Preparation, Approval and Control of Standard Cleaning Procedures for equipments

  • Preparation, Approval and Control of Standard Cleaning Procedures for equipments
  • OBJECTIVE :            
  • To  lay  down  the  guidelines  for  the  preparation,  approval and control of Standard Cleaning  Procedure (SCP) for all the applicable equipments.
  • All the personnel  involved in the cleaning of equipments.
  • Heads of concerned departments to ensure compliance.
  • Every   equipment  shall  be  cleaned  and  certified  as  per  the respective  Standard  Cleaning  Procedure  (SCP) as applicable for that particular equipment.
  • Every SCP shall be validated as per the requirement.
  • Different   cleaning   procedures   shall   be   followed   depending   upon   the equipment  status i.e., whether  the  cleaning  is  between  batches  of  same product or between batches of product containing same drug substance but of different strengths or different product (product changeover) etc., for all the process equipment’s.
  • Based on the above consideration three types of cleaning procedures have been described, for process equipment’s, viz.
  • Type A Cleaning Procedure (Vacuuming and dry wiping)
  • Type B Cleaning Procedure (Vacuuming  and washing with potable water followed by purified water unless otherwise specified in the respective SCP)
  • Type C Cleaning Procedure (Washing with detergent solution then potable water, then Purified water and finally with purified water unless otherwise specified in the respective SCP).
  • The decision about the type of cleaning to be carried out for all the process equipments i.e., whether Type A, Type B or Type C can be made with the help of ‘Standard Cleaning Procedure Type Selection Guide’ Annexure-1.
  • All the cleaning details shall be entered in the Equipment Usage and Cleaning Logbook (Annexure-4) as applicable.
  • SCPs are to be generated by computer on the format known as ‘Standard Cleaning Procedure’ (annexure-2). Guidelines for filling the format are asdescribed below.
  • SCP No :                                    
  • This is a unique number given to each SCP. This number consists of nine characters as described below:
  • The first character is ‘C’ which denotes cleaning.
