A registered nurse has described conditions at a south-west mine site as 'disgusting' and lodged a formal complaint with the Department of Mines and Petroleum.
Jeremy Clarke was employed to work as a contract labourer at BHP Billiton's Marradong bauxite mine near Boddington early this month.
Mr Clarke claims he was bullied by his supervisor and ordered off site after asking for water and a hat which complied with safety standards.
He says he was shocked by the conditions.
"The conditions out there are inhumane, absolutely inhumane, the conditions that we're working under," he said.
"I'm absolutely astounded that we can still allow people to work in those conditions, it's like come on guys wake up to yourselves." The Department of Mines sent a safety officer to the site for inspection after receiving the complaint.
It says the officer found some health and hygiene problems needed to be rectified and issued the operator with an improvement notice for the area of the mine Mr Clarke was working in.
BHP Billiton says it received the notice, but is yet to formally respond to the department.
The company says it investigated Mr Clarke's concerns and believes they are unfounded.
