Examples of Detection Controls That Serve Different Functions
| Examples of Detection Controls | Potential Usefulness |
|---|---|
| An in-process control test for impurities and related substances | Unacceptable levels of impurities and related substances can be detected during the process step in which they are generated and action can be taken to reduce them at an early stage. |
| Visual inspection of filled vials | Glass, foreign matter, and other contaminating materials in filled vials can be detected before the release of the batch. |
| Second person checks on a batch record | A check by a second operator of the correct execution of a step in a batch record can detect errors and non-compliances in a process before their effects are realized. |
| Increased inspection activity during packaging operations | An increased level of product inspection during packaging processes can increase the detectability of defects. |
| Independent high temperature alarm switch | Useful where temperature has been defined as a critical process parameter in that process step. |
