Hazardous area scaffolder

My husband just completed his hazardous scaffolding building class. Six days of intense learning and building steel frames. His training will take him to a job this spring at a nuclear power plant where he will be removing steel floor grids that are above radio-active water at the plant. Building down from the top of the floor grid hanging steel baskets to support other workers that will be working down in the basket to repair valves. He's not looking forward to this but working three weeks there is three months worth of regular income. Hope for the best.
