Mini-storage refers to premises providing separate self storage cubicles to individuals for storing household goods or to small business for storing inventory or archived records.
Mini-storages should comply with the fire safety requirements stipulated under the FS Code. The common contraventions of the FS Code found in mini-storages are:
- Excessive travel distance in the exit routes due to extensive partitioning of the storage cubicles.
- Inadequate width of exit routes along aisles between the storage cubicles due to swing-out cubicle doors.
- Obstruction to the exit routes by exit doors with unsuitable locking devices (i.e. could not be readily opened from inside without the use of a key).
- Replacement of fire rated doors by doors with inadequate fire resisting rating.
The aisles between the storage cubicles form part of the exit route and their clear width should not be less than that required under Table B2 of the FS Code (i.e. at least 1050mm wide, excluding the swing path(1) of any doors). Having regard to the mode of operation of mini-storages and the fire risk, the following arrangements are considered acceptable:
- For storage cubicles with usable floor area of not more than 5m2 and self-closing cubicle doors, the minimum clear width between the swing path of the cubicle doors and the walls or swing path of the doors on the opposite side of the aisle is 750mm.
- For storage cubicles with usable floor area of not greater than 1.5m2 and self-closing cubicle doors that can be opened flat against adjoining walls/cubicles and do not obstruct the swing path of the doors on the opposite side of the aisle, the door swing can be disregarded in measuring the clear width of the aisle.
The general requirements for mini-storages are:
- The maximum deadend travel distance between the furthest point on the premises to a point where an alternative exit is available is 18m.
- The maximum travel distance to the nearest protected exit (including deadend travel distance) is 36m.
- The maximum length of the exit route between an escape staircase and any one of the other escape staircases is 48m.
