Containment berms are barriers designed to prevent the spread of liquids, such as oil or chemicals, in case of spills or leaks. They are typically made from materials like earth, sand, or synthetic materials and are used in various settings, including industrial sites and construction areas. The primary purpose of a containment berm is to protect the environment and surrounding areas from contamination. These berms can be temporary or permanent structures, depending on the specific needs of a site. They are often used in conjunction with other safety measures, such as spill kits and drainage systems, to ensure effective management of hazardous materials and to comply with environmental regulations.
