1. Purpose
Define a controlled weekly inspection process for standby generator systems to verify general readiness, visible condition, alarm status and supporting infrastructure before an emergency start is required.
2. Scope
Applies to routine weekly visual and operational readiness checks of standby generator systems, generator rooms or external generator enclosures, associated local controls, starting systems, fuel systems and visible supporting infrastructure.
This example does not replace manufacturer requirements, statutory inspection requirements, local electrical regulations, site-specific procedures or the requirements of the authority having jurisdiction.
3. Preconditions
- ☐ Inspection is part of an approved routine maintenance schedule
- ☐ Generator area is accessible and safe to enter
- ☐ Required PPE and site access permissions are available
- ☐ No active emergency event is in progress
- ☐ Monitoring system is available for alarm verification
- ☐ Latest maintenance log or CMMS record is available
4. Responsibilities
| Role | Responsibility |
|---|---|
| Operations Technician | Perform inspection, record findings and report exceptions. |
| Shift Lead / Facility Responsible | Review exceptions, confirm required follow-up and escalate if needed. |
| Maintenance Vendor / Specialist | Investigate and correct technical faults outside normal operator scope. |
| Operations Manager | Ensure inspection frequency, records and governance are maintained. |
5. Execution Procedure
| Step | Room/Tag | Action | Verification | Sign-1 | Sign-2 |
|---|---|---|---|---|---|
| 1 | GEN-ROOM / GEN-001 | Confirm the generator area is accessible, clean and free from obstruction. | Access route, working space and emergency exits are clear. | ||
| 2 | GEN-001 | Inspect generator enclosure or room for visible damage, water ingress, unusual smell or signs of leakage. | No visible damage, fluid leak, fuel smell or abnormal condition observed. | ||
| 3 | GEN-001 / LOCAL PANEL | Check local controller status and confirm generator is in the approved automatic/standby mode. | No active alarm, warning or disabled automatic start condition present. | ||
| 4 | FUEL SYSTEM | Check visible fuel level indication and inspect accessible fuel lines, valves and containment areas. | Fuel level within site-defined minimum and no visible fuel leak observed. | ||
| 5 | ENGINE / COOLING | Check visible coolant level indication, radiator area, hoses and ventilation path where accessible. | Cooling system appears normal and ventilation path is unobstructed. | ||
| 6 | ENGINE / LUBRICATION | Check visible oil level indication or local status indication according to site practice. | Oil condition/status appears within approved operating range. | ||
| 7 | BATTERY / CHARGER | Inspect starting batteries, charger status and visible terminals for abnormal condition. | Charger normal, no visible corrosion, swelling, leakage or loose connection observed. | ||
| 8 | ATS / MONITORING | Verify generator and transfer system status in monitoring or BMS/CMMS where available. | Status matches local inspection and no unresolved alarm is present. | ||
| 9 | GEN-001 | Record runtime hours, visible alarms, fuel level/status and inspection findings. | Inspection record completed in logbook or CMMS. | ||
| 10 | GEN-001 | Report any exception, abnormal condition or missing inspection access to responsible role. | Exception recorded and follow-up owner assigned. |
6. Risk Considerations
Weekly generator inspection is normally a low-impact operational activity, but it supports a high-criticality function. Missed defects may remain hidden until the generator is required during a utility failure or transfer event.
- Do not change operating mode unless authorized by the site procedure.
- Do not reset alarms without understanding and recording the cause.
- Do not open energized panels unless qualified and authorized.
- Report fuel, oil, coolant, battery or exhaust abnormalities immediately.
- Keep access routes and ventilation paths clear.
7. Rollback / Exception Handling
This inspection should not normally alter the generator operating state. If an unintended change occurs, restore the system to the approved standby condition only if qualified and authorized to do so.
If the generator cannot be confirmed available, or if automatic start readiness is uncertain, escalate immediately according to the site escalation process and record the condition as an operational exception.
8. Post Verification
- ☐ Generator remains in approved standby/automatic mode
- ☐ No unresolved alarms or abnormal local indications remain unreported
- ☐ Fuel, coolant, oil and battery status checked according to site practice
- ☐ Generator room or enclosure left secure and accessible
- ☐ Inspection record updated in logbook, CMMS or approved system
- ☐ Exceptions escalated and follow-up ownership assigned
9. Operational Notes
A weekly inspection should be treated as an early-warning control, not as a substitute for periodic functional testing, load testing, manufacturer service, fuel quality management or statutory inspection requirements.
Emergency and standby power systems are commonly governed by local regulations, manufacturer instructions and standards such as NFPA 110 where applicable. NFPA 110 covers installation, maintenance, operation and testing requirements for emergency power supply systems, and its purpose is maximum system reliability. :contentReference[oaicite:1]{index=1}
Key principles: controlled inspection, visible readiness, accurate records, exception escalation and verified standby state.
