Answer: Fill-in-the-blank questions: The hazards of nitrogen to the human body: (causes suffocation); liquid nitrogen has a (frostbite-causing) effect on humans. ================================= ☛【HaiChuan Official Account】“Daily Recommendations” activity for various sections: http://bbs.hcbbs.com/thread-1603884-1-1.html (Source: HaiChuan Chemical Forum) ☛ Voting for the “I’m saving energy, where are you?” campaign in the petrochemical sector has started: http://bbs.hcbbs.com/thread-1606794-1-1.html
Nitrogen can cause suffocation, while liquid nitrogen can lead to frostbite
Asphyxiation, asphyxiation from frostbite. The vaporization of liquid nitrogen requires the absorption of a large amount of heat; if the body comes into contact with it, it can cause the body temperature to drop rapidly
Nitrogen is inert; generally speaking, it is harmless to humans. If it is all nitrogen, it can easily lead to death from asphyxiation. Furthermore, changes in pressure of nitrogen inhaled by the human body can be harmful to the brain. For example, when a diver comes back to the surface, they change their air tank. Astronauts undergo treatment before going outside the spacecraft.
Nitrogen causes asphyxiation in humans. Liquid nitrogen causes frostbite and asphyxiation in humans.
An excessive amount of nitrogen in the air reduces the partial pressure of oxygen inhaled, leading to hypoxia and asphyxiation. Liquid nitrogen: Accidental contact can easily cause frostbite
High concentrations of nitrogen can cause difficulty breathing
Harm of nitrogen to the human body: (Insufficient oxygen inhalation causes difficulty in breathing and a feeling of suffocation); liquid nitrogen is (suffocating and causes frostbite).
