![]() ![]() Outside sits a VHF communication antenna that was designed to withstand a nuclear blast within two miles, in addition to a secondary antenna, an air-intake ventilation system, a water treatment plan, an escape hatch, an alarm system and the top of the launch area that has two doors weighing 70 tons each. In 1962, the space was commissioned for use, where five men lived on the grounds in the silo and the nearby support centers, with one rotating inside the silo at a time for their 48-hour shift until the site’s closing in 1965. “It will be here for 2,000 years, probably.” “It’s epoxy concrete and 600 tons of rebar,” he said. Louis to Chicago. The construction site resembled an open pit mine. The government built the silo in about a year in 1960, using enough concrete to build a 12-foot-wide road from St. The first level of the space housed the staff while they were on their shift, including bedrooms, bathrooms with a shower, a kitchen, and a recreational area, while the second floor held all the controls. The doors protected the people inside the facility from blasts and any potential intruders. The hallway leading to the underground area was built in a zigzag pattern so that in the event of an attack, the blast would force the front door into a wall instead of hitting the people and technology inside.īefore the actual control center are two 7,000-pound doors that open to the steps leading into the launch control center. “Just like the electricity, we didn’t get too extensive because they’re not going to keep it this way.” Living deep underground “The thing is, people here are going to build it the way they want,” he said. Novitzke also emphasized their goal for the project was to get every part to be a blank slate and usable for whoever comes in next. In the summer, the highest temperature it reaches is 72. The temperature helped, as the coldest it ever got was around 60 degrees. ![]() He said the underground space weathered well over time. Novitzke also set up power and drinkable water.

TapRooT® Root Cause Analysis is taught globally to help industries avoid them. Major disasters like this are often wake-up calls for how important it is to ensure that they never happen again. To learn more about the DeBruce Grain Explosion click here. Most of the silos in the north array were destroyed by the explosion along with the 21-story head-house. The southern gallery wasn’t nearly as damaged as the northern gallery because a dust clean up had recently been completed. As the blast waves passed beneath the northern silos the blast rose through the silos and popped most of the silos tops off due to the intensity of the blast. Once it reached the head-house the blast and fire blew upwards through the head-house and into the southern and northern galleries. The explosion utilized a crossover tunnel allowing it to spread in both directions of the two tunnels in the south array. This initial ignition set of a series of explosion through out the facility begin in the the Eastern tunnel of the south array silos. This is well beyond the 220 degrees Celsius need to ignite layered grain dust. All the friction caused by the moving belt heated the roller to a scorching temperature of 260 degrees Celsius. The non-lubricated bearing seized causing the the roller to lock into place, while the conveyor belt continued to move over the locked roller. The ignition source was a concentrator roller bearing that hadn’t be properly lubricated. The initial explosion, that set off a series of additional explosions, occurred when grain dust ignited in the Eastern tunnel under the South array of silos. How does a major explosion like this occur? The explosion killed 7 people, injured 10, and destroyed a large portion of the DeBruce Grain facility. On Ja grain elevator explosion occurred at DeBruce Grain located in Haysville, Kansas. Septem| Anne Roberts Remembering An Accident: DeBruce Grain
