What is defined as a containment system in hazardous materials management?

In hazardous materials management, a containment system is primarily designed to prevent the release of hazardous materials into the environment. This is vital for protecting human health, wildlife, and the surrounding ecosystem from potential exposure to harmful substances. Containment systems are integral in various situations, such as during the transport of hazardous materials, storage, or when dealing with spills.

Such systems can include physical structures like secondary containment basins, spill pallets, and liners that catch leaks or spills before they can escape into the environment. Properly designed containment systems can significantly mitigate the risk associated with handling hazardous materials, ensuring compliance with environmental regulations and promoting safety.

The other options focus on documentation, reporting procedures, and personal protective equipment, all of which are important aspects of hazardous materials management but do not directly relate to the containment of hazardous substances.
