Bruce W. Kirk, crusher operator, age 46, was fatally injured about 3:30 p.m., on November 12, 1997, when he was drawn into the tail pulley of a conveyor belt. Kirk had a total of 2 years mining experience working for this employer on a part-time basis. He had not received training in accordance with 30 CFR Part 48.
MSHA learned of the accident through a newspaper article on the morning of November 13, 1997. An investigation was started the same day.
The Peryea Pit, a sand and gravel operation, owned and operated by Michael Peryea Paving & Trucking, was located near Beekmantown, Clinton County, New York. The principal operating official was Michael Peryea, owner. The mine was operated intermittently as material was needed. The month preceding the accident, the mine had operated a single 8-hour shift for 5 days. Normally 2 persons were employed. However, on the day of the accident, 4 persons were on-site the victim and 3 contractor employees.
Sand and gravel was extracted from a single bench and transported to the plant by a front-end loader and backhoe where it was crushed and sized. The finished product was used as aggregate in the operator's construction business. On the day of the accident, however, Thomas Peryea, brother of Michael Peryea, was using an over-the-road haul truck to transport gravelly material from a trailer park site he was developing to the plant for processing. The processed material was then transported back to the site for use as roadway fill.
The last regular inspection of this operation was conducted on June 1, 1990. An attempted inspection was conducted on September 4, 1991. At that time, there was no activity at the pit and Michael Peryea, owner, stated that he was closed and no longer operating. Peryea resumed operation in the spring of 1995 without notifying MSHA pursuant to 30 CFR 56.1000.
PHYSICAL FACTORS INVOLVED
The crushing/screening plant, where the accident occurred, was originally a portable Austin-Western, 10-inch-by-40-inch jaw crusher. It had been modified by removing the wheels and installing a sizing screen and conveyor belts. A GMC Detroit, Model 471, 150-horsepower, diesel engine powered the plant.
Material to be processed was dumped into the primary hopper and discharged onto a conveyor belt that fed it to a sizing screen. Screened material fell into the discharge hopper, while oversized material fell into the crusher. A chute at the bottom of the discharge hopper deposited the screened material onto a 12-foot long, 30-inch wide conveyor belt that transported it to a stockpile. The victim became caught in the tail pulley of this belt.
The tail pulley was smooth and measured 34 inches long and 10 inches in diameter. It was driven by the diesel engine powering the plant through a chain and sprocket. The tail pulley was located at ground level, approximately 3 feet behind the chute below the discharge hopper. There were no guards on either side of the pulley to prevent persons from contacting the pinch points. At the time of the investigation, the discharge hopper and chute were full of partially frozen material.
A steel pipe, measuring 4 feet long and 1 inch in diameter, was found on the work platform adjacent to the screen. Reportedly, it had been used to dislodge material that hung up in the discharge hopper and chute. A steel jack handle and a package of cigarettes were found on the conveyor belt immediately in front of the tail pulley.
The plant had broke down several days prior to the accident. Reportedly, Thomas Peryea had discussed repairing the plant with his brother, Michael who was out of town on the day of the accident.
The weather conditions at the time of the accident were approximately 32�F, with light snow.
DESCRIPTION OF THE ACCIDENT
On the day of the accident, Thomas Peryea (owner of Peryea Construction) and Louis Williams, one of his employees, arrived at the mine at about 8:30 a.m. The two men began to repair the hopper, chain drive, and conveyor belt. Bruce Kirk (victim) arrived at about 9:30 a.m., while repairs were in progress. He told Thomas Peryea that the crusher also needed repaired, and then left the property about 11:00 a.m. for a job interview. Peryea and Williams completed the repairs and then stopped for lunch at about noon.
After lunch, Peryea and Williams were joined by Gordon Harvey, front-end loader operator. Harvey fed the plant while Peryea ran the crusher and Williams hauled material from the plant to Thomas Peryea's construction site. The plant was operated until about 2:30 p.m. when the discharge hopper and chute became plugged with wet material.
At about 2:30 p.m., Kirk returned to the plant from his job interview while Peryea was attempting to unplug the hopper and chute. Kirk reportedly shut down the plant and showed Peryea how to dislodge the wet material. Peryea stood on the work platform adjacent to the screen and used the steel pipe to knock down the material hung up in the hopper. At the same time, Kirk went to the chute below the hopper and used the jack handle to dislodge the material in it.
Once the material was flowing again, Peryea left the property while Kirk continued to operate the plant. At about 3:20 p.m., the hopper and chute plugged again. Kirk reportedly reduced the diesel engine speed to idle, which allowed the drive belts, chain, and conveyor belts to rotate slowly. He told Harvey that the hopper and chute had plugged again and that they should discontinue crushing because it would be dark before they could get it unplugged. Kirk then went to the opposite side of the plant where he could access the chute below the discharge hopper.
Harvey was about to leave the property but decided to ask Kirk if he would be needed the following day. As he approached the side of the plant where Kirk was working, he saw Kirk in a kneeling position caught in the pinch point between the conveyor belt and the tail pulley. Harvey motioned for Williams, who was operating the backhoe, to shut off the plant engine. Williams then went over and checked Kirk for vital signs. Finding none, Williams left the property to find a telephone to call for help.
The local rescue squad arrived about 4:00 p.m. and disassembled the tail pulley to extract Kirk. He was pronounced dead at the scene by the local coroner at 5:30 p.m.
The cause of the accident was failure to shut off the plant before performing work on the chute. Failure to guard the tail pulley was a contributing factor.
