Low-slope Roofs (Slope of 4: 12 or less)
For other low-slope roofs, employers may protect employees by either a guardrail system, safety net system, or personal fall arrest system (lanyards and body belts), or by the use of a warning line system in combination with a guardrail system, safety net system, personal fall arrest system or safety monitoring system. Employers need not hire an extra person to perform the task of safety monitor; one of the crew could be assigned this function. OSHA does require, however, that the monitor be able to see and communicate with the person(s) being monitored. Therefore, the monitor must not be given other duties that prevent him or her from fulfilling the monitoring function.
