Study Notes

Air and Oxygen Fill Systems

The air fill station at Station 22 is located in the hose room and must be inspected by the Company Officer of Engine 22 and/or Tower 22 by 0900 hours every morning.
The 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.
Only authorized personnel who are trained to operate the breathing air compressor can turn it on.
The compressor must be operated according to the manufacturer's specific operations.

Cascade System (Reserve Tower 22)

The cascade system on Reserve Tower 22 must be inspected during apparatus inspection every morning.
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 conditions are not present, it must be reported to the Company Officer of Engine 22 and/or Tower 22, and arrangements will be made to have the cascade filled.
The cascade on Reserve Tower 22 is to be filled to 6,000 psi using Station 22's fill station and the station air compressor.

Oxygen Cascade System

The oxygen fill station bottle status at Station 22 must be inspected every morning by 0900 hours.
If the system does not have at least 6 cylinders with greater than 300 psi, the EMS Officer must be contacted.

Refilling Guidelines

No oxygen, SCBA, or SCUBA cylinders are to be refilled higher than their rated capacity.
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.
The regulator must be adjusted to the appropriate pressure setting prior to flowing any air into the cylinder or tank.
Tanks or cylinders must be placed in their appropriate protective shield when being refilled.
All small oxygen tanks must be refilled utilizing the fragmentation shield when using the Station 22 oxygen cascade system.
All SCBA and SCUBA cylinders must be refilled utilizing the fragmentation shield when using the Station 22 fill station or the Reserve Tower 22 cascade system.
Approved eye protection must be worn during the refilling of all small oxygen tanks, SCBA, and SCUBA tanks.
