AMCU's Mathunjwa demands criminal charges after fatal gas leak at Implats Rustenburg

The Association of Mineworkers and Construction Union (AMCU) is pushing for mine management to face personal criminal charges following a deadly gas leak at Impala Platinum’s Rustenburg facility. The union is demanding that negligence no longer be ignored after yet another workplace tragedy.

A failure in a sulphuric acid plant valve led to the release of toxic sulphur dioxide at the site's Mineral Processing Plant. Eight staff members were exposed to the dangerous fumes, resulting in one fatality and seven hospitalizations.

The victim, a 45-year-old cleaner, reportedly collapsed near the site clinic and later passed away. The surviving employees were treated for exposure to the gas, which is known to cause severe respiratory damage or death upon inhalation.

Demands for Safety Accountability

AMCU president Joseph Mathunjwa has voiced his outrage, calling for an urgent investigation into the mine's maintenance and emergency protocols. He insisted that industrial sites should not be allowed to function as "slaughterhouses instead of safe workplaces."

Mathunjwa argued that workplace disasters will only stop when there are real legal consequences for decision-makers. The union believes that holding individuals personally responsible for safety lapses is the only way to prevent future loss of life.

A Pattern of Incidents

This latest fatality is particularly concerning as it follows a recent "safety reset" at the Rustenburg operations. Implats had previously paused mining activities in July 2025 after two other employees died in separate accidents.

The mining giant had claimed that the temporary shutdown was a commitment to prioritizing health and safety. However, this new incident, following a previous death at the mine in 2023, raises serious doubts about the effectiveness of the company's internal safety reviews.

Authorities are now expected to probe whether the mine's safety controls were adequate. For now, the focus remains on the grieving family of the deceased cleaner and the recovery of the seven workers still affected by the toxic exposure.
