Electrical equipment can cause explosions in environments where explosive concentrations of combustible dust are present. | ||||||||
The National Fire Protection Association (NFPA) establishes area classifications based on classes, divisions, and groups that delineate the hazardous conditions in a specific area. In a grain handling facility, this may include enclosed areas of the facility such as tunnels, intermediate floors of a headhouse, gallery floors, boot pits, etc. This may be continuous, intermittent, or on a periodic basis. This may include situations where an ignitable mixture could be produced by a mechanical failure or abnormal machinery operation. An example of Class II, Division 1 is a grain receiving tunnel with an open conveyor. Use appropriately rated electrical tools in these areas, and make sure that portable or fixed electrical equipment and systems do not pose an ignition source.
