The inherent hazards associated with re ghting and all-hazards mitigation requires the use of Self-contained Breathing Apparatus (SCBA). The human respiratory system is a sensitive and delicate group of organs The lungs and respiratory tract are probably more vulnerable to injury than any other part of the body. Standard Operating Procedures at all incidents include not entering any structure or atmosphere that is charged with smoke or re gases, or any other suspected respiratory hazard, unless one is equipped with an SCBA. The most appropriate approach to take at all incidents is to assume that any smoke and gases that are present are hazardous to all humans, including victims, bystanders and re ghters. An atmosphere should be considered hazardous when any one of the following is present: High heat Smoke Toxic gases Oxygen de ciency Suspected hazardous material release Moreover, modern buildings are constructed with materials, which release toxic chemicals as they burn. Failure to use an SCBA in hazardous atmospheres greatly increases the chance that re ghters will be unnecessarily exposed to inhaled poisons and deadly levels of carbon monoxide and other toxic gases. Additionally, proper use of an SCBA will protect the user from inhaling dangerously high levels of heat associated with re ghting, which have the potential to damage the lungs and respiratory tract. If there is any doubt whether an SCBA is required, re ghters should always err on the side of safety. All St. John’s Fire District re ghters shall receive training and be pro cient in the proper use of the MSA G1 SCBA. Fire ghters must be able to demonstrate pro ciency in all aspects of SCBA use, including donning and dof ng, performing a face piece Fit Check, Pak-Alert sensor module operation, emergency operations, maintenance and testing procedures and proper cleaning procedures. Additionally, re ghters should be able to demonstrate a thorough knowledge of the unit’s speci cations. 3 fi fi fi fi fi fi fi fi fi fi fi fi fi fi fi fi fi fi fi fi fi fi fi Reference Procedures Respiratory Protection Air Management Standard Operating Guideline 203.09 Safe Structural Firefighting MSA G1 The MSA G1 - referred to hereafter as SCBA - is a pressure-demand self-contained breathing apparatus (SCBA) operating independent of the ambient air for use in atmospheres immediately dangerous to life or health. Breathable air is supplied to the user from a compressed air cylinder via a pressure reducer, a regulator and a facepiece. The exhalation air is released directly into the ambient atmosphere. Safety Regulations The MSA G1 SCBA complies with the National Institute for Occupational Safety and Healthy (NIOSH) regulation under 42 CFR Part 84 for open circuit self- contained breathing apparatus, the National Fire Protection Association (NFPA) Standard 1981 on Open-Circuit Self-Contained Breathing Apparatus (SCBA) for Emergency Services and the NFPA Standard 1982 on Personal Alert Safety Systems (PASS). Components The MSA G1 - referred to hereafter as SCBA - is a pressure-demand self-contained breathing apparatus (SCBA) operating independent of the ambient air for use in atmospheres immediately dangerous to life or health. Breathable air is supplied to the user from a compressed air cylinder via a pressure reducer, a regulator and a facepiece. The exhalation air is released directly into the ambient atmosphere. Facepiece The facepiece provides breathable air from the regulator past an inhalation valve to the inside of the lens (to minimize lens fogging) and then through the check valves into the nosecup. Exhaled air is directed out of the exhalation valve by the nosecup directly to ambient air. The face seal provides a snug, comfortable fit, and tight seal. The facepiece is equipped with a mechanical speech diaphragm that enhances speech communication. The HUD is provided inside the facepiece through light pipes from the regulator. 4 When in safe atmospheres with no regulator attached, ambient air can be inhaled directly through an opening to facilitate breathing and speaking with minimal resistance. The facepiece provides NFPA compliant heat protection of 500° up to 5 minutes. The SCBA Facepiece is individually assigned and issued as a piece of Personal Protective Equipment. Regulator (also referred to as Demand Valve) The mask-mounted G1 Regulator is a pressure-demand regulator, which maintains a positive pressure in the facepiece while the SCBA is in use. The positive pressure regulator reduces the pressure coming from the pressure reducer further to provide breathable air to the user. The regulator is connected to the facepiece with a fixed position Push-To-Connect (PTC) connection. The Regulator serves as the second stage and is activated by first sharp inhale and capable of providing a minimum of 350 LPM. The regulator includes a bypass valve with a large and easily accessible bypass (red) knob and an electronic module that provides functionality for Heads-Up Display (HUD) and electronic voice communications. The bypass valve offers variable flow up to 120 liters when fully opened with four turns. The microphones are activated when the regulator is connected to the facepiece and the user begins breathing. Inhalation noise is not amplified by the system. The District’s SCBA utilizes a continuous hose to provide an uninterrupted connection from the pressure reducer to the regulator. G1 Heads-Up Display (HUD) The HUD is integrated into the regulator and projects light into the facepiece. The HUD allows users to see the cylinder pressure and alarm status while wearing the SCBA. The HUD receives the information on the SCBA and power from the power module. The HUD consists of 7 LEDs which are separated on the left and right sides to improve visibility and clarity. 5 G1 Pressure Reducer The pressure reducer reduces the cylinder pressure to an intermediate pressure of 115 PSI, which is in turn further reduced by the regulator to a pressure that is respirable by the user. The pressure reducer incorporates a fail safe design which ensures air flow to the user in the event of a malfunction within the pressure reducer. The relief valve activates at 200-250 PSI. The pressure reducer connects to the cylinder valve assembly with a handwheel assembly. The pressure reducer incorporates an intermediate pressure relief valve, and a cylinder connector with a sintered filter to capture particulates. The pressure reducer connects to the cylinder by a Quick Connect fitting. To disconnect, twist 1/4 turn and pull away from the cylinder valve assembly male quick-connect adapter. Push directly in to lock into place. A Safety Pin activates when the cylinder is turned on to prevent accidental disconnection. G1 Power Module The power module serves as the power supply and provides all of the information for the control module, regulator and speaker module. The power module is connected to the backplate. It connects to the rechargeable battery module, emits audible PASS alarms and pre-alarms and has 4 buddy lights. The rechargeable battery module contains non replaceable lithium-ion cells. The system notifies the user when the batteries need to be recharged by emitting an audible tone from the power module, displaying an empty battery icon on the display of the control module, and by a flashing yellow LED on the HUD. The power module is also equipped with a RIT light, which activates when low pressure alarm occurs, to make it easier to see the UAC in the dark. The power module has a data logging feature that records information about the SCBA while the control module is turned on. The power module contains an internal real time clock. G1 Control Module The G1 control module is the user’s interface with the SCBA and PASS device. The control module is assembled to the high pressure air source and to the power module by a pneumatics and electronic hose assembly. It is equipped with an analog gauge as well as a graphical display to provide vital information: Time Remain (Estimated) numeric cylinder 6 pressure, battery status, and alarms. When the control module is being read by the user, no buddy lights on the control module will flash and a white gauge light will illuminate, to enable the user to read the gauge and display. The integrated PASS motion sensor is housed within the control module. The ALARM button of the control module activates the full PASS alarm with or without air pressure. PASS Device The PASS device on the G1 SCBA is made up of three components: Battery Module Power Module Control Module The PASS device provides the user the ability to monitor movement through a motion sensor. The PASS device will go into pre-alarm with 20 seconds of being motionless. When a user remains motionless for 30 seconds, the PASS device goes into full alarm to alert those around the user. The PASS device also monitors cylinder pressure and battery status. G1 Speaker Module The speaker module amplifies and clarifies the speech from the facepiece during use. When inhaling, the breathing sound will not be amplified. The speaker module is turned OFF when the complete SCBA is turned OFF and can also be activated/ deactivated with its button. Pressing of the button is acknowledged by a beep. Battery The MSA G1 power supply is powered by a rechargeable Lithium Ion battery. All lights, communication, and controls are powered by this source. The battery provides 6-8 hrs of continuous use with all features active. Battery status can be checked without powering on SCBA. Press and hold both or one green button for 3-5 seconds. Change the battery when the battery power is yellow, indicating two hours remain. Batteries take between 4-6 hours to fully charge. The removal tool is located on the shoulder. 7 Cylinder Valve Assembly The cylinder valve assembly includes a large pressure gauge with a photoluminescent face. The handwheel for the cylinder valve assembly non- locking handwheel. The cylinder valve assembly includes a pressure-relief device to vent pressure safely if the cylinder is over pressurized. Primary Low Pressure Warning Device (Bell) The pressure reducer includes a bell alarm for low pressure that actuates at 35 percent of the SCBA’s rated service pressure during use. This will activated at approximately 1575 PSI and 16 minutes of remaining service. G1 Carrier and Harness Assembly The harness and carrier assembly consists of: Backplate (houses the power module, battery module, and pressure reducer) Cylinder band with latch to hold the cylinder Shoulder pads Adjustable pull straps Lumbar pad Waist belt Regulator Keeper Backplate The carrier and harness assembly includes an ergonomic backplate. The backplate includes large handles to facilitate handling and storage. The hop handle of the back plate has a drag rating of 1000 lbs. The side handles are rated to 500 lbs. Cylinder Band The metal cylinder band and latch securely retain the cylinder and provide a rigid opening to enhance cylinder installation and removal. Shoulder Pads The shoulder pads provide weight distribution across the shoulder, friction pad to prevent slippage of the straps, increased visibility with retroreflective material, and steel buckles for a secure fit. The tunnels on these pads are released using snap buttons to ease in swapping or repair of components. The inside and outside of the shoulder straps are identifiable by print/stitching. A facepiece clip can also be attached to either shoulder strap. Lumbar Pad 8 The adjustable lumbar pad provides the user three positions for ideal comfort. The lumbar pad can be adjusted by one-hand and can be adjusted while worn. The lumbar pad also has a swivel feature to allow it to move with the user. Cylinder The District’s utilizes the low-profile Eclipse cylinder. The cylinder is visually distinguishable by its black color. Constructed of a seamless aluminum liner that is fully wound over entire surface (except for thick neck area) with high-strength carbon fiber filament impregnated with epoxy resin and a final over-wrap of fiberglass fibers. The District’s cylinder is 4500 PSI with a rated service time of 45 minutes. The cylinder has a weight of 13.5 lbs. and a diameter of 6.1 inches. The minimum pressure for the SCBA to be in service is 4050 PSI. Do NOT use cylinders that are not filled to the maximum working pressure. Do NOT put cylinders that are partially charged in storage. Rapid Intervention Team/Universal Air Connection (RIT/UAC) The pressure reducer is equipped with a Rapid Intervention Team/Universal Air Connection (RIT/UAC) fitting. The RIT/UAC fitting is for use by rapid intervention teams for emergency filling operations. The SCBA includes an automatically resetting pressure relief valve to vent excess pressure if the SCBA is over pressurized during an emergency filling operation. NOTE: The UAC is compatible with all SCBA manufacturers. 9 Donning Don SCBA by placing arms through the shoulders straps. Connect waist belt. Pull forward on the waist strap pull tabs to tighten the belt for a snug fit. Pull down on the shoulder pull straps to tighten the straps. Adjust as necessary. 10 Start-up Sequence When the PASS device goes out of sleep mode, it goes into a start-up sequence that provides information to the control module about the state of the SCBA for operation. The logo screen shows the MSA logo and a Unit and the Riding Position if assigned to the device, on the control module. The buddy lights on the power and control modules cycle through red, yellow, and green. The power module plays the start-up tone. During this process, the PASS device does a self-test to make sure the device is operating correctly. The self-test screen shows the results of the self-test. A successful self-test shows a Go icon to indicate the SCBA can be put into service. If maintenance is necessary, the overhaul reminder icon shows to indicate the SCBA should be removed from service after use. If the SCBA should not be used, a Hardware Alarm icon shows on the control module and a full alarm from the power module is activated. The PASS device will not continue to operate. Remove the SCBA from service. The primary screen shows and the SCBA can be used. Primary Screen The primary screen provides all critical information to the user. The District’s SCBA are configured with the primary screen to display a calculated remaining service time. The countdown timer displays the estimated rated service pressure until 35% remaining, corresponding with the Air Management Guideline. The actual time remaining may be less than the calculated time displayed. Increases in breathing rate may reduce remaining time more than expected. Use the time indicator as a general guide only. The time displayed is based on the continuation of the average breathing rate over the last three minutes. Increases in the breathing rate after checking the displayed time may result in less remaining time than anticipated. Secondary Screen The secondary screen can be accessed by pressing the green button once. The secondary screen displays the following information: 11  Temperature Gauge Bluetooth Connectivity Long Range Radio Icon Battery Status Pressure PRESSURE COLOR DISPLAY 50 - 100% Green 36 - 49 % Yellow 0 - 35% Red HUD Pressure Status The HUD provides the pressure and alarm status through light pipes into the facepiece. The pressure status shows on the user's right side. The alarm status shows on the user's left side. The pressure status indicators are divided into the following four segments, which are based on the percentage of the maximum pressure of the cylinder. Each segment is associated with a specific number and color of LEDs. SEGMENT PRESSURE RANGE HUD LED Segment 1 75 - 100% Segment 2 50 - 74% Segment 3 36 - 49 % Segment 4 0 - 35% 12 SCBA Unit Identifier The SCBA will be outfitted with a unit identifier that corresponds with the apparatus.
