Pails
Solvent and oil-based fluids: follow local
codes and regulations. Use only conductive
metal pails, placed on a grounded surface
such as concrete.
Do not place pail on a non-conductive surface
such as paper or cardboard which interrupts
grounding continuity.
Always ground a metal pail: connect a
ground wire to the pail. Clamp one end to the
pail and the other end to a true earth ground
such as a water pipe.
