The Committee is considering adding water mist and hybrid water mist fire protection systems into applicable sections of NFPA 34 however there are several concerns that should be addressed. Water mist systems are currently not listed for use in dipping, coating and printing processes using flammable or combustible liquids. The committee also decided there was a potential conflict with NFPA 750 and the term "hybrid water mist" as suggested in public inputs 35, 36,37, 38 and 40.

Insulators shall be kept clean and dry A separation of at least twice the sparking distance shall be maintained between the object or material being deteared and the electrodes or conductors. A sign indicating this separation distance shall be conspicuously posted near the assembly Support of Workpieces Workpieces or material being deteared shall be supported on conveyors or hangers * The conveyor shall be arranged to ensure that the workpieces or material being deteared is electrically connected to ground with a resistance of not more than 10 6 ohms (1 megohm) and that the distance required by is maintained between the workpiece or material and the electrodes at all times Workpieces or material being deteared shall be supported to prevent swinging or movement that would reduce the distance to less than that required Manual Operations. Electrostatic detearing shall not be used where the workpieces or material being deteared is manipulated by hand Electrical Safety Requirements.

Safeguards such as enclosures, fencing, railings, or other means shall be placed about the equipment or incorporated therein to ensure that isolation of the process is maintained from plant storage or personnel * Grounding Requirements. All electrically conductive objects in the process area, except those objects required by the process to be at high voltage, shall be electrically connected to ground with a resistance of not more than 10 6 ohms (1 megohm) This requirement shall apply to paint containers, wash cans, guards, and any other electrically conductive objects or devices in the area This requirement also shall apply to any personnel in the process area The equipment shall carry a prominent, permanently installed warning regarding the necessity for this grounding feature Signs.

22 Page 15 of 15 Committee Statement: Response Message: The Committee is proposing to delete this chapter because there is a general consensus within the industry that this technology is no longer used. However before this chapter is removed, the Committee is asking the industry to provide input on whether or not the technology is still in use. This process has historically been the source of a number of fires and the Committee does not want to delete the chapter if this technology is still being used. Note that (2) would need to be deleted if this Committee input becomes a first revision at the second draft meeting. Ballot Results This item has not been balloted
