Each cylinder will be clearly marked with a label stating the cylinders working pressure type of gas and time of visual inspection.

Each cylinder will have a CGA 702 valve and (NFPA 1901) compliant valve protection device. Each cylinder shall be plumbed directly to the containment style fill station using 7000 Psi hose and stainless-steel fittings. Each cylinder will be new and have a current test date.

4.4. Filling Station

Two Position Containment Style Fill Station Model CFS5.5-2Sx4x4 (or equivalent)

The fill station shall be built and tested to conform to (NFPA 1901)

The fill station shall be mounted so as to direct expanding air away from the operator in the unlikely event of a cylinder failure.

The fill station shall be built and tested to conform to NFPA 1901, 2016 Edition.

The fill station shall be designed for mobile applications. The fill station shall be constructed of formed plate steel and shall be fully enclosed.

The fill station shall be warranted free from defects in material and workmanship for a period of eighteen months from date of shipment or twelve months from date of start-up, whichever expires first.

Containment Fill Station

The front-loading, two position; containment fill station shall totally enclose the SCBA or SCUBA (SCUBA cylinders not to exceed 31” length) cylinders during the refilling process.

The fill station’s outer enclosure and door assemblies shall be constructed of formed ¼ inch thick plate steel. Venting shall be provided in the bottom of the fill station to allow the rapidly expanding air from a ruptured cylinder to escape from the fill station. The fill station shall be ergonomically designed for maximum operator convenience and safety for refilling cylinders. The fill station door and cylinder holder assembly shall tilt out towards the operator 45 degrees, providing unobstructed access to the cylinder holder to load and unload the cylinders. A handle and heavy-duty gas spring shall be incorporated into the design of the fill station to assist the operator in opening and closing the fill station door. It shall take no more than approximately eighteen pounds of effort to open or close the fill station door thereby eliminating operator fatigue.

Each cylinder holder shall be lined to prevent scuffing the outer surface of the SCBA cylinders. For complete operator protection, the fill station shall include a safety interlock system that will prevent refilling SCBA cylinders unless the fill station door is closed and secured in the locked position. The automatic interlock will require no actuation of secondary latching mechanism on the outside of the fill station.

Two fill hoses shall be located within the fill station. Each fill hose shall be equipped with a bleed valve and

SCBA fill adapter of choice. Fill hose retainers shall be provided to anchor the fill hoses when not in use.

Control Panel

The fill control panel shall be installed at the front of the fill station. The control panel shall be factory piped and designed to fill two SCBA or SCUBA cylinders either independently or simultaneously.

The control panel shall include the following standard features:

• Inlet pressure gauge

• Adjustable pressure regulator

• Regulated pressure gauge

• Two (2) fill control valves

• Two (2) fill pressure gauges

• One (1) relief valve for regulated fill pressure

• Four (4) Cascade control valves

• Four (4) Cascade Control Gauges

• One (1) auxiliary refill port with 6000 psi quick connect adapter and valve.

All piping and tubing should be properly supported and protected to prevent damage from vibration during shipment, operation, or maintenance. Piping and tubing shall be installed in a neat and orderly arrangement, adapting to the contours of the station. All instrument tubing shall be 300 series stainless steel.

All control panel mounted pressure gauges shall be 2 ½” diameter and be liquid filled. All panel-mounted components shall be labeled with a nameplate.

The fill station shall be provided on its own freestanding base and shall not exceed the following approximate dimensions: 58” high, 30” wide, and 22” deep. Weight with base and control panel shall not exceed 750 lbs.

4.5. Electronic Digital Readout (CO) Carbon Monoxide Monitor Model BAS-4021 (or equivalent)

The monitor shall be powered by 12-volt DC and be mounted in the trailer with the compressor and shall only be on when the compressor is operating.

A. The monitor shall be designed to monitor breathing air for Carbon Monoxide. It shall have a range of

0-50 ppm and be rated for 6000-psi inlet pressure.

B. The unit shall be powered by 12 volts DC.

C. The unit shall incorporate an electric-chemical sensor that puts out a signal that is displayed on an

LCD display.

D. The electronics shall be enclosed in a NEMA-4 dust and drip tight enclosure.

E. An audible alarm shall be standard. It shall have a sound level of 95 decibels.

F. The unit shall be equipped with an alarm level, preset but field adjustable. There shall be a red light to indicate alarm. The alarm level will have terminals that will be connected to shut down the compressor.

G. The supplied calibration gas will have a flexible connection that will allow the user to choose to calibrate the monitor.

H. A shut off valve shall be supplied so that the monitor can be removed from the system without interrupting service in the event of needed repairs or failure.

I. A complete bound operator’s manual shall be provided.

4.6. Supplier Requirements
