At what height above a scaffold platform are guardrails or personal fall arrest systems required by OSHA?

5 ft
10 ft
15 ft
20 ft

The correct answer is: 10 ft

Guardrails or personal fall arrest systems are required by OSHA at a height of 10 feet above a scaffold platform to ensure worker safety. This regulation is in place because falls are one of the most common causes of workplace injuries and fatalities in construction. By implementing guardrails or personal fall arrest systems at this height, workers are provided with a means of protection against the risk of falling from elevated surfaces. The 10-foot requirement is established to balance safety precautions with the operational needs of construction sites, where workers frequently operate at significant heights. Adhering to this regulation helps create a safer working environment and reduces the likelihood of accidents that can lead to serious injuries or death.
