Glass Manufacture
1. Definitions– For the purpose of this Schedule-
a) “Efficient exhaust draught” means localized ventilation, effected by mechanical means for the
removal of gas, vapour, dust or fumes so as to prevent them (as far as practicable under the
atmospheric conditions usually prevailing) from escaping into the air of any place in which work
is carried on. No draught shall be deemed efficient, which fails to remove smoke generated at the
point where such gas, vapour, fumes, or dusts originate.
b) “Lead compound” means any compound of lead other than galena which, when treated in
themanner described below, yields to an aqueous solution of hydrochloric acid aquantity of
soluble lead compound exceeding, when calculated as lead monoxide, five percent of the dry
weight of the portion taken for analysis.
The method of treatment shall be as follows:
A weighted quantity of the materials which has been dried at 100-degree C. and thoroughly
mixed shall be continuously shaken for one hour, at the common temperature with 1,000 times
its weight of an aqueous solution of hydrochloric acid containing 0.25 percent 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.
2. Exhaust draught – Thefollowing process shall not be carried on except under an efficient exhaust
draught or such other conditions as may be approved by the Chief Inspector-cum- Facilitator:-
a) The mixing of raw materials to form a “ batch”;
b) The dry grinding, glazing and polishing of glass or any article of glass;
c) All processes in which hydrofluoric acid fumes or ammoniacal vapours are given off;
d) All processes in the making of furnace moulds or “pots” including the grinding or crushing of
used “pots”; and
e) All processes involving the use of dry lead compound.
3. Prohibitions relating to women and young persons – No pregnant women or young person shall be
employed or permitted to work in any of the operations specified in paragraph 2 or at any place where
such operations are carried on.
4. Floors andwork benches – The floor and work-benches of everyroom in which a dry compound of lead
is manipulated or in which any process is carried on giving off silica dust shall be kept moist and shall
comply with the following requirements.-
a) The floors shall be –
i. of cement or similar materials so as to be smooth and impervious to water;
ii. maintained in sound condition; and
iii. cleansed daily after being thoroughly sprayed with water at a time when no other work is
being carried on in the room; and
b) the work benches shall-
i. has smooth surface and be maintained sound condition; and
ii. cleansed daily either after being thoroughly damped or by means of a suction cleaning
apparatus at a time when no other work is being carried on thereat.
5. Use of hydrofluoric acid – The following provisions shall apply to rooms in which glass is treated with
hydrofluoric acid:-
a) There shall be inlets and outlets of adequate size so as to secure and maintain efficient ventilation
in all parts of the room;
b) The floor shall be covered with gutta-percha and be tight and shall slope gently down to a covered
drain;
c) The work-placeshall beso enclosed in projecting hoods that openings required for bringing in the
objects to be treated shall be as small as practicable; and
d) The efficient exhaust draught shall be so contrived that the gases are exhausted downwards
6. Storage and transport of hydrofluoric acid. – Hydrofluoric acid shall not be stored or transported
except in cylinders or receptacles made of lead or rubber.
7. Blow pipes. – Every glass blower shall be providing with a separate blow pipe bearing the distinguishing
mark of the person to whom it is issued and suitable facilities shall be readily available to every glass
blower for sterilizing his blowpipe.
8. Food, drink, etc., prohibited in work-rooms. – No food, drink, pan and supari or tobacco shall be

paragraph 2 is carried on.
9. Protective clothing- The occupier shall provide, maintain in good repair and keep in a clean condition

sufficient length to allow of at least 60 cm for every five such persons employed at any one
time, and having a constant supply of water from taps or jets above the trough at intervals of
not more than 60 cm.; or
ii. at least one wash basin for every five such persons employed at any one time, fitted with
