SINGLE BOLTING PERSISTS DESPITE DANGERS AND DECADES-OLD RULE

Ironworkers and the steel erectors that employ them continue to violate the decades-old federal safety standard requiring structural steel to be secured with two bolts prior to release from the crane hoisting line, according to sources in the industry. While a few steel erectors say single bolting saves time, others say it imperils the workers and risks collapses like the one that killed three workers in the summer of 1997 at the Portland International Airport garage being erected by Midwest Steel. Exactly how much single bolting occurs is not clear, but some believe it is common. "Two-bolting was a fall-protection rule, not a structural rule," claims Michael J. Hines, safety director at Midwest Steel. "It was instituted in the days before we had tie-offs and was enacted to ensure that beams would not roll when guys stepped onto them."
