The main hazards associated with hydrogen systems can be listed and prioritized as follow (ISO/TR 15916:2015): flammability (thermal effects, pressure effects, easy ignitability of some mixtures), small size of the molecule (low viscosity, high diffusion rate, high buoyancy), asphyxiation hazards if oxygen is replaced.	cache/cet-15609.pdf	txt/cet-15609.txt
