HINESBURG, Vt. (AP) — A road was closed for several hours Wednesday while more than a dozen state and local police, federal agents and hazardous material experts investigated a possible methamphetamine lab that came to their attention after a man was injured in an explosion the day before.

There was no immediate threat to the public along Texas Hill Road, but the road was closed as a precautionary measure while officials investigated, police said.

Jacob Berino, who was injured in the blast, was reported by Hinesburg police to be in fair condition at Fletcher Allen Health Care in Burlington.

The Burlington Free Press reported that the 19-year-old Berino was a former honor roll student at Champlain Valley Union High School in Hinesburg.

Hinesburg police and fire departments initially received a 911 call Tuesday afternoon seeking medical assistance for an injured man. Berino was found when emergency responders arrived, police said

Neighbors said they heard a ‘‘pop,’’ which sounded different from gunfire.
