Which statement is true about crawling in limited visibility?

• A. It is the fastest method to conduct a search.
• B. Firefighters should send out one person ahead of the team to recon the path.
• C. Firefighters should duck walk when they can not see the floor to increase search time.
• D. It allows firefighters to feel the floor in front of them with a tool.

Answer: (D)

In limited visibility, moving with a low, controlled posture that keeps you in contact with the floor helps you stay oriented and avoid hazards. Using a tool to feel the floor ahead gives tactile feedback about the surface—you can sense changes in texture, gaps, holes, debris, or steps before your feet or hands reach them. This proactive probing lets you confirm safe footing and anticipate obstacles, which is why this approach is the best option.

The other ideas don’t fit as well: rushing through a search isn’t safe, sending a single person ahead breaks team safety and accountability, and duck walking with no floor contact can be unstable and waste precious time.
