What happens if my workplace fails an occupational noise test?
If your workplace fails an occupational noise test, it means that noise levels exceed legal action or limit values set by the Control of Noise at Work Regulations 2005. This triggers legal duties for employers, and failure to act can lead to enforcement action by the Health and Safety Executive (HSE).
What “Failing” a Noise Test Means
- Noise exceeds 80 dB(A): Lower Action Value triggered.
- Noise exceeds 85 dB(A): Upper Action Value triggered.
- Noise exceeds 87 dB(A) (even after PPE): Legal Limit breached — serious non-compliance.
Immediate Actions Employers Must TakeIf Exposure > 80 dB(A) (Lower Action Value):
- Provide information and training on noise risks.
- Make hearing protection available.
- Consider offering health surveillance if there’s a risk of hearing damage.
If Exposure > 85 dB(A) (Upper Action Value): - Implement noise control measures (engineering or administrative).
- Provide and enforce the use of hearing protection.
- Mark and enforce Hearing Protection Zones with clear signage.
- Start health surveillance (regular hearing checks) for affected workers.
If Exposure > 87 dB(A) (Exposure Limit): - Must take immediate action to reduce exposure.
- Workers must not be exposed to noise beyond this level even when wearing hearing protection.
- Stop the work activity if necessary until compliant.
