 Preventing Static Electricity Accidents
The best way to prevent static electricity accidents is simply to prevent the occurrence and accumulation of
electrostatic charges.
!CAUTION
• It is important to take multiple preventive measures without fail.
• If large amounts of flammable solvents are collected in a large container, implement
preventative measures 1, 2, and 3 below.
Preventive Measure 1
Use a metal container for waste liquid, and ground the container.
This will ensure that the electrical charges of the container and liquid pass to the ground.
Accessories for this measure
!CAUTION
• Be sure to ground the metal waste container properly.
If the grounding wire is not properly attached or connected to the ground, static electricity can build up
in the container.
• Be sure to verify, using a tester, that the waste container is properly grounded.
Some metal containers have surfaces that are oxidized or laminated. Such a container may not conduct
electricity.
• If the liquid to be drained into the waste container is virtually non-conductive (10
−10
S/m
or less), it will be necessary to add properly conductive, and therefore safe, liquid to the
tank.
This conductive liquid may be added beforehand.
(1) Grounding wire with clip Part No. 228-21353-91
(2) 18-L metal container Part No. 038-00044
(3) 4-L metal container Part No. 038-00043-01
Connect clip to metal parts.
Reduce the opening with a cap.
18-L metal container (preferably plated)
Connect to ground terminal or other grounding point of
the instrument to ground metal container.
Liquid's static will be conducted through container to
ground.
