Understanding Noise Hazards in the Workplace

Understanding Noise Hazards in the Workplace

Noise is an inherent part of many working environments, but excessive exposure to noise can have serious consequences. Beyond the risk of permanent hearing damage, unmanaged noise can impact productivity, increase absenteeism, and lead to costly legal repercussions.

The Health Risks of Noise

Exposure to high levels of noise over time can result in gradual hearing loss, while sudden, extremely loud sounds may cause immediate damage. For employees, this can mean a lifetime of hearing problems, while for businesses, it can result in reduced productivity and legal liabilities.

Legal Responsibilities for Employers

Under the Control of Noise at Work Regulations 2005, employers are required to take specific steps to manage workplace noise. These include:

• Assessing the risks posed by noise to employees.
• Taking action to reduce noise exposure.
• Providing hearing protection if noise cannot be reduced adequately by other means.
• Ensuring noise exposure limits are not exceeded.
• Informing, training, and instructing employees about the risks and control measures associated with noise.
• Conducting health surveillance where employees are at risk of hearing damage.

HSE Inspections and Compliance

In line with their inspection strategy, the Health and Safety Executive (HSE) is currently visiting businesses to assess how effectively noise is being managed. These inspections often highlight areas for improvement and may extend beyond noise management to include other occupational health risks, such as asbestos management. Discussions with various businesses suggest that these broader inspections can uncover multiple compliance gaps, underscoring the importance of a comprehensive approach to workplace health and safety.

Understanding Noise Levels

Understanding Noise Levels

The Regulations outline clear thresholds for action and legal limits:

• Lower Action Values: Daily/weekly exposure: 80 dB(A) Peak sound pressure: 135 dB(C) Actions: Risk assessment, employee training, and making hearing protection available.
• Upper Action Values: Daily/weekly exposure: 85 dB(A) Peak sound pressure: 137 dB(C) Actions: Noise reduction measures and mandatory use of hearing protection.
• Exposure Limit Values (which must not be exceeded): Daily/weekly exposure: 87 dB(A) Peak sound pressure: 140 dB(C)

Exemptions

The Regulations do not apply to:

• Public exposure to noise from non-work activities or voluntary attendance at noisy events.
• Low-level nuisance noise that does not pose a risk of hearing damage.

Does Your Workplace Have a Noise Issue?

Certain scenarios may indicate the need for action:

• Employees must raise their voices to communicate when two metres apart.
• Powered tools or machinery are used for extended periods.
• Work is conducted in industries such as construction, entertainment, or manufacturing.
• Loud impacts or explosive noises, such as hammering or pneumatic tools, are present.

The Importance of Noise Management

Proactively managing noise in the workplace safeguards employees’ health, improves productivity, and ensures compliance with legal obligations. It is not just about protecting hearing—it is about fostering a safer, healthier work environment for all.

Noise risks require careful attention, but the benefits of effective management—for individuals and organisations—are significant.
