1 Noise Induced Hearing Loss and Hearing Conservation in 8 Primary Iron and Steel Companies in South Africa Presenters: Dr Odette Abrahams Gabriel Mizan
2 Background Noise: Sound that is undesirable, either because it annoys, distracts or interferes with those hearing it or because it has the potential to damage the hearing mechanism of those exposed to it SA Dept of Mineral and Energy (2000)
3 Noise Induced Hearing Loss (NIHL) Cumulative, permanent loss of hearing that develops gradually after months or years of exposure to high levels of noise Commonest compensable occupational disease globally One of the major avoidable causes of permanent hearing impairment worldwide WHO estimated that occupational NIHL costs approximately 0.2% to 2% of the GDP of developed nations
4 Factors Affecting Employees Susceptibility to NIHL Intensity of the noise (db) Temporal pattern of the noise (continuous, intermittent) Spectral pattern of the noise (frequency content) Duration of exposure Individual susceptibility to noise (age, ear infection, certain medication)
5 Statutory Requirements NIHL Regulations, promulgated under the OHSAct 85 of 1993 require the employer to implement HCP when workers are exposed to noise rating limit > 85 db (A) Compensation for Occupational Injuries and Diseases Act No 130 of 1993 compensable at or above PLH of 10 % as per Schedule 3 Circular Instruction 171 provides further guidance on compensation of employees
6 The Study NIOH was commissioned by the DoL to investigate noise exposure levels and NIHL in the primary Iron and Steel in South Africa Iron and Steel industry in one of the largest employers in SA with approximately employees South Africa is the 21 st largest crude steel producing in the world (7.6 m tonnes /year) Iron and Steel manufacturing is one of the noisiest industries and NIHL is common
7 Study Objectives 1. To verify the current designation of noise zones as described in companies occupational hygiene reports 2. To verify workers noise exposure levels by taking spot area measurements and personal noise exposure (dosimetry) 3. To analyse and audit current hearing conservation practices 4. Based on company records, to determine the extent of NIHL diagnosed by the companies over the past decade
8 Study Objectives 5. To verify records of current hearing threshold levels of workers by independently conducting audiometric testing 6. To compile recommendations for improvement of existing hearing conservation practices that can be implemented in the South African iron and steel industry 7. Based on best practices and expert advice, to develop a standard inspector checklist for noise in the iron and steel industry
9 Methodology
10 Methodology Cross sectional survey in 8 major iron and steel companies across SA Company Type of industry No of permanent No of contract employees employees Company A Primary steel plant Company B Primary steel plant Company C Primary steel plant Company D Secondary steel plant Company E Primary steel plant Company F Primary steel plant Company G Primary steel plant Company H Primary steel plant
11 Phase 1: Occupational Hygiene Study Walkthrough / task observations Interviews with H&S personnel, workers, clinic Area (spot) noise measurements Personal noise measurements (dosimetry) Review of previous noise survey reports and other relevant documentation
12 H&S Manager Questionnaire Covered various aspects of HCP including: Information and training Assessment of exposure Survey report and recommendations Medical surveillance Hearing protection equipment Policies and procedure
13 Worker s Interview Questions When were you last given training on noise? What are the main health risks of noise? Do you use hearing protection in your job? What type of hearing protectors do you use? Will you show me how do you put on hearing protectors correctly? When last did you have a hearing test? Do you experience any difficulties with your hearing? Do you have any concerns regarding noise in this workplace? Input / Observation
14 Phase 2: Occupational Medicine Hearing conservation Policy ý Interview check list used ý Copy of the company policy ý Interview was then compared to the written policy Medical Record Review Review of NIHL Audiometric verification
15 Response Rate Company Response rate in the chosen department Response rate in the NIHL employees Company A 100% 100% 56.7% Company B 100% 100% 66.7% Company C 100% a 89% Response rate for audiometric retesting Company D Not ascertained b Company E 63.4% 77.8% 77.4% Company F 42.6% 17.1% 56.8% Company G 38.7% 0% 83.3% Company H 66.7% 100% 50% a Employee records were available but not all were reviewed due to time constraints. b Employees consent for review of records was only concluded during the survey and hence a random sample could not be obtained.

35 Audiometric verification Aim: To compare a sample of audiograms done inhouse at each company with audiograms done by an external service provider on the same employees.
36 Audiometric verification A B C D E F G H Audiograms for comparison Concordant db difference db difference db difference >40 db difference
37 Limitations Industrial action affected response rate adversely OH measurements could not be done of every activity Incomplete medical records Extent of NIHL company records of cases over the past 10 years were used (underestimation) Reliance on companies to provide cases of NIHL (validation) Only permanent employees
38 Limitations Audiometric verification Currently no reference body for audiometric testing in the workplace No gold standard testing facility Measured repeatability rather than of validity External provider chosen based on calibrated equipment and a national footprint Many factors affect repeatability however this indicates that a review of quality assurance and testing procedures by in house testers is required
39 Conclusion All companies included in this survey had areas of noise exposure above the legislated level of 85dB(A) which put a number of employees at risk of developing NIHL Difference between the companies lies in the effective implementation of the hearing conservation programme Highlights the need for proper implementation of hearing conservation practices known to be effective and establishment of effective monitoring and evaluation systems
