Which term describes a portable ladder not fixed to a building?

• A. Ground ladder
• B. Bangor ladder
• C. Straight ladder
• D. Single ladder

Answer: (A)

Ground ladders refer to portable ladders that are carried to the scene and deployed from the ground rather than being attached to a building. They aren’t part of the structure; they’re moved and set up as needed and can be single-section or extension ladders. This makes the term the best fit for a ladder type that isn’t fixed to a building. The other names describe more specific ladder forms or older styles. A Bangor ladder is a historical heavy wooden ladder, not the general category for ladders used free on the ground. A straight ladder and a single ladder describe particular configurations of a ladder (non-extended or non-articulated) rather than the broad category of ladders that are portable and not fixed to any structure.
