Sicherheitsaspekte / safety aspects
Wasserstoff ist: / Hydrogen is:
nicht detonativ im Freien / does not detonate in open air
nicht zerfallsf�hig / does not decompose
nicht selbstentz�ndlich / does not self-ignite
nicht oxidierend, nicht brandf�rdernd / non-oxidizing
nicht giftig / non-toxic
nicht korrosiv / non-corrosive
nicht radioaktiv / non-radioactive
nicht �belriechend / does not have an unpleasant smell
nicht ansteckend / non-contagious
nicht wassergef�hrdend / not harmful to water
nicht fruchtsch�digend / not harmful to the foetus (non-teratogenic)
nicht krebserzeugend / does not cause cancer (non-carcinogenic)
Wasserstoff ist leichter als Luft und entweicht schnell nach oben.
Hydrogen is lighter than air and vanishes rapidly upwards.
Wasserstoff hat einen hohen Diffusionskoeffizienten (vier Mal gr��er als Methan) und verd�nnt sich rasch in Luft. Hydrogen has a high diffusion coefficient (four times that of methane) and dilutes rapidly in air.
Wasserstoff hat deutlich engere Detonations- als Explosionsgrenzen � bei fr�her Z�ndung brennt er, bevor die Detonationsgrenzen erreicht werden. Hydrogen has significantly narrower detonation limits in air than explosion limits � when ignited early, it burns before detonation limits are reached.
Wasserstoff brennt mit unsichtbarer Flamme, die sehr wenig W�rme abstrahlt. Hydrogen burns with an invisible flame with very little heat radiated from the flame.
Wasserstoff ist farb- und geruchlos. Hydrogen is colorless and odorless.
