Assessing noise risks

In occupational health and safety, noise hazards often lurk in the background, posing risks to workers and the public across various industries. Understanding these hazards, identifying the most at risk, assessing exposure levels, and implementing an effective plan are paramount to safeguarding employee well-being and ensuring your work environment complies with statutory requirements.


Noise Hazards: Unveiling the Risks

Noise hazards encompass excessive or prolonged exposure to loud sounds that can harm auditory health. From construction sites to factories, noise hazards manifest in diverse work settings. Workers directly operating noisy machinery, tools, or equipment are particularly vulnerable to these hazards. However, ancillary staff working near such environments are also susceptible to noise-related health issues.


Identifying the Likely Noise Exposure Level

Determining the likely noise exposure level is essential for understanding the risks and providing appropriate preventive measures. Employers can use sound level meters to measure noise levels in decibels (dB) across different work areas. These measurements will identify the intensity and duration of noise exposure experienced by employees. It is essential to review the information and understand any areas or activities where noise exceeds permissible limits.


Mitigating Noise Hazards: Elimination and Reduction Strategies

Several options are available for addressing noise hazards. The idea is to eliminate sources of excessive noise and reduce exposure levels for at-risk individuals.


Engineering Controls

Implementing engineering controls involves modifying machinery or workplace layouts to minimise noise emissions. This could include installing noise-reducing barriers, enclosing loud equipment, or utilising quieter machinery and tools.

Administrative Controls

Administrative controls focus on altering work practices and schedules to limit noise exposure. Strategies may include rotating employees through quieter tasks, scheduling noisy activities during off-peak hours, or enforcing regular breaks to reduce cumulative exposure.


Personal Protective Equipment (PPE)

Appropriate PPE becomes essential when engineering and administrative controls are insufficient to mitigate noise hazards. Earplugs or earmuffs effectively attenuate noise and safeguard workers’ auditory health. However, PPE should complement, not substitute, other control measures.


Recording Actions: Documenting Progress and Compliance

You should maintain comprehensive records of noise assessments, exposure levels, and mitigation measures for regulatory compliance and continuous improvement. Documenting actions to address noise hazards demonstrates an organisation’s commitment to worker safety. Regular reviews of these records help identify emerging risks and adjust to enable you to consider potential mitigations.


In conclusion, employers are legally obligated to protect workers from auditory impairments and promote a safe and conducive work environment. Organisations can effectively navigate the complexities of noise hazards and prioritise employee well-being by systematically assessing risks, quantifying exposure levels, implementing mitigation strategies, and diligently documenting actions taken.
