Which of the following falls under fall protection regulations?

The selection related to construction work at height is correct because fall protection regulations specifically target situations where employees are at risk of falling from elevated surfaces. These regulations are put in place to ensure the safety of workers performing tasks such as installation, maintenance, or construction activities that occur above ground level, generally defined as six feet or more.

In these environments, the potential for serious injuries or fatalities from falls is significant, prompting strict compliance requirements that may include the use of guardrails, safety nets, personal fall arrest systems, and training focused on recognizing and mitigating fall hazards.

In contrast, the other scenarios mentioned—working on the ground level, data entry jobs, and office work without hazards—do not fall under these regulations as they typically involve no significant risk of falling from heights. Therefore, they are governed by different safety standards that address other workplace hazards.
