Which department should be contacted in case of a hazardous material spill?

The correct choice indicates contacting the Department of Aviation in the event of a hazardous material spill. This department typically oversees safety protocols and regulatory compliance at airports, making it essential to report such incidents to an authority that can coordinate an immediate and effective response.

In aviation contexts, the Department of Aviation is often responsible for ensuring that any safety issues or emergencies are managed according to strict guidelines. They have the resources and training needed to respond to hazardous spills safely, protecting airport operations and ensuring the safety of passengers, staff, and the surrounding area.

While other departments may deal with related issues—such as environmental protection or transportation safety—the Department of Aviation is specifically equipped to handle incidents that occur in the airport environment, where quick action is necessary to mitigate risks associated with hazardous materials.
