Massachusetts Unrestricted Construction Supervisor License Practice Test

At what height does fall protection become necessary?

1. 4 feet

2. 6 feet

3. 8 feet

4. 10 feet

The correct answer is: 6 feet

Fall protection becomes necessary at a height of 6 feet when working in residential construction. This regulation is established by OSHA (Occupational Safety and Health Administration) to ensure the safety of workers who are at risk of falling while performing tasks at elevations. The rationale behind this specific height is tied to statistics surrounding fall-related injuries and fatalities, which underscore the importance of implementing preventive measures at relatively lower heights than in other types of construction, where fall protection requirements could vary. In general industry contexts, fall protection requirements may begin at different heights, but for residential work, 6 feet is the threshold that triggers the need for safety systems such as guardrails, safety nets, or personal fall arrest systems. Understanding this standard height is crucial for construction supervisors to maintain compliance with safety regulations and protect workers effectively.
