- An Alarm Response Matrix (What to do for every alarm).
- Training records.
Step 4: Validate Performance
Run validation tests. If your system claims it can detect a 5 gallon-per-minute leak, prove it with a controlled release of water or simulated data. API RP 1175 (Recommended Practice 1175) is a
Step 5: Management Review
Annually, senior leadership must review the LDP KPIs and approve changes to the program.
