Question

12 multiple choice 1 point you are retrofitting a public library to comply with accessibility standards. what does the law require for stair design? bp 220 requires closed risers and rounded treads for visual safety in all stairs above two levels. the fire code allows one handrail if stair width does not exceed 1.20 meters. bp 344 requires dual handrails, non - slip finishes, and consistent riser/tread dimensions within set limits. nbcp mandates handrails on open stairs and permits varied riser dimensions for adaptive reuse.

Explanation:

Building codes often have specific requirements for stair - design in public buildings to ensure accessibility and safety. BP 344 is a common code that mandates dual handrails, non - slip finishes, and consistent riser/tread dimensions within set limits for accessibility compliance. The other options have inaccuracies such as BP 220's statement about all stairs above two levels (not a general accurate statement), the Fire Code's one - handrail condition may not be the main accessibility - related requirement here, and NBCP's allowance of varied riser dimensions goes against accessibility standards which require consistency.

Answer:

C. BP 344 requires dual handrails, non - slip finishes, and consistent riser/tread dimensions within set limits.
