(3) Prior to commencing work where there are potential RFR hazards, a competent person must assess potential RFR hazards of areas which may be accessed by employees in the course of their work, and post temporary signage to indicate areas where the RFR hazard exceeds the general population/uncontrolled MPE limits for exposure set forth in 47 C.F.R. 1.1310. Temporary signage must remain in place while work is performed and the hazard exists.
