When using a safety monitoring system, the system can only be utilized on roofs that are how wide maximum?

The correct answer reflects the guidelines for safety monitoring systems as they pertain to roof widths during construction or maintenance activities. A safety monitoring system is designed to ensure worker safety when performing tasks at heights, particularly in roofing scenarios where fall hazards are present.

Under OSHA (Occupational Safety and Health Administration) regulations, a safety monitoring system can only be employed on roofs that are no wider than 50 feet. This limitation is in place because the broader the area covered, the more difficult it becomes for a monitor to effectively oversee all workers and manage risks associated with falls. The 50-foot limitation ensures that adequate supervision can be maintained, reducing the likelihood of accidents and ensuring that employees working at heights are properly protected.

When working on wider roofs, alternative methods, such as guardrails or personal fall arrest systems, are required to provide proper safety measures for those involved. This approach promotes a comprehensive focus on safety by adapting to the specific conditions and risk factors presented in different roofing scenarios.
