Lifecycle Approach to Cleaning Validation


Published on

In this presentation from IVT's 4th Annual Validation Week EU, Paul Pluta, discussed the differences between the traditional approach to cleaning validation and the lifecycle approach, applicable regulatory guidance, current industry trends, the necessary phases of the lifecycle approach (design and definition, cycle development, validation, and implementation), how to continously monitor the process, change control, and common obstacles to compliance.

Lifecycle Approach to Cleaning Validation

  2. 2. MANUAL CLEANING -- Do you really know what is happening?Q to operator: “Why is there so much foam in the tub?”A: “I put in extra soap because the equipment was really dirty.”Q to operator: “Why is there powder on the (clean) equipment?”A: “No problem -- We’ll get the residue when we set up ”A: No problem -- We ll get the residue when we set up.Q to operator: “Why don’t you follow the cleaning procedure?”Q to operator: Why don t you follow the cleaning procedure?A: “The cleaning procedure really doesn’t work.”ABOVE NOT ACCEPTABLE – TRAINING NEEDED2
  3. 3. MANUAL CLEANING -- Do you really know what is happening?Q to operator: “Why is there powder on the clean equipment?”p y p q pA: “It’s clean enough.”Q to QA (equipment inspection person): “Did you approve that the equipmentis clean?”A: “It’s clean enough.”Q to management: “Do you know that your equipment is not clean?”A: “It’s clean enough.”Q to operator: “You cleaned the gasket with pure soap – this is not theprocedure? Also it is dangerous – these are corrosive chemicals.”A: “That is the only way to get it clean.”Q: “So why don’t you tell someone to change the procedure?”A: “We don’t have time.”ABOVE NOT ACCEPTABLE – TRAINING NEEDED3
  4. 4. MANUAL CLEANING -- Do you really know what is happening?Q to management: “Did you finish cleaning the equipment? We arehere to swab for cleaning validation.”A ( dl ) “W l d th i t th ti th tA (very proudly): “We cleaned the equipment three times so that wewon’t have any problems.”Q to validation person: “Did you know that the manufacturing peoplealways clean the equipment multiple times before it is swabbed?”A: “Sure, we knew.Q: “Why didn’t you stop this?”A: “These people are our friends. We have to work with these people.”ABOVE NOT ACCEPTABLE – TRAINING NEEDED4
