Rescuer`s SCBA

Do a proper check and wear a Self-Contained Breathing Apparatus (SCBA) to ensure safety and effectiveness in hazardous environments. Here is a step-by-step guide:

SCBA Pre-Use Inspection and Check

1. Visual Inspection:

   • Check the SCBA unit for any visible damage, wear, or cracks, including the harness, straps, and cylinder.
   • Inspect the facepiece for any cracks, tears, or damaged components, including the lens and head straps.
   • Ensure all straps and buckles are intact and functional.

2. Cylinder Check:

   • Verify that the air cylinder is securely connected and fully charged to the appropriate pressure (usually 90% of full capacity).
   • Check the hydrostatic test date on the cylinder. Replace if the cylinder is out of date.
   • Inspect the cylinder valve for proper function.

3. Regulator and Valve Check:

   • Ensure the regulator and valve are clean and free of debris.
   • Check that the hoses are properly connected and free of damage.

4. Battery Check (if applicable):

   • For units with electronic components, verify that the batteries are charged and functioning.

5. Functional Test:

   • Turn on the SCBA unit by opening the cylinder valve fully.
   • Check the air pressure gauge on the cylinder and the remote pressure gauge to ensure they read the same.
   • Perform a regulator and bypass valve test to confirm air flows correctly.

6. Alarm and PASS Device Check:

   • Check the functionality of the Personal Alert Safety System (PASS) device.
   • Ensure the low-air alarm is functional by simulating low air conditions.

7. Communications Equipment (if applicable):

   • Check the operation of any communication equipment attached to the SCBA.

Donning the SCBA

1. Prepare the SCBA:

   • Lay the SCBA on the ground or a stable surface with the straps and harness open and accessible.
   • Ensure the cylinder valve is closed, and all straps are fully extended.

2. Put on the Harness:

   • Lift the SCBA and place your arms through the shoulder straps.
   • Adjust the shoulder straps so the backplate rests comfortably on your back.

3. Secure the Waist Belt:

   • Fasten the waist belt buckle securely and adjust it snugly to your waist.
   • Ensure the waist belt carries the weight of the cylinder.

4. Tighten Shoulder Straps:

   • Pull down on the shoulder straps to adjust the SCBA to fit your body snugly.

5. Facepiece Donning:

   • Position the facepiece on your face, ensuring the chin is securely seated in the chin cup.
   • Pull the head harness over your head and tighten the straps evenly for a snug fit.

6. Check Seal and Function:

   • Perform a positive pressure test by blocking the exhalation valve and exhaling gently; the mask should pressurize.
   • Conduct a negative pressure test by covering the inlet and inhaling; the mask should collapse slightly against your face.

7. Connect the Regulator:

   • Attach the regulator to the facepiece. Confirm it is locked and secure.
   • Open the cylinder valve slowly and fully.

8. Final Adjustments:

   • Check all straps and connections for security and comfort.
   • Ensure the SCBA is functioning properly and all indicators show it is ready for use.

9. Buddy Check:

   • Have another rescuer perform a quick check of your SCBA to confirm everything is secure and functional.

During Use

1. Monitor Air Supply:

   • Regularly check your air supply and gauge readings.
   • Be aware of your surroundings and any changes in breathing resistance or alarms.

2. Communicate:

   • Maintain communication with your team using hand signals or radio communication.

3. Emergency Procedures:

   • In case of any equipment malfunction, immediately communicate with your team and follow emergency procedures for air supply issues or regulator failures.

After Use

1. Proper Removal:

   • Remove the SCBA by reversing the donning procedure.
   • Ensure you are in a safe area with fresh air before removing the facepiece.

2. Post-Use Inspection and Cleaning:

   • Inspect the SCBA for any damage or wear.
   • Clean and sanitize the facepiece and components according to department procedures.

3. Cylinder Replacement and Recharging:

   • Replace the air cylinder with a fully charged one.
   • Ensure the used cylinder is recharged and stored properly.

4. Documentation:

   • Record the use, maintenance, and any issues in the SCBA log or record-keeping system.

By following these steps, rescuer can ensure their SCBA is properly checked, donned, and used, providing essential protection in hazardous environments.
