What type of air is acceptable to refill SCBA cylinders?

Refilling SCBA cylinders requires compressed air that meets specific standards to ensure the safety and integrity of the breathing apparatus. Compressed air meeting CGA (Compressed Gas Association) specifications is essential because it guarantees the air is free from hazardous contaminants, properly filtered, and at the correct pressures and purity levels. This is crucial for maintaining lung health and safety during emergency situations or hazardous environments.

Using any other source of air, such as a household compressor, can introduce impurities and moisture that could compromise the SCBA’s effectiveness. Air that contains oxygen or is mixed with other gases can also create dangerous conditions, as it may not provide the correct measures for safe inhalation. Therefore, adhering to CGA specifications is critical for ensuring that SCBA users have the proper quality of air needed for safe operation.
