What is one type of information in a pre-incident plan that should be instantly available?

• A. Water pressure data
• B. Hydrant locations
• C. Occupant names
• D. Building occupancy type

Answer: (B)

Having hydrant locations readily available in a pre-incident plan means the first-arriving crew can immediately identify where to obtain a water supply. Establishing an effective water source is one of the fastest, most critical steps in initial firefighting operations, so knowing which hydrants are nearby, how to access them, and the routes to reach them helps you deploy hose lines quickly and set up suppression efforts without delay. Other items like water pressure data, occupant names, or building occupancy type are useful for planning, but they do not provide an immediate, actionable starting point for securing water on arrival.
