CBH fatal accident site remains closed

A grain site in Western Australia's Mid West region where a contractor was killed in an accident is expected to remain closed as investigations continue.

The man was carrying out maintenance work at the CBH Group site in Northhampton on Tuesday when he died.

The site was shut down immediately, as well as the entire CBH network, which reopened at 6am (WST) on Wednesday.

"This is a tragedy and our thoughts are with the family and friends of those involved," the grain co-operative said in a statement.

"CBH wants to take time to allow employees and contractors the opportunity to absorb this information and to refocus on safety."
