On August 25, 2014, Glenn F. Dibble, Truck Driver, age 54, was killed when he fell approximately 8 feet from loaded stacked pallets. He was attempting to retrieve wooden planks from the rafters in a bag storage building.
The accident occurred due to management’s failure to establish and implement procedures for persons to safely access materials stored in the bag storage building. Additionally, Dibble did not receive task training addressing safe work procedures for accessing overhead areas and the potential hazards associated with the task.
Gardenscape of New York, a surface crushed limestone operation owned and operated by Gardenscape of New York, is located in Gouverneur, St. Lawrence County, New York. The principal operating officials are David G. Kasmoch, President, and Kevin Dibble, Plant Manager (victim’s cousin). The mine typically operates two 10 hour shifts, five days per week. Total employment is 20 persons. Most of the miners work on dayshift from 7:30 a.m. to 4:00 p.m. while a 3-person night shift works from 3:45 p.m. to 1:15 a.m.
Limestone is drilled and blasted from a multiple-bench quarry. A front-end loader is used to load a haul truck which transports the broken limestone to a primary feed hopper for processing. The primary crushing plant consists of a grizzly-type vibrating feeder and a jaw crusher with an under jaw discharge conveyor. The crushed material is conveyed to a scalping screen. The undersized material flows to a conveyor and the oversized material falls into a cone crusher at the secondary plant for additional crushing. When the material exits the secondary plant, it is conveyed to the mill for further reduction. The material is stored in bulk or dried for subsequent bagging. Finished products are sold as bulk or bagged agricultural lime.
The Mine Safety and Health Administration (MSHA) completed the last regular inspection at this mine on July 23, 2014.
DESCRIPTION OF ACCIDENT
On the day of the accident, Monday August 25, 2014, Glenn F. Dibble (G. Dibble, victim) reported for work at 7:30 a.m., his usual starting time. G. Dibble was instructed by Kevin Dibble (K. Dibble), Plant Manager, to haul five to six loads of sand from a nearby mine. During the morning, coworkers observed G. Dibble hauling several loads of material in an over-the-road dump truck.
At approximately 12:30 p.m., Murlyn Harris, Front-end Loader Operator, loaded G. Dibble’s truck with crusher run material to be delivered off site.
At about 2:00 p.m., the secondary crushing plant shut down with a full load of material in the cone crusher. The cone crusher needed to be emptied before the plant could be restarted. Derek Collier, Crusher Operator, Jeff Jenkins, Plant Operator/Shift Supervisor, and Harris decided to use chains and slings connected to a front-end loader in an attempt to lift the crusher and allow material to flow through.
At approximately 3:00 p.m., Harris observed G. Dibble return to the mine and park his dump truck. About 3:15 p.m., G. Dibble stopped by to assist with the work on the cone crusher. G. Dibble stated that they would need several wooden planks to prevent material from flowing from the stone hopper into the crusher. G. Dibble then stated that he knew where the planks were and left in a pickup truck and traveled toward the bag storage building.
At 3:45 p.m., the 3-person nightshift crew gathered in the breakroom, punched their timecards, and traveled to the milling plant. The crew consisted of two bagging machine operators and an operator/machine tender.
When the work on the cone crusher was completed, Collier, Jenkins, and Harris went to the breakroom to punch out for the shift. Harris noticed that G. Dibble had not returned and assumed that K. Dibble had sent him on some errands. The dayshift crew left the mine at 4:00 p.m.
On Tuesday, August 26, 2014, at 1:25 a.m., the nightshift crew returned to the breakroom at the end of the shift. At that time, they noticed that G. Dibble’s motorcycle helmet was on the table in the breakroom. Darren House, Bagger, looked outside and saw that G. Dibble’s motorcycle was parked behind the breakroom. Nicholas Trapp, Bagger, noticed that the pickup truck was not parked near the shop as it normally was during nightshift. At that time, Steven Spano, Operator/Machine Tender, checked G. Dibble’s timecard and noticed he had not punched out at the end of dayshift. According to interviews, they assumed G. Dibble’s motorcycle did not start and he had taken the pickup truck home. The nightshift crew left the mine at 1:45 a.m.
Harris arrived at the mine at 5:12 a.m. and waited in the breakroom for the rest of the dayshift crew to arrive. While waiting, he noticed G. Dibble’s motorcycle helmet was still on the table in the breakroom. At 6:00 a.m., Harris and Collier punched their time cards and decided to look for G. Dibble. They saw the pickup truck sitting near the bag storage building, went inside, and found G. Dibble lying between two loaded pallets. He was unresponsive and had no vital signs. They immediately called the local authorities and K. Dibble to report the accident. The New York State Police and the St. Lawrence County Coroner responded to the mine. At 7:30 a.m., the victim was pronounced dead at the scene by Kevin Crosby, St. Lawrence County Coroner. The cause of death was attributed to blunt force trauma.
INVESTIGATION OF THE ACCIDENT
MSHA was notified of the accident at 6:19 a.m. on August 26, 2014, by a telephone call from Derek Collier, Crusher Operator, to the National Call Center. The National Call Center notified Victor Lescznske, Supervisory Special Investigator, and an investigation was started the same day. An order was issued under provisions of Section 103(j) of the Mine Act. This order was later modified to Section 103(k) of the Mine Act after the arrival of an Authorized Representative at the mine site.
MSHA’s accident investigation team traveled to the mine, conducted a physical inspection of the accident scene, interviewed employees, and reviewed documents and work procedures relevant to the accident. MSHA conducted the investigation with the assistance of mine management, employees, and state law enforcement.
Location of the Accident
The accident occurred in the bag storage building on the east end of the mine. The structure is a three-sided enclosure built to store and shelter stacked pallets of new bags and other materials needed for the mine (see Figure 1). The earthen floor is covered with fine gravel and free of debris. Wire mesh bag support columns for the onsite dust collectors and wooden planks are stored in the building’s rafters approximately 12 feet from ground level.
On the day of the accident, weather conditions were clear with an average temperature of 80 degrees Fahrenheit and wind approximately 6 mph. Sunrise was at 6:18 a.m. The investigators determined that the weather conditions and lighting were not contributing factors in the accident.
The evidence gathered during the investigation indicated that the victim had climbed approximately 8 feet on top of two stacked pallets and reached for wooden planks in the rafters above him (see Figures 2 and 3). Each wooden plank was approximately 2 inches thick by 12-inches wide by 12 feet long and weighed 30 pounds. The victim had taken down two wooden planks before falling to the ground.
TRAINING AND EXPERIENCE
Glenn Dibble had 1½ years of mining experience as a truck driver, all at this mine. A representative of MSHA's Educational Field Services reviewed the mine operator’s Part 46 training records for G. Dibble. Although the records documented that G. Dibble had received all required training, including task training and annual refresher training, he did not receive task training addressing safe work procedures for accessing overhead areas and the potential hazards associated with the task.
ROOT CAUSE ANALYSIS
Root Cause: Management failed to provide a safe means of access for miners retrieving stored materials from the overhead rafters in the bag storage building.
Corrective Action: All materials were removed from the overhead rafters and stored in a safe manner. In addition, management established written policies and safe work procedures, including the use of ladders for any work being performed overhead. Miners were trained in the new policies and procedures.
Root Cause: Management failed to provide the victim, an over-the-road truck driver, sufficient task training addressing safe access and safe work procedures while performing additional duties at the mine.
Corrective Action: Management has revised their Part 46 training plan to include task training for over-the-road truckers who may perform additional duties at the mine. All truck drivers were trained in accordance with the revised plan.
The accident occurred due to management’s failure to establish and implement procedures for persons to safely access materials stored in the bag storage building. Additionally, G. Dibble did not receive task training addressing safe work procedures for accessing overhead areas and the potential hazards associated with the task.
