Environmental Site Services will help you meet all of your obligations to protect your workers from noise induced hearing loss.
Noise in the workplace is the major cause of hearing loss in Western Australia. Noise induced hearing loss can neither be reversed nor cured with sufferers often facing social isolation from communication difficulties.
Excessive noise in the workplace can also cause immediate problems including stress, high blood pressure, and sleep problems. Noise also presents a safety hazard as noise can interfere with communication, act as a distraction, and make warning alarms harder to hear.
The Occupational Safety and Health Act 1984 require the employer to provide as far as practicable a safe working environment and not expose employees to hazards. The Occupational Safety and Health Regulations 1996 states that persons in control of a workplace must not (as far as practicable) expose employees to noise exceeding exposure standards.
The Code of Practice for Managing Noise at Work places 2002 states that noise assessments are to be conducted where a noise hazard is identified and at intervals of 5 years from the initial survey or when there is a significant change in the work process, equipment, working area or shift arrangements.
Significant changes in in work areas which will change worker noise exposure include:
- Installation or removal of equipment
- Changes in workload of the equipment
- Modification of the building structure
- Changes in working arrangements where personnel may spend more time in noisy work areas/completing noisy tasks
Under Western Australian regulations the occupational exposure standard (action level) for workers not wearing hearing protection is:
a) 85 dB(A) averaged over an 8 hour period for noise exposure or
b) 140 dB(C) for peak noise or 140 dB(lin) peak noise for mine sites
Where employees are exposed to levels above the exposure standards it is a requirement under the regulations that hearing protection is provided and selected in accordance with AS/NZS 1269.3 and comply with AS 1270.
Workplaces with an 8 hour personal noise dose of 90 dB or equivalent; or one or more peak noise exposures of 140 dB or over are defined as a prescribed workplace and The Workers Compensation and Rehabilitation Act 1981 makes it compulsory for employers to arrange and pay for baseline WorkCover WA audiometric hearing tests. The tests must be completed within 12 months of commencing of employment (90 dB is equal to standing approximately one metre from an idling truck).
