- 4. • Musculoskeletal disorders (or MSDs) affect the muscles, nerves, tendons, ligaments, joints, and spinal discs, and are commonly caused by repetitive forceful exertions, reaching, and awkward positions. • OSHA reports MSDs are the single largest occupational safety and health problem in the U.S., a third of all lost workday cases, causing 1.8 million injuries each year. • The use of ergonomic solutions in the workplace, OSHA states, would reduce claims by 250,000 each year, saving companies millions in workers compensation, lost productivity, rehiring, retraining, and overtime. MSDs: A Common Overuse Injury Importance of Safety Training
- 5. • Symptoms of MSDs, including pain, numbness and tingling, develop gradually over time, showing up intermittently at first and then becoming more severe with prolonged or repeated use, eventually interfering with the ability to use a tool. • Repetitive use in work-related environments is especially threatening because overexerted tissues cannot adequately rest and recover, and instead will become inflamed. • With eventual continuous pain comes reduced worker productivity, lost time from work, temporary or permanent disability, and increased workers compensation costs.
