When used on a suspended scaffold, attach the PFAS to a vertical or horizontal lifeline or to a structural member.
As with any type of PPE, harnesses and lanyards must be a last resort for fall protection. It must first be determined if the fall hazard can be eliminated by removing the need to work at heights or near the unprotected hazard. If this is infeasible, what engineering controls can be put in place? For example, can you install guard rails, cover the opening, block or restrict access to unprotected areas, use a scissors lift instead of a ladder, or install a personal fall restraint system? If none of these are feasible, or are used and additional fall protection is necessary, then personal fall arrest systems must be used. All workers should receive training by a competent person on how to correctly use a PFAS, as well as the fall hazards they will face. Those who have never worn or used a full-body harness before—or have not received training in how to use one correctly—are at risk, given that improper use can lead to a serious injury.
OSHA requires employers to provide for fall protection according the list mentioned above. All hazards are to be addressed using the hierarchy of controls.
