4.40 .         Charging of aerosol and disposable containers

        (1)         In this regulation "charging" means the action of filling aerosol containers or disposable containers with unodorised LPG.

        (2)         A person shall not in a building, cause or permit any aerosol containers or disposable containers to be charged with unodorised LPG — 

            (a)         without the prior approval of the Chief Inspector; and

            (b)         unless the building and facilities used for that purpose conform with these regulations.

        (3)         The LPG charging area in a building shall be separated from all other parts of the building by a wall which may have the following but no other openings — 

            (a)         a doorway; and

            (b)         openings each not exceeding 0.1 m ² in area for the passage of containers into and from the charging area.

        (4)         A charging area shall be equipped with a system of mechanical ventilation that is separate from any other such system in the building, and so constructed, maintained and operated that — 

            (a)         the atmosphere in the charging area is kept less than 25% of the lower explosive limit for the gas; and

            (b)         escaping gas does not flow through any doorway or other opening referred to in subregulation (3).

        (5)         The ducting of the system of mechanical ventilation shall not pass through any part of the building other than the charging area and shall be such that the air drawn from the charging area is discharged into the atmosphere outside the building at a point above every part of the roof of the building that is within 10 m, measured laterally, from that point.

        (6)         The door of a doorway referred to in subregulation (3) shall — 

            (a)         have double hinges so as to be capable of being opened both inwards and outwards; and

            (b)         be kept closed at all times except when opened for the passage of persons or materials.

        (7)         All pipes carrying LPG from the storage tank to the charging area shall — 

            (a)         conform to Australian Standard CB 18 being item 8 in Schedule 2, or be approved;

            (b)         be joined by welding;

            (c)         be equipped with a manual shut-off valve at the tank and manual shut-off valve immediately outside the building; and

            (d)         be equipped with an excess flow valve and a manual shut-off valve at every point where the gas enters a flexible connection to the charging machine.

        (8)         The valves referred to in subregulation (7)(c) and (d) shall conform to AS 1596 being item 7 in Schedule 2.

        (9)         A gas detector which will function whenever LPG is present in the air at any concentration of 25% or more of the lower explosive limit for the gas shall be installed in a position adjacent to every charging machine and every opening referred to in subregulation (3)(b).

        (10)         For the purpose of subregulation (9) a gas detector is regarded as functioning only if it — 

            (a)         produces a continuous sound of not less than 105 decibels;

            (b)         gives a continuous visible signal; and

            (c)         shuts off the flow of gas into the building referred to in subregulation (3).

        (11)         Power operated machines used within the charging area shall comply with requirements of AS 2359 being item 9 in Schedule 2.
