    • For surface disinfectant used during other activities, prepare and add the disinfectant in the spray bottles. Label these dilute disinfectant bottles with the details: Name, Date of preparation, Preparation number, prepared by and Use before Date. This disinfectant shall be used up to the next day of preparation of the fresh disinfectant.
    • For LAF workbenches use 70% IPA for cleaning and disinfection.
    • Use the sterillium as it is without dilution.
    • Use the defined volume of disinfectants concentration solutions and diluent as per Table-2, for 1000 ml of dilute disinfectant preparation.
    • Record the preparation of disinfectants as per Annexure no.
