Repetitive Sprain Injury Prevention
Repetitive strain injury (RSI) is the #1 cause of occupational disease in the U.S., costing billions of dollars each year in workers’ compensation, and HVAC mechanics and sheet metal workers are particularly susceptible. These types of injuries occur when the body is subjected to stresses caused by repetitive tasks, forceful exertions, vibrations, mechanical compression, or sustained awkward positions. Common RSIs include carpal tunnel syndrome, thoracic outlet syndrome, Raynaud’s syndrome, and trigger finger.
To prevent RSI, identify hazards in the workplace and take steps to correct them. Be aware of early symptoms such as pain or tingling in neck, shoulders, arms or hands. Break up prolonged repetitive movement with rest periods, or by rotating tasks. Stretch or move around if you experience any task-related discomfort. Use ergonomic tools specifically designed for the task at hand. Arrange layout of tools and equipment to minimize excessive stretching and bending, and practice proper lifting techniques. Cold can increase RSIs, especially those related to vibration, so wear gloves or use hand warmers whenever possible. Use ergonomic PPEs such as back supports, wrist and arm supports, and elbow and knee pads, vibration dampening gear, and boots with good ankle support.
