Most of this information is taken from Essential Safety Measures Maintenance Manual 4th edition, Government of Victoria, Australia Means of Egress actually covers all of the following and should be checked on a quarterly basis. Paths of travel to Exits Internal paths of travel in a building that provide an unobstructed pathway for occupants travelling to an exit. It is the responsibility of the owner to ensure that all paths of travel to exits are maintained in an efficient condition and kept functional and clear of obstruction at all times. Discharge from Exits External paths and discharge points that provide an unobstructed pathway for occupants travelling to a road or open space. Exits Fire-isolated passageways, ramps and stairs are to provide occupants with safe egress from a building. Exits include fire-isolated stairways and ramps, non-fire isolated stairways and ramps, stair treads, balustrades and handrails associated with exits, and fire-isolated passageways. At the entrance point to these elements, fire doors are provided. Fire doors are to be of a specified fire-resistance level, that are either self-closing or have automatic closing facilities linked to smoke or heat detectors or to a fire alarm or sprinkler system installed in the building. Smoke lobbies to Fire-isolated exits Smoke lobbies to fire-isolated exits are to provide occupants with safe egress from a building and prevent smoke from entering a stair……and are fitted with smoke doors that are either self-closing or have automatic closing facilities linked to smoke or heat detectors, or to a fire alarm or sprinkler system installed in the building. The smoke lobby may also be pressured if the required exit stair is required to be pressurised under the smoke hazard management provisions. Open access ramps or balconies for fire-isolated exits Open access ramps and balconies are to provide occupants with safe egress from a building. Doors These are doors that are other than fire or smoke doors in a required exit, forming part of a required exit or in a path of travel to a required exit, and associated self-closing, automatic closing and latching mechanisms that provide sufficient and safe egress from a building, with a minimum of effort and delay, and to present a minimum of obstruction in an exit path. It could be fitted with a fail-safe device that unlocks the door automatically when any sprinkler, smoke or heat detector system is activated in the building. An exit door must be capable of simple operation to fulfil its designed purpose. An exit door may be a swinging door or could be a sliding door. Sliding doors may be manually operated or power operated.
