Schedule ‘H’(iv)

GLASS MANUFACTURE AND PROCESS INCIDENTAL THERETO

1. Exemption.—If the Chief Inspector-cum -Facilitator is satisfied in respect of any factory or any

class of process that, owing to the special methods of work or the special conditions in a

factory or otherwise, any of the requirements of this schedule can be suspended or relaxed

without danger to the persons employed therein, or that the application of this schedule or any

part thereof is for any reason impracticable, he may by a certificate in writing authorised such

suspension or relaxation as may be indicated in the certificate for such period and on such

conditions as he may think fit.

2. Definitions—For the purposes of this schedule—

(a) "Efficient exhaust draught'' means localised ventilation affected 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, fume, or dust

originate.

(b) "First Employment" means first employment in the Process specified in paragraph 3 and

on glass blowing and shall also include re-employment in such Process following any

cessation of employment for a continuous period exceeding three calendar months, and

"Lead compound''' means any compound of lead other than galena, which, when treated

in the manner described below, yields to an aqueous solution of hydrochloric acid a

quantity of soluble lead compound exceeding, when calculated as lead monoxide, five

per cent of the dry weight of the portion taken for analysis.

The method of treatment shall be as follows :

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 1,000

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.

3. Exhaust draught.—The following recesses shall not be carried on except under an efficient

exhaust draught or under such other conditions as may be approved by the Chief Inspector :

(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 hydrochloric acid fumes or ammonical vapours are given off;

(d) all processes in the making of furnace mould or "pots" including the grinding or crushing

of used "pots"; and

(e) all processes involving the use of a dry lead compound; and

(f) any other operation which omits dust , vapour or gas or mist or smoke or soot while

further processing the glass bangles or other glass products by joining, grinding,

decorating, annealing, remitting, painting, printing, abrasive blasting, etching, marking

etc.

4. Prohibition relating to women and young persons.—No women or young person shall be

employed or permitted to work in any of the operations specified in paragraph 3 and on glass

blowing or at any place where such operations are carried on.

5. Floors and workbenches.—The floor and work-benches of every room 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 material so as to be smooth and impervious to water;

(ii) maintained in sound conditions; and

(iii) cleansed daily after being thoroughly sprayed with water at a time when no other

work is being carried on in the room.

(b) The work-benches shall—

(i) have a smooth surface and be maintained in sound condition, and

(ii) be cleansed daily either after being thoroughly dampened or by means of a

suction cleaning apparatus at a time when no other work is being carried on

thereat.

6. 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 places shall be so enclosed in projecting hoods teat 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.

7. Storage and transport of Hydrofluoric Acid.—Hydrofluoric acid shall not be stored or

transported except in cylinders or receptacles made of lead or rubber.

8. Food, drinks, etc. prohibited in workroom.—No food, drink, pan and supari or tobacco shall be

brought into or consumed by any worker in any room or work place wherein any process

specified in paragraph 3 is carried on.

9. Protective clothing.—The occupier shall provide, maintain in good repair and keep in a clean

condition for the use of all persons employed in the processes specified in paragraph 3,

suitable protective clothing, footwear and goggles according to the nature of the work and such

clothing, footwear, etc. shall be worn by the concerned persons.

10. Washing facilities.—There shall be provided and maintained in cleanly state and in good repair

for the use of all persons employed in the processes specified in paragraph 3 :

(a) a wash place with either—

(i) a trough with a smooth impervious surface fitted with a waste pipe, without plug,

and of sufficient length to allow of at least two feet 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 2 feet; or

(ii) at least one wash basin for every five such persons employed at any one time,
