Texto original en inglés de la MSHA
Brendan P. DeMasters, a 40-year-old Contract Foreman, 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. Contract management did not take all necessary precautions to protect persons working with compressed air while cleaning out an obstruction in a vertical drill hole, including ensuring that personnel were safely positioned during the procedure.

Contract management did not ensure adequate procedures to protect persons working with compressed air while cleaning out an obstruction in a vertical drill hole, including positioning of personnel during this process.
Acción correctiva: The contractor developed a plan and procedures and then trained employees on the new plan with procedures for cleaning previously blasted vertical drill holes when an obstruction has been encountered. This plan addresses safe work procedures and where personnel are to be positioned during the various phases of drill hole cleaning process.
