More info
Description / Abstract:
These requirements are supplementary to other applicable requirements in the Standard for Safety for Vacuum Cleaners, Blower Cleaners, and Household Floor Finishing Machines, UL 1017.
These requirements apply to commercial or industrial portable WET-TYPE DUST COLLECTORS and commercial or industrial portable WET-TYPE VACUUM CLEANERS for the collection of combustible metal dust in the production, processing, finishing, handling, recycling, storage and use, including operations, such as grinding, sanding, cutting, machining and additive manufacturing, of metals and alloys in a form capable of combustion or explosion as defined by NFPA 484.
These requirements apply to products for use in ordinary (unclassified) locations. Equipment intended for use in hazardous locations, as defined in the National Electrical Code, ANSI/NFPA 70, are covered by UL 1203.
Products with current-carrying hoses and motorized nozzles for collection of combustible metal dust are not covered by these requirements.
These requirements apply only to a specific type of appliance, such as a vacuum cleaner or dust collector, if the requirement is so identified by specific reference to the type involved. Absence of such specific reference or use of the term ″appliance″ indicates that the requirement applies to all appliances covered by this standard.
