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

OSH ACT of 1970 Section (5)(a)(1): 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: a) At the De-Ethanizer Pad, on or about December 13, 2018 - Employees pumped a solution of heated water and descaler into Stabilizer Tower T-511 with a vacuum tanker truck. A vacuum tanker truck removed a load of waste material from Stabilizer Tower T-511 after the solution soaked in Stabilizer Tower T-511. Stabilizer Tower T-511 waste material was moved by the vacuum tanker truck to the De-Ethanizer Pad where Frac Tank A2363 was staged. Prior to off-loading Stabilizer Tower T-511 waste material into Frac Tank A2363, 405 barrels of "A" slug catcher liquid was taken out of Frac Tank A2363 leaving a residual amount of "A" slug catcher liquid leftover in Frac Tank A2363. While off-loading Stabilizer Tower T-511 waste material into Frac Tank A2363, vapors escaped Frac Tank A2363 through an opened manway cover and the vacuum tanker truck through the pump exhaust. Employees were exposed to these vapors with sources of ignition including, but not limited to, static electricity, running propane heater trucks, a running vacuum tanker truck, hot heater coils on the propane heater trucks, heater exhaust on the propane heater truck, hot water outlet pipe on the propane heater truck, and an air heater in the area surrounding Frac Tank A2363.
