Fire Hazards In Oxygen Systems

About the Course

In this two-day course you'll learn to identify and evaluate hazards in oxygen systems. You'll gain an understanding of safe practices in design, materials selection, and operation of oxygen systems, as well as related ASTM standards.

Learning Outcomes

By the end of this course you will:

• Recognize physical principles and empirical observations on which these safe practices are based
• Collect information needed to cope with fire hazards in oxygen systems
• Identify and locate relevant test data for analyzing the ignition and damage potential of oxygen systems
• Apply the concepts by working out selected exercises in class

Who Should Attend

Engineers, scientists, technicians, purchasing agents, plant managers and operators, and safety professionals involved in production or use of liquid or gaseous oxygen, or oxygen-enriched gas mixtures. Also, those who supply, design, or manufacture hardware for oxygen services.

Course Outline

Class begins each day at 8:00 AM and ends at 5:00 PM

About the Instructors

ELLIOT FORSYTH is a Senior Oxygen Safety and Forensic Engineer at WHA International, Inc. (WHA). For more than 20 years Elliot has been consulting with industry, military, and government clients worldwide on technical aspects oxygen safety, fire risk analysis, material compatibility, system and component design, oxygen cleaning, and forensic fire analysis. He also serves as WHA's Director of Technical Training where he develops and instructs custom-tailored oxygen safety training products for nearly all industries that use oxygen. Elliot is one of the co-developers of ASTM's oxygen safety courses and has been an active leader and developer of international standards on oxygen system design and safety throughout his career. He currently serves as Chair of ASTM Committee G04 on materials compatibility in oxygen-enriched atmospheres. Elliot also served with industry members on the task group that developed the latest CGA G-4.4 standard (harmonized with EIGA 13-12), which governs industry design and materials selection for oxygen pipeline systems and equipment.

About ASTM and Sponsoring Committee G04

Committee G04 on Compatibility and Sensitivity of Materials in Oxygen Enriched Atmospheres developed the standards used in this course. For more information, contact Kristy Straiton at 610-832-9640 or go to our G04 technical committee page.

Attention: Professional Engineers

If your state has a continuing education requirement for license renewal, ASTM training courses and ASTM membership can help you meet that requirement.

How Learning Will Be Assessed

Learning will be assessed through a series of question and answer sessions.
