Our Level 2 content covers the basic knowledge presented in Level 1: O2 Aware and adds a deeper understanding of materials compatibility, factors contributing to ignition, and extensive good practices related to operating or maintaining oxygen systems.

WHA’s Level 2: O2 Practice course is intended for those that directly handle oxygen or oxygen-clean equipment and piping. If your job involves any form of operating or performing maintenance on oxygen systems, this course is for you. The content applies to a wide range of job descriptions and that is why this is WHA’s most popular oxygen safety training course.


The Level 2: O2 Practice course focuses on issues of oxygen fire safety as related to operation and maintenance of oxygen systems, wherever oxygen is used. A student will learn all of the Level 1: O2 Aware course content and will also have knowledge of the “why behind the what” related to materials compatibility, most common ignition mechanisms and safe practices to minimize the risk of oxygen fires.


  • As onsite training, our O2 Practices course offers content that is custom-tailored to a company’s specific oxygen systems and training needs. Onsite courses can range from ½-day to a full day depending on specific modules and content.
  • As eTraining, this course runs approximately 3-4 hours and is divided into six fully-narrated modules that can be presented to a group in a single session or taken individually with self-paced access of up to 30 days.


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.


Individuals involved in the use, specification, procurement, assembly, operation, maintenance, instrumentation, safety, management or incident investigation of systems, components and fires involving liquid or gaseous oxygen or oxygen-enriched gas mixtures.


Cost for level 2 training is typically $245-$600 per person. Final cost depends on several factors such as format, number of courses, number of personnel to be trained, and any custom add-ons. Group discounts and eTraining subscription discounts are available.
