At what floor height does OSHA require protection for open sides?

The Occupational Safety and Health Administration (OSHA) mandates that guardrails or equivalent protection must be provided for open sides of platforms, floors, and runways that are 4 feet or more above the next lower level. This regulation is in place to help prevent falls, which can lead to serious injuries or fatalities in the workplace.

By requiring protection at this height, OSHA aims to enhance safety standards, ensuring that workers are less exposed to the risks associated with working at elevated levels. The 4-foot threshold is a standard recognized in various safety guidelines, reflecting best practices in fall prevention.
