Frequently Asked Questions (FAQs)




Stairways and ladders are a major source of injuries and fatalities among workers.

According to the Bureau of Labor and Statistics (2012), 14 percent of all work-related deaths are due to falls, with 20 percent of these deaths being related to the use of ladders.>

The Occupational Safety and Health Administration (OSHA) estimates there are more than 24,000 injuries and as many as 36 fatalities per year due to falls from stairways and ladders used in construction. Nearly half of these fall-related injuries are serious enough to require time off the job.

These statistics are a sobering reminder of the dangers faced when working on or around ladders and stairways. More importantly, most, if not all, of these injuries and deaths could have been prevented.

This course is designed to provide both employers and employees with the knowledge needed to work safely on stairways and ladders.

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.
