Factories Act, 1948
14. Dust and fume
(1) In every factory in which, by reason of the manufacturing
process carried on, there is given off any dust or fume or other impurity of
such a nature and to such an extent as is likely to be injurious or offensive to
the workers employed therein, or any dust in substantial quantities, effective
measures shall be taken to prevent its inhalation and accumulation in any
workroom, and if any exhaust appliance is necessary for this purpose, it shall
be applied as near as possible to the point of origin of the dust, fume or
other impurity, and such point shall be enclosed so far as possible.
(2) In any factory no stationary internal combustion engine
shall be operated unless the exhaust is conducted into the open air, and no
other internal combustion engine shall be operated in any room unless effective
measures have been taken to prevent such accumulation of fumes there from as
are likely to be injurious to workers employed in the room.
