(a) "Efficient exhaust draught" means localised ventilation affected by mechanical or other

means for removal of dust or fume so as to prevent it from escaping into air of 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;

(e) "leadless glaze" means a glaze which does not contain more than one per cent of its dry

weight of a lead compound calculated as lead monoxide;"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 degrees centigrade and

thoroughly mixed shall be continuously shaken for one hour at the common temperature

with 1000 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) "potter's shop" includes all places where pottery is formed by pressing or by any other

processes and all places whereby pressing or by any other process and all places where

shaping, fettling or other treatment of pottery article prior to placing for the biscuit fire is

carried on; and

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;

(h) fettling of biscuit ware which has been fired in powdered flint or quartz except where this

is done in machine so enclosed as to effectively prevent the escape of dust;

(i) ware cleaning after the application of glaze by dipping or other process ;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
