Employees who work in confined spaces face increased risk of serious physical injury. Hazards involving a confined space include entrapment, engulfment, and dangerous atmospheric conditions. As a result, employees who conduct work within confined spaces must be properly trained.

This course presents information on the definition of a confined space, hazards of a permit-required confined space, and alternative procedures to control atmospheric hazards. The written program and entry permit system, rescue and emergency services, and importance of training are also discussed.

Frequently Asked Questions (FAQs)


Course Introduction

Many workplaces contain spaces that are considered to be "confined" because their configurations hinder the activities of employees who must enter into, work in or exit from them. In many instances, employees who work in confined spaces also face increased risk of exposure to serious physical injury from hazards such as entrapment, engulfment and hazardous atmospheric conditions. Confinement itself may pose entrapment hazards and work in confined spaces may keep employees closer to hazards such as machinery components than they would be otherwise. For example, confinement, limited access and restricted airflow can result in hazardous conditions that would not normally arise in an open workplace.

According to the Z117 ANSI Accredited Standards Committee (ASC) for Confined Spaces, a review of 200 confined space fatality cases from the U.S. Department of Labor (DOL) Occupational Safety and Health Administration (OSHA) database occurring between 1993 and 2004 confirmed that the distribution of causes had not changed to any significant degree. The committee also noted that approximately 65 percent of incidents with fatalities involved atmospheric contamination and engulfment accounted for less than 10 percent of the identified causes. (ASSE Mini Tech-Brief: Confined Spaces - 9/2009)

Keep in mind: Most permit-space accidents happen for the following reasons:

  • Workers have not been properly trained to recognize permit-space hazards.
  • Hazards are not eliminated or controlled before workers enter the space.
  • Rescuers are inexperienced or improperly trained.

Course Goals

This course has been developed to explain basic requirements detailed within OSHA Standard 29 CFR 1910.146, Permit-required Confined Spaces, which will assist employers in establishing and maintaining an effective confined space program. By implementing such a program, our employees will be able to:

  • Recognize, evaluate, and control confined space hazards.
  • Save lives and protect employees from job-related injuries and illnesses.
  • Promote safe and effective work practices.
  • Reduce preventable workers’ compensation costs.
  • Comply with company procedures and practices.

This course provides a general overview of a particular topic related to OSHA standards. It does not alter or determine compliance responsibilities in OSHA standards or the Occupational Safety and Health Act of 1970. Because interpretations and enforcement policy may change over time, you should consult current OSHA administrative interpretations and decisions by the Occupational Safety and Health Review Commission and the Courts for additional guidance on OSHA compliance requirements.

Course 713 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.
