To prevent the pollution of water and soil, a secondary line of defense—in addition to the primary container or vessel—is often required when containing chemicals, fuel, oil or other hazardous liquids. Secondary spill containment equipment like drum containment pallets, spill containment trays and kits can all be used to prevent leakage into the exterior environment should a breach in the first container occur. In addition to overall environmental protection, secondary protection measures also ensure worker safety in busy, potentially hazardous worksites, warehouses, plants and industrial facilities. Determine the approximate capacity you’ll be protecting for before procuring your secondary spill containment equipment and accessories.
