Storage requirements depend on the type and quantity of hazardous materials.

  • Keep current inventory and SDSs on site and available to responders.
  • Provide secondary containment and spill controls for liquids where required.
  • Schedule regular inspections and staff training; document dates and outcomes.
Proper labeling and secondary containment prevent most common storage incidents.
