Tas Part H117 Premises for lead processing

Tas H117.1 Application of Part

This Part is applicable to every building in which lead processes are used.

Premises for lead processing must—


provide for the safety and comfort of workers; and


be constructed in a manner that will minimise the lodgement of dust and must be capable of being flushed with water.

Tas H117.2 Floors


The floor of every work place where a lead process is used must be—


so constructed of concrete or other suitable material as to be smooth and impervious to fluids; and


graded and properly drained to permit flushing with water.


The material of which the floor is constructed must be applied to the walls to a height of not less than 75 mm in such a fashion that the angle between the walls and the floor is coved for easy cleaning.

Tas H117.3 Height of lead processing areas

Every part of a lead processing area must be not less than 2.7 m in height—


where a ceiling is provided, measured from the floor to the ceiling; or


where a ceiling is not provided, measured from the floor to the lowest part of the roof.

Tas H117.4 Air space and floor space


In every lead processing area there must be not less than 14 m3 of air space for each person employed therein, and in the calculation of such space the maximum height taken must be not greater than 4.2 m; and


total floor space for the persons employed in such area, exclusive of space used for storage, must be not less than 3.3 m2 for each person so employed.

Tas H117.5 Interior of lead processing areas


The inner surfaces of the walls of every lead processing area must be of a smooth material impervious to fluids and must not contain any projections on which dust may lodge; and


the interior construction of the ceiling or roof must, so far as is practicable, be such that dust will not settle on it.

Tas H117.6 Dust collection

Any areas in which dust-forming lead materials are manipulated, moved or treated must be served by a mechanical exhaust ventilation system capable of safely and effectively collecting all dust.

Tas H117.7 Isolation of certain processes

Where any process of pasting of electric accumulator plates or drying of paste plates, or melting down of pasted plates or of formation with tacking in the electric accumulator industry or of manipulation of dry oxide of lead, is to be carried on in the same room as any other lead process, the processes of pasting, drying, melting, formation or manipulation must be isolated from one another and from any other lead process—


by a partition extending from the floor to the ceiling in the case of a room having a ceiling not more than 3.6 m in height, or to a height of 2.7 m in any other case; or


by some other suitable method.

Tas H117.8 Drying room shelves

The racks or shelves provided in any drying room must not be more than 2.6 m from the floor nor more than 650 mm in width except that, in the case of racks or shelves set or drawn from both sides, the total width must not exceed 1.3 m.

Tas H117.9 Washing facilities

Washing facilities served with running hot and cold water for the use of all employees engaged in a lead process must be provided consisting of—


one washbasin for each 5 employees, or part thereof; and


one shower bath for each 8 employees, or part thereof.

Tas H117.10 Change rooms

In every work place in which lead is processed there must be provided two suitable furnished change rooms for the use of employees as follows—


one of the change rooms must be used for taking off, storing, and putting on of the street clothing of employees; and


the other of the change rooms must be used for the taking off, storing, and putting on of overalls and other clothing worn in any work room; and


each change room must be so constructed and situated as to prevent the entry into the room of dust or fumes generated in a workroom; and


each change room must be in close proximity to the washing facilities required in Tas H117.9.
