Schedule V

Grinding or Glazing of Metals and Processes Incidental thereto

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

(a) "Grindstone" means a grindstone composed of natural or manufactured sandstone

but does not include a metal wheel or cylinder into which block of natural or

manufactured sandstone are fitted;

(b) "Abrasive wheel" means a wheel manufactured of bonded emery or similar

abrasive;

(c) "Grinding" means the abrasion, by aid of mechanical power, of metal, by means of

grindstone or abrasive wheel;

(d) "Glazing" means the abrading, polishing or finishing, by aid of mechanical power,

of metal, by means of any wheel, buff, mop or similar appliance to which any

abrading or polishing substance is attached or applied;

(e) "Racing" means the turning up, cutting or dressing of a revolving grindstone

before it is brought into use for the first time;

(f) "Hacking" means the chipping of the surface of a grindstone by a hack or similar

tool; and

(g) "Rodding" means the dressing of the surface of a revolving grindstone by the

application of a rod, bar or strip of metal to such surface.

2. Exceptions.- (1) Nothing in this Schedule shall apply to any factory in which only repairs

are carried on except any part thereof in which one or more persons are wholly or mainly

employed in the grinding or glazing of metals.

(2) Nothing in this Schedule except clause 4 shall apply to any grinding or glazing of metals

carried on intermittently and at which no person is employed for more than 12 hours in any

week.

(3) The Chief Inspector-cum-Facilitator may by certificate in writing, subject to such

conditions as he may specify therein, relax or suspend any of the provisions of this Schedule

in respect of any factory if owing to the special methods of work or otherwise such relaxation

or suspension is practicable without danger to the health or safety of the persons employed.

3. Equipment for removal of dust.- No racing, dry grinding or glazing shall be performed

without,-

(a) a hood or other appliance so constructed, arranged, placed and maintained as

substantially to intercept the dust thrown off;

(b) a duct of adequate size, air tight and so arranged as to be capable of carrying away

the dust, which duct shall be kept free from obstruction and shall be provided with

proper means of access for inspection and cleaning, and where practicable, with a

connection at the end remote from the fan to enable the Inspector-cum-Facilitator

to attach thereto any instrument necessary for ascertaining the pressure of air in

the said duct; and

(c) a fan or other efficient means of producing a draught sufficient to extract the dust:

Provided that the Chief Inspector-cum-Facilitator , may accept any other appliance

that is, in his opinion, as effectual for the interception, removal and disposal of dust thrown

off as a hood, duct and fan would be.

4. Restriction on employment on grinding operations.- Not more than one person shall at

any time perform the actual processes of grinding or glazing upon a grindstone, abrasive

wheel or glazing appliance:

Provided that this clause shall not prohibit the employment of persons to assist in the

manipulation of heavy or bulky articles at any such grindstone, abrasive wheel or glazing

appliance.

5. Glazing.- Glazing or other processes, except processes incidental to wet grinding upon a

grindstone shall not be carried on in any room in which wet grinding upon a grindstone is

done.

6. Hacking and rodding.- hacking or rodding shall not be done unless during the process

either,-

(a) an adequate supply of water is laid on at the upper surface of the grindstone; or

(b) adequate appliances for the interception of dust are provided in accordance with

the requirements of clause 3.

7. Examination of dust equipment.- (a) All equipment for the extraction or suppression of

dust shall at least once in every six months be examined and tested by a competent person,

and any defect disclosed by such examination and test shall be rectified as soon as

practicable.

(b) A register containing particulars of such examination and test shall be kept in a form

approved by the Chief Inspector-cum-Facilitator.

8. Medical Examination.- Every worker employed in grinding or glazing of metal processes

incidental thereto shall be examined within 15 days of his first employment. Such

examination shall include pulmonary function test and in suspected cases chest X-rays.
