5 Scaffold Erection L & M Masonry Fall Protection SUBPARTSMasonry Fall Protection3Scaffold ErectionThe employer shall have a competent person determine the feasibility and safety of providing fall protection for employees erecting or dismantling supported scaffolds. A Competent Person is "one who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them."
6 L & MSUBPARTSMasonry Fall Protection4Scaffold ErectionThe employer shall have each employee who is involved in erecting, disassembling, moving, operating, repairing or maintaining a scaffold trained by a competent person to recognize any hazards associated with the work in question.

13 Scaffold Erection L & M Masonry Fall Protection SUBPARTSMasonry Fall Protection11Scaffold ErectionThe employer shall have a competent person determine the feasibility and safety of providing fall protection for employees erecting or dismantling supported scaffolds. Employers are required to provide fall protection for employees erecting or dismantling supported scaffolds where the installation and use of such protection is feasible and does not create a greater hazard. The employer must be able to explain and support a decision that it creates a greater hazard. Even if the competent person determines that being tied off during erection is not feasible, a harness/lanyard must still be worn by the workers.Photo depicts hazardous condition
