These storage systems will maintain EPA and OSHA compliance with easy-access tote and pallet storage for materials needing secondary spill containment and security. Our Non Fire-Rated storage can contain materials that can be stored without fire-rated containment, while still providing simple material handling with forklift for bulk storage in your workflow processes.
