WorkSafe is investigating the work-related death of a shearer at Katrine, between Northam and Toodyay.
The man was reported to have been placing wool into a wool press yesterday when he was caught in the machinery.
WorkSafe investigators examine the circumstances of incidents in workplaces with a view to ensuring compliance and preventing future incidents of a similar nature.
WorkSafe WA Commissioner Darren Kavanagh said any work-related death was a tragedy, and relayed his sincere condolences to the man's family.
"The agriculture industry has unfortunately experienced six deaths over the past ten months, and this needs to improve," Mr Kavanagh said.
"Agriculture frequently appears as one of the top three industries for workplace deaths, and there's an increasing need to give greater priority to safety and health."
