Final answer:
The length of a dead-end corridor is typically regulated by fire safety codes. In buildings without sprinkler systems, the limit is usually 20 meters (65 feet). With a sprinkler system, it can be up to 45 meters (150 feet).
Step-by-step explanation:
The length of a dead-end corridor in a building is typically regulated by fire safety codes, but there is no specific limit set universally.
These codes usually require that the length of a dead-end corridor must not exceed 20 meters (65 feet) in buildings without sprinkler systems.
However, with a properly installed and maintained sprinkler system, the dead-end corridor can be longer, up to 45 meters (150 feet).
