When must personal fall arrest systems be used according to OSHA standards?

Personal fall arrest systems must be used when working more than 4 feet above the ground, as specified by OSHA standards. This regulation is in place to ensure the safety of workers engaged in activities that involve potential falls, such as construction or maintenance on elevated surfaces. The 4-foot threshold is particularly significant in general industry settings, which reflects the concern for safety given the risk of serious injuries or fatalities from falls at this height.

This requirement emphasizes the importance of using appropriate fall protection measures as soon as workers are exposed to the risk of falling, thereby aiming to prevent accidents and improve workplace safety overall. Understanding and adhering to these guidelines is crucial for every worker's safety when operating at elevated positions.
