Health surveillance is a requirement under ‘The Control of Noise at Work Regulations’, 2005 for workers who are regularly exposed to noise over the upper exposure action value of 85 dB (A). Other workers should have health surveillance provided where their exposure is either:
1. Between the lower exposure action value of 80 dB (A) and the upper value of 85 dB (A) and the individual may be particularly sensitive to noise.
2. Or occasional exposure above the upper exposure action value and the individual may be particularly sensitive to noise.
Sensitivity may be indicated by previous audiometry, medical history, history of exposure to noise above 85 dB (A) or in where there is a family history of early deafness.
