Ergonomic Solutions for Electrical Contractors

The risk of shock isn’t the only occupational hazard that electrical contractors face on a daily basis. Like many construction trades, electrical work is full of ergonomic hazards that can cause serious injuries. Spools of wire, bundles of conduit, and tools themselves can cause significant stress on muscles when workers try to lift them. In fact, the Occupational Safety and Health Administration has called lifting heavy items “one of the leading causes of injury in the workplace.” Two factors typically play into a musculoskeletal disorder caused by working in the electrical industry: overexertion and cumulative tissue damage. Avoid both risk factors with these simple ergonomic tips: Use a forklift to lift and transport the heaviest materials on the job. These…more

TT-968: Re-Tensioning Lift Chains

Models Affected: All multi-level, Operator Aboard Battery Extractors Lift chains on multi-level Battery Extractors (BE) will require occasional re-tensioning. This Tech Tip will describe the easiest way to complete this task. Description: The lift chains on multi-level BE units must be properly tensioned in order to insure proper lifting of the inner carriage. If the chains are not equally tensioned, the cylinders may not lift simultaneously which can lead to repeated issues with the equalization chains. The equalization chains can skip links causing the carriage to lift out of level which can result in damage to the extractor frame and components. Recommendation: The proper tension for the lift chains is to have each cylinder pre-loaded. The chains should be tightened…more

The Ergonomics Sandbox: A New Way to Prevent Musculoskeletal Injuries in the Workplace

In 2013, a major tire manufacturer was facing a familiar problem. Too many employees were being injured on the job. This wasn’t a case of faulty processes or malfunctioning equipment. The simple fact was that staff members were working in conditions that made certain injuries inevitable. The plant in question hadn’t yet enacted ergonomics reforms, and the nature of the job involved working with large, heavy, and awkward structures. Every time a worker lifted an object, they increased the risk of developing a musculoskeletal disorder. Toward the end of 2013, safety officers at a plant in Fayetteville, North Carolina instituted a new ergonomics drive. The “Push, Pull, Lift” campaign was designed just to train workers on safe techniques for common…more
