Abstract: A system and method for a scaffold deck with a fall arrest assembly is disclosed. The fall arrest assembly comprises a deck structure (102) and a rail assembly (122) for permitting an individual to tie-off in a manner that permits the individual with a range of motion along the deck structure. The fall arrest assembly further includes an uplift hook mechanism (120) connected to or otherwise installed on the deck structure such that the uplift hook mechanism is employed for both securing the deck structure to and releasing the deck structure from at least one supporting member. A plurality of deck hooks (118) connectable to or otherwise installed on the decking structure for connecting the decking structure to the supporting member is additionally provided. A deck latch assembly located connected to the uplift hook mechanism additionally facilitates connection of the deck structure to a second deck structure.
