How should the exhaust system of a bulk truck be installed?

• A. Horizontal behind the cab
• B. Extended vertically above the vehicle
• C. Wrapped in insulation
• D. Above the fuel tank

Answer: (B)

The best practice for installing the exhaust system of a bulk truck is to extend it vertically above the vehicle. This design allows for the proper dispersal of exhaust gases, minimizing the risk of those gases being drawn back into the vehicle or affecting the driver and crew. Vertical exhaust installation also helps in preventing the accumulation of harmful emissions and can reduce the likelihood of combustion or fire hazards, especially in environments where flammable materials may be present.

Additionally, positioning the exhaust system above the vehicle prevents potential damage from obstacles on the ground, such as debris or rough terrain, which could impede the safe operation of the truck. Proper exhaust routing is critical for the overall safety and functionality of the vehicle, especially in mining and hauling operations where heavy-duty vehicles must navigate challenging conditions.
