UPDATE, 11AM: The company which employed two men killed in separate incidents three days apart has rallied to support their families.
The two men, both aged in their 30s, died in unrelated workplace-related incidents on the western Darling Downs last week.
Both men worked for the Toowoomba-based Neil Mansell Group.
The company's human resources co-ordinator Amy Belford said as the incidents remained under investigation, no formal comment was able to be made.
However, she said the men's families and colleagues were a priority.
"At this stage we don't have any formal comment to make given that it is under investigation," Ms Belford said.
"Right now the families and the people are our priorities.
"That's where our time and resources will be spent."

Two men, both aged in their 30s, were killed in two workplace-related incidents within three days in the western Darling Downs region.
