Williston, Vt.- "It was a pretty catastrophic collapse of the entire rafter system as well as the side walls of the building."
A routine job gone wrong. After attempting to put in the final truss of the roof for this salt shed for Williston department of public works, the roof collapsed.
“There were in fact four people injured, we had to call for a fourth ambulance,” said Williston Fire Chief Ken Morton.
South Burlington, Essex, Saint Mikes and Williston EMS and fire departments worked together and even had to help one worker who was trapped.
“All though all four had varying levels of injury, none certainly appeared to be life threatening," Morton said.
All four were in stable condition when they checked into Fletcher Allen Medical Center.
The environment on the site, may have played a factor in their good fortune.
The fall from the roof to the ground was 21 feet, but it's what the workers landed on that prevented major injury.
"The building is pretty well surrounded by sand, so they had a semi soft landing versus landing on concrete or gravel," Morton said.
Two workers were treated and released from Fletcher Allen, while the other two have been admitted at least for the night.
