1. Citation
These regulations may be cited as the Factories and Industrial Undertakings (Dry Batteries) Regulations.

2. Interpretation
In these regulations, unless the context otherwise requires—
dolly-pressing room (電池心型壓室) means a room in which manganese dioxide is moulded and pressed to form black dollies for use in the manufacture of dry batteries;
dry batteries (乾電池) means dry-cell batteries containing manganese dioxide;
maintained (保持) means maintained in an efficient state, working order and good repair;
manganese dioxide (二氧化錳) includes any substance or combination of substances containing manganese dioxide;
mixing room (混調室) means a room in which manganese dioxide is mixed, ground or sifted for use in the manufacture of dry batteries.

3. Application
These regulations shall apply to every factory in which dry batteries are manufactured.

4. Storage
Manganese dioxide, ammonium chloride and carbon black shall be stored in a room which is not used for any other purpose.

5. Mixing rooms
Manganese dioxide shall be mixed, ground and sifted in a room which is not used for any other purpose.

6. Dolly-pressing rooms
Dollies shall be moulded and pressed in a room which is not used for any other purpose.

7. Dust
(1) Where dust containing manganese dioxide is likely to enter the atmosphere of any room at any stage during the process of manufacture of dry batteries, all practicable steps, including the siting of an exhaust ventilation as near as possible to the point of such entry, shall be taken to prevent the distribution of such dust throughout the atmosphere of such room. (71 of 1989 s. 13)
(2) The mixing, grinding and sifting of manganese dioxide shall be carried out within an air-tight mixer or other device which effectively prevents any dust containing manganese dioxide escaping therefrom.
(3) Containers used for the storage or in the conveyance of manganese dioxide shall be fitted with lids which effectively prevent dust containing manganese dioxide escaping therefrom.

8. Ventilation
Mechanical ventilation sufficient to provide at least 5 changes of air per hour shall be installed and maintained inside every mixing room and dolly-pressing room and shall be operated at all times when such room is in use.
