29 CFR 1910.119(j)(4)(i): The employer did not perform inspection and tests on process equipment: a) On or about June 21, 2019, the employer failed to conduct piping inspections and tests in the 433 Hydrofluoric (HF) Alkylation Unit on piping components that were constructed/installed with older carbon steel materials that are more susceptible to HF acid corrosion. The employer did not conduct testing and inspections to determine whether the structural integrity of following piping sections is suitable for continued service: 1. F series piping HC-2501-14 (T-6 Overhead) untested/uninspected carbon steel elbow downstream from N0130 CML 005 (See ISO 433-TML-N-01 Sh 01 of 6) 2. F series piping HC2650-2 untested/uninspected carbon steel elbow downstream of V-11 Depropanizer Accumulator, D0510 CML 002 (See ISO 433-D-04 Sh 01 of 4) 3. F series piping HC4510-6 untested/uninspected carbon steel elbow downstream of V-35A Defluorinator and M0210 CML 080. (See ISO 433-M-02 Sh 03 of 3) 4. F series piping HC2736-6 (Propane Vapor from V-13A/B Propane Defluorinator to E-23), untested/uninspected carbon steel elbow downstream from LO210 CML 055 (See ISO 433-L-02 Sh 02 of 2) 5. F series piping HC4506-4 (Butane Liquid from E-39 Defluorinator Feed/Condenser to V-36 Flare KOH Treater), untested/uninspected carbon steel elbow downstream from M0310 CML 011 (See ISO 433-M-03 Sh 01 of 9) 6. F series piping HC2335-24 untested/uninspected carbon steel elbow downstream JO410 CML 005 which is downstream of the T-5 Isostripper (See ISO 433-J-04 Sh 01 of 1) 7. F series piping HC2539-12 (Depropanizer Btms from/to T-6 thru E-17A/B Reboiler), untested/uninspected carbon steel elbow downstream from N0210 CML 020 (See ISO 433-N-02 Sh 01 of 7) This hazardous condition exposed employees to fire, explosion, toxics, and corrosives hazards.
