SOP for Maintenance of Hazardous Material Storage Cabinets

Standard Operating Procedure for Maintenance of Hazardous Material Storage Cabinets

1) Purpose

The purpose of this SOP is to ensure that hazardous material storage cabinets are maintained in good condition to safely store hazardous chemicals, prevent spills, leaks, or contamination, and comply with safety regulations.

2) Scope

This SOP applies to all hazardous material storage cabinets in laboratories, warehouses, and production facilities where chemicals, flammable substances, and other hazardous materials are stored.

3) Responsibilities

  • Operators: Perform routine checks and ensure cabinets are used as per guidelines.
  • Maintenance Personnel: Conduct periodic maintenance, repair, and replacement of storage cabinets.
  • Supervisors: Verify maintenance schedules and documentation are followed.
