S.L. 646.3 Art. 18Testing ofairinthe working environment.

(1) It shall be the duty of the employer to make arrangements when so considered necessary by the Sanitary

Authority and to the satisfaction of the said Authority, so that the atmosphere of work-rooms in which potentially dangerous or obnoxious substances are manufactured, handled or used, is tested periodically.

(2) Such tests are to be carried out at sufficiently frequent intervals to ensure that toxic or irritating dusts, fumes, gases, fibres, mists or vapours are not present in quantities which, in the opinion of the Sanitary Authority, are liable to injure health, and to ensure that an atmosphere which is fit for respiration is maintained.

(3) Work in, or entry into any place where there is reason to suspect that the atmosphere is toxic, poisonous, asphyxiating or otherwise dangerous to health, shall not be carried out until the atmosphere is suitably tested and found free from any danger to health.

(4) The employer shall likewise ensure periodical testing of the working environment where a potential hazard exists for heat, noise and other physical agents.

(5) All tests referred to in this regulation shall be conducted by trained personnel and, where possible, supervised by qualified personnel who possess experience in occupational health or hygiene.
