REF: (a) PMS MIP 6241/002

(b) NSTM 600 Volume 2, Non Structural Closures, Section 11

Note: When installed at machinery space main accesses and at the top of escape trunks, the doors push open into passageways. When installed in console booths they push into the booth. When installed at the bottom of escape trunks, the doors push open into trunks. Doors should not obstruct continuous rung ladders when opening. Balanced design is defined as a door with an offset pivot at the door panel centerline. A pivot point near the center of the door panel balances forces exerted against the panel, preventing the door from slamming open during an explosion. Frequent inspection and thorough maintenance actions will ensure the proper operation of these doors.
