5.0 Procedure:  

5.1. General Instructions:

5.1.1. Operation and usage of OFCB for sampling shall be as per respective operation SOP.

5.1.2.   Sampling shall be done by trained QC persons only.

5.1.3.   Ensure the OFCB is switched ON, cleaned and required differential pressure is shown on the Magnehelic gauge of the OFCB.

5.1.4.   Refer MSDS of the material for use of respective PPE, precautions during handling and spillage of material during sampling.

5.1.5.   OFCB shall be switched “OFF” after completion of all sampling activities.

5.1.6.   No sampling activity shall be performed in case of power failure of the OFCB or it is under breakdown condition/maintenance or any abnormal reading is observed in the pressure gauge. Immediately inform the engineering department for corrective action.

5.3.8. Same procedure shall be followed for other containers.

5.3.9. In case of solvent spillage, clean the OFCB as per the procedure given in SOP.

5.3.10. Checklist for sampling of raw material shall be completed.

5.3.11. On completion of all sampling activities, “sample for analysis” label shall be affixed on all sampled containers and then the sampled container shall be placed in a polythene bag and “sample for analysis” label shall be affixed on the poly bag also.

5.4. Documentation: Record for usage of OFCB and pressure differential readings shall be maintained in respective format.         

5.5. Exiting the Sampling room:

5.5.1. Sampled containers shall be kept in the tray and the same shall be carried by the person through the man entry only.

5.5.2. Disposable gloves, disposable mask, disposable shoe covers and disposable cap shall be discarded properly in the bin.
