Take additional precautions if your roll coating operation uses a liquid that has a flashpoint below 140°F (60°C).

This section applies to the processes of roll coating, roll spreading, or roll impregnating that use a liquid having a flashpoint below 140°F (60°C). Material may be passed directly through a tank or over the surface of a roller that revolves partially submerged in the liquid.
You must prevent sparks from static electricity by:
(1) Bonding and grounding all metallic parts (including rotating parts) and installing static collectors; or
(2) Maintaining a conductive atmosphere (one with a high relative humidity, for example) in the vapor area.
