What safety equipment is required for all vehicles operating on airport property?

The correct answer is focused on the critical safety equipment that ensures both compliance with regulations and the safety of personnel and passengers in the high-traffic airport environment. Fire extinguishers are essential for quickly addressing any unexpected fires that may arise from accidents or vehicle malfunctions. Reflective triangles serve as a warning mechanism to alert other vehicles to a potential hazard, thereby enhancing safety on the often-busy airport roadways.

In the context of airport operations, where the risk of vehicle accidents or emergencies can be higher due to the presence of aircraft and the need for prompt response, having both a fire extinguisher and reflective triangles is pivotal. These items meet both safety and regulatory requirements specific to the operational standards set forth for vehicles on airport property.

The other options, while they may contain useful equipment, do not encompass the specific combination of items deemed necessary for ensuring safety in a high-risk area like an airport. For instance, while first aid kits and spare tires are certainly helpful, they do not directly address immediate fire hazards or traffic-related visual warnings as effectively as the fire extinguisher and reflective triangles do.
