What is the primary purpose of containment rules?

Answer: B — To protect people and the environment

The primary purpose of containment rules is to protect people and the environment. These regulations are designed to minimize the risk of hazardous materials escaping into the surroundings during transportation, storage, and handling. By enforcing containment measures, the goal is to prevent spills, leaks, and other potential hazards that could lead to exposure to harmful substances, thereby safeguarding public health and preserving ecological systems. Effective containment helps ensure that hazardous materials are managed responsibly, reducing the likelihood of accidents that could have far-reaching consequences for both people and the environment. The other options, while they may be relevant benefits or considerations in the broader context of hazardous material handling, do not capture the main focus of containment rules which centers on safety and environmental protection.
