Subsection 3.3.6. applies to the storage of products, whether raw or waste materials, goods in process, or finished goods.
This Subsection does not deal with products or materials that are directly supplied to appliances, equipment or apparatus through piping, hose, ducts, etc. For example, gas cylinders that are mounted on propane barbeques are not covered by Subsection 3.3.6. since they are considered to be “in use” as opposed to “in storage”.
The design requirements contained in Subsection 3.3.6. reflect some, but not all design requirements contained in Division B of the Fire Code as it relates to the design of hazardous areas. Designers are advised to refer to the Fire Code for any other design requirements that may apply to their circumstances.
