6. Assessment of potential noise exposure

(1)An employer or self-employed person shall—
(a)in respect of a workplace under his or her control cause an assessment to be done within six months after the commencement of these regulations and thereafter at intervals not exceeding two years, to determine if any person may be exposed to noise which is at or above the noise-rating limit, regardless of whether any personal hearing protectors are used; and
(b)cause the results of the assessments to be entered into the records as required by regulation 11.
(2)An employer contemplated in subregulation (1) shall, before causing an assessment to be made, consult with the relevant health and safety representative or the relevant health and safety committee and thereafter inform them in writing of the arrangements made for the assessment, allow them reasonable time to comment thereon and ensure that the results of the assessment are made available to them for comment.
(3)When making an assessment contemplated in subregulation (1), an employer or self-­employed person shall take into account and keep a record of relevant factors, including the following—
(a)The noise sources to which a person may be exposed;
(b)adverse health effects that the excessive noise may have on persons;

(ii)the type of work carried out; or
(iii)the type of equipment used to control exposure,
and subregulations (2) and (3) shall apply for such review assessment.

7. Noise monitoring

(1)Where an assessment of noise exposure or a review of such assessment indicates that any employee may be exposed to noise at or above the noise-rating limit, an employer contemplated in regulation 2 shall ensure that a measurement programme of noise exposure at that workplace is—
(a)carried out in accordance with the provisions of these regulations;
(b)carried out only after the relevant health and safety representative or relevant health and safety committee has been informed thereof and given a reasonable period, as mutually agreed upon, to comment thereon;
(c)carried out by an approved noise inspection authority; and
(d)representative of the employees’ exposure to noise, in accordance with subregulation (2).
(2)In order to comply with subregulation (1)(d), an employer shall ensure—
(a)that the measurement programme, in the case where a number of employees work in an area of approximately equal noise level, makes provision for the selection of not less than three locations which are representative of the positions occupied by employees well distributed over the area under investigation, and for the taking of measurements at each position as contemplated in SABS 083;
(b)that the measurement programme, in the case of an employee working at an approximately fixed location relative to the noise source, makes provision for the measurement to be taken at the approximate position of the person’s ear that receives the higher noise level as contemplated in SABS 083; and
(c)that representative measurements are carried out at least every 24 months: Provided that whenever the noise is at or above the noise-rating limit, the provisions of regulation 10(1) shall apply.
(3)An employer shall ensure that the results of measurements as contemplated in subregulation (2)(c) are recorded in the record required by regulation 11.

8. Medical surveillance

(1)An employer shall establish and maintain a system of medical surveillance for all employees exposed to noise at or above the noise-rating limit.
(2)An employer shall ensure that the medical surveillance contemplated in subregulation (1)—
(a)consists of a baseline audiogram which is recorded—
(i)in the case of a new employee, before the employee commences employment or within 30 days of commencement of such employment; or
(ii)in the case of all other employees in the employment of the employer, before 16 November 2003; and
(iii)in accordance with the requirements of Instruction No. 171:
Provided that the baseline audiogram conducted in terms of that instruction applies to that employee for the rest of his or her working career,
(b)consists of a periodic audiogram which is conducted in accordance with SABS 083 and which, during the first three years of employment, is obtained at least annually and thereafter at intervals which may be extended to a maximum period of two years if no referral threshold shift is evident: Provided that—
(i)employees working in, or required to enter, noise zones where the noise exposure equals or exceeds an 8-hour rating level of 105 dBA shall undergo audiometric testing at 6-monthly intervals until it is established that no referral threshold shift is evident and thereafter the interval between tests may be extended to a maximum interval of one year; and
(ii)employees who are regularly exposed to gunshots or other explosive events during their working day shall undergo audiometric tests at time intervals in accordance with subparagraph (i);
(c)consists of an exit audiogram, conducted in accordance with SABS 083, which is obtained for every employee whose employment is terminated or who is permanently transferred to another workplace in respect of which audiometric tests are not required: Provided that an audiogram conducted within six months prior to termination of employment or transfer shall meet this requirement; and
(d)is performed by a competent person: Provided that if it is impossible for the competent person to establish a baseline audiogram for an employee as contemplated in paragraph (a), the employee must be referred to an audiologist who may establish baseline-hearing levels by using other techniques, such as speech reception thresholds.
(3)An employer shall ensure that—
(a)copies of the audiograms contemplated in subparagraphs (2)(a), (b) and (c) are entered into the employee’s record of medical surveillance;
(b)a copy of each audiogram contemplated in subparagraphs (2)(a) and (c) is given to the employee when he or she leaves the employment of that employer;
(c)new employees provide him or her with their baseline audiograms, exit audiograms or most recent audiograms and the percentage of loss of hearing calculated in accordance with Instruction No. 171; and
(d)in the case of an employee whose percentage loss of hearing has deteriorated by 10% or more since the baseline audiogram was recorded or an employee for whom no baseline audiogram is available but who has a 10% or more loss of hearing that is not obviously due to medical causes, and that has been confirmed by a repeat audiogram—
(i)the relevant health and safety committee or the relevant health and safety representative is informed of the finding;
(ii)the employee is retrained and re-instructed as contemplated in regulations 4 and 5;
(iii)noise control measures are reassessed; and

(c)no person enters or remains in a noise zone unless he or she wears the required hearing protective equipment; and
(d)the reason why noise exposure is at or above the noise-rating limit is identified and that action is taken, as soon as is reasonably practicable, by means other than the use of hearing protective equipment, to lower the noise level so that it is not at or above the noise-rating limit.

10. Control of noise exposure

(1)An employer or self-employed person shall ensure that the exposure of a person to noise is either prevented or, where this is not reasonably practicable, adequately controlled: Provided that the control of the exposure shall be regarded as adequate if the exposure is below the noise-rating limit, or if the exposure is at or above the noise-rating limit but the reason has been identified and action is taken as soon as is reasonably practicable, by means other than the use of hearing protective equipment, to lower exposure so that it does not exceed the noise-rating limit.
(2)In order to comply with subregulation (1) an employer or self-employed person shall, as far as is reasonably practicable, reduce exposure to noise by implementing noise control measures in the following order of priority:
(a)Engineering control measures to eliminate or reduce noise at its source, or the modification of the routes by which noise reaches workplaces;
(b)administrative control measures to limit the number of persons exposed and the duration of exposure; and
(c)the use of hearing protective equipment if engineering and administrative control measures fail to reduce exposure below the noise-rating limit.

11. Record

An employer or self-employed person shall—
(a)keep records of the results of all assessments, noise monitoring and medical surveillance reports and of maintenance of control measures required by these regulations;
