Abstract A flip door assembly 406 includes a flip door 408 and an interlock 410 that controls whether the flip door 408 may be opened. A worker safety system 401 in one embodiment includes a work stand 402, a safety barrier 418, and a flip door assembly 406. The flip door assembly 406 selectively engages with a keyed portion 416 of the safety barrier 418 to prevent access to a defined area 504 by a worker. The flip door assembly 406 includes a flip door 408 having a top surface 422 that is substantially planar to a top surface of the work stand when closed, and substantially non-planar to the top surface of the work stand when open. The flip door assembly 406 further includes an interlock 410 that prevents the flip door from opening when the keyed portion 416 of the safety barrier 418 is disengaged from the interlock, and allows the flip door 408 to open when the keyed portion 416 of the safety barrier 418 is engaged with the interlock 410. rr00 (0 ( I co 00 I =a ~- C(- L0 -----------------I oo/
