The Workplace exposure limits for airborne contaminants (WEL list) includes advisory notations for some airborne contaminants, in addition to the mandatory exposure limits. These advisory notations provide information about additional risks that some airborne contaminants pose.
An ototoxicity notation (‘OTO’) has been introduced for some airborne contaminants in the WEL list.
Exposure to an airborne contaminant with an ‘OTO’ notation can increase the risk of hearing loss, especially if a worker is also exposed to noise at the same time. Exposure to ototoxic substances can occur through skin absorption, inhalation or ingestion.
A person conducting a business or undertaking (PCBU) must eliminate or minimise the risk of ototoxic substances in the workplace, so far as is reasonably practicable.
For more information on managing the risk of ototoxic substances, see the model Code of Practice: Managing noise and preventing hearing loss at work.
