| | 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. |
