Hydrogen, Toxic Gas and Cryogenic Safety
Three fluid classes whose behaviour defeats intuition built on hydrocarbons
Hydrogen, toxic gases and cryogenic fluids each break assumptions that hold for ordinary hydrocarbons. This course covers hydrogen embrittlement and its near invisible flame, toxic release and exposure endpoints, and the cold embrittlement, oxygen enrichment and rapid phase transition risks of cryogenic service.
This course sits alongside our Process Safety Engineering consulting work, so what is taught is what we do.
Who should attend
Course content
Every module is taught with worked examples and exercises drawn from real plant, and adapted to your own process where the course runs in house.
Hydrogen
- Wide flammable range, very low ignition energy and buoyant dispersion
- A flame that is close to invisible in daylight and how detection accounts for it
- Embrittlement and material selection for hydrogen service
- High pressure storage, permeation and leak detection
- Deflagration to detonation transition in confined geometry
Toxic gases
- Acute toxicity, exposure endpoints and the difference between AEGL, ERPG and IDLH
- Dense toxic gas dispersion and the ground level hazard
- Scrubbing, containment and secondary enclosure
- Hydrogen fluoride behaviour and why it is treated separately
Cryogenic fluids
- Low temperature embrittlement and material selection
- Rapid phase transition and boiling liquid expanding vapour explosion
- Oxygen enrichment from condensing air and the fire risk it creates
- Cold burns, asphyxiation and confined space implications
Common engineering responses
- Detection selection for each fluid class
- Ventilation, layout and separation distances
- Emergency response considerations specific to each
What you receive
- Material selection guidance for hydrogen and cryogenic service
- A toxic exposure endpoint reference for common gases
- Detection and layout checklists by fluid class
- Assessment result and attendance record
What changes afterwards
- Hydrogen projects are engineered for hydrogen rather than for natural gas
- Toxic release planning uses the right endpoint for the decision being made
- Cryogenic installations account for embrittlement and oxygen enrichment
- Detection choices suit the fluid rather than the site standard
