ALLOW few students to respond WRITE their answers on flip chart/ board CLARIFY and SUMMERIZE by using the content bellow • Definition of zoning o Is the process of separating an area (building or room, a locked cupboard, a refrigerator, a freezer, or a cold room), which should provide distinct environmental conditions, a certain level of safety or the required level of security. STEP 3: Zoning of Stock within the Store (20 minutes) • Medicines and medical supplies must be stored in a zone/part of the store with the correct combination of temperature and security as well as the required level of safety and security. This initial zoning process is the most basic way in which supplies can be arranged. • Follow to the extent possible, the product manufacturer‘s storage conditions • If no specific storage conditions are given, normal storage conditions apply. Normal storage conditions for medicines have been defined as storage in dry, well-ventilated premises at temperatures of 15ᴼC-25ᴼC , or depending up climatic conditions, up to 30ᴼC (WHO 2003). • The 15ᴼC to 25ᴼC-30ᴼC temperature zone is assumed to be air-conditioned and humidity controlled. In temperate climates this temperature range can be achieved without air- conditioning, but humidity control may still be necessary • Each storage zone should have at least one thermometer, and temperature should be recorded daily at the hottest time of the day. • Storage at uncontrolled room temperature: o Many stocks can be safely stored at uncontrolled room temperature. • Cold storage: o example of drug products which usually require refrigeration: insulin Ergometrine for injection vaccines, antitoxins sera and blood products test kits/diagnostic tests 41 o These must be stored in refrigerator or cold chains because their potency depends on cold storage. • Secure storage: o This is necessary to protect drug products, which have higher risk of theft, or to comply with national laws o Narcotics and other controlled drugs should be kept in a secure room, a safe or steel cupboard/ cabinet to prevent access to unauthorized persons o The keys to the secure store should be kept in a safe by a store in-charge o Entry to the store must be controlled or restricted • Flammables e.g. alcohol/spirit, halothane, ether, must be stored in special buildings or rooms. A separate building is the best because it greatly reduces the risk of a fire spreading to the main store. The flammables store must be well ventilated and fire proof; use water paints on the walls. STEP 4: Criteria for Establishing Zones within a Store (10minutes) • The selection of the storage zones (as well as suitable storage equipment) is determined by various criteria: o Required storage temperature and humidity o Size of the product o Volume of batch o Weight of batch o Requirement for special storage equipment o Dangers posed by products o Required level of security o Requirements of national legislation • The required level of security for internationally controlled drug products is determined by national legislation and regulations. • The level of security will also depend on the risk of theft which may be high for internationally controlled drug products as well as antibiotics, for example. • The number of items requiring specific storage conditions as well as their average stock levels will determine the required size each zone should have. For example a medical storage facility may require only a small steel safe or a reinforced vault for storage of internationally controlled drug products. Cold chain loads may require only a single refrigerator or require a walk-in cold room. • Every product must be put away in the zone with the storage conditions recommended by the manufacturer and indicated on the packaging as well as according to the requirements by national drug legislation. • While the storage in refrigerators or locked rooms leaves no choice, many health care stock items can be stored on floor pallets or on shelves. This choice is determined by the volume of batch of each product. • Possible changes in the need for different zones as well as the capacity of individual zones should be taken into account from the very beginning. The zoning plan should be as flexible as possible to allow future changes such as extension of the cold room
