Practices:

1. Use proper equipment (e.g., trolleys with spill containment) for moving chemicals.
2. Secure containers to prevent tipping or jostling during transport.

Inspection and Maintenance:

1. Conduct weekly inspections of chemical storage areas for leaks, damaged containers, or improper labeling.
2. Maintain spill kits in designated locations and ensure they are fully stocked with absorbents, neutralizers, and PPE.

4.2 Spill Response and Management

4.2.1 Classification of Spills

Spills are classified based on their size and severity:

• Small Spill: Less than 500 ml, easily manageable by trained personnel.
• Medium Spill: Between 500 ml and 5 liters, requiring assistance from the safety team.
• Large Spill: Over 5 liters or involving highly toxic, flammable, or reactive substances requiring full emergency response.

4.2.2 Spill Response Steps

1. Immediate Actions:
   1. Stop the source of the spill, if it is safe to do so.
   2. Evacuate the area and restrict access to unauthorized personnel.
   3. Alert nearby employees and the safety officer immediately.

2. Assess the Spill:
   1. Determine the size, location, and hazard type of the spill using the SDS.
   2. Identify the need for respiratory protection and ventilation for airborne chemical spills.
3. Spill Containment and Clean-Up:
   1. For small spills:
      • Wear proper PPE (gloves, goggles, respirators, suits).
      • Use absorbent pads, spill pillows, or vermiculite to contain and clean the spill.
      • Neutralize acids or bases using suitable neutralizing agents.
   2. For medium spills:
      • Follow the steps for small spills, but request assistance from the safety team.
      • Place contaminated absorbents in labeled hazardous waste containers.
   3. For large spills:
      • Activate the emergency response plan and evacuate personnel to a safe distance.
      • Contact emergency responders (fire department, hazmat teams).
      • Shut down HVAC systems to prevent chemical vapors from spreading.
4. Post-Cleanup Procedures:
   1. Dispose of all used absorbents, PPE, and contaminated materials as hazardous waste.
   2. Decontaminate tools, equipment, and the spill area using suitable cleaning agents.
   3. Restock the spill kit immediately after use.

4.3 Reporting and Documentation

1. Document all spill incidents in the Chemical Spill Report Log (Annexure 1), including:
   • Date and time of the spill
   • Location
   • Type and quantity of chemical
   • Personnel involved
   • Actions taken
2. Submit the spill report to the Safety Officer within 24 hours for review and corrective actions.
3. Investigate the root cause of significant spills and implement preventive measures.

4.4 Spill Response Training

1. Conduct annual training sessions on spill prevention, response protocols, and proper use of spill kits.
2. Include mock spill drills for small, medium, and large spills to ensure preparedness.
3. Maintain training records and ensure all personnel are updated on current procedures.
