RUSTENBURG — AMCU president Joseph Mathunjwa has demanded that mine management face personal and criminal accountability following a fatal sulphur dioxide gas leak at Impala Platinum's (Implats) Rustenburg operations.
According to IOL, the toxic gas escaped from the Mineral Processing Plant after a valve failure at the sulphuric acid plant. Eight employees were exposed to the leak. A 45-year-old plant cleaner collapsed near the site's clinic and later died, while the remaining seven workers received medical treatment for their exposure.
Mathunjwa calls for immediate investigation
AMCU called on authorities to immediately investigate maintenance practices, safety controls, and emergency preparedness at the Rustenburg operation. Mathunjwa described the incident as another preventable tragedy, stating that processing plants "cannot continue operating as slaughterhouses instead of safe workplaces."

He further stressed that the law must enforce real consequences for those whose negligence contributes to a worker's death, arguing that preventable workplace disasters will persist until decision-makers are held personally responsible. Sulphur dioxide is a toxic gas capable of causing severe respiratory complications and death. Its presence in industrial settings requires strict safety protocols and monitoring systems to safeguard workers from exposure.
Safety concerns follow recent fatalities at Rustenburg
The gas leak occurred shortly after Implats had already halted mining operations at the Rustenburg site to conduct a safety reset. The company suspended activities after two employees died in separate incidents during July 2025. Another miner died at the mine in 2023. Implats stated at the time that the shutdown was intended to give management the opportunity to review critical safety controls, engage directly with employees, and reinforce workplace discipline.
The company added that the intervention demonstrated its commitment to prioritising health and safety above all other operational considerations. The latest fatality raises fresh questions about the effectiveness of those safety measures, coming so soon after the company's own acknowledgement that urgent corrective action was required at the site.
