Schedule B VI

Manufacture and treatment of lead and certain compounds of lead

1. Definitions.For this purpose of this schedule

a. "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. In the case of paints and similar products and other

mixtures containing oil or fat the "dry weight" means the dry

weight of the material remaining after the substance has been

thoroughly mixed and treated with suitable solvents to remove

oil, fats, varnish or other media.

The method of treatment shall be as follows:-

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 1,000 times its weight of an aqueous solution of hydrochloric acid

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 precipitate as lead sulphate and weighed as lead sulphate;

b. "Efficient exhaust draught" means localised 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,

fume, or dusts originate.

2. Application.- This schedule shall apply to all factories or parts of factories

in which any of the following operations are carried on:-

b.

work at a furnace where the reduction or treatment of zinc or lead ores is

carried on;

the manipulation,treatment or reduction of ashes containing lead, the

desilvering of lead or the melting of scrap lead or zinc;

d.

the manufacture of solder or alloys containing more than ten per cent of lead;

the manufacture of any oxide, carbonate, sulphate, chromate, acetate, nitrate

or silicate of lead;

f. the handling or mixing of lead tetra-ethyl;

9.

оn.

any other operation involving the use of a lead compound; and

h. The cleaning of workrooms where any of the operations aforesaid are carried

3. Prohibition 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 paragraph1.

4. Requirements to be observed.—No person shall be employed or permitted

to work in any process involving the use of lead compounds if the process is

such that dust or fume from a lead compound is produced therein, or the

persons employedtherein are liable tobe splashed with any lead compound

in the course of their employment unless the provisions of paragraphs 5 to 13

are complied with.

5. Exhaust draught.—Where dust, fume, gas or vapour is produced in the

process, provision shall be made for removing them by means of an efficient

exhaust draught to contrive as to operate on the dust, fume, gas or vapour as

closely as possible to the point of origin.

6. Medical facilities and record of examinations and tests.-

I. The occupier of every factory in which grinding or glazing of metals are

carried out, shall-

a.

employ a qualified medical practitioner for medical surveillance of the

workers employed therein whose appointment shall be subject to the

approval of the Chief Inspector-cum-Facilitator; and

Provide to the said medical practitioner all the necessary facilities for

the purpose referred to in clause (a).

I1. The record of medical examinations and appropriate tests carried out by the

said medical practitioner shall be maintained in a separate register approved

by the Chief Inspector-cum- Facilitator, which shall be kept readily available

for inspection by the Inspector-cum-Facilitator.

7. Medical examination by the Medical Officer.-

I.

every worker employed shall be examined by a Medical Officer within 15 days

of his first employment. Such examination shall include pulmonary function

tests and in suspected cases chest X-rays. No worker shall be allowed to work

after 15 days of his first employment in the factory unlesscertified fit for such

employment by the Medical Officer.

II.

Every worker employed in the said processes shall be re-examined by a

Medical Officer at least once in every 3 calendar months. Such re-examination

shall, wherever the Medical Officer considers appropriate, include tests as

specified in sub-paragraph (I).

III.

The Medical Officer after examining a worker, shall issue a Certificate of

Fitness in Form XXIII. The record of examination and re-examinations carried

out shall be entered in the Certificate and the Certificate shall be kept in the

custody of the manager of the factory. The record of each examination carried

out under subparagraphs (I) and (II), including the nature and the results of

the tests, shall also be entered by the Medical Officer in a health register in

Form XXIV.

IV.

The Certificate of Fitness and the health register shall be kept readily available

for inspection by the Inspector- cum-Facilitator.

V. If at any time the Medical Officer is of the opinion that a worker is no longer

fit for employment in the said processes on the ground that continuance

therein would involve special danger to the health of the worker he shall

make record of his findings in the said certificate and the health register. The

entry of his findings in those documents should also include the period for

which he considers that the said person is unfit for work in the said

processes. The person so suspended from the process shall be provided with

alternate placement facilities unless he is fully incapacitated in the opinion of

the Medical Officer, in which case the person affected shall be suitably

rehabilitated.

VI.

No person who has been found unfit to work as said in sub-paragraph (5)

shall be re-employed or permitted to work in the said processes unless the

Medical Officer, after further examination, again certifies him fit for

employment in those processes.

8. Food, drinks, etc. prohibited in workroom.- No food, drink, pan and
