Standard Operating Procedure for Conducting Emergency Shutdown of Equipment
1) Purpose
The purpose of this SOP is to provide a structured procedure for safely and efficiently shutting down equipment during emergencies to protect personnel, prevent damage, and mitigate risks to the facility and environment.
2) Scope
This SOP applies to all employees, contractors, and emergency response team (ERT) members involved in the operation and maintenance of equipment across manufacturing, laboratory, and storage facilities.
3) Responsibilities
- Emergency Response Team (ERT): Execute and supervise emergency shutdown procedures.
- Supervisors: Ensure personnel are trained on emergency shutdown protocols and manage the shutdown process within their departments.
- Operators: Perform shutdown procedures as outlined in this SOP and notify supervisors during emergencies.
- Maintenance Team: Inspect equipment post-shutdown and ensure safe reactivation.
- Safety Officers: Monitor compliance with shutdown protocols and assess risks during emergencies.
4) Procedure
4.1 Identifying Emergency Scenarios Requiring Shutdown
- Critical Scenarios:
- Fire or explosion near operational equipment.
- Chemical leaks or spills in equipment areas.
- Power outages or electrical surges.
- Mechanical malfunctions posing immediate hazards.
- Natural disasters (earthquakes, floods).
- Initial Assessment:
- Operators and supervisors must assess the severity of the situation and decide whether a full or partial shutdown is necessary.

- Deactivate equipment using the designated emergency stop button or power switch.
- Isolate equipment from the main power supply by switching off circuit breakers, if required.
- For equipment handling hazardous materials, close all valves and seals to prevent leaks.
- Activate emergency containment systems, such as spill containment trays or gas absorption units.
- Activate fire suppression or ventilation systems, if available, to mitigate secondary hazards.
- Log all actions taken during the shutdown in the Emergency Shutdown Log (Annexure 1).
4.3 Post-Shutdown Activities
- Verify Safety:
- Ensure the area is safe for personnel reentry by conducting air quality checks and visual inspections.
- Confirm that all equipment is powered off and deactivated.
- Inspect Equipment:
- Maintenance teams must inspect equipment for damage and identify any necessary repairs.
- Record inspection findings in the Equipment Inspection Report (Annexure 2).
- Incident Reporting:
- Document the incident details, including the cause, affected equipment, and response actions, in the Emergency Incident Log (Annexure 3).
- Notify Regulatory Authorities:
- If required by law, report the incident and shutdown actions to regulatory bodies.

4.4 Restarting Equipment
- Pre-Restart Checks:
- Verify that all repairs and maintenance activities are complete.
- Ensure the area is free of hazards and all safety systems are functional.
- Gradual Restart:
- Follow standard operating procedures for equipment startup, monitoring for irregularities.
- Test equipment performance under supervision before resuming full operations.
