Controlling workplace noise is crucial to prevent hearing loss. Setting up hearing protection zones lets staff know when to wear ear defenders or earplugs.
The Control of Noise at Work Regulations set out legal requirements for employers to protect employees against harmful noise exposure. Before using personal hearing protection, the risk should be eliminated or reduced as much as possible using other control measures.
If noise in any part of the workplace remains at or above an upper exposure action value, the area must be designated a hearing protection zone.

Hearing protection zones may be permanent or temporary, in fixed locations or mobile, depending on the work activities and noise source.
The area needs to be demarcated and identified with ‘ear protection must be worn’ signs (as shown in The Health and Safety (Safety Signs and Signals) Regulations 1996) at all entrances and appropriate places inside the zone.
Setting up hearing protection zones acts as a reminder for staff who need to wear ear defenders or earplugs during certain jobs or activities. It also ensures other people in the area and nearby are protected.
Access should be restricted where practical to prevent unnecessary exposure. The employer is responsible for making sure appropriate hearing protectors are worn at all times within the area.
Hearing protection zones are an effective way to manage hearing protection use in the workplace. They provide a visual reminder when PPE is required and restrict access to noisy areas. While the employer is ultimately responsible, training helps to educate staff and ensure hearing protectors are worn to combat exposure.
