On March 24, 2010, a 63 year-old contract truck driver with 21 years of experience was fatally injured at a surface area of an underground salt mine. The victim was loading his truck under a 150 ton salt bin when it collapsed, falling onto the cab of the truck. A second victim working in the area received serious injuries.
- Routinely examine metal structures for indications of weakened structural soundness (corrosion, fatigue cracks, bent/buckling beams, braces or columns, loose/missing connectors, broken welds, etc.).
- Keep corrosive material spillage/build-up removed from metal structures.
- Report all areas where indications of structural weakness are found.
On September 23, 2009, a 38 year old contractor miner/driller with 10 years of experience was fatally injured while working at a shaft construction project. The victim and four other employees were located on the top deck of a 2-deck work platform that was suspended in the shaft. He was not wearing fall protection and fell through an opening in the center of the top deck of the work platform to the bottom of the shaft 38 feet below.
- Always wear, and use, suitable fall protection when positioned or working where fall hazards exist.
- Assure that fall protection systems for multiple workers allow for independent movement.
- Establish work procedures to eliminate creating openings through which persons may fall.
- Stop, Look, Analyze and Manage the hazards associated with each work task.
On November 23, 2009, a 37-year old contract mechanic with 4 years of mining experience was fatally injured at a shaft sinking operation. The victim and another miner were disassembling a two part sheave wheel from the end of a pivoting hoist. The hoist boom fell suddenly and struck both miners. The victim died the next morning from his injuries. The other miner was treated at a hospital.
- Securely block raised equipment to prevent accidental movement before working beneath such equipment.
- Routinely monitor work habits and strictly enforce compliance with established safe work procedures.
- Ensure that equipment operators communicate with other workers who work in close proximity to their equipment.
- Ensure that personnel are trained to recognize hazardous work procedures, including working under the boom of a crane.
- Discuss work procedures and identify all hazards associated with the work to be performed, along with the methods to protect personnel.
On February 19, 2009, a 61 year-old laborer with 12 years of experience was injured at a sand and gravel operation when he was struck by a crane’s falling boom. The crane was lifting a crusher and the victim was acting as a signalman when the accident occurred. He was hospitalized and died on April 12, 2009, as a result of his injuries.
- Prior to attempting a lift, know the weight of the load (including the load block and rigging) and make sure it is less than the crane’s lifting capacity for the required reach. Refer to applicable load charts.
- Perform a thorough pre-operational inspection of the crane and rigging components.
- Stay clear of a crane’s overhead boom and do not work beneath a suspended load.
- Always be certain that the object being lifted is completely detached from its supporting structure prior to attempting a lift.
- Insure that the crane turntable is level prior to lifting.
- Make sure the load is aligned directly beneath the centerline of the boom to prevent side loading.
- Confirm that the load will not exceed the allowable capacity of the rigging.
- Follow the crane manufacturer’s recommendations when making structural repairs and use certified welders.
