An independent federal agency investigating chemical accidents to protect workers, the public, and the environment.
Implement a mechanical integrity program for the electric arc furnace and cover, including preventive maintenance based on periodic inspections, and timely replacement of the furnace cover. At a minimum, the program should include factors such as leak detection and repair and refractory lining wear.
Establish a committee to evaluate and develop a standard that defines the safety requirements for electric arc furnaces operated with flammable materials and low oxygen atmospheres. At a minimum, establish requirements that electric arc furnaces containing flammables have: • Adequate safety instrumentation and controls to prevent explosions and overpressure events; • Mechanical integrity and inspection programs; • A documented siting analysis to ensure that control rooms and other occupied areas are adequately protected.
Modify the design and procedures for the electric arc furnace and related structures including the control room to comply with the NFPA standard developed per R1 of this case study.
