7. Noise

(1)Subject to the provisions of subregulations (2) and (3), no employer shall require or permit an employee to work in an environment in which he is exposed to an equivalent noise level equal to or exceeding 85 dB (A).

(2)Where the equivalent noise level to which employees are exposed in any workplace is equal to or exceeds 85 dB (A), the employer shall reduce the level to below 85 dB (A) or, where this is not practicable, he shall reduce the level to as low as is practicable and take all reasonable steps to isolate the source of the noise acoustically: Provided that where the equivalent noise level to which employees are exposed is such that the attenuation of the hearing protectors to be provided in terms of subregulation (6) does not reduce the said noise level to below 85 dB (A), the employer concerned shall limit the time during which employees work in that noise zone in such way that they are not exposed to an equivalent noise level of more than or equal to 85 dB (A).

(3)Where the equivalent noise level in any workplace cannot practicably be reduced to below 85 dB (A), the employer in such workplace shall—

(a)demarcate the boundaries of all noise zones in such workplace by posting up notices to that effect in conspicuous places along such boundaries and at all exits from and entrances to any room where the whole of such room constitutes a noise zone; and

(b)prohibit any person from entering a noise zone unless such person wears hearing protectors.

(4)In the case of building work where it is impracticable to comply with the provisions of subregulation (3) (a) owing to the nature or extent of the premises, the employer shall post up such notices at all exits from and entrances to such premises or, where this is not possible or practicable, display such notices in a conspicuous place as close as possible to the actual workplace or in such place as an inspector may direct.

(5)Whenever an inspector is of the opinion that an employer has omitted or failed to reduce the noise level in a noise zone to as low as is practicable or to isolate the source of die noise acoustically, ne may require such employer, by notice in writing, to take such further steps as such inspector considers reasonable and practicable for the purpose of conserving the hearing of employees entering or working in such noise zone.

(6)Every employer shall provide, free of charge, hearing protectors to each employee who works in or to any person who is required or permitted to enter a noise zone, and no employer shall require or permit any person to work in or enter such noise zone, and no person snail work in or enter such noise zone unless he wears such hearing protectors in the correct manner.

(7)The hearing protectors which an employer shall provide in terms of subregulation (6) shall be—

(a)for the sole use of that person: Provided that if an inspector is satisfied that the employer has taken adequate precautionary measures to ensure that the common use of hearing protectors will not result in the spreading of infectious or contagious diseases, he may, in writing, authorise the common use of hearing protectors;

(b)maintained by the employer in an efficient and hygienic condition at ail times; and

(c)stored in a clean, dust-free container provided by the employer when not in use.

(8)An employer shall properly instruct any employee who is required to wear hearing protectors in the use of such protectors and inform him of the noise zones where the wearing thereof is compulsory.
