Scissor stairways typically have standpipes on which type of floors?

• A. Adjacent floors
• B. Alternating floors
• C. Consecutive floors
• D. Single floors

Answer: (B)

Scissor stairways are a design feature often utilized in buildings to provide two separate paths for egress and improve safety during emergencies. The presence of standpipes in scissor stairways is essential because they provide necessary access to water for firefighting efforts. The standpipes are typically positioned on alternating floors to ensure accessibility for firefighters while minimizing obstruction in the stairway egress routes. This configuration allows firefighters to quickly connect hoses to the standpipes and reach different levels without having to navigate through a heavily congested area. Choosing standpipes on alternating floors also facilitates a more efficient response during an emergency by distributing fire resources effectively throughout the stairway system. This way, if one section is compromised or blocked, firefighters can still access standpipes on different levels, maintaining operational capability.
