Checklist for self-contained breathing apparatus (SCBA)

• Inspect the SCBA unit before each use. Test and clean after each use.
• Inspect the equipment designated for "emergency use" at least monthly and after each use.
• Follow the manufacturer's instructions and Standard Z94.4-02 for care and maintenance.
• Permit only trained, manufacturer-certified personnel to maintain SCBA.
• Do not mix parts from different manufacturers.
• Maintain a complete record for each SCBA facepiece and cylinder.

Facepiece

• Disconnect the facepiece from the breathing apparatus. Wash alone in warm (49-60ºC or 120-140ºF) soapy water using a mild dish detergent.
• Rinse the water through the facepiece by placing the palm of the hand over the breathing tube connector on the exhalation-valve body.
• Remove excess water with a paper towel or lint-free cloth.
• Allow to air dry.
• Sanitize according to the manufacturer's instructions.
• Check for tears in the rubber.
• Check head strap for deterioration.
• Examine lenses for cracks, excessive scratching or other deformities.
• Check rings and clamps securing the lens for bends or bulges in the metal.
• Check the exhalation valve to ensure that it is properly located and that the valve cover is in place.
• Test the exhalation valve. Block the air intake opening and exhale gently. If the exhalation valve is not working properly, a heavy blow-by will be felt at the temples. Inhale and a partial vacuum will be formed.
• Do not mix demand and pressure-demand facepieces and regulators.

Regulator

• Check the regulator, breathing-tube threads, pressure gauge, and bypass and mainline valves for impact damage.
• Store with the cylinder valve completely closed.
• Bleed off air remaining in the regulator after each use, following manufacturer's instructions.

Breathing tube

• Stretch the breathing tube and check for cracks, tears and punctures.
• Check gaskets.
• Check clamps and rings to ensure that they are tight, properly located, not dented and not excessively corroded.
• Wash the breathing tube separately and allow to air dry. If it is permanently attached to the facepiece, allow the breathing tube to dry for several days before using.

High-pressure hose

• Check the hose for cuts, bubbles and abrasions.
• Check the fitting between the high-pressure hose and the regulator for damage.

Audible alarm

• Check the audible alarm for damage.
• Clean bells or whistles.
• Ensure that the alarm is working. If the alarm does not go off when the pressure reaches 20-25% of service time, the unit is defective. Remove the unit from service.

Backpack

• Inspect the straps of the backpack for excessive wear, broken stitching, and damaged or missing hardware.

Cylinder

• Ensure cylinders are hydrostatically tested as set out in Standard Z94.4-02, "Selection, Care and Use of Respirators".
• Inspect for cuts or gouges that can cause the unraveling of the composite fibers of the cylinder overwrap.
• Check unwrapped cylinders for impact damage.
• Check for evidence of exposure to heat. Look for discoloured paint or melted gauge lenses.
• Ensure air meets air quality set out in Standard Z180.1-00, "Compressed Breathing Air and Systems".

Cleaning the rest of the unit

• Remove backpack, cylinder and regulator assembly.
• Clean with water, or soapy water.
• Wipe the regulator, high-pressure hose, audible alarm, air cylinder, backpack and harness with a damp cloth.
• Dry with a cloth.
