HAZMAT technicians were on the scene of North Street just off Highway 205 in Guntersville beginning at about 10:30 Thursday morning, after some city sanitation workers heard a boom in the back of their garbage truck.
HAZMAT technicians aren't taking any chances, but we were able to talk with Guntersville Fire Department's Public Information Officer Jim Moon on the scene, and he told us what happened.
He said two sanitation workers were picking up trash this morning along North Street in Guntersville.
They threw a bag in the back of the truck and compacted it, when they did they heard a poof and saw a bluish color smoke coming from the back of the truck.
Moon says they're not exactly sure what the chemical is at this point, but believe it could be muratic acid, a mild form of hydrochloric acid.
Several homes in the area were evacuated for safety reasons.
The two sanitation workers complained of shortness of breath, nausea, and chest pain.
They were taken to Marshall Medical North, where we're told they are o.k.
