O2 Aware - Level 1 - Hazards Awareness

The learning goal of this course is to create awareness of the oxygen hazard and introduce safe, risk-mitigating practices.

The student will examine how oxygen increases the flammability and ignitability of materials, will discover how to apply a simple risk management mode, and recognize good practices that safely defend against the hazards.



The learning goal of this course is to study industry best practices and incorporate them into daily oxygen system handling, operation and maintenance.

The student will examine the hazards of oxygen use, recognize compatible materials, identify common ignition mechanisms in oxygen systems, and describe industry best practices related to oxygen handling, system cleaning, inspection, assembly, operations and maintenance.


The learning goal of this course is to explain the fundamental principles required to effectively design safe oxygen systems.

The student will understand the oxygen fire hazard, examine our risk management approach, compare materials compatibility, and identify ignition mechanisms in order to apply proven design methodologies and oxygen cleaning strategies that mitigate fire risk. Students will begin to analyze oxygen fire risk by outlining WHA's Oxygen Hazards & Fire Risk Analysis (OHFRA) method.


The learning goal of this course, accomplished through case study review, is to apply the OHFRA method.

The student will identify system-level and component-level hazards, will apply the Oxygen Hazards & Fire Risk Analysis tool, and will develop solutions, including some advanced design concepts, that lower both the probability and consequence of ignition through industry-specific case studies.



The learning goal of this course is to identify the hazards of contaminants in oxygen systems and apply industry best practices related to visual inspection.

The student will identify the oxygen hazard, with an emphasis on specific hazards related to contaminants. Students will practice using visual inspection tools, including white light, black (UV) light, and wipe tests to detect contaminants in oxygen piping, components, and equipment.



The learning goal of this course is to explain the why’s and how’s of oxygen cleaning.

The student will understand the oxygen hazard and risk management approach, will begin to recognize contaminant types and their respective hazards, and will study and apply WHA's oxygen clean philosophy, emphasizing four major areas: Start Clean (cleaning levels and methods), Verify Clean (visual inspection techniques), Assemble Clean (good practices for system assembly), and Maintain Clean (good practices for system maintenance).

Popular On-Site Courses

When our instructors travel to give courses, we often combine classes during our onsite stay to maximize the learning provided by your company in a brief period of time. Depending on your business' learning goals, we can teach to a variety of audiences in one stay. Clients have repeatedly requested certain combinations as well as repetitions of multiple sessions when you have a large staff to train.

Safety principles for oxygen and hydrogen are at the heart of what we teach. Click here to read more about our training and core content.

Course Levels

We have organized our courses by levels to help you choose the duration and mastery appropriate to your situation. To read more about the four levels, along with the intended audience, mastery and duration, please click here.

Students will not need to satisfy any prerequisites to any course level. All courses are self-contained units geared towards accomplishing the mastery indicated.

Credits and Certificates

WHA awards certificates that indicate quantities of learning credits, usually needed for proof of continuing employee development and learning. We offer Continuing Education Credits (CEUs), which have widespread acceptance, as well as Professional Development Hours (PDHs) for an engineer's continuing education needs. These credits are based on IACET's definition of contact hours. We typically provide both CEUs and PDHs on all our certificate-earning courses.
