What is an important practice for operators to be familiar with regarding the apparatus?

Familiarity with driving the apparatus is crucial for operators because it directly impacts safety and efficiency during emergency responses. Mastery of the driving skills allows operators to navigate various environments, handle the vehicle under different conditions, and ensure a swift response when every second counts. As an operator, understanding the vehicle's dimensions, handling characteristics, and how it performs under stress is vital to avoid accidents and ensure safe operations.

While knowing about maintenance schedules, the historical context of the apparatus, and controls are important, they do not influence immediate operational capabilities in the same way that driving proficiency does. The primary responsibility during emergencies is to operate the vehicle effectively to reach the incident location swiftly and safely, whereby any additional knowledge becomes secondary in urgent situations.
