Three. The transportation, storage and use of vaccines should be carried out in strict accordance with the relevant temperature requirements. In accordance with the vaccine varieties, batch classification neatly stacked, vaccine carton (box) have cold air circulation channel should be between the refrigerator and the wall. Distribution and use of vaccines in accordance with the first short term, after the long term and the same batch of vaccine according to the first storage, the first out of the principle of storage should be neat, marked packaging, the vaccine between the cold air circulation channel.

Four, improve the cold chain equipment management system, the establishment of cold chain equipment, recording various equipment name, model number, arrival time, equipment operation and maintenance; establish the record book, record of failure and maintenance. Vaccine should be done in a timely manner loss reporting procedures.

Five, cold chain equipment to do special management, regular maintenance, maintenance, temperature record. Cold chain equipment must have special maintenance, regular cleaning cleaning, 2 times a day (morning and afternoon before work) were recorded in operation of the refrigerator freezer temperature; cold pack after each use timely wipe dry ice, with timely back to the freezer frozen after.

Six, cold chain refrigerator and freezer should be placed in dry, ventilated, avoid direct sunlight, away from the heat of the place, the rear to leave space, the bottom to pad shelf, power lines and outlets should be dedicated line.
