Sicherheitsaspekte / safety aspects
  
       
   
Wasserstoff ist: / Hydrogen is:
  
       
nicht detonativ im Freien / does not detonate in open air
  
   
nicht zerfallsfähig / does not decompose
  
   
nicht selbstentzündlich / does not self-ignite
  
   
nicht oxidierend, nicht brandfördernd / non-oxidizing
  
   
nicht giftig / non-toxic
  
   
nicht korrosiv / non-corrosive
  
   
nicht radioaktiv / non-radioactive
  
   
nicht übelriechend / does not have an unpleasant smell
  
   
nicht ansteckend / non-contagious
  
   
nicht wassergefährdend / not harmful to water
  
   
nicht fruchtschädigend / 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 größer als Methan) und verdünnt 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 früher Zündung 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 Wärme 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.
