1 Introduction
Be careful when working behind the instrument. During cool-down cycles, the
WAR N IN G
GC emits hot exhaust that can cause burns.
The foreline pump can cause burns if touched when operating.
WAR N IN G
The insulation around the inlets, detectors, valve box, and the insulation cups
WAR N IN G
is made of refractory ceramic fibers. To avoid inhaling fiber particles, we
recommend the following safety procedures: ventilate your work area; wear
long sleeves, gloves, safety glasses, and a disposable dust/mist respirator;
dispose of insulation in a sealed plastic bag in accordance with local
regulations; wash your hands with mild soap and cold water after handling the
insulation.
The oil pan under the rotary vane foreline
pump can be a fire hazard
Oily rags, paper towels, and similar absorbents in the oil pan could ignite and
damage the pump and other parts of the MS.
Combustible materials (or flammable/nonflammable wicking material) placed
WAR N IN G
under, over, or around the foreline (roughing) pump constitutes a fire hazard.
Keep the pan clean, but do not leave absorbent material such as paper towels
in it.
