I have read the modules of the SQF code that apply to Storage & Distribution. My boss insists there is a rule regarding pallets being stacked no closer than 18 inches to the wall. It is something I vaguely remember reading somewhere, but I didn't find any mention of it in Modules 2 and 12. Can anyone tell me where it speaks to that in the SQF Code? I need to write the SOP, but I can't find a reference anywhere. So I'm stuck.
