What Happened

A worker became seriously ill due to prolonged exposure to hazardous levels of cobalt dust, which was the result of a defective ventilation system failing to control dust emissions.

Despite repeated air and biological tests showing dangerous cobalt levels, the employer failed to rectify the ventilation issue, leading to the worker’s development of occupational asthma and elevated cobalt in his bloodstream.

Regulatory Findings

The NSW District Court found the company guilty of breaching sections 19 (“Primary duty of care”) and 31 (“Gross negligence or reckless conduct–Category 1”) of the NSW Work Health and Safety Act 2011.

Repeated tests showed that the workplace air exceeded cobalt exposure standards, and the company neglected to act on this evidence, exposing workers to significant health risks.

Sentences and Penalties

The Court sentenced the employer to a $1.2 million fine from a possible maximum of $3 million, highlighting the company’s reckless disregard for worker safety over several years.

SafeWork NSW’s investigation revealed severe failures in workplace safety management, underscoring the importance of compliance with WHS regulations.
