A critical analysis of the current South African occupational health law and hearing loss.

BACKGROUND

Occupational health laws must recognise the constitutional requirement of substantive equality, and its role in 'the progressive realisation' of the rights provided by Section 27.

OBJECTIVES

Our main aim is to review current South African occupational health law (vis-à-vis workers' constitutional rights) in relation to hearing loss. We focus on gaps in the law regarding occupational hearing loss in South Africa.

METHOD

Our review of legal texts relies on experience as a methodological device augmented by the use of a critical science. Guided by literature or evidence synthesis methodologies, South African primary and secondary laws were reviewed along with unpublished (non-peer-reviewed) grey literature. An established six-step framework guided our thematic analysis. A semantic approach aided the critical interpretation of data using the Bill of Rights as a core analytical framework.

RESULTS

Four themes are discussed: (1) separate and unequal regulatory frameworks; (2) monologic foregrounding of noise; (3) minimisation of vestibular disorders; and (4) dilution of ototoxic agents. The highly divided legal framework of occupational health and safety in South Africa perpetuates a monologic 'excessive noise-hearing loss' paradigm that has implications for the rights of all workers to equal protections and benefits. There is a need to harmonise occupational health and safety law, and expand the scope of hearing-protection legislation to include the full range of established ototoxic hazards.

CONCLUSION

Occupational audiology is dominated by efforts to address noise-induced hearing loss. A 'noise' despite the reality of workers' exposures to a range of ototoxic stressors that act synergistically on the ear, resulting in audio-vestibular disorders.
