Schedule XIV

POTTERY

1. Definitions

For the purposes of this schedule

(a) 'Pottery' includes earthenware, stoneware, porcelain, China tiles and any

other articles made from clay or from a mixture containing clay, any other

materials such as quartz, flint, feldspar and gypsum.

(b) 'efficient exhaust draught' means localized ventilation affected by

mechanical or other means, for the removal of dust or fume so as to

prevent it from escaping into the air or any place in which work is carried

on. No draught shall be deemed efficient which fails to remove effectively

dust or fume generated at the point where dust or fume originates;

(c) 'fettling’ includes scalloping, towing, sand papering, sand sticking, brushing

or any other process of cleaning of pottery-ware n which dust is given off ;

(d) ‘leadless glaze' means a glaze which does not contain more than one

percent of its dry weight of a lead compound calculated as lead monoxide;

(e) 'Low solubility glaze' means a glaze which does not yield to dilute

hydrochloric acid more than five per cent. of its dry weight of a soluble

lead compound calculated as lead monoxide when determined in the

manner described below: —

A weighed quantity of the material which has been dried at 100°C and

thoroughly mixed shall be continuously shaken for one hour at the

common temperature with 1,003 times its weight of an aqueous solution of

hydrochloric acid containing 0.25 per cent. by weight of hydrogen chloride.

This solution shall thereafter be allowed to stand for one hour and then

filtered. The lead salt contained in the clear filtrate shall then be

precipitated as lead sulphide and weighed as lead sulphate;

(f) 'ground or powdered flint or quartz' does not include natural sands;

(g) 'potter's shop' includes all places where pottery is firmed by pressing or

by any other process and all places where shaping, fettling or other

treatment of pottery articles prior to placing for the biscuit rue is carried

on.

2. Efficient exhaust draught

The following processes shall not be carried on without the use of an

efficient exhaust draught:

(i) All processes involving the manipulation or use of a dry and unfitted lead

compound;

(ii) The fettling operations of any kind, whether on green ware or biscuit,

provided that this shall not apply to the wet fettling, and to the

occasional finishing of pottery articles without the aid of mechanical

power;

(iii) The sifting of clay dust or any other material for making tiles or other

articles by pressure, except where

(a) this is done in a machine so enclosed as to effectively prevent the

escape of dust ; or

(b) the material to be shifted is so damp that no dust can be given off;

(iv) The pressing of tiles from clay dust, an exhaust opening being connected

with each press ; this clause shall also apply to the pressing from clay

dust of articles other than tiles, unless the material is so damp that no

dust is given off ;

(v) The fettling of tiles made from clay dust, by pressure. except where the

fettling is done wholly on, or with, damp material;

(vi) The fettling of other articles made from clay dust, unless the material is

so damp that no dust is given off;

(vii) The process of loading and unloading of saggars, where handling and

manipulation of ground and powdered flint, quart, alumina or other

materials are involved ;

(viii) The brushing of earthenware biscuit, unless the process is carried on in

a room provided with efficient general mechanical ventilation or other

ventilation which is certified by the Inspector-cum-Facilitator as

adequate, having regard to all the circumstances of the case ;

(ix) Fettling of biscuit ware which has been fired in powdered flint or quartz

except where this is done in machines so enclosed as to effectively

prevent the escape of dust;

(x) Ware cleaning after the application of glaze by dipping or other

process;

(xi) Crushing and dry grinding of materials for pottery bodies and saggars,

unless carried on in machines so enclosed as to effectively prevent the

escape of dust or is so damp that no dust can be given off ;

(xii) Sieving or manipulation of powdered flint, quartz,daygrog or mixture of

these materials unless it is so damp that no dust can be given off ;

(xiii) Grinding of tiles on a power- driven wheel unless an efficient water

spray is used on the wheel ;

(xiv) Lifting and conveying of materials by elevators and conveyors unless

they are effectively enclosed and so arranged as to prevent escape of

dust into the air in or near any place in which persons are employed;

(xv) The preparation or weighing out of flow material,tawning of dry colors,

colour dusting and colour blowing;

(xvi) Mould making, unless the bins or similar receptacles are used for

holding plaster of paris and provided with suitable covers;

(xvii) The manipulation of calcined materials unless the material has been

made and remain so wet that no dust is given off.

3. Certain processes to be carried on so as to secure effective separation

from one another

Each of the following processes shall be carried on in such a manner and

under such conditions so as to secure effectual separation from one

another, and from wet processes:

(a) Crushing and by grinding or sieving of materials, fettling, pressing of

tiles, drying day and green ware, loading and unloading of saggars

;and

(b) All processes involving the use of a dry lead compound.

6. Prevention of dust

(1) All practical measures shall be taken by damping or otherwise to prevent
