Safety Message • Wear the proper PPE. Eye protection should always be worn because there is a risk that particles or debris can be blown into the eye. Hearing protection is also used if there is a consistent hissing or whistling of air leaks. Do not engage in any type of horseplay with high-pressure air. • Faulty hoses, air lines and junction points are immediate out of service items. Contact the BA shop for repair. • Shut down all surrounding equipment in the work area and listen for the ‘hissing’ of the air. This will identify where the air leak is so the leak can be repaired. BALTIMORE COUNTY FIRE SAFETY & LOGISITICS 6

Continued • Frequently audit the condition of the compressor, pressure gauges and oil regulators. Erroneous readings on gauges and substandard condition of the pump can create a significant safety hazard. • Always de-energize the equipment before working on any high-pressure air systems. Make sure all pressure has dissipated before starting any work. BALTIMORE COUNTY FIRE SAFETY & LOGISITICS 7

Operational Guidelines • Conduct a visual inspection of the unit before starting, each time. • Do not tamper with, modify, or bypass safety devices. • Do not tighten or adjust fitting or connections under pressure. BALTIMORE COUNTY FIRE SAFETY & LOGISITICS 8

Operation Guidelines Continued • Ensure all internal pressures are vented before opening separator, purification chamber and compressor block. • Before working on any electrical system, disconnect the electrical supply at the circuit break or main disconnect. • Do not use gasoline, diesel fuel or other flammable products as a cleaning solution in breathing air compressor.

Compressor Controls BALTIMORE COUNTY FIRE SAFETY & LOGISITICS 43

Space Saver Fill Panel With Auto Cascade • There is 1 control valve for Each cabinet on the left and right. • The panels are equipped with an auto cascade feature. There are no control valves for the banks. • When filling it will automatically switch to the next bank when filling. • There is 1 auxiliary refill port. BALTIMORE COUNTY FIRE SAFETY & LOGISITICS 44

Space Saver Fill Containment Station • 1 regulator controls the pressure feeding both fill stations once set. • The fill station is also protected by a relief valve. • Each fill station position has its own ON/OFF valve allowing for control of your filling for each bottle. • The door must be completely down and locked for air to flow into your cylinders. BALTIMORE COUNTY FIRE SAFETY & LOGISITICS 45

Inside The Space Saver • You must turn the Dring to unlock and lift to open the Space Saver door. • The cylinder holder will lower and tilt outward to allow you to remove and replace the SCBA bottles easily. • There is a 347 adapter, ON/OFF valve and bleed valve on each fill line. BALTIMORE COUNTY FIRE SAFETY & LOGISITICS 46

Inside The Space Saver • Once connecting the bottle/s you will tilt the holder towards the back of the cabinet to allow for the door to close. • To lower the door you will push down on the top and use the D-ring to lock it closed. • Once the door is closed and locked it will allow air to flow into the bottles for filling. BALTIMORE COUNTY FIRE SAFETY & LOGISITICS 47

Carbon Monoxide Sensor Cell The Carbon Monoxide Sensor Cell is an electro-chemical element inside the CO Monitor which senses the amount of Carbon Monoxide in the air stream and produces an analog electrical signal for the control and display functions of the CO Monitor. 1 2 BASIC CALIBRATION KIT 3 1. 20 PPM CO TEST GAS (CLY-0016) 2.

Bauer GAS-TEK Monitors • The gas monitors are a factory installed option which was ordered with the unit. • The oxygen (O), carbon monoxide (CO), and carbon dioxide (CO 2) monitors sample the gas as it leaves the unit. • The hydrogen sulfide (H 2 S) monitor samples the ambient air. The O, CO, and H 2 S monitors use an electrochemical sensor element to detect the targeted gas. • The CO 2 monitor uses an infrared sensor to detect the CO 2 BALTIMORE COUNTY FIRE SAFETY & LOGISITICS 50

Bauer GAS-TEK Operation • The Bauer Gas-Te. K monitors work automatically when enabled on the “Gas Sensors” portion of the program. • The regulator reduces the pressurized air/gas to levels the monitors can use. When any of the sensors detect the set concentration of gas it activates an alarm condition and shuts down the compressor unit. • Once the gas concentration has returned below the acceptable limit, the monitor will allow the unit to be restarted. BALTIMORE COUNTY FIRE SAFETY & LOGISITICS 51

Documentation • Must be filled out every time a cylinder is filled per NFPA mandatory requirement • Log will be maintained on the unit in a dry location • Station Officers shall monitor adherence to policy 52

Conclusion • If you have additional questions about the unit, equipment or operations. Please consult with Fire Maintenance 2 for additional guidance. BALTIMORE COUNTY FIRE SAFETY & LOGISITICS 53
