5.1           Check the performance of the HEPA filter by the following methods:

5.1.1        DOP test     : To be performed by external agency.

5.1.2        Particulate count:    To be performed by external agency

5.1.3        Velocity measurement: To be performed by external agency

               Frequency    : Once in a year.

5.2           Plate count method :

5.2.1           Expose soya bean casein digest agar & Sabouraud chloramphenicol agar plates in  

   Biosafety cabinet for 2 hours.

5.2.2           Incubate soya bean casein digest agar plates at 35-37°C for 24 hours and Sabouraud  

              chloramphenicol agar plates at 20-25°C for 72-96 hrs.

5.2.3           Observe the plates & count the no. of colonies found. Record the observations in the
