Many parts are dangerously hot

Fibrous insulation

Getting Started
Many parts of the GC operate at temperatures high enough to
cause serious 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 box
You should always cool these areas of the GC to room
temperature before working on them. They will cool faster if you
first set the temperature of the heated zone to room
temperature. Turn the zone off after it has reached the setpoint.
If you must perform maintenance on hot parts, use a wrench
and wear gloves. Whenever possible, cool the part of the
instrument that you will be maintaining before you begin
working on it.
Be careful when working behind the instrument. During cool-down
cycles, the GC emits hot exhaust which can cause burns.
The insulation around the inlets, detectors, valve box, and the
insulation cups 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
• Wash your hands with mild soap and cold water after
handling the insulation.
