It is NOT.
non-toxic, non-explosive, non-reactive, non-corrosive: almost completely INERT.
However, if you breath pure nitrogen gas you asphyxiate and die because there is no oxygen.
However, don't stick your fingers in liquid nitrogen, they'll be 'burned' at -190oC.
Liquid nitrogen is not poisonous, however, it can be dangerous if it comes into contact with skin or if it is inhaled because of its extremely low temperatures. It can cause severe burns or frostbite upon contact with skin and can displace oxygen in the air if inhaled in high concentrations.
Hydrogen gas itself is not poisonous, as it is a naturally occurring element and is non-toxic. However, hydrogen can be dangerous if it is in high concentrations in the air because it is highly flammable and can displace oxygen, leading to a potential risk of asphyxiation.
Pure nitrogen can be dangerous as it leads to quick asphyxiation without the human body noticing that anything is wrong. Because air is mostly nitrogren gas, breathing pure nitrogen feels like breathing air (unlike breathing air that has a high fraction of carbon dioxide for example or noxious gases with identifiable smells), which is why it can be dangerous. Several deaths due to nitrogen asphyxiation occur in the US every year as nitrogen is used widely, for example to pressurize instrumentation compartments to reduce fire hazard or in research laboratories. Accidental death occurs when servicing such compartments without first removing the nitrogen athmosphere (see 1981 space shuttle accident) or due to accidental spillage (i.e. leaking containers). Compounds and molecules of nitrogen that contain oxygen and other elements, however, can be dangerous, but many are not. Cyanide, for instance, is a molecule that contains both carbon (the building blocks of life) and nitrogen. On the other hand, nitrogen monoxide (a neurotransmitter) and nitrogen dioxide (laughing gas) are mostly nontoxic, but as with all chemicals and molecules, including water, this is a matter of relative scale.
Well technically if it was frozen then it would not be a liquid. The reason why liquid nitrogen is dangerous is because of its low temperatures. To have nitrogen which is normally a gas to become a liquid you must make the temperature extremely low. If you stick anything into this liquid nitrogen it will freeze it. This is because it is below the freezing point for most organic structures but now below the freezing point for nitrogen. For nitrogen to become a solid the temperatures must go even lower.
Good and Funny question. Nitrogen is all over the world. It occupies large proportion of air we inhale. If it was poisonous, all the livings would be dead! So, its NO ***************2nd Opinion ************* Not always so funny. At normal atmospheric pressure we don't get enough in our blood to affect us, but if we breathe air at high pressures, as scuba divers do, the amount of nitrogen in us goes up. At a depth of 100 ft, it starts to intoxicate the diver, and at 300 ft it can cause a loss of consciousness and even death. That's why divers don't use regular air at extreme depths.

for dangerous animals claws are poisonous.
Nitrogen is not a poisonous compound, around four fifths of the atmosphere is composed of nitrogen.
no they are not poisonous but they are dangerous
no.
Breathing 100% of it... No oxygen...
Yes and No, some seahorses are poisonous to keep their prey away and some seahorses are not poisonous.

Yes, they are poisonous creatures.
Yes, carbon monoxide is a poisonous and very dangerous gas.
ALL anemones are poisonous- that is how they catch their prey- but only a few are dangerous to people.
The adjective in the sentence is "dangerous." It describes the potential harm or risk posed by leaving a poisonous substance unmarked on the shelf.
