Are standpipes required in underground buildings due to the ease of advancing hose lines down stairwells?

Standpipes in underground buildings are generally not required due to the ease of advancing hose lines down stairwells. The rationale behind this is that firefighters can effectively use stairwells to transport hoses and tackle fires without the need for additional standpipe systems in such structures. The layout and accessibility of underground buildings can often mitigate the need for standpipes as a principal means of fire suppression.

Moreover, modern building codes and standards often account for the unique challenges of underground construction, leading to decisions that prioritize firefighter access and the ability to safely maneuver equipment. In many cases, the design of the building itself allows for adequate fire protection measures without necessitating standpipe installation.

This perspective aligns with current fire safety regulations, which are evaluated and updated to ensure effective firefighting tactics and equipment can be employed as needed.
