69. A health and safety committee is established upon a written notice sent to the employer by a certified association or, if there is no certified association, by at least ten per cent of the workers or, in the case of an establishment employing fewer than forty workers, by at least four of these, or upon such a notice sent by the employer to a certified association or, if there is no certified association, to the workers as a whole. A copy of the notice must be sent to the Commission.
The Commission, where it considers it expedient, may require the establishment of a health and safety committee, regardless of the number of workers in the establishment.
