A man was killed Thursday when a prefabricated home collapsed at a work site in Millbrook, N.S.

Millbrook RCMP said a group of workers was preparing to move the structure at the site on Abenaki Road when it came down on the 34-year-old New Brunswick man just before 1 p.m.

Cpl. David Lilly said the man — who worked for a moving company in Chipman, N.B. — was underneath some cinder blocks trying to jack up the house when it collapsed on top of him.

"He had a crew of about five or six people here helping, from what I understand," he said.

A representative from Patterson Sales & Service Ltd. said the house was being used as a show home for the company and was recently sold.

Patterson Sales had hired S&S Mini & Modular Home Moving Inc. to prepare and move the structure.

Lilly said crews tried to use cranes to free the man. He was dead when police officers arrived on the scene.

Workplace safety officers are investigating.

There have now been 30 workplace fatalities in Nova Scotia this year.
