· Review and maintain appropriate alarm, warning, shutdown, and evacuation logic for hazardous gas systems.

· Support integration of gas detection systems with FMCS, fire alarm, emergency shutdown, exhaust, and production equipment where applicable.

· Verify critical safety interlocks, permissives, alarm setpoints, emergency shutoff functions, and fail-safe conditions.

· Participate in risk assessments, HAZOP/JHA reviews, MOC activities, incident investigations, and corrective/preventive actions related to Gas & Chemical systems.

· Work closely with EHS to ensure hazardous gas and chemical systems are operated and maintained in accordance with site safety requirements.

Preventive & Corrective Maintenance

· Develop and maintain preventive maintenance requirements for Gas & Chemical equipment.

· Provide engineering support for troubleshooting equipment failures, abnormal pressure/flow, gas detection alarms, exhaust issues, supply interruptions, leakage, valve failures, instrumentation faults, and control system abnormalities.

· Perform root cause analysis for recurring failures and production-impacting incidents.

· Develop and track corrective and preventive actions (CAPA).

· Analyze equipment performance and maintenance history to improve system reliability.

· Support calibration, functional testing, leak testing, pressure testing, and verification of critical instrumentation and safety devices.

Controls, Monitoring & FMCS

· Define and maintain required operating parameters, alarms, trends, and monitoring points within FMCS/TGMS.

· Review alarm history and system trends to identify developing equipment or process issues.

· Establish appropriate warning and critical alarm thresholds.

· Support control logic development for automatic shutdown, isolation, changeover, backup supply, and emergency response.

· Ensure critical Gas & Chemical operating data is available to Facility Operations for effective system monitoring.

Project Engineering & Commissioning

· Review Gas & Chemical designs for new installations, production expansion, Phase 2 projects, and system modifications.

· Review P&IDs, equipment layouts, piping specifications, control philosophy, cause-and-effect logic, equipment specifications, and vendor drawings.
