GRANDVIEW, Iowa (AP) — Firefighters in southeastern Iowa have rescued a worker from more than 200 feet up inside a 620-foot industrial chimney at a MidAmerican Energy plant.

The Muscatine Journal reports (http://bit.ly/2fib2NA ) that rescue workers were called to the Louisa Generating Station in Grandview late Tuesday afternoon to save an employee trapped 230 feet up. The Muscatine Fire Department says it was the first time its team conducted a high-angle rescue outside of training events.

To reach the trapped employee, the team made its way up interior ladders and skywalks and used a system of ropes to lower the employee down in extreme heat and low visibility inside the chimney. The rescue effort took six hours, and the employee was safely removed. One firefighter suffered a minor injury during the rescue.
