Joaquin is a carpenter who, with his team, provides a range of services to both commercial and residential clients. A local restaurant has hired him to build a deck overlooking a gorge. The first step is to mark the footings with strings and pour the concrete piers that will provide the footing. After that, the team will install the girders and the floor joists. As the deck will be built on a slope leading down into the gorge, will Joaquin need to provide a fall protection plan for his team? 1. Yes, because conventional fall protection equipment is impossible to use in this situation. 2.Yes, because, once the flooring of the deck is in place, there will be leading and unprotected edges. 3.No, because personal fall arrest systems (PFAS) can be attached to the surrounding trees for safety. 4.No, because this is commercial construction.
