Standard Operating Procedure for Responding to Power Outages in Manufacturing Areas
1) Purpose
The purpose of this SOP is to establish clear procedures for responding to power outages in manufacturing areas to minimize disruption, ensure personnel safety, and protect equipment and processes.
2) Scope
This SOP applies to all employees, supervisors, and technical teams in the facility and covers response actions during planned and unplanned power outages, including the use of backup systems and post-outage recovery.
3) Responsibilities
- Supervisors: Coordinate team activities during a power outage and ensure compliance with this SOP.
- Maintenance Team: Inspect and restore power systems, including backup generators and UPS (Uninterruptible Power Supply) units.
- Safety Officers: Monitor safety protocols during outages to prevent accidents and ensure emergency lighting is operational.
- Operators: Follow procedures to safely shut down and restart equipment as required.
4) Procedure
4.1 Immediate Actions During a Power Outage
- Identify the Outage:
- Confirm the power outage by checking facility systems and external sources (e.g., utility providers).
- Determine whether the outage is localized or facility-wide.
- Ensure Personnel Safety:
- Activate emergency lighting to prevent accidents in dark areas.
- Ensure all personnel remain calm and follow instructions from supervisors.
- Communicate the Outage:
- Inform all employees about the power outage via public address systems or

other communication tools.
Notify the maintenance team and facility manager immediately.
Secure Equipment:
- Shut down non-critical equipment to prevent damage when power is restored.
- For critical systems, activate backup power sources, such as UPS units or generators.
4.2 Activation of Backup Systems
- Switch to Generators:
- Maintenance teams must activate backup generators to restore power to critical systems.
- Ensure generators have sufficient fuel and are operating within safety parameters.
- Use Uninterruptible Power Supplies (UPS):
- For short-term outages, rely on UPS systems to maintain power for essential equipment.
- Monitor UPS performance to ensure continued functionality until full power is restored.
- Prioritize Critical Areas:
- Allocate backup power to critical systems, such as HVAC, fire safety, and essential production equipment.

4.3 Monitoring During the Outage
- Inspect Systems:
- Regularly check generators, UPS units, and other systems to ensure they are functioning properly.
- Manage Operational Processes:
- Pause production processes that cannot operate safely without full power.
- Secure perishable or temperature-sensitive materials using backup HVAC systems.
- Document Activities:
- Record actions taken during the outage in the Power Outage Log (Annexure 1).

4.4 Post-Outage Recovery
- Power Restoration:
- Confirm power restoration with the utility provider or facility management system.
- Gradually switch off backup systems and transition to main power supply.
- Equipment Inspection:
- Inspect all equipment for potential damage or malfunctions caused by the outage.
- Restart Operations:
- Resume production and other operations in a phased manner to prevent system overload.
- Report and Review:
- Complete a post-outage report detailing the event, response actions, and any lessons learned.
