A 37-year-old heavy equipment operator/farm laborer died
when he unintentionally caused a backhoe’s boom to move, crushing him between
the boom and a stabilizer.
The victim had worked at a hay farm for two seasons
operating heavy equipment and providing other labor as needed. He had 20 years’
experience operating heavy equipment.
The employer had provided on-the-job training to the victim
to ensure that he understood how to safely operate the equipment he was
assigned to operate.
On the day of the incident, the victim was assigned the task
of clearing a field of large rocks. Another worker had used a chisel plow to
till the field.
The victim was using a backhoe’s loader to scoop up the
rocks and carry them from the field. As he was doing this task, he noticed a
metal chisel which had broken off the plow lying on the ground.
He stopped the backhoe and set its brakes, but did not turn
off the engine. He got out of the cab and walked over to the curved three-foot
long, 50 lb. chisel and picked it up.
He then walked to the rear of the backhoe and while standing
between the raised boom and the raised stabilizer, he placed the chisel in the
cab. The chisel struck the right boom-swing foot pedal which activated the boom
causing it to move, pinning and crushing him between the boom and the
stabilizer.
Requirements
• The manufacturer’s instruction manual must be the source
of information for the safe operation and maintenance of field equipment.
See WAC 296-307-076(2).
• Develop a written accident prevention program tailored to
the needs of your agricultural operation and to the types of hazards involved.
See WAC 296-307-030(2).
• Provide employee safety education and training programs
which include information about agricultural equipment hazards and safe work
practices.
See WAC 296-307-018(6).
Recommendations
• Ensure that backhoe boom and swing lock pins are installed
when backhoe is not being used.
• Do not place objects in the cab which could accidentally
depress the boom foot pedal.
• Shut down the equipment’s engine and follow the
manufacturer’s recommended parking procedures before leaving the operator’s
station.
• To prevent unintentional activation of the backhoe boom,
manufacturers and regulators should consider requiring the use of foot pedal
guards or some other method to disable the control when not in use.
