An estimated 5 million workers are required to wear respirators in 1.3 million workplaces throughout the United States. Respirators protect workers against insufficient oxygen environments, harmful dusts, fogs, smokes, mists, gases, vapors, and sprays. These hazards may cause cancer, lung impairment, diseases, or death. Compliance with the OSHA Respiratory Protection Standard could avert hundreds of deaths and thousands of illnesses annually. This course introduces the student to OSHA requirements and effective respiratory program management.

Frequently Asked Questions (FAQs)


Course Introduction

H.G. Wells

In H.G. Wells’ classic novel, The War of the Worlds, invading Martians wreak havoc among helpless humans until a common form of bacteria does them in. Most likely, the bacteria was in the air along with gases, smoke, and dust raised along the Martians’ path of destruction.

During a normal day, the air we breathe is mostly oxygen and nitrogen — although it still contains trace amounts of harmful gases, smoke, vapors, and dust produced by us and Mother Nature. Fortunately, our lungs have a series of mechanical and biological barriers that keep such contaminants from harming us. But healthy lungs aren’t invincible. With repeated overexposure to toxins, these protective barriers break down, resulting in irritation, discomfort, or disease. Unfortunately, we may not even be aware of the damage until it’s too late to recover.

Breathing in the Workplace

Black lung, farmer’s lung, asbestosis, silicosis — You’ve probably heard of these work-related respiratory diseases and know of their consequences. These are just a few of the medical conditions that result when workers breathe contaminated air. However, protecting workers can be difficult because:

  • there are so many types of contaminants; and
  • there is no single method for controlling them in all workplaces.

If you’re a business owner or manager who wants basic information about protecting your employees from respiratory hazards, this course will get you started. The course summarizes respiratory hazards, how to evaluate the hazards, and how to control them. And, it describes what employers should know before their employees use respirators.

You’ll learn about the basic types of respirators and what you need to do to develop an effective respiratory protection program – the essential requirement of OSHA’s respiratory protection standard, 1910.134. This standard specifies what you must do to ensure that your employees use respirators safely and responsibly.

Course 756 Final Exam

OSHAcademy course final exams are designed to help ensure students demonstrate a sufficient understanding of the content covered within each course. To help demonstrate this understanding, students must achieve a minimum score of 70% on final exams. It is OSHAcademy's policy to protect the integrity of our exams and, as a result, we do not provide missed questions to students.

After you have studied all of the course material and taken the module quizzes, you can take the final exam. The module quizzes are optional, but we highly recommend you take each quiz, as the questions are similar to those on the final exam.

This is an open book exam. As you are taking the exam, if you find a question you are unsure of, you should use the course study guide or course web pages to research the correct answer. Don't worry if you fail the exam. You can study and retake the exam when you are ready.
