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.
