 Well, my dear students, the course is Labour Policy Pakistan and the topic is section 14, 15 and 16 of the factories act 1934. Section 14 deals with disposal of waste and affluence. Subsection 1, effective arrangements shall be made in every factory for the disposal of waste and affluence due to the manufacturing process carried on therein. Therein is better than therein in the factory. It has been discussed with you earlier that therein, therefore, there to, where in, where of, where to, where by, thens forth, in sub-terminologies, to open dictionaries or to understand. Section 14, subsection 2, the provincial government may make rules prescribing the arrangements to be made under subsection 1 or requiring that the arrangements made in accordance with that subsection shall be subject to the approval of such authority as may be prescribed. Section 15 or heading a ventilation and temperature effective and suitable provisions shall be made in every factory for securing and maintaining in every workroom, adequate ventilation by the circulation of fresh air and such temperature as will secure to workers therein, therein samradha in the factory, reasonable conditions of comfort and prevent injury to health and in particular the walls and roofs shall be of such material and so designed that such temperature shall not be exceeded but kept as low as practicable. Dear students, where the nature of work carried on in the factory involves or is likely to involve the production of excessively high temperature, such adequate buyers as are practicable shall be taken to protect the workers therefrom by separating the process which produces such temperature from the workroom by insulating the hot parts or by other effective means. The provincial government may prescribe a standard of adequate ventilation and reasonable temperature for any factory or class or description of factories or parts thereof and direct that a thermometer shall be provided and maintained in such place and position as may be prescribed. So, what is the meaning of the word reasonable? The word reasonable demands that such conditions and such conditions are suited to the circumstances. For example, the temperature in the winters will differ in the factory and the temperature in the summers will differ. So, the word reasonable will change its meaning and standard according to the weather. Section 16, my dear students, are heading a dust and fume in every factory in which by reason of the manufacturing process carried on, there is given of any dust or fume or other impurity of such a nature and to such an extent as is likely to be injurious or offensive as is likely to be injurious or offensive or offensive to the workers employed therein, therein, thereof, thereby, whereby, wherein, whereof, henceforth, henceforth. Effective measures shall be taken to prevent its accumulation in any work room and its inhalation by workers and if any exhaust appliances 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. Hope you have understood this very topic. Thank you very much.
