Preventive Measure 5
If it is not possible to use a conductive waste liquid container, take the following precautions:
• Ensure that the end of the inflow tubing is always submerged inside the container. Also, place some
type of grounded metal object, such as a ground wire connected to the instrument, into the liquid.
!CAUTION
The above precaution will be ineffective for low conductivity (less than 10
−10
S/m) liquids.
• Use as small a container as possible to minimize damage in the event of fire.
• Keep the room at a proper humidity.
Ambient humidity exceeding 65 % will prevent static.
