DescriptionDescriptionThe breathing air is circulated in a closed breathing cycle. Thecarbon dioxide contained in the exhaled air is absorbed in aregeneration cartridge (CO2 absorber).The breathing air is enriched with oxygen from the oxygencylinder— via the constant metering valve, in the case of low breathingrates, and— via the minimum valve or a manually operated bypass valvein the case of higher breathing rates.Before the regenerated breathing air is inhaled again, it flowsthrough the air cooler. When it is filled with ice thetemperature of the inhaled air is lowered, thus reducing thephysical strain on the user.The use of ice in the cooling system is only required at ambienttemperatures above 32 oF (0 oC). At temperatures below32 oF (0 oC), ice must never be used.A positive pressure in the breathing circuit prevents ambientair from entering the system.Only use the corresponding full-face masksPanorama Nova – EPDM – PC – RP orPanorama Nova – SI – PC – RPThey are connected to the PSS BG 4 via a quick and easyplug-in coupling.The electronic monitoring system comprises sensor unit,switch-box and Sentinel. It continuously measures thepressure in the oxygen cylinder, indicates this pressure on theSentinel, tests and monitors the correct functioning of thePSS BG 4 and generates a warning when the residualpressure is reached as well as in the event of malfunctions.Sentinel provides continuous monitoring of the PSS BG 4equipment and movement of the wearer.Sentinel incorporates the following features:— Monitoring of available oxygen pressure of the PSS BG 4equipment;— Remaining period of use in minutes until approx.700 psi/55 bar residual pressure warning is generated;— Movement Sensor and Automatic Distress Signal Unit(ADSU). This feature is active only when the ‘Tally’ isremoved;— Yellow panic button activated manual Distress Signal-Unit(DSU);— Battery capacity;— A ‘Back Light’ feature – illumination of the display;— Residual pressure warning at 700 psi/55 bar;— Ambient temperature;— Intrinsic safety approved;— Low pressure warning which warns during use that eitherthe cylinder valve is closed or the oxygen cylinder is empty.Available for Sentinel are ‘snap on’ IR-Link and Windowsbased Software Packages for the programming of additionalmonitoring options and datalogging with downloading ofdatalogged parameters.Details of variants, approved accessories and IR-Link withWindows based Software. Package Options are availablefrom Dräger Safety on request.The PSS BG 4 equipment with the permitted breathingapparatus connections complies with— the European standard DIN EN 145 and— the European PPE Directive 89/686/EEC.The Sentinel electronic monitoring system satisfies theexplosion-protection (intrinsic safety) tests in accordance withEN 50 020 regulation:—EEx ia IIC T4—EEx ia IThe Sentinel meets the explosion-proofing standards toEEx ia IIC T4 and EEx ia I and is approved for the use ingaseous mines by MSHA.6
Prerequisites for UsePrerequisites for Use— The possible need for protective clothing and headprotection must be noted when verifying the conditions foruse.— National regulations must be strictly followed, such as (forGermany):BGR 190 "Regulations for the use of breathing apparatus"BGI 504-26: Selection criteria for special industrial medicalprecautions in accordance with recommendation G 26"Breathing apparatus" published by the employers' liabilityinsurance association.Cautions and Limitations(Refer to the approved User Instruction manual for thecomplete list of sub-assembly component parts that make upthe approved assembly).J - Failure to properly use and maintain this product couldresult in injury or death.M- All approved respirators shall be selected, fitted, used, andmaintained in accordance with MSHA, OSHA, and otherapplicable regulations.N - Never substitute, modify, add, or omit parts. Use only exactreplacement parts in the configuration as specified by themanufacturer.O - Refer to User s Instructions, and/or maintenance manualsfor information on use and maintenance of theserespirators.S - Special or critical user s instructions and/or specific uselimitations apply. Refer to User s Instructions beforedonning.S – Special or Critical User s Instructions— Approved for use at temperatures above 23 oF (–5 oC).— The use of ice in the cooling system is only required atambient temperatures above 32 oF (0 oC).At temperatures below 32 oF (0 oC) ice must never beused.— The cylinder is to be charged with compressed oxygenmeeting U.S.P. specifications.— Anti-fog solution R 52 560 or R 52 550 must be appliedbefore each use.— The CO2 absorber must never be used after its indicatedexpiration date. See Instructions for Use of refill cartridge90 21 360.— Never re-use factory-packed cartridge R 34 360.— After each use of the PSS BG 4, a fully charged cylinderand a recharged CO2 absorber must be installed.— Thorough cleaning and disinfecting of facepiece, breathingtube and breathing bag must be done in accordance withthe manufacturer s instructions.— When used as a Pressure Demand Apparatus, thefollowing Warnings and Limitations apply:— Do not use this apparatus where there is directexposure of open flames or in high radiant heat.— Keep exposed hair to a minimum when using theapparatus near open flames or in high radiant heat.— A good facepiece seal is crucial since facepieceleakage will seriously reduce service time.— Use of pure oxygen or oxygen enriched air increasesflammability and lowers the ignition temperature of mostmaterials.7
