This course provides a comprehensive technical review of the safety-related physical and combustion properties of hydrogen, with direct comparisons to natural gas systems. Based on expert instruction from Dr. Lennie Klebanoff, the course examines the scientific principles governing hydrogen behavior, including flammability, explosion dynamics, deflagration-to-detonation transition (DDT), fire radiation characteristics, material compatibility, embrittlement, permeability, diffusion, and open-air dispersion.

The course approaches hydrogen safety from a data-driven, engineering-focused perspective rather than through a generalized risk perception. Participants gain an understanding of how hydrogen behaves under various operational and accidental release conditions, why its physical properties differ fundamentally from conventional hydrocarbon fuels, and how modern engineering standards mitigate associated risks.

The course also explores practical hydrogen applications in transportation, maritime systems, aerospace, and industrial infrastructure while emphasizing the importance of material selection, ventilation, leak management, and facility design. Regulatory frameworks, particularly the National Fire Protection Association NFPA 2 Hydrogen Technologies Code, are integrated throughout the lessons to connect scientific principles with real-world safety practices.
