What type of cylinders is housed in the Ready Rack Cylinder Storage System?

The Ready Rack Cylinder Storage System is specifically designed to accommodate 45-minute cylinders. These cylinders are commonly used by firefighters during operations to provide a breathable air supply while they are working in hazardous environments. A 45-minute cylinder strikes a balance between capacity and weight, enabling firefighters to carry them without excessive fatigue while ensuring they have enough air for extended operations.

The choice of 45-minute cylinders in this storage system also aligns with the operational needs of firefighters, as they typically require enough air to last through dynamic situations like firefighting or rescue missions, while still being manageable to transport. The 30-minute and 60-minute cylinders are not housed in this system because they serve different operational parameters; 30-minute cylinders contain less air, which may not be sufficient for prolonged scenarios, and 60-minute cylinders are usually bulkier and less favored for typical firefighting use due to their increased weight. The air refill cylinders mentioned are not appropriate for housing in a system meant for equipped usage, as they are intended for refilling and not for active service in the field.
