152 Ergonomic Hazards in Construction
Skip to main content

Introduction

There are many types of musculoskeletal disorders (MSDs), including back pain, carpal tunnel syndrome, tendinitis, rotator cuff syndrome, sprains, and strains. They account over 30 percent of all lost-workday injuries and illnesses.

These illnesses and injuries effect one or more parts of the musculoskeletal system. They include sprains, strains, inflammation, degeneration, tears, pinched nerves or blood vessels, bone splintering and stress fractures.

Symptoms include discomfort, pain, fatigue, swelling, stiffness, or numbness and tingling.

The High Cost of MSDs

  • MSDs account over 30% of all workers' compensation costs.
  • MSDs each year account for more than $15 billion to $20 billion in workers' compensation costs. Total direct costs add up to as much as $50 billion annually.
  • It takes an average of 28 days to recover from carpal tunnel syndrome.

In this course, we'll look at practical ideas to help reduce the risk of repetitive stress injury in common construction tasks. While some solutions may need the involvement of the building owner or general contractor, there are also many ideas individual workers and supervisors can adopt.
