Supposed my company water plant work between 25-12-20 to 31-12-20 major work like multiculumn PSG work and EDI work so required change control or breakdown maintenance memo? After completion of work starts the validation of water plant.
- Initiate planned deviation.
- Initiate Work permit
- Evaluate the major change if any
- Complete analysis of Steam and water from EDI before release for use.
- 2 weeks monitoring of water system
for already validated system facility, not need re-validation.
