Schedule III

Manufacture and Repair of Electric Accumulators

1. Savings.- This Schedule shall not apply to the manufacture or repair of electric

accumulators or parts thereof not containing lead or any compound of leads or to the repair

on the premises, of any accumulator forming part of a stationery battery.

2. Definitions.- For the purposes of this Schedule,-

(a) "Lead process" means the melting of lead or any material containing lead, casting,

pasting, lead burning, or any other work, including trimming, or any other

abrading or cutting of pasted plates involving the use, movement or manipulation

of, or contact with, any oxide of lead.

(b) "Manipulation of raw oxide of lead" means any lead process involving any

manipulation or movement of raw oxides of lead other than its conveyance in a

receptacle or by means of an implement from one operation to another.

3. Separation of certain processes.- Each of the following processes shall be carried on in

such a manner and under such conditions, as to secure effectual separation from one another,

and from any other process-

(a) Manipulation of raw oxide of lead;

(b) Pasting;

(c) Drying of pasted plates;

(d) Formation with lead burning ("tacking") necessarily carried on in connection

therewith; and

(e) Melting down of pasted plates.

4. Air space.- In every room in which a lead process is carried on, there shall be at least 14

cubic metres of air space, for each person employed therein, and in computing this air space,

no height over 3.5 metres shall be taken into account.

5. Ventilation.- Every work-room shall be provided with inlets and outlets of adequate size

as to secure and maintain efficient ventilation in all parts of the room.

6. Distance between workers in pasting room.- In every pasting room, the distance between

the center of the working position of any paster and that of the paster working nearest to him,

shall not be less than 1.5 metres.

7. Floor of work-rooms.- (1) The floor of every room in which a lead process is carried on

shall be,-

(a) of cement or similar material so as to be smooth and impervious to water:

(b) maintained in sound condition; and

(c) kept free from materials, plant, or other obstruction not required for, or produced

in, the process carried on in the room.

(2) In all such rooms other than grid casting shops, the floor shall be cleaned daily after being

thoroughly sprayed with water at a time when no other work is being carried on in the room.

(3) In grid casting shops, the floor shall be cleaned daily.

(4) Without prejudice to the requirements of sub-clause (1), (2) and (3) where manipulation

of raw oxide of lead or pasting is carried on, the floor shall also be,-

(a) kept constantly moist while work is being done;

(b) provided with suitable and adequate arrangements for drainage; and

(c) thoroughly washed daily by means of a hose pipe.

8. Work-benches. - The work-benches at which any lead process is carried on shall,-

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

(b) be kept free from all materials or plant not required for, or produced in, the

process carried on there at;

(c) all such work-benches other than those in grid casting shops shall 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;

(d) all such work-benches in grid ousting shops, shall be cleansed daily; and

(e) every work-bench used for pasting shall,-

(i) be covered throughout with sheet lead or other impervious material;

(ii) be provided with raised edges; and

(iii) be kept constantly moist while pasting is being carried on.

9. Exhaust draught.- The following processes shall not be carried on without the use of

an efficient exhaust draught,-

(a) Melting of lead or materials containing lead;

(b) Manipulation of raw oxide of lead, unless done in an enclosed apparatus so as to

prevent the escape of dust into the work-room;

(c) Pasting;

(d) Trimming, brushing, filing or any other abrading or cutting of pasted plates giving

rise to dust;

(e) Lead burning, other than,-

(i) 'tacking' in the formation room;

(ii) chemical burning for the making of lead lining for cell cases necessarily carried

on in such a manner that the application of efficient exhaust is impracticable.

Such exhaust draught shall be effected by mechanical means and shall operate on the dust or

fume given off as nearly as may be at its point of origin, so as to prevent it entering the air of

any room in which persons work.

10. Fumes and gases from melting pots.- The products of combustion produce in the

heating of any melting pot shall not be allowed to escape into a room in which persons work.

11. Container for dross.- A suitable receptacle with tightly fitting cover shall be provided

and used for dross as it is removed from every melting pot. Such receptacle shall be kept

covered while in the work-room, except when dross is being deposited therein.

12. Container for lead waste.- A suitable receptacle shall be provided in every work-room

in which old plates and waste material which may give rise to dust shall be deposited.

13. Racks and Shelves in drying room.- The racks or shelves provided in any drying room

shall not be more than 240 cms. from the floor not more than 60 cms in width. Provided that

‍495

as regards racks or shelves set or drawn from both sides the total width shall not exceed 120

cms. Such racks or shelves shall be cleaned only after being thoroughly damped unless an

efficient suction cleaning apparatus is used for this purpose.

14. Medical examination by Medical Officer.- Every worker employed in lead processes

shall be examined within 15 days of his first employment. Such examination shall include

tests for lead in urine and blood, ALA in urine, hemoglobin content, stippling of cells and

steadiness test.

15. Protective clothing.- Protective clothing shall be provided and maintained in good repair

for all persons employed in,-

(a) manipulation of raw oxide of lead;

(b) pasting; or

(c) the formation room;

and such clothing shall be worn by the persons concerned. The protective clothing shall

consist of a water-proof apron and water-proof footwear, and, also, as regards persons

employed in the manipulation of raw oxide of lead or in pasting, head coverings. The head

coverings shall be washed daily.
