Schedule IV

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 atmosphere inconditions

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) "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 com- pound exceeding when

calculated as lead monoxide, 5 percent 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 100oC

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 theclear filtrate shall then be

precipitated as lead sulphide and weighed as leadsulphate.

2. Exhaust draught

The following processes shall not be carried -on except under an

efficient exhaust draught or under 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 ammonical vapors

are given off.

(d) All processes in the making of furnace moulds or "pots" including the

grinding or crushing of used "pots"

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

(f) All furnaces, heating ovens and driers.

(g) All machineries involving the secondary processing on glass material

3. Floors and work-benches

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

The floor shall be--

(a) Of cement or similar material so as to be smooth and impervious to

water;

(b) Maintained in sound conditions;and

(c) cleaned daily after being thoroughly sprayed with water at a time when

no other work is being carried on in the room.

The work-benches shall—

(a) have as mooth surface and be maintained in sound condition,and

(b) be 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 there at.

4. 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 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.

5. Storage and transport of Hydrofluoric acid

Hydrofluoric acid shall not be stored or transported except in cylinders or

receptacles made of lead or rubber.

6. Suitable facilities shall be readily available for sterilizing the blow-pipes used

by the glass blowers and such blow-pipes shall be sterilized at the beginning of

the operations of blowing, each day.

7. Work near furnaces

i. No person shall carry out any work near furnace within the distance

dangerous to the health and safety.

ii. All precautions shall be taken to prevent de-hydration to the workers

employed near-by.

8. Provision of safety arrangements

i) Suitable interlock arrangement shall be provided and maintained in all

the machines so as to ensure the safety of persons employed therein.

ii) No process or work shall be carried on in such a manner as to cause

risk of bodily injury to the persons employed.

9. Food, drinks, etc., prohibited in workrooms

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.

10. 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 persons concerned.

11. Washing facilities

There shall be provided and maintained in a cleanly state and in good

repair for the use of all persons employed in the processes specified in

paragraph 3

(a) A washplace 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 61 centimeters

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 61 centimeters ; or

ii. at least one wash basin for every five such persons employed at any one

time, fitted with a waste pipe and plug and having an adequate supply of

water laid on or always readily available; and a sufficient supply of clean

towels made of suitable materials renewed daily with a sufficient supply

of soap or other suitable cleansing material and of nail brushes;and

(b) a sufficient number of stand pipes with taps - the number and location

of such stand pipes shall be to the satisfaction of the Chief Inspector-cum-

Facilitator.

12. Medical facilities and record of examinations and tests

(1) The Occupier of every factory in which glass manufacturing processes are

carried out, shall

(a) Employ a Health Surveillance Officer for medical surveillance of the

workers employed therein.

(b) Provide to the said Health Surveillance Officer all the necessary

facilities for the purpose referred to in clause (a); and

(2) Workers employed in this scheduled process/operation shall be medically

examined by the Health Surveillance Officer-

i. Once before employment,to ascertain the physical fitness of the person

to do the particular job:

ii. Once in a period of six months, to ascertain the health status of all the

workers in respect of occupational health hazards to which they are

(2) may be employed again in the same process only after obtaining the

Fitness Certificate from the Medical Officer and after making entries to that
