Question

A barrier erected on a roof to warn employees that they are approaching an unprotected roof side or edge, and which designates an area in which roofing work may take place without the use of guardrail, body belt, or safety net systems to protect employees in the area is called:

Option 1. Warning line system
Option 2. Control line system
Option 3. Safety monitoring system
Option 4. Controlled access zone

Answer 1

The barrier described is called a warning line system; it designates a safe work area on construction sites to prevent fall hazards, in compliance with OSHA regulations.

Step-by-step explanation:

The barrier described in the question is known as a warning line system. This system is implemented on construction sites to create a designated safe work area by marking boundaries that employees can recognize as areas leading to potential fall hazards. OSHA regulations enforce employers to protect their workers by utilizing various methods such as fall protection systems, which include safety harnesses, guardrails, and the creation of controlled access zones to minimize the chances of accidents and injuries.

OSHA's standards mandate specific safety measures to be taken on construction sites, such as providing proper protective equipment — including safety helmets — and other critical safety protocols. Employers are also responsible under the General Duty Clause to maintain a workplace free of serious recognized hazards, even if no specific standard applies.
