Although segregation of materials by systems is acceptable,appropriate specific storage conditions, such as low temperature or controlled humidity, must be provided. Receivingareas, where materials are unloaded from delivery transportation, are an access point for airborne contamination, such as dirt, dust, insects, vermin, birds, and even engine fumes, from the delivery vehicles themselves. Where possible, these access points should be protected by flexible curtains to minimize the gap between the truck and the physical facility to the outside when vehicles are unloading; air curtains between the receiving bays and the warehouse proper may also be used to provide additional protection to the warehouseenvironment. Insect and rodent traps are commonly required.
