Reliability & Continuous Improvement

• Track/communicate leading indicators (abnormal readings, repeat alarms, vibration/noise changes, leaks, degraded performance).

• Participate in root cause analysis and improvement actions to reduce downtime, energy waste, and recurring failures.

DECISION MAKING AUTHORITY

• Take immediate actions to stabilize utilities and protect personnel, product, and equipment during upsets.

• Escalate conditions requiring shutdown, isolation, or emergency response per site procedures.
