This would include,but is not limited to, correct use of Personal Protective Equipment (PPE), correct useof storage vials, and correct handling of chemicals, as defined in the laboratory’sinternal safety analysis and standard operating procedures. Failure to adhere tolaboratory safety practices could lead to injury or death.Many internal parts of the GC carry dangerous voltagesIf the GC is connected to a power source, even if the power switch is off,potentially dangerous voltages exist on:•The wiring between the GC power cord and the AC power supply, the AC power supply itself, and the wiring from the AC power supply tothe power switch.With the power switch on, potentially dangerous voltages also exist on:•All electronics boards in the instrument.•The internal wires and cables connected to these boards.•The wires for any heater (oven, detector, inlet, or valve box).All these parts are shielded by covers. With the covers in place, it should be difficultto accidentally make contact with dangerous voltages. Unless specificallyinstructed to, never remove a cover unless the detector, inlet, or oven are turned off.If the power cord insulation is frayed or worn, the cord must be replaced. Contactyour Agilent service representative.IntroductionDo not use an Uninterruptable Power Supply (UPS) with a GCIf the area where the GC is located suddenly looses power, an unsafecondition can result if the GC remains powered on. Do not use the GCwith a UPS.Electrostatic discharge is a threat to GC electronicsThe printed circuit (PC) boards in the GC can be damaged by electrostaticdischarge. Do not touch any of the boards unless it is absolutelynecessary. If you must handle them, wear a grounded wrist strap and takeother antistatic precautions. Wear a grounded wrist strap any time youmust remove the GC right side cover.Many parts are dangerously hotMany parts of the GC operate at temperatures high enough to causeserious burns. These parts include but are not limited to:•The inlets•The oven and its contents•The detectors•The column nuts attaching the column to an inlet or detector•The valve boxYou should always cool these areas of the GC to room temperature beforeworking on them. They will cool faster if you first set the temperature ofthe heated zone to room temperature. Turn the zone off after it hasreached the setpoint. If you must perform maintenance on hot parts, use awrench and wear thermally protective gloves. Whenever possible, cool thepart of the instrument that you will be maintaining before you beginworking on it.Be careful when working behind the instrument. During cool-down cycles, the GCemits hot exhaust which can cause burns.IntroductionThe insulation around the inlets, detectors, valve box, and the insulation cups ismade of refractory ceramic fibers. To avoid inhaling fiber particles, we recommendthe following safety procedures: ventilate your work area; wear long sleeves,gloves, safety glasses, and a disposable dust/mist respirator; dispose of insulationin a sealed plastic bag; wash your hands with mild soap and cold water afterhandling the insulation.Oven thermal leaksObjects passing through the oven door seal can cause thermal leaks which createhazardous hot spots which cause burns and melt equipment.Do not allow wiring or temperature probes to pass through the oven doorjam. Agilent recommends using one of the access holes.Introduction Hydrogen SafetyHydrogen gas may be used as carrier gas, and/or as fuel for the FID, FPD,and NPD. When mixed with air, hydrogen can form explosive mixtures.When using hydrogen (H2) as the carrier gas or fuel gas, be aware that hydrogengas can flow into the GC oven and create an explosion hazard. Therefore, be surethat the supply is turned off until all connections are made and ensure that the inletand detector column fittings are either connected to a column or capped at all timeswhen hydrogen gas is supplied to the instrument.Hydrogen is flammable. Leaks, when confined in an enclosed space, may create afire or explosion hazard. In any application using hydrogen, leak test allconnections, lines, and valves before operating the instrument. Always turn off thehydrogen supply at its source before working on the instrument.Hydrogen is a commonly used GC carrier gas. Hydrogen is potentiallyexplosive and has other dangerous characteristics.•Hydrogen is combustible over a wide range of concentrations. Atatmospheric pressure, hydrogen is combustible at concentrations from4% to 74.2% by volume.•Hydrogen has the highest burning velocity of any gas.•Hydrogen has a very low ignition energy.•Hydrogen that is allowed to expand rapidly from high pressure into the atmosphere can self-ignite due to an electrostatic spark.•Hydrogen burns with a nonluminous flame which can be invisible under bright light.GC precautionsWhen using hydrogen as a carrier gas, remove the large round plasticcover for the MSD transfer line located on the GC left side panel. In theunlikely event of an explosion, this cover may dislodge.IntroductionHydrogen shutdownHydrogen gas may be used as a carrier or as fuel for some detectors.When mixed with air, hydrogen can form explosive mixtures.The GC monitors inlet and auxiliary gas streams. If a stream shuts downbecause it is unable to reach its flow or pressure setpoint and if thatstream is configured to use hydrogen, the GC assumes that a leak hasoccurred and declares a hydrogen safety shutdown. The effects are:•The offending channel and any associated channels (such as septumpurge) are set off.•The split valves in the split/splitless and PTV inlets open.•The oven (heater and fan) turns off.•The small heated zones are turned off.•An alarm tone sounds.To recover from this state, fix the cause of the shutdown (tank valveclosed, serious leak, others). Turn the instrument off, then back on.The GC cannot always detect leaks in inlet and/or detector gas streams. For thisreason, it is vital that column fittings should always be either connected to acolumn, or have a cap or plug installed. The H2 streams must be configured forhydrogen so that the GC is aware of hydrogen use.IntroductionDangers unique to GC/MSD operationHydrogen presents a number of dangers. Some are general, others areunique to GC or GC/MSD operation. Dangers include, but are not limitedto:•Combustion of leaking hydrogen.•Combustion due to rapid expansion of hydrogen from a high-pressure cylinder.•Accumulation of hydrogen in the GC oven and subsequent combustion (see your GC documentation and the label on the top edge of the GCoven door).•Accumulation of hydrogen in the MSD and subsequent combustion. Hydrogen accumulation in a GC/MSDThe GC/MSD cannot always detect leaks in inlet and/or detector gas streams. Forthis reason, it is vital that column fittings should always be either connected to acolumn, or have a cap or plug installed. The H2 streams must be configured forhydrogen so that the GC is aware of hydrogen use.All users should be aware of the mechanisms by which hydrogen canaccumulate (Table 1) and know what precautions to take if they know orsuspect that hydrogen has accumulated. Note that these mechanisms applyto all mass spectrometers, including the GC/MSD.Table 1Potential hydrogen accumulation mechanisms in GC/MSDMechanism ResultsMass spectrometer turned off A mass spectrometer can be shut downdeliberately. It can also be shut down accidentallyby an internal or external failure. A massspectrometer shutdown does not shut off the flowof carrier gas. As a result, hydrogen may slowlyaccumulate in the mass spectrometer.IntroductionMass spectrometer automated isolation valves closed Some mass spectrometers are equipped with automated diffusion pump isolation valves. In these instruments, deliberate operator action or various failures can cause the isolation valves to close. Isolation valve closure does not shut off the flow of carrier gas. As a result, hydrogen may slowly accumulate in the mass spectrometer.Mass spectrometer manual isolation valves closed Some mass spectrometers are equipped with manual diffusion pump isolation valves. In these instruments, the operator can close the isolation valves. Closing the isolation valves does not shut off the flow of carrier gas. As a result, hydrogen may slowly accumulate in the mass spectrometer.GC off A GC can be shut down deliberately. It can also be shut down accidentally by an internal or external failure. Different GCs react in different ways. If a 7890A GC equipped with Electronic Pressure Control (EPC) is shut off, the EPC stops the flow of carrier gas. If the carrier flow is not under EPC control, the flow increases to its maximum. This flow may be more than some mass spectrometers can pump away, resulting in the accumulation of hydrogen in the mass spectrometer. If the mass spectrometer is shut off at the same time, the accumulation can be fairly rapid.Power failure If the power fails, both the GC and mass spectrometer shut down. The carrier gas, however, is not necessarily shut down. As described previously, in some GCs a power failure may cause the carrier gas flow to be set to maximum. As a result, hydrogen may accumulate in the mass spectrometer.Table 1Potential hydrogen accumulation mechanisms in GC/MSD (continued)Mechanism ResultsPrecautionsTake the following precautions when operating a GC/MSD system with hydrogen carrier gas.Equipment precautionYou MUST make sure the front side-plate thumbscrew is fastenedfinger-tight. Do not overtighten the thumbscrew; it can cause air leaks.Major GC leaks or a column is missing or brokenIf the GC is off and configured for hydrogen, therear oven flap is open to vent out the hydrogen.Proper lab venting, as described in the Site Prepmanual, is recommended. If there is a significantleak, such as a missing column, the GC inlet, PCM,and Aux are provided with flow limiting frits tominimize any hydrogen accumulation within theoven. When the GC is on, major leaks are detectedautomatically.Table 1Potential hydrogen accumulation mechanisms in GC/MSD (continued)Mechanism ResultsOnce hydrogen has accumulated in a system, extreme caution must be used when removing it. Incorrect startup of a system filled with hydrogen can cause an explosion.After a power failure, the mass spectrometer may start up and begin the pumpdown process by itself. This does not guarantee that all hydrogen has been removed from the system or that the explosion hazard has been removed.Failure to secure your MSD as described above greatly increases the chance of personal injury in the event of an explosion.You must remove the plastic cover over the glass window on the front of a 5975 MSD. In the unlikely event of an explosion, this cover may dislodge.General laboratory precautions•Avoid leaks in the carrier gas lines. Use leak-checking equipment to periodically check for hydrogen leaks.•Eliminate from your laboratory as many ignition sources as possible (open flames, devices that can spark, sources of static electricity, etc.).•Do not allow hydrogen from a high pressure cylinder to vent directly to atmosphere (danger of self-ignition).•Use a hydrogen generator instead of bottled hydrogen.•Provide proper system ventilation as described in the Site Prep manual. Operating precautions•Turn off the hydrogen at its source every time you shut down the GC or MSD.•Turn off the hydrogen at its source every time you vent the MSD (do not heat the capillary column without carrier gas flow).•Turn off the hydrogen at its source every time isolation valves in an MSD are closed (do not heat the capillary column without carrier gas flow).•Turn off the hydrogen at its source if a power failure occurs.•If a power failure occurs while the GC/MSD system is unattended, even if the system has restarted by itself:1Immediately turn off the hydrogen at its source.2Turn off the GC.3Turn off the MSD and allow it to cool for 1 hour.4Eliminate all potential sources of ignition in the room.5Open the vacuum manifold of the MSD to atmosphere.6Wait at least 10 minutes to allow any hydrogen to dissipate.7Start up the GC and MSD as normal.When using hydrogen gas, check the system for leaks to prevent possiblefire and explosion hazards based on local Environmental Health andSafety (EHS) requirements. Always check for leaks after changing a tankor servicing the gas lines. Always make sure the vent line is vented into afume hood.Measuring hydrogen gas flowsDo not measure hydrogen together with air or oxygen. This can create explosivemixtures that may be ignited by the automatic ignitor.To avoid this hazard:Turn the automatic ignitor off before you begin.Always measure gases separately.When measuring gas flows on a detector using hydrogen for the detectorflame or carrier gas, measure the hydrogen flow separately. Never allowan air stream to enter when hydrogen is present in the flow meter.Micro-Electron Capture Detector (µECD)The µECD contains a cell plated with 63Ni, a radioactive isotope. The betaparticles released at the energy level in the detector have little penetratingpower—the surface layer of the skin or a few sheets of paper will stopmost of them—but they may be hazardous if the isotope is ingested orinhaled. For this reason, handle the cell with care. Cap the detector inletand outlet fittings when the detector is not in use. Never introducecorrosive chemicals into the detector. Vent detector exhaust outside thelaboratory environment.Refer to the safety documentation provided with the detector forimportant details about safety, maintenance, and compliance with localgovernment regulation.Materials that may react with the 63Ni source, either to form volatile products or tocause physical degradation of the plated film, must be avoided. These materialsinclude oxidizing compounds, acids, wet halogens, wet nitric acid, ammoniumhydroxide, hydrogen sulfide, PCPs, and carbon monoxide. This list is not exhaustivebut indicates the kinds of compounds that may cause damage to 63Ni detectors.In the extremely unlikely event that the oven or the detector-heated zone should gointo thermal runaway (maximum, uncontrolled heating in excess of 400 °C) and thedetector remains exposed to this condition for more than 12 hours, take thefollowing steps:1After turning off the main power and allowing the instrument to cool to roomtemperature, cap the detector inlet and exhaust vent openings. Wear disposableplastic gloves and observe normal laboratory safety precautions.2Contact your local Agilent Technologies sales office or distributor for ECD disposal instructions3Include a letter stating the condition of abuse.It is unlikely, even in this very unusual situation, that radioactive material willescape the cell. However, permanent damage to the 63Ni plating within the cell ispossible; therefore, the cell must be returned for exchange.Do not use solvents to clean the µECD.You may not open the µECD cell unless authorized to do so by your local nuclear regulatory agency. Do not disturb the four socket-head bolts. These hold the cell halves together. United States customers removing or disturbing them is a violation of the terms of the exemption and could create a safety hazard.When handling µECDs:•Never eat, drink, or smoke.•Always wear safety glasses when working with or near open µECDs.•Wear protective clothing such as laboratory jackets, safety glasses, and gloves, and follow good laboratory practices. Wash hands thoroughly with a mild nonabrasive cleaner after handling µECDs.•Cap the inlet and outlet fittings when the µECD is not in use.•Connect the µECD exhaust vent to a fume hood or vent it to the outside. See the latest revision of 10 CFR Part 20 (including AppendixB), or the applicable state regulation. For other countries, consult withthe appropriate agency for equivalent requirements.Agilent Technologies recommends a vent line internal diameter of 6 mm (1/4-inch) or greater. With a line of this diameter, the length is not critical.Fuses and BatteriesThe GC requires fuses and batteries for proper operation.
