Text For Citation: 01 Item/Group: 001 Hazard: ELECTRIC

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 the frequency of inspections and tests of Durr DC 12-18 Exhaust Air Purification System, Incinerator No. 5 (propane fueled), were not consistent with applicable manufacturers recommendations exposing employees to the hazard of gas explosion: a) Frame area, Durr DC 12-18 Exhaust Air Purification System, Incinerator No. 5: 1) Incinerator No. 5, Maxon Combustifume Type CF-5 Burner: Burner condition was not checked weekly as required by manufacturer Durr Maintenance and Service Instructions, nor was the burner safe-functioning checked at least once a year as required by manufacturer Durr Maintenance Instructions for Gas Burner Installed in Exhaust Air Purification System, on or about December 7, 1997. 2) Incinerator No. 5, Burner End, Honeywell Primary Electrical Control No. RA 8906 Flame Relay in Electrical Control Cabinents: Monthly inspections required by manufacturer Durr Functional Check-up of the Safety Equipment of the DC Gas Firing System Instructions did not assure that a dust protection cover required by the manufacturer to protect the Honeywell Primary Electrical Control Flame Relay against dust contamination was in designated place covering the control, nor were other electrical control equipment protected against dust contamination by assuring filters required by manufacturer at cabinet ventilation openings were in place, on or about December 7, 1997. 3) Incinerator No. 5, Gas Regulation Train, Honeywell Low Pressure Gas Switch Tag No. 113: Monthly inspections required by manufacturer Durr Functional Check-up of the DC Gas Firing System and Durr Maintenance and Service Instructions for the Honeywell Low Pressure Gas Switch Tag No. 113 did not assure that the equipment was free from any impediments. A "Dime" (10 cents) with a hole drilled through the center, was inserted in the 1/2 inch elbow union, limiting or preventing pressure communication to the pressure gauge used to measure the regulators outlet pressure, on or about December 7, 1997. 4) Incinerator No. 5, Gas Regulation Train, Rockwell (Equimeter) Regulator No. 121-12, Tag No. 112: Monthly inspections required by manufacturer Durr Functional Check-up of the Safety Equipment of the DC Gas Firing System and Durr Maintenance and Service Instructions did not assure that the upper case vent piping for the Rockwell (Equimeter) Regulator No. 121-12, Tag No. 112, was not tied into common vent piping with two Maxon shutoff valves, a red cap vent valve and twoHoneywell gas pressure switch vents, but vented individually as recommended by the manufacturer, on or about December 7, 1997. 5) Overhead duct system between No. 5 Bruckner Tenter Frame and No. 5 Durr Incinerator: Quarterly inspections required by manufacturer did not assure that the inside of the ductwork was clean and operated as designed, on or about December 7, 1997. Among other methods, one feasible and acceptable abatement method to correct this hazard are: 1) Ensure that the frequency of inspections and tests are consistent with applicable manufacturers recommendations and good engineering practices, and are done more frequently if determined to be necessary by prior operating experience. 2) Document each inspection and test that has been performed on equipment. The documentation should identify the date of the inspection or test, the name and signature of the person who performed the inspection or test, the serial number or other identifier of the equipment on which the inspection or test was performed, a description of the inspection or test, and the results of the inspection or test.
