Frequently Asked Questions (FAQs)


Course Introduction

Conduct accident investigations with accident prevention in mind.

Workplace accidents occur each and every day all across the country. Each year the Bureau of Labor Statistics publishes a statistical summary of injuries and illnesses (See summary below) that emphasizes this fact.

The failure of people, equipment, supplies, or surroundings to behave or react as expected causes most of the accidents. Accident investigations determine how and why these failures occur. By using the information gained through an investigation, a similar or perhaps more disastrous accident may be prevented. Conduct accident investigations with accident prevention in mind. Investigations are NOT to place blame.

National Census of Fatal Occupational Injuries in 2015

The overall incidence rate of nonfatal occupational injury and illness cases requiring days away from work to recuperate was 104.0 cases per 10,000 full-time workers in 2015, down from 107.1 cases in 2014. In 2015, there were 1,153,490 days-away-from-work cases in private industry, state government, and local government - essentially unchanged from the number of cases reported in 2014. The median days away from work to recuperate - a key measure of severity of injuries and illnesses - was 8 days in 2015, 1 day fewer than reported in 2014.

The Challenge

The challenge to any accident investigator is to report the findings in a well-thought-out manner to ensure management will ultimately adopt recommendations for improving its safety management system, thus solving problems long-term. It's a common struggle trying to overcome long-held perceptions about safety and how accidents occur.

Course 702 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.
