HOFFMAN ESTATES FIRE DEPARTMENT STANDARD OPERATING GUIDELINES SOG Category & Identification Number: EFFECTIVE DATE: Equipment Guidelines – 002 January 1, 2022 NIMS COMPLIANT SOG Title: Air and Oxygen Fill Systems Revision: 4 APPROVED BY: NUMBER OF PAGES: Re-evaluation Date: Alan Wax January 1, 2026 Fire Chief 2 PURPOSE POLICY A. Air Fill Station Each morning, Station 22's air fill station (located in the hose room) pressure will be inspected by the Company Officer of Engine 22 and/or Tower 22 by 0900 hours. Tank gauges on the fill station should indicate 4,500 psi or greater and at least one of the tank gauges should indicate at least 5,500 psi. The compressor will be turned on only by those personnel appropriately trained and authorized to operate the breathing compressor. The compressor must be operated according to the manufacturer's specific operations. B. Cascade System (Reserve Tower 22) Each morning during apparatus inspection, the cascade system on Reserve Tower 22 will be inspected by the apparatus operators. All tank gauges should indicate 4,500 psi or greater and at least one of the tank gauges should indicate 5,500 psi or greater. If both of these conditions are NOT present, it should be reported to the Company Officer of Engine 22 and/or Tower 22. Arrangements will be made to have the cascade filled and the compressor turned on according to the guidelines stated above. The cascade on Reserve Tower 22 is to be filled to 6,000 psi using Station 22's fill station (located on the apparatus floor) and the station air compressor. C. Oxygen Cascade System Each morning, Station 22's oxygen fill station bottle status will be inspected by the Company Officer of Engine 22 by 0900 hours. If the system does not have at least 6 cylinders that have greater than 300 psi, the EMS Officer is to be contacted. 1 PROCEDURE Refilling Guidelines No oxygen, SCBA, or SCUBA cylinders are to be refilled higher than their rated capacity. In addition, all tank and cylinder hydrostatic stamps must be checked and must be within approved limits (5 years for all steel, aluminum and carbon composite and 3 years for all fiberglass wrapped cylinders and carbon composite cylinders manufactured in 2000 or older) in order to be filled In addition, follow the appropriate guidelines. A. Adjust the regulator to the appropriate pressure setting prior to flowing any air into the cylinder or tank. The regulators will need to be adjusted whenever cylinders or tanks are being refilled using the Station 22 fill station or the Reserve Tower 22 cascade system. B. Place the tanks or cylinders in their appropriate protective shield. 1. All small oxygen tanks must be refilled utilizing the fragmentation shield when using the Station 22 oxygen cascade system. (Note: Approved eye protection is to be worn during the refilling of all small oxygen tanks.) 2. All SCBA and SCUBA cylinders must be refilled utilizing the fragmentation shield when using the Station 22 fill station. (Note: Approved eye protection is to be worn during the refilling of all SCBA or SCUBA tanks.) 3. All SCUBA and SCBA cylinders must be refilled using the Reserve Tower 22 fragmentation shield when refilling using the Reserve Tower 22 cascade system. (Note: Approved eye protection is to be worn during the refilling of all SCBA or SCUBA tanks.) 4. The cascade systems on Reserve Tower 22 is to be refilled only using 6,000 psi rated fill hoses (found in apparatus). (Note: Approved eye protection is to be worn during the refilling the tanks on Reserve Tower 22.) DEFINITIONS EXCEPTIONS REFERENCES End of Document 2
