COTRAL Laboratory have designed new packaging for their Optimum and Excellium packs. Better suited, more practical, readily identifiable and recyclable, it has many arguments in its favour!
Verify compliance of the COTRAL protections and check that your employees are properly protected if they wear their protections 100% of the time spent exposed to noise (according to standard EN 458).
The scientific studies show that deviations exist between the certification measurements of the protectors performed in a laboratory and the reality "in situ". This is why the referent certification bodies (INRS, IFA...) recommend reductions on the results obtained in the laboratory in order to have a predictive assessment of the attenuation of the protectors.
These results however remain mean results.
The outcome : individuals on either side of this mean will be adequately or even excessively protected, whereas others will not benefit from adequate attenuation and will be exposed in this case to a noise risk without being aware of it.
