What is the minimum free passage width required on a stairway when installing chairlifts?

The minimum free passage width required on a stairway when installing chairlifts is 20 inches. This specification is important to ensure that the chairlift can operate safely without obstructing movement on the stairs. A wider passage allows for enough room for the chairlift's operation and the safe passage of individuals using the stairway.

When chairlifts are installed, it is essential to meet building codes and safety standards that dictate these dimensions to prevent accidents and ensure that the chairlift is accessible to all users, particularly individuals with mobility challenges. The 20-inch width is considered a standard that balances safety with functionality, ensuring that users can navigate alongside the chairlift without risk of injury.

While other widths suggested might seem adequate at a glance, they fall short of the necessary clearance that ensures both safety and compliance with regulations surrounding the installation of such devices in public or private stairways.
