Fatal Exploding Vessels under Pressure Accident Report

This accident report reviews the case of Brendan P. DeMasters, a 40-year-old Contract Foreman who died on October 2, 2018, while attempting to clean out a previously blasted, vertical drill hole with a high pressure compressed air line. While kneeling with his torso positioned over the hole, DeMasters tried to push the grout line through an obstruction approximately 30 feet down the hole. A sudden release of pressure propelled remnant stemming material from the hole, striking DeMasters in the chest.
