Why is it important to segregate incompatible hazardous materials during transport?

Segregating incompatible hazardous materials during transport is crucial primarily to prevent dangerous reactions that can result in fires or explosions. When certain materials come into contact with each other, they can react chemically in ways that create extreme hazards. For example, mixing oxidizers with flammable substances can lead to combustion, while acids might react violently with certain bases, producing gases or heat that can be hazardous to both the driver and the public. Ensuring that these substances are stored separately minimizes the risk of such dangerous interactions, thereby enhancing safety during transportation.

The other choices do touch on important aspects of transporting hazardous materials, such as compliance and potential cost savings, but they do not directly address the critical safety issues that arise from mixing incompatible materials. Safety is always the primary concern when transporting hazardous goods, making the prevention of dangerous reactions the most important reason for segregation.
