Vent the GC/MS system externally to the building via an ambient-pressure
vent system, within 460 cm (15 ft) of both the GC split vent and GC/MS
foreline pump, or vent to a fume hood.
Note that an exhaust vent system is not part of the building environmental
control system, which recirculates air.
Exhaust venting must comply with all local environmental and safety codes.
