When you respond to an extensive number of calls, apparatus breakdowns are bound to occur. With technology advancing in the fire apparatus industry, components are becoming more expensive to replace and/or repair. Sometimes we need to reflect and see what is really needed, especially when vehicle wear and tear is constant.
I remember the supervision books I read when studying for promotional exams always seemed to have a statement to the effect of, "You can always judge how well a department is run when the manager is not present."
Having worked in the fire service for more than 30 years, I completely agree with this idea. The training and competency of your personnel is showcased in times when a manager is not around.
