The Ultimate Safety Device — A Load Scale on an EOT Crane
Robert L. Emery and Gerald D. Bruder, ArcelorMittal Burns Harbor, Burns Harbor, Ind. (RobertL.Emery@arcelormittal.com, Gerald.Bruder@arcelormittal.com)
In organizations where “close call” events are reported and investigated, accident prevention personnel are able to take steps to prevent fatalities. A case study demonstrates how one organization made this significant improvement. |

Delayed Cracking and Safety Considerations for Forged Steel Work Rolls
William J. Hill, ArcelorMittal Dofasco Inc., Hamilton, Ont., Canada
Delayed crack propagation is initiated under high-stress conditions. Principles of acoustic emission and other non-destructive techniques were used to detect crack propagation and create a safer working environment for those handling damaged forged steel work rolls. |

Air Permitting in the Steel Industry: Dodging Potholes in a Deteriorating Road
Robert R. Geddis, Air Pollution Regulatory Services, Melbourne, Fla. (bgeddis@mindspring.com)
The author, calling on 45 years of experience, describes the steel industry’s dramatic progress controlling air pollution despite increasingly burdensome and questionable permit requirements. In the second part, the author recommends some practical ways to negotiate safer, less costly permits. He critically examines controversial permit issues such as mercury, control technology, emission limits and factors, PM2.5 and condensables, and continuous and preconstruction monitoring. The paper ends with the author’s modest suggestion how regulatory agencies could get back to the ideals of the Clean Air Act. |
