ABSTRACT:
Safety device for an electrostatic painting plant using liquid coating products which are very electrically conductive, such as hydrosoluble paints or liquid enamel. An electrically insulating enclosure surrounds the container for the liquid coating material and has a latching device enabling the opening of the enclosure cover to be carried out only in a predetermined sequence, the first step of which causes the grounding of the paint container. The arrangement is such that the container can be disconnected from the ground only after the insulating enclosure cover has been replaced.
