MSHA releases report on fall fatality
The Mine Safety and Health Administration (MSHA) has released the investigation report on an Oct. 17, 2013, fatality at a cement plant involving a 52-year-old journeyman electrician with 5 years of experience who was killed after he fell approximately 6 feet from a step ladder, striking his head on the concrete floor, after a cable tray detached from the wall and struck the ladder.
He died in a hospital on Oct. 18 as a result of his injuries. MSHA notes the victim was wearing a hard hat at the time of the accident.
According to the investigation report, MSHA identified two root causes of the accident.
MSHA identified the first root cause to be that “[m]anagement did not ensure that the cable tray was secured to the wall of the MCC building when it was installed.”
Following the fatality, operation management implemented the following corrective action: “The cable tray has been removed from the MCC building.”
MSHA identified the second root cause to be that “[t]he step ladder was positioned parallel to the building and the victim was working perpendicular to the ladder, placing his body at an angle to the ladder while performing the work.”
Following the fatality, operation management implemented the following corrective action: “All persons were re-trained regarding ladder safety.”
MSHA issued and one order and two citations to the operation following the accident.
The order was issued on Oct. 17 under the provisions of Section 103(j) of the Mine Act “to prevent the destruction of any evidence which would assist investigating the cause or causes of the accident.”
The first citation was issued under the provisions of Section 104(a) of the Mine Act for a violation of 30 CFR 56.11001. MSHA notes: “The ladder was positioned parallel with the building and the victim was working perpendicular to the ladder, placing his body at an angle to the ladder while performing the work.”
The second citation was issued under the provisions of Section 104(a) of the Mine Act for a violation of 30 CFR 56.14100(b). MSHA notes: “The cable tray was supported by two brackets that were installed using two self-tapping screws in each bracket. The top screws were driven into the 22 gauge sheet metal, but not driven into structural steel. The bottom screws had been driven into the sheet metal and had contacted the steel support beam, but the holes became enlarged, allowing the screws to pull away from the wall.”
