The identity of the man who died at a Pilbara iron ore site earlier this week has been released, with his employer revealing he was a young father of two.

Kieren McDowall was killed on Monday afternoon after an incident at the Ken's Bore site, owned by miner Mineral Resources as part of the broader Onslow Iron project.

Mr McDowall's family has released a photo of him, but asked for privacy as they mourn his death.

Mr McDowall was a contractor for AAA Asphalt Surfaces. The company's managing director Frank Italiano said he felt "profound sadness" at losing his colleague.

"I extend my deepest condolences to Kieren's family and friends; in particular his partner Bella, their two young children, his parents Kylie and Craig, brothers Matthew, Jayden and Hamish and extended family," Mr Italiano said.

"We are all devastated by this incident.

Mr Italiano said the company would work with authorities as they investigated the incident.

Inspectors from the WA Department of Mines, Industry Regulation and Safety travelled to the site yesterday.

Police have described the death as non-suspicious.

Industry safety 'shocking', union says

Mr McDowall's death is the fourth fatality in Western Australia's mining industry since October 2022.

Australian Workers Union (AWU) WA secretary Brad Gandy said the union was shocked and saddened by another fatality on a Pilbara mine site.

"Unfortunately, this is the fourth fatality on a West Australian mine in just 12 months," he said.

"Despite repeated calls to improve the industry's safety culture and overall safety standards."

Mr Gandy said every worker deserved to come home to their families after their shift.

"Mining is an inherently dangerous industry and safety should be the highest priority in the sector; from workers, to employers, to state and federal governments," he said.
