Text For Citation: 01 Item/Group: 006B Hazard:

29 CFR 1910.119(j)(4)(iii): The frequency of inspections and tests of process equipment to maintain its mechanical integrity, was not consistent with applicable manufacturers' recommendations and good engineering practices, and more frequently if determined to be necessary by prior operating experience. a) On or about 10/20/2015, at the Diversified Foods and Seasonings facility located in Madisonville Louisiana, the employer failed to ensure that safety inspections for the ventilation system in the engine room was conducted at a frequency consistent with recognized and generally accepted good engineering practice such as IIAR Bulletin No.109 and the employer's Mechanical Integrity (MI) procedure. This condition exposed employees to the hazards of inhalation of ammonia and fire/explosion. b) On or about 10/20/2015, at the Diversified Foods and Seasonings facility located in Madisonville Louisiana, the employer did not ensure that inspections and tests are conducted at a frequency consistent with recognized and generally accepted good engineering practice such as IIAR Bulletin No.110 and the employer's Mechanical Integrity (MI) procedures for specific safety systems that include but are not limited to the following: 1. Oil Pressure Differential Cut Outs for the Compressor, HS-1 2. High and Low Pressure Cut Out for the compressor, HS-2 3. High Temperature Cut Out for Compressor, BC-1 4. High and Low Level Controls for Re-circulator, V-4 5. High and Low Level Controls for High Pressure Receiver, V-1 6. Emergency Stop Buttons for the ammonia refrigeration system This condition exposed employees to the hazards of inhalation of ammonia and fire/explosion. c) On or about 10/20/2015, at the Diversified Foods and Seasonings facility located in Madisonville Louisiana, the employer did not ensure that inspections and tests are conducted at a frequency consistent with recognized and generally accepted good engineering practice such as the employer's Mechanical Integrity (MI) procedures and IIAR Bulletin No.110 for compressors and pumps that include but are not limited to the following: 1. High Stage Compressor, HS-1 2. Booster Compressor, BC-1 3. Recirculator Pump, RP-1 4. Recirculator Pump, RP-2 This condition exposed employees to the hazards of inhalation of ammonia and fire/explosion. d) On or about 10/20/2015, at the Diversified Foods and Seasonings facility located in Madisonville Louisiana, the employer did not ensure that inspections and tests are conducted at a frequency consistent with recognized and generally accepted good engineering practice such as IIAR Bulletin No.110 and the employer's Mechanical Integrity (MI) procedures for piping that include but are not limited to the following: 1. 10" LTRS (Low Temperature Recirculation suction) header 2. 6" HSD (High Stage Discharge) from High Stage Compressors to Evaporated Condensers (EC-1&EC-2) 3. 3" HPL (High Pressure Liquid) from the King Valve to the Intercooler V-3. 4. 6" BD (Booster Discharge) from Booster compressors to the Intercooler V-3. This condition exposed employees to the hazards of inhalation of ammonia and fire/explosion.
