What is a bollard used for in firefighting infrastructure?

• A. A device that ensures only one direction flow.
• B. A type of sprinkler head.
• C. Freestanding post designed to protect fire hydrants.
• D. A support for a ladder rung.

Answer: (C)

A bollard is a freestanding post placed around critical firefighting infrastructure, like fire hydrants, to shield them from vehicle collisions and keep access clear. By absorbing or deflecting impacts, bollards prevent damage to hydrants and ensure firefighters can quickly connect hoses and deploy water during an emergency. They’re sturdy, anchored to the ground, and commonly used in areas with high vehicle traffic or tight maneuvering space to maintain a safe, unobstructed path to the hydrant.

The other options don’t fit because a bollard is not a device that controls flow, not a sprinkler head, and not a support for a ladder rung.
