At 1:00 p.m. on September 27, 1993, a hydrostatic test crew operator and two helpers began testing 19 sections of 7 inch P-110 casing pipe at 9,500 psi. The activities were being conducted in the pipe testing building, adjacent to the pipe threading building and north of the sales and service office. The hydrostatic crew would roll the pipe onto the holding devices, check the drift (proper dimensions), apply thread dope, install the front header plug and rear "gun" plug, align the header plug bleed valve, fill the pipe with water, close the bleed valve, tighten the header plug, and assume their designated positions for pressure testing in accordance with pressure test specifications. After conducting the pressure test, employees would drain the water, remove the plugs, roll the pipe down the line, grease the threads, and stencil the pipe. Near 4:00 p.m. the crew was working on pipe section number 18. About 4:15 p.m., the pipe was filled with water and the crew began the pressure test. At 1,000 psi the header plug exploded blew out of the coupler on the pipe and struck Employee #1. Coworkers rushed to his aid and emergency medical services were notified. CPR was administered. Medical services arrived and transported Employee #1 to the hospital, where he died at about 5:00 p.m.
