Which of the following is an example of information typically included in a pre-incident plan?

• A. Hydrant locations
• B. Occupant contact numbers
• C. Fire truck maintenance history
• D. Alarm system codes

Answer: (A)

Understanding what information supports quick, safe fire suppression before firefighters arrive is key. Pre-incident planning focuses on site characteristics that directly affect on-scene actions, especially water supply and access routes.

Hydrant locations are included because they identify where water can be drawn to attack the fire, help plan the initial water supply strategy, and inform decisions about hose lay, the number of lines needed, and apparatus placement. Knowing hydrant locations on a site map lets responders quickly connect to a reliable water source and anticipate any potential delays or obstructions, which is critical for an effective early attack.

Other items miss that primary focus. Occupant contact numbers might be helpful in some situations, but they’re not central to immediate firefighting actions and can raise privacy concerns. Fire truck maintenance history belongs to equipment management, not the incident action plan. Alarm system codes are security-sensitive information and not routinely included in pre-incident planning.

So hydrant locations best fit the purpose of guiding rapid, effective water supply during an incident.
