 1.     Purpose:-                         

           To provide a procedure for the operation of Reagent Refrigerator
     2. Scope:-

This procedure is applicable to in Quality Control Department.
3. HSE Statement:-

Not Applicable.
4. Responsibilities:-

                                i)      Manager Quality Control is responsible to ensure that procedure & formats are followed entirely as approved.
                              ii)       Microbiologist is responsible to operate the instrument.
5. Materials:-

      6. Definitions:-

      6.1 Refrigerator:-
           Refrigerators designed to store laboratory products, cultures, and samples at

temperatures typically between 2 and 10 degrees Celsius (35 and 50 degrees Fahrenheit). These refrigerators typically consist of a chamber made with a corrosion-resistant (typically stainless steel) interior, minimizing the risk of adulteration, contamination, and/or corrosion of contents; internal shelving appropriate for storage, easy location, and handling of laboratory products; a compressor, condenser, evaporator, and tubing; sensors, controls, and monitors; a temperature recording chart and alarms for dependable long-term storage following laboratory standards; and an emergency power supply for both the refrigerator and alarm. 

8. Description:-
  8.1 Procedure:-
  8.1.1 Reagent Refrigerator consists of two compartments.
           Lower is Refrigerator  and upper Freezer.
8.1.2  Temperature Range for refrigerator is 4 to 8 °C and for freezer is –19 to – 25 ° C.
8.1.3  Switch On the apparatus.
8.1.4  Temperature appears on the screen.
8.1.5  Different keys are present, which are we used for the setting of temperature.
8.1.6  Take the print out and record the readings when required.
8.1.7  If the instrument does not produce required results or its response is poor then it should be labeled as “OUT OF ORDER” and should be repaired or serviced from a qualified technical person
  8.2 Cleaning:-

  8.2.1 The surfaces of the Reagent Refrigerator can be cleaned with commercially available cleaning
agents. Clean the refrigerator with soft cloth.               
8.2.2    It is important to ensure that no rust forming object comes in to contact with the chamber. If any
contamination causes rust stains on the surfaces of the chamber, such spots must be cleaned off immediately and the area should be polished.
8.2.3 The control panel, the plastic input modules and other plastic components of the Reagent Refrigerator
 must not be cleaned using scouring cleaning agents or those contained solvents.
8.2.4        Lubricate all moving parts of the door using thin silicon grease and to check that the hinge screws are tight.
8.3. Safety Precautions:-

8.3.1        Do not place any load on the floor against the side walls or underneath the ceiling of the chamber in order to ensure proper air circulation inside the chamber.
8.3.2        Always place the Reagent Refrigerator in a well ventilated area.
8.3.3        As a routine working precaution, always wear safety mask and protective gloves when operating loading and unloading the Reagent Refrigerator.

8.4. Calibration Frequency:-
                              Annually from external source.
9. Records:-
                 Daily basis temperature record for incubators and ovens.
