Confined Space Breathing Apparatus Pre-Use Checks
Before entering a confined space, breathing apparatus must be inspected and tested to ensure it will perform correctly under pressure. A daily pre-use check helps identify wear, damage, or faults that could compromise respiratory protection in a hazardous environment.
This video demonstrates a full general inspection of a self-contained breathing apparatus set, carried out before use.

Pre-use checks confirm that breathing apparatus is safe, serviceable, and suitable for the task ahead. Confined spaces often contain oxygen-deficient or contaminated atmospheres, leaving no margin for equipment failure.
A thorough inspection ensures:
- Air delivery systems are functioning correctly
- Cylinders contain sufficient breathable air
- Seals, valves, and alarms operate as designed
- Any defects are identified before entry
Skipping these checks increases the risk of exposure, equipment failure, and emergency situations underground or enclosed spaces.
Practical Steps / Key Takeaways
- Visually inspect the harness, backplate, webbing, buckles, and attachment points
- Check high- and low-pressure hoses for cuts, abrasion, or damage
- Inspect the demand valve, O-rings, airflow button, and shut-off function
- Check the face mask visor, seals, straps, and inhalation/exhalation valves
- Confirm the cylinder contains breathing air and is within test date
- Verify cylinder pressure and perform a high-pressure leak test
- Test the low-pressure warning whistle
- Carry out face fit, breathing, and positive pressure checks
- Drain down the system and complete the logbook
Each step confirms the set is ready for safe use.
Breathing apparatus checks are a critical safety control, not a tick-box exercise. Our confined space training teaches teams how to identify faults early, understand acceptable limits, and build confidence in their equipment before entering risk areas.
Consistent checks support safer teams, better decisions, and stronger confined space procedures.
