At a minimum, firefighters must work in teams of _____ when entering an involved structure.

• A. two
• B. three
• C. seven
• D. five

Answer: (A)

Entering an involved structure is extremely hazardous—heat, smoke, poor visibility, and the risk of collapse demand that firefighters have a partner to rely on. The minimum team size ensures a buddy system is in place so one firefighter can monitor conditions, perform tasks, and be ready to withdraw or assist the other if danger escalates. This setup also supports clear communication, accountability, and rapid rescue if something goes wrong, such as running out of air or needing a quick exit. While larger teams are used for more complex tasks like searching, ventilation, or back-up, the basic safety requirement for interior entry is two people working together.
