Facilities working with hazardous chemicals often keep spill containment supplies readily available to contain contents and ensure safe cleanup. These spill control supplies range from reusable bags designed to capture dirt and debris at construction sites to aggressive, universal spill kits with a 10-gallon capacity. Spill containment equipment such as hydra barriers and sandbags work to hold back flood waters and limit the spread of spilled liquids. Specialized handheld kits such as portable oil cleanup kits help clean up oil spills up to 6 gallons.
