Which of the following is a physical method to manage hazardous spills?

Covering is recognized as a physical method to manage hazardous spills because it involves placing a barrier over the spilled material. This barrier can help contain the spread of the hazardous substance, minimizing the risk of exposure to the environment and individuals nearby. By physically covering the spill, responders can prevent further contamination and allow for safer cleanup procedures to be implemented.

In contrast, dilution refers to the process of adding a large volume of water or another substance to reduce concentration but may not physically contain the spill. Detoxification and neutralization involve chemical processes that alter the composition of the hazardous material rather than employ a physical method to manage the spill.
