What is defined as a steep grade when driving an ARFF apparatus?

A steep grade, especially in the context of driving an Aircraft Rescue and Fire Fighting (ARFF) apparatus, is typically defined as a 30° angle. This degree of incline poses significant challenges for vehicle handling, stability, and traction—factors that are crucial during emergency responses.

At a 30° incline, operators must be mindful of how the steepness can affect braking performance, acceleration, and the overall control of the apparatus. It can also impact the distribution of weight within the vehicle, which is vital when carrying firefighting equipment and personnel. Understanding the dynamics of driving on steep grades allows ARFF personnel to make informed decisions and maneuver effectively during emergencies, ensuring safety and efficiency in critical situations.
