Course Overview

Who Should take this course?

This Ethylene Oxide Awareness course provides a general awareness of the risks and the regulatory requirements for protecting employees who work with ethylene oxide, as required by OSHA.

Ethylene oxide (EtO) is used extensively by hospitals and other industries as a sterilizing agent. It is also used for making many consumer products as well as non-consumer chemicals and intermediates. EtO is a colorless, odorless gas, which is both flammable and highly reactive. You cannot smell EtO until it reaches levels that can cause serious harm to human health. Studies show that EtO can be hazardous to human health. Short-term exposures can cause respiratory irritation and lung injury, shortness of breath, headache, nausea, vomiting, and diarrhea. Long-term exposure may cause cancer, reproductive effects, genetic changes, and damage to the nervous system.



The objective of this Ethylene Oxide Awareness course is to provide a general awareness of the risks and the regulatory requirements for protecting employees who work with ethylene oxide, as required by OSHA.

The course will also introduce students to the Occupational Safety and Health Regulations for ethylene oxide, Subpart Z, Toxic and Hazardous Substances - 29 CFR 1910.1047

Learning Objectives

Upon completion of this course, the student will be able to:

  • Explain what ethylene oxide is;
  • Identify where workers may encounter ethylene oxide;
  • Describe hazards and health effects of ethylene oxide exposure;
  • Understand the essentials of OSHA’s ethylene oxide standard;
  • Identify and describe OSHA methods of compliance to prevent ethylene oxide exposure; and
  • Understand the requirements for medical surveillance and hazard communication.


This fully narrated course is built for success and includes interactions, exercises, and knowledge checks intended to prepare students for the final exam. Students must answer each knowledge check and complete each interaction in order to proceed.

Course Sections

This course consists of 1 module broken down into 3 sections. Students are required to take each section in sequential order as listed below.

Course Modules, Sections, and Exams
ModuleSection / Topic
Module 1
Section 1 - Course Overview
Section 2 - Introduction to Ethlyene Oxide in the Workplace
Section 3 - Limiting Exposure to Ethylene Oxide
Final Exam


This course has one final exam based upon the material in the 3 course sections.

The exam consists of 10 questions selected at random from a larger pool of questions. A score of 70% or better is required to pass each exam. Students who do not pass the exam the first time may retake it as many times as necessary in order to pass.

Training Requirements

Each employee covered by the Ethylene Oxide Standard must be trained to demonstrate knowledge and understanding of at least the following:

  • Methods and observations that may be used to detect the presence or release of ethylene oxide in the work area (such as monitoring conducted by the employer, continuous monitoring devices, etc.);
  • The physical and health hazards of ethylene oxide;
  • The measures employees can take to protect themselves from hazards associated with ethylene oxide exposure, including specific procedures the employer has implemented to protect employees from exposure to ethylene oxide, such as work practices, emergency procedures, and personal protective equipment to be used; and
  • The details of the hazard communication program developed by the employer, including an explanation of the labeling system and how employees can obtain and use the appropriate hazard information.

Additionally, workers must receive training, when required by OSHA standards, on the specific hazards of their job. Training providers should be used to ensure credibility and augment a company’s training program. Therefore, in addition to the training provided by an outside party, a student should receive site-specific training supplied by their employer. This training should target the company’s unique approach to hazard prevention, including the use of site-specific equipment, health and safety policies, and emergency procedures. As a rule, this company-specific training should be well documented.

Mobile Version


We're excited to announce that this course is now available in HTML 5, making it more compatible with the browser on your mobile device (e.g., smartphone or tablet). This course requires only the most recent version of your mobile device's web browser.

Tablet Pros and Cons

Mobile versions of this sort of training are new, but below are some Pros and Cons that we have noticed during our extensive testing.


  • No computer needed
  • Tablet mobility
  • Tablet screen graphics


  • Smartphone screens can be too small to see
  • Mobile browsers react differently than computer browsers
  • Phone calls can interrupt training

During our testing we really noticed that tablets work much better than smartphones, simply due to their screen size.

Growing Pains

Because this is a Beta Version of our course, you may encounter some issues as we work out the kinks.

Your Mobile Browser

While HTML5 makes taking this course on mobile devices possible, not all mobile browsers are optimized for HTML5, meaning you may not have complete functionality. If you have difficulty taking this course using the browser on your mobile device, you may need to use a different browser.

Test the functionality of your browser using HTML5 and compare it to the performance of other browsers. If you find other browsers are more compatible than your own, you may want to make the switch.
