What is the height to base width ratio requirement for supported scaffolds?

The height to base width ratio requirement for supported scaffolds specifies that when the ratio exceeds 4:1, the scaffold must be restrained from tipping. This guideline is significant because it addresses the stability of scaffolding structures. When the height of the scaffold is more than four times its base width, it becomes increasingly unstable and susceptible to tipping over.

This regulation is part of OSHA's efforts to prevent accidents and ensure worker safety on construction sites. By enforcing a limit on the height-to-base-width ratio, OSHA helps ensure that scaffolds are constructed and maintained in a way that minimizes the risk of falls or collapse, thereby protecting the workers who rely on these structures for safe access to higher work areas.
