515.3 Class I Locations. Table 515.3 shall be applied where Class I liquids are stored, handled, or dispensed and shall be used to delineate and classify bulk storage plants. The class location shall not extend beyond a floor, wall, roof, or other solid partition that has no communicating openings. [30:8.1, 8.2.2]
From the NFPA 2008 NEC Handbook (I highly recommend you purchase a copy):
"Table 515.3 is extracted from Table 8.2.2 of NFPA 30-2003, Flammable and Combustible Liquids Code. Section 7.3.4.5 of NFPA 30, as referenced in the first two items in column 1 of Table 515.3, states:
To answer your question, there are several different scenerios and they range from 3' to 5'. If you use 5', you should be OK. :smile:

7.3.4.5 Where equipment such as dispensing stations, open centrifuges, plate and frame filters, and open vacuum filters is used in a building, the equipment and ventilation of the building shall be designed to limit flammable vapor–air mixtures under normal operating conditions to the interior of equipment and to not more than 1.5 m (5 ft) from equipment that exposes Class I liquids to the air. [NFPA 30-2003: 7.3.4.5]"
The handbook goes on with several illustrations that will make the purchase a good deal.

Remember that beyond the Cl 1 Div 1 boundary the classification goes to Class 1 Div 2 for a considerable distance. You can't go directly from Div 1 to non-classifed.

Any help is apprecitiated.
