The engineering and maintenance that takes place in healthcare facilities presents potential safety risks for front-line technicians, from arc-flash incidents to threats related to power tool use. Tool-related risks also extend to workers on construction projects.

Twelve construction workers are in the hospital after a carbon monoxide leak at a construction site in Saratoga Springs, Utah, on April 6, according to ABC 4. The construction crews were using gas-powered tools in a two-story building that didn’t have a ventilation system, which caused a build-up of carbon monoxide.

Nine people were transported by ambulance to local hospitals, and three other people drove themselves to local hospitals. Officials say a cement crew was working on the first floor of the building, while an electrical crew was working on the second floor of the building.
