Section 59

In every factory in which, in connection with any process carried on, there is given off any dust or fume or other impurity of such a character and to such extent as to be likely to be injurious or offensive to the persons employed, or any substantial quantity of dust of any kind, all practicable measures shall be taken to protect the persons employed against inhalation of the dust or fume or other impurity and to prevent its accumulating in any workplace, and in particular, where the nature of the process makes it practicable, exhaust appliances shall be provided and maintained, as near as possible to the point of origin of the dust or fume or other impurity, so as to prevent it entering the air of any workplace.

No stationary internal combustion engine shall be used unless provision is made for conducting the exhaust gases from the engine into the open air.

The atmosphere of any workplace in which dangerous or obnoxious substances are manufactured, handled or used shall be tested by a competent person at sufficient intervals to ensure that toxic or irritating dusts, fumes, gases, fibres, mist or vapours are not present in quantities liable to injure health of persons employed.

A record of the result of every test carried out under subsection (3) shall be kept available for inspection by an inspector for at least 3 years from the date of the test.

The occupier of a factory shall place warning notices in places where there are special risks to which the persons employed are exposed and the precautions to be taken to obviate such risks.

The requirements of subsections (1) and (3) shall not apply to any workplace where it is impracticable to comply with such requirements and where breathing apparatus is used by a person working thereat.

The Minister may by order published in the Gazette specify the permissible levels of toxic substances in the workplace of a factory.[54
