I'm working on a project and wanted to know the Code Section stating there must be a 3 foot clearance for all electrical from the hazard area.
 
If you are talking about working clearances, as noted 110.26 although the requirement can be greater than 3 ft. If you are talking of distance from a hazardous location such as paint spray or gas dispensing the required distances vary depending on the hazard and other factors.
I believe to answer your question, a lot more information is needed.

They are storing flammable and combustible liquids in the structure and want to install an electric strike on the door - this product is not rated for hazardous locations. Being on the door would then place it within the hazard area.
 
If the area is being used for storage ONLY, with all containers always closed, the area is not classified as hazardous.
 
If the building has electrical components, an engineer should determine the Classification of the area(s) of the building. Once that classification is determined, you can make a more informed decision.
