Final answer:
The statement is true. Guardrail systems are required on ramps and runways when there is an unprotected side or edge to prevent falls and protect against hazards, aligning with safety regulations often mandated by OSHA.
Step-by-step explanation:
The statement that a guardrail system used on a ramp or a runway needs to be erected on each unprotected side or edge is true. Guardrails serve as protective barriers that help prevent falls and other accidents by providing a physical barrier on areas where there is a drop-off, such as ramps and runways. They are critical safety features in construction and general industry to protect both workers and the public from potential hazards.
In the context of Occupational Safety and Health Administration (OSHA) regulations, guardrails are typically required when there is a risk of falling from an elevated area. For ramps and runways used in the workplace, having guardrails is an essential safety requirement if there is a drop of 6 feet or more to lower levels. Additionally, even if the drop is less than 6 feet, a guardrail may still be necessary if there is a risk of falling onto dangerous equipment or hazards.
