An employer must provide fall protection when workers are exposed to a fall of ________ ft. or above to a lower level.

The requirement for providing fall protection comes from OSHA regulations, which stipulate that fall protection must be provided for workers at elevations of 6 feet in the construction industry. This regulation ensures that adequate safety measures are in place to prevent falls that could result in serious injuries or fatalities. The threshold of 6 feet is recognized as a critical height where the risk of falling becomes significant enough to warrant the implementation of protective measures.

In construction environments, tasks that involve working at heights carry inherent dangers, and having a clear regulation helps employers and workers maintain safety standards. The importance of this regulation is rooted in the goal of safeguarding employees, ensuring that they have the necessary protections in place to mitigate hazard exposure when working from heights. Therefore, the correct answer is based on established safety protocols that prioritize worker welfare in hazardous conditions.
