(a)  “manganese process” means processing, manufacture or manipulations of manganese or any ore or any mixture  containing  manganese;


(b)  “Manipulations” means mixing, blending, filling, emptying, grinding, sieving, drying, packing,  sweeping, or otherwise  handling of  manganese, or mixture  containing manganese; and


(c)  “efficient exhaust ventilation” means localised ventilation effected by mechanical means for the removal of dust or fume or at its source of origin so as to prevent it  from  escaping  into  the  atmosphere of any place where any work  is  carried on.  No draught shall be deemed to be efficient which fails to remove the  dust or fume or mist at the point where it  is generated  and  fails to prevent it  from escaping into and  spreading into the atmosphere of a work place.


3.                   Isolation of a process -  Every manganese process which  may  give rise to dust, vapour or mist containing manganese, shall be carried on in a totally enclosed system or otherwise effectively  isolated from  other processes so that other plants and processes and  other parts of the factory and persons employed on other processes may not be affected by the same.


4.                   Ventilation  of process -  No process in which  any dust, vapour or  mist  containing  manganese  is generated, shall be carried out except under an efficient exhaust ventilation which shall be applied as near to the point of generation as practicable.
