1. Potential blowout

2. Road hazard

3. Fire risk

4. All of the above

The correct answer is: All of the above

When an overheated tire is discovered on a hazardous materials vehicle, the primary concern encompasses multiple risks that can arise due to the condition of the tire. An overheated tire is at a significant risk of experiencing a blowout, which can result in the driver losing control of the vehicle, particularly dangerous when transporting hazardous materials. This loss of control could lead to spills or accidents that pose serious risks to both the driver and the surrounding environment. In addition to the risk of a blowout, an overheated tire presents a fire hazard. The high temperatures can cause the materials within the tire to ignite, especially if there are flammable chemicals being transported. A fire can rapidly escalate, endangering life and property, while also creating further complications in dealing with hazardous materials. Lastly, an overheated tire contributes to road hazards. If the tire fails while the vehicle is in motion, it can create dangerous conditions for other drivers and pedestrians. Detritus from a blown tire can litter the roadway, posing additional risks. Taking all these factors into account, the concern with an overheated tire on a hazardous materials vehicle is indeed multi-faceted, touching on potential blowouts, road hazards, and fire risks.
