Section 5(a)(1) of the Occupational Safety and Health Act of 1970: The %% employer did not furnish employment and a place of employment which were free from recognized hazards that were causing or likely to cause death or serious physical harm to employees in that employees were exposed to: (a) The hazards of bursting or failing components caused by an un- approved pressure vessel (known as the east impregnator) on March 16, 1992. The pressure vessel did not meet the requirements of ASME (Amerian Society of Mechanical Engineers) Boiler and Pressure Vessel Code Section VIII Rules for Construction of Pressure Vessels, Division 1 and State of Wisconsin Administrative Code. Department of Industry, Labor and Human Relations Chapters IHLR 41 and 42 Boiler and Pressure Vessels. For Example: A) ASME Section VIII Division 1 UG-125(A) Pressure Relief Devices: All Pressure vessels within the scope of this Division, irrespec- tive of size or pressure shall be provided with protective devices in accordance with the requirements of U.G.-125 through U.G.-136 and B) Wisconsin Administrative Code Chapter ILHR 41.94 Pressure relief devices required for unfired pressure vessels: 1) Every unfired pressure vessel shall be provided with or pro- tected by a pressure relief device set to relieve at or below the maximum allowable working pressure of the vessel. (b) The hazards of bursting or failing components caused by an un- approved pressure vessel (known as the east impregnator) on March 16, 1992. The pressure vessel did not meet the requirements of AMSE (American Society of Mechanical Engineers) Boiler and Pres- sure Vessel Code Section VIII Rules for Construction of Pressure Vessels, Divison 1 and State of Wisconsin Administrative Code. Department of Industry, Labor and Human Relations Chapters IHLR 41 and 42 Boiler and Pressure Vessels. For Example: A) Wisconsin Administrative Code Boiler and Pressure Vessels. Sub Chapter V Secondhand Vessels ILHR 42.45 Inspection and Testing of Secondhand Vessels. 1) Every secondhand vessel shall be inspected and given a hydro- static pressure test at one and one-half times the maximum allowable working pressure at its new point of installation location before it is placed in operation. (c) The hazards of bursting or failing components caused by an un- approved pressure vessel (known as the east impregnator) on March 16, 1992. The pressure vessel did not meet the requirements of ASME (American Society of Mechanical Engineers) Boiler and Pres- sure Vessel Code Section VIII Rules for Construction of Pressure Vessels, Division 1 and State of Wisconsin Administrative Code. Department of Industry Labor and Human Relations Chapters IHLR 41 and 42 Boiler and Pressure Vessels. For Example: A) Wisconsin Administrative Code Boiler and Pressure Vessels. IHLR 41.37 Maintenance: 2) Safe conditions. The inspector shall note conditions during internal inspection, external inspection, or hydrostatic pressure test and shall order changes or repairs which will place the boiler or pressure vessel in a safe working con- dition. Among other feasiable methods of acceptable methods to correct these hazards is to provide pressure relief valve at or below 100 PSI working pressure, hydrostatic test vessel, and assure that locking ring and worn locking lugs are maintained and/or repaired with periodic testing of safety limit switches.
