Operational Precautions and LimitationsSystem User Guide 4500 Series of InstrumentsRUO-IDV-05-0264-A 13 of 138Ventilation PrecautionsThe venting of fumes and disposal of waste must be in accordance with all federal, state,provincial, and local health and safety regulations. Use the system indoors in a laboratory thatcomplies with the environmental conditions recommended in the Site Planning Guide for thesystem.The source exhaust system and roughing pump must be vented either to an external fume hoodor to an external exhaust system as recommended in the Site Planning Guide for the system.Environmental PrecautionsUse qualified personnel for the installation of electrical mains, heating, ventilation, and plumbingsupplies and fixtures. Make sure that all installations follow local bylaws and biohazardregulations. For more information about the required environmental conditions for the system,refer to the Site Planning Guide.WARNING! Asphyxiation Hazard: Take care to vent exhaust gases properly. Thevent tubing must be secured with clamps. The use of mass spectrometers withoutadequate ventilation to outside air might constitute a health hazard. In addition,certain procedures required during the operation of the mass spectrometer mightcause gases to be discharged into the exhaust stream. Under these conditions,inadequate ventilation might result in serious injury.WARNING! Toxic Chemical Hazard, Biohazard, Radiation Hazard: Makesure that the mass spectrometer is connected to the local exhaust systemand ducted to control hazardous emissions. The system should only beused in a well-ventilated laboratory environment in compliance with localregulations and with appropriate air exchange for the work performed.Some jurisdictions recommend 4 to 12 air changes per hour inlaboratories.WARNING! Potential Toxic Chemical Hazard, Biohazard, RadiationHazard: Do not operate the mass spectrometer if the source exhaust drainand roughing pump exhaust hoses are not properly connected to thelaboratory ventilation system. Perform a regular check of the exhausttubing to ensure that there are no leaks.DANGER! Explosion Hazard: Do not operate the system in an environmentcontaining explosive gases. The system is not designed for operation in anexplosive environment.WARNING! Asphyxiation Hazard: Take care to vent exhaust gases properly. Theuse of mass spectrometers without adequate ventilation to outside air mightconstitute a health hazard. In addition, certain procedures required during theoperation of the mass spectrometer might cause gases to be discharged into theexhaust stream. Under these conditions, inadequate ventilation might result inserious injury.
