What is the limitation for free fall when using frontal D-rings?

The limitation for free fall when using frontal D-rings is set at 2 feet, making this the correct answer. This regulation is in place to minimize the potential for injury due to sudden deceleration and the forces experienced by the body during a fall. Frontal D-rings are typically used in harness systems designed for fall protection, and they provide a secure point of attachment for personal fall arrest systems.

A critical aspect of fall protection is to avoid excessive free fall distance, which can occur if a worker falls a significant distance before the fall protection system engages. By limiting the free fall distance to 2 feet, the system ensures that the impact forces on the body are within acceptable limits, reducing the chance of serious injury.

While other options suggest different limitations, they do not align with standard guidelines for the use of frontal D-rings in fall protection scenarios, where safety measures are designed to mitigate the risks associated with falls effectively.
