Standard Operating Procedure for Incident Reporting and Investigation for Hazardous Materials

1) Purpose

The purpose of this SOP is to establish a structured process for reporting, documenting, and investigating incidents involving hazardous materials to identify root causes, mitigate risks, and prevent recurrence.

2) Scope

This SOP applies to all hazardous material-related incidents, including spills, leaks, exposures, fires, explosions, and near-misses within laboratories, warehouses, production facilities, and during transportation.

3) Responsibilities

• Employees/Operators: Immediately report incidents involving hazardous materials to supervisors and safety officers.
• Supervisors: Ensure incidents are documented and initiate immediate control measures.
• Safety Officers: Investigate the incident, determine root causes, and recommend corrective actions.
• Management: Review investigation reports and ensure implementation of preventive measures.

4) Procedure

4.1 Incident Categories

1. Types of Incidents:
   • Spills and Leaks: Uncontrolled release of hazardous materials.
   • Exposures: Direct or indirect contact with hazardous materials (skin contact, inhalation, ingestion).
   • Fires and Explosions: Combustion or ignition of flammable substances.
   • Near Misses: Events that could have resulted in an incident but did not cause harm.

4.2 Incident Reporting

1. Immediate Response:
   1. Upon identifying an incident, employees must:
      • Alert nearby personnel and evacuate the area, if necessary.
      • Activate emergency alarms if there is a risk of fire, explosion, or major exposure.
      • Seek medical assistance if there is any injury or chemical exposure.

Reporting the Incident:
1. Employees must report the incident immediately to the supervisor or Safety Officer.
2. Complete an Incident Report Form (Annexure 1) with the following details:
   • Date, time, and location of the incident
   • Description of the hazardous material involved
   • Nature of the incident (spill, exposure, fire, etc.)
   • Names of affected personnel
   • Immediate actions taken
Escalation of Incidents:
• Supervisors must escalate serious incidents (e.g., injuries, fires) to the Safety Officer and senior management.
• Notify external authorities, such as fire departments or regulatory agencies, as required by law.

4.3 Incident Containment and Immediate Actions

1. Spill and Leak Response:
   1. Use spill kits to contain minor spills immediately while wearing appropriate PPE.
   2. Evacuate the area and contact emergency response teams for major spills.

2. Fire and Explosion Response:
   1. Activate fire alarms and use fire extinguishers (Class B) if trained to do so.
   2. Evacuate the area and notify emergency services immediately.
3. Exposure Response:
   1. Skin contact: Wash the affected area with water for at least 15 minutes.
   2. Eye exposure: Flush eyes using an eyewash station for 15 minutes.
   3. Inhalation: Move to fresh air and seek immediate medical assistance.
4. Documenting Actions:
   1. Supervisors must document all containment measures in the Incident Report Form (Annexure 1).

4.4 Incident Investigation

1. Initiating the Investigation:
   1. The Safety Officer must initiate the investigation within 24 hours of the incident.
   2. Assemble an incident investigation team, including the supervisor, operator(s), and Safety Officer.

2. Data Collection:
   • Interview witnesses and affected personnel to gather details about the incident.
   • Review relevant documents, including SDS, training records, and equipment maintenance logs.
   • Inspect the incident site for physical evidence, including leaks, damaged containers, or equipment.
3. Root Cause Analysis:
   1. Identify the root cause using techniques like the “5 Whys” method or fishbone diagrams.
   2. Classify contributing factors, such as:
      • Human error
      • Equipment failure
      • Process deviations
      • Insufficient training or inadequate PPE
4. Corrective and Preventive Actions:
   1. Recommend corrective actions to eliminate the root cause.
   2. Implement preventive measures, such as:
      • Updating SOPs
      • Providing additional training
      • Repairing or replacing faulty equipment

4.5 Reporting and Follow-Up

1. Submit the final Incident Investigation Report (Annexure 2) to senior management.
2. Verify the implementation of corrective and preventive actions through follow-up audits.
3. Maintain all incident-related records for a minimum of five years.
