Frequently Asked Questions (FAQs)


Ergonomics is all about designing work to help ensure the health of the worker.

There are many types of musculoskeletal disorders (MSDs), including back pain, carpal tunnel syndrome, tendinitis, rotator cuff syndrome, sprains, and strains. These illnesses and injuries affect 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 for 34 percent of all lost-workday injuries and illnesses.
  • Employers report nearly 600,000 MSDs requiring time away from work every year.
  • MSDs account for $1 of every $3 spent for workers' compensation.
  • 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.
  • On average, it takes workers 28 days to recover from carpal tunnel syndrome, longer than the time needed to recover from amputation or fractures.
  • Workers with severe injuries can face permanent disability that prevents them from returning to their jobs or handling simple, everyday tasks.

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.

Course 152 Final Exam

Exam score sheet

After studying the course material and answering the quiz questions, it is time to take the final exam. We highly recommend answering the module quiz questions to check your understanding of the course material. The final exam questions are typically developed from these quiz questions.

OSHAcademy course final exams are designed to make sure students have gained a sufficient understanding of the content covered within each course. To help demonstrate this understanding, students must achieve a passing score on course final exams. It is OSHAcademy's policy to protect the integrity of our exams: as a result, we do not provide missed questions to students.

This is an open book exam. Students are permitted to use a separate browser window to review course content while taking the exam. If you do not pass a final exam, you will see a "Retake Exam" button next to the course on your student dashboard.

If you have already paid for your certificate

If you have already paid for certificates, your exam score will be displayed on your student dashboard after successfully passing the final exam. If you chose PDF certificates, you can view and print your certificate and personal transcript from your student dashboard. If you chose original printed documents, they will be prepared and mailed to the address in your student account.

If you only want free training

OSHAcademy provides free access to all training materials, including course modules, practice quizzes, exercises, and final exams.
