APACHE JUNCTION, Ariz. -- Several Apache Junction residents who had to evacuate their homes due to a hazmat situation at a metal recycling business were allowed to return to their houses Thursday evening.
Firefighters said employees reported the leak Thursday afternoon.
No injuries were reported, but more than 40 people had to be evacuated from both nearby businesses and homes in the area of Southern and Tomahawk.
Investigators eventually determined that the substance that led to the evacuation was a gas used for welding, which was leaking from a cylinder.
The leak occurred as the cylinder was being moved.
Fire crews remained on scene for about an hour after allowing residents to return.
