On June 14, 2014, Kevin Lee Ames, Laborer, age 35, was killed at Chalk Hills Quarry, a gypsum facility. He was involved in the shipping process of the plant’s operation under the supervision of John Smith, Shift Supervisor. The shipping process involved operating a bagger unit, palletizer, propane shrink wrapper, and forklift. Just prior to the accident, Smith left the immediate area where Ames was working to complete his regular check on the mills. When Smith returned, he found that the victim had sustained serious burns to his left arm and chest. Ames was transported to a hospital for treatment. The victim died on July 28, 2014 from mucormycosis (fungal infection) due to the burns.
On September 30, 2014, the Mine Safety and Health Administration (MSHA) referred the accident to the Chargeability Review Committee. On April 9, 2015, the Chargeability Review Committee determined that this death should be charged to the mining industry. The death certificate indicated that the manner of death was accidental and that the cause of death was mucormycosis due to burns. An autopsy was not performed. At the time of the accident, Ames was being treated for a seizure disorder.
Chalk Hills Quarry, a surface, gypsum mine owned and operated by Diamond K Gypsum Inc., is located near Emery, Emery County, Utah. The principal operating official is Karen Palmer, President. Kris Allred, General Manager, is the person in charge of health and safety at the mine. The mine operates one 8-hour shift per day, five days per week. Total employment is 23 persons.
Gypsum is mined in an open pit quarry. Bulk ore is transported via bulk trucks to a sizing mill. Bulk gypsum is loaded in 50-pound bags and palletized using a fully automated bagger and palletizer. Loaded pallets are discharged to a runway where they are wrapped with plastic. A propane torch is used to shrink-wrap the plastic around the pallets in preparation for shipment.
The Mine Safety and Health Administration (MSHA) completed the last regular inspection at this operation on April 16, 2014.
DESCRIPTION OF ACCIDENT
On June 14, 2014, Kevin Lee Ames (victim) arrived at the mine at about 6:00 a.m. John Smith, Shift Supervisor, and the victim conducted workplace examinations until approximately 6:30 a.m., when they started working at the palletizer and bagger unit. They were shrink-wrapping the shipping pallets, which were loaded with stacked 50-pound bulk product bags, with heat from a propane torch.
At 1:00 p.m., Ames and Smith took a break for lunch. At 2:00 p.m., they resumed work on the palletizer. Smith left the area to make his normal checks on the mills. When Smith returned approximately 15 minutes later, he found Ames struggling to stand. Smith observed that Ames had sustained significant burns to his left arm and left side of his torso and was in a state of confusion and shock. The propane torch that Ames had been using was still on. Smith shut off the propane torch, dialed 911, and attended to the victim. At 2:27 p.m., Emergency Medical Services arrived, began treatment, and transported Ames to a local hospital.
Ames was transferred to a burn unit for advanced treatment where he died on July 28, 2014. The cause of death was attributed to mucormycosis as a result of burns.
