Frequently Asked Questions (FAQs)


This course describes the hazards of electrical work and basic approaches to working safely. You will learn skills to help you recognize, evaluate, and control electrical hazards. This information will prepare you for additional safety training such as hands-on exercises and more detailed reviews of regulations for electrical work.

Your employer, co-workers, and community will depend on your expertise. Start your career off right by learning electrical safe practices and developing good safety habits while working with electricity. Safety is a very important part of any job. Do it right from the start.

The course will present many topics. There are four main types of electrical injuries: electrocution (death due to electrical shock), electrical shock, burns, and falls. The dangers of electricity, electrical shock, and the resulting injuries will be discussed. The various electrical hazards will be described. You will learn about the 3-STEP Electrical Safety Model, an important tool for recognizing, evaluating, and controlling hazards. Practices that will help keep you safe and free of injury are emphasized. To give you an idea of the hazards caused by electricity, case studies about real-life deaths will be described.

Course 615 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. However, exam scores, certificates, and transcripts are provided only if you purchase a certificate package to document your training. If you do not require official training documentation, we will archive your exam results should you decide to purchase official certificates later.
