The Health and Safety Laboratory (HSL) has published a new research report focusing on the noise emission of sanders and polishers, which has highlighted certain problems with regard to data supplied by manufacturers with regard to the noise levels of tools.
The Control of Noise at Work Regulations 2005 state that employers may use manufacturers' tool data to assess the risk to their employees from exposure to noise.
The objectives of the project were to:
- measure the noise emission of the tools supplied by the manufacturers and compare these to the manufacturers' declared emission, if stated
- determine whether tools with a declared noise emission have been tested in accordance with the most appropriate test code
- compare the noise emission of the electric tools when tested according to the pneumatic standard
- comment on the noise test codes for the family of tool under test, eg to ascertain whether tools should be tested with all the accessories attached
- investigate the link between the manufacturers' declared emission and the workstation emission.
The report found that airborne noise emission data varied greatly between manufacturers and between different tools supplied by the same manufacturer. The researchers also found that the methods used and the quality of data supplied was not always consistent or transparent, making it difficult to compare machines.
The report concluded that:
- tool manufacturers need to be alerted to their duties with regards to provision of airborne noise emission data
- standards bodies and tool manufacturers should be advised that reproducibility of declared emissions is not sufficiently high
- end-users of tools should be alerted that the declared noise emissions may not sufficiently reflect the risk to the worker
- measurement should be at the location of the operator's ear
