Article "How safe is Hydrogen?" by J. Hord: pp 615 Symposium Papers of the "Hydrogen for Energy Distribution" Lyon, France, July 24-28,1978!

Provide analyses and experimental data to determine vapor cloud dispersion characteristics (near-field and far-field) resulting fromlarge liquid spills.
Fires: Assess thermal radiation effects and the effects of water vaporabsorption.
Evaluate existing fire control techniques: dry chemicals, foams, etc.as found useful in controlling LNG fires.
Experimentally determine vaporization rates for large pools of liquidhydrogen (surface and material effects).
Correlate analytical studies with experimental studies to determineliquid spreading rates, resulting from large liquid spills.
Determine practical lower flammable limit for the propagation of openair explosions (8%+ H2-in-air?).
Experimentally verify detonation in open air detonable clouds.(Evaluate strong initiator and the possibility of transition fromdeflagration to detonation in theabsence of turbulence inducers).
