If you have products that need increased security, you must establish access-controlled storage. This will probably include storing the products in-
a separate locked room, cabinet, or safe, or
a locked wire cage within the storage facility.
Ideally a warning light or bell will be activated if the products are accessed improperly.
Entry to the location of the access -controlled products must be limited to the most senior storekeeper or pharmacist and one other staff member.
Limit the number of keys made for the controlled location and keep a list of people who have keys.
