The primary safety hazards of hydrogen are fire (and the resulting burns since a hydrogen fire is not easily visible) and explosion if the hydrogen is compressed in a cylinder.
It is difficult to suffocate in hydrogen, although not impossible, because the gas is very light, rises to the ceiling, and easily exfiltrates through seams and small fissures in structures.
Hydrogen is highly combustible.
hydrogen sulfide is not hazardous
Not really.....
Hydrogen is released while charging.
It is hydrogen cynide , highly harmful and hazardous for life.

Yes it does. Hydrogen is lighter that air therefore it rises and floats.
Methane and Oxygen
If consumed rubidium may be poisonous, but other wise it isn't.
When hydrogen is mixed with sulfur, it can produce hydrogen sulfide (H₂S), a gas known for its characteristic smell of rotten eggs. This compound is highly toxic and can be found in natural sources such as volcanic gases and hot springs. Safety precautions are essential when handling hydrogen sulfide due to its hazardous nature.
Hydrogen bromide is typically purchased in compressed gas cylinders from specialty gas suppliers. However, due to its hazardous nature and regulatory restrictions, it may not be readily available for purchase by the general public. It is important to follow proper safety protocols and regulations when handling hydrogen bromide.
Dangerous in what way? hydrogen just being burned does not contribute to global warming, but what about 'making' the hydrogen? Does that use other fuels that contribute to global warming? Hydrogen is more explosive if that is what you mean by dangerous. Hydrocarbons burn to form carbon dioxide which contributes to global warming.
