Terminology used in this manual is as generic as possible, just as it is in the standards of the National Fire Protection Association and the International Code Council. Many variations in terms will be encountered in different areas of the U.S. or in other countries. For example, this manual uses the term “aerial apparatus” to describe a fire service vehicle with a long, aerial ladder. Yet, in this country alone, other terms used to describe the same vehicle include: “truck,” “ladder,” “aerial,” “ladder truck,” “tower,” or “tower ladder.” Or, in some cases, the same terms could be used to describe a particular aerial fire apparatus. Similarly, in some areas the term “truck” refers only to aerial apparatus, while in other areas this term could also include pumper apparatus.

In another example of potentially confusing terminology, fire apparatus drivers in some areas of the country are referred to as “engineers.” Consider the situation of an architect speaking to a fire officer in an area where this terminology is used. You can easily see how the fire officer could use the term “engineer” to mean a driver, while the architect interprets the term as a building design engineer.
