C. Maintenance and Change Control

/n

/n

- Plan and control preventive, predictive,



condition-based and breakdown maintenance during the shift without compromising safety, redundancy or customer service.

/n

- Verify approved work order, risk assessment, method statement, permit-to-work, isolation/LOTO, rollback plan, test instruments, spares and competent manpower before work begins.

/n

- Lead pre-work briefing and post-work validation; confirm system normalization, alarm clearance, removal of temporary arrangements and closure of permits and change records.

/n

- Coordinate OEMs and vendors, verify attendance and workmanship, track observations, and escalate overdue maintenance, defects and repeat failures.

/n

/n

D. Capacity, Efficiency and Customer Delivery

/n

/n

- Monitor electrical and cooling loading, operating margins and redundancy; escalate threshold breaches and emerging capacity risks.

/n

- Track shift-level energy and water performance indicators, including PUE/WUE inputs, abnormal consumption and avoidable simultaneous or unloaded operation.

/n

- Coordinate approved power provisioning, energization, commissioning, capacity augmentation and customer delivery activities.

/n

- Manage customer calls, service requests, incident communications and remote-hands support within approved scope and access controls.

/n

- Protect customer confidentiality and ensure activities in white space are executed with authorization, escort, ESD controls and accurate closure records.

/n

/n

E. Safety, Compliance and Audit Readiness

/n

/n

- Enforce electrical, mechanical, work-at-height, hot-work, confined-space, lifting and chemical-safety controls applicable to activities during the shift.

/n

- Ensure permits, LOTO, PPE, toolbox talks, competency checks and emergency arrangements are in place; exercise stop-work authority for unsafe conditions.

/n

- Maintain readiness for statutory, customer and management audits; retain complete logs, checklists, test records, permits and maintenance evidence.

/n

- Follow site requirements for ISO management systems, environment, health and safety, security and applicable statutory interfaces; immediately report non-compliance.

/n

- Conduct or participate in emergency drills, post-drill reviews and action closure.

/n

F. Team, Vendor and Shift Handover

/n

/n

- Brief, coach and assess shift personnel on assigned tasks, site procedures, emergency response and equipment operation.

/n

- Coordinate effectively with security, safety, IT/network, projects, customer delivery, facility management, OEMs and service partners.

/n

- Prepare daily, weekly and monthly operating inputs, including alarms, incidents, maintenance, capacity, efficiency, safety, risks, vendor performance and pending actions.
