Your legal duties
New regulations for Occupational Health and Safety came into effect on 18 June 2017.
The OHS Regulations contain specific requirements for the control of noise that is above the exposure standard. These obligations are addressed in Chapter 3 (Part 3.2) of the regulations.
The regulations impose obligations on employers.
As an employer, you must provide for an employee to have an audiological examination if they've experienced a reduction in hearing level of 15 decibels or greater of any two tests carried out under Regulation 37 (i.e. over a two year period).
