, control module, and battery module.

Cleaning Considerations

• Avoid substances that can damage SCBA parts: no bleach, alcohol, hydrocarbons, or solvents.
• Do not use radiant heat for drying; pressure washers are also prohibited.
• Ensure components are thoroughly rinsed and dry before returning SCBA to service to prevent freezing.

Maintenance Reporting System

• Maintenance of saws involves a dual reporting system: a Work Order Ticket and an Out of Service Tag.
• Work Order Ticket generated in Vector; a physical out-of-service tag is affixed to the equipment.
• The out-of-service tag requires:
  • Date of reporting
  • Inventory Identification Number (SER.#)
  • Location (Station and Unit)
  • Description of the problem
  • Signature of the person reporting the issue.

This quiz covers the functionality of the primary screen in SCBA systems. Participants will learn about the countdown timer, estimated service pressure, and the implications of breathing rate on remaining air time. Understanding these elements is crucial for effective air management in critical situations.
