Because the liquid-to-gas expansion ratio of nitrogen is 1:694 at 20 °C (68 °F), a tremendous amount of force can be generated if liquid nitrogen is vaporized in an enclosed space. In an incident on January 12, 2006 at Texas A&M University, the pressure-relief devices of a tank of liquid nitrogen were malfunctioning and later sealed. As a ...
Nitrogen had been used to flush oxygen from the compartment as a precaution against fire. They were not wearing air packs because of a last-minute change in safety procedures. [23] During a pool party in Mexico in 2013, eight party-goers were rendered unconscious and one 21-year-old male went into a coma after liquid nitrogen was poured into ...
The risk of breathing asphyxiant gases is frequently underestimated leading to fatalities, typically from breathing helium in domestic circumstances and nitrogen in industrial environments. [ 12 ] The term asphyxiation is often mistakenly associated with the strong desire to breathe that occurs if breathing is prevented.
The inventor feels that "where you die is certainly an important factor". [7] The capsule of Sarco provides for a rapid decrease in oxygen level while maintaining a low level of carbon dioxide. On activation, 4 litres (1.1 US gal) of liquid nitrogen causes the oxygen level to drop silently to less than 5% in less than one minute.
[17] [35] This is because nitrogen is five times more soluble in fat than in water, leading to greater amounts of total body dissolved nitrogen during time at pressure. Fat represents about 15–25 percent of a healthy adult's body, but stores about half of the total amount of nitrogen (about 1 litre) at normal pressures.
Nitrogen gas or oxygen-depleted air has been considered for human execution, as it can induce nitrogen asphyxiation. The victim detects little abnormal sensation as the oxygen level falls. This leads to asphyxiation (death from lack of oxygen) without the painful and traumatic feeling of suffocation, or the side effects of poisoning. [56]
In Sweden, which has had civil unions since 1995 and full marriage since 2009, men married to men have triple the suicide rate of men married to women. All of these unbearable statistics lead to the same conclusion: It is still dangerously alienating to go through life as a man attracted to other men.
A person can cause frostbite by accidental prolonged contact, using an aerosol on one place for too long. [11] This is often done with deodorants, but other products such as asthma inhalers are also common causes of injury. Injuries are especially common with younger children who "try it out" not knowing all the possible dermatological effects.
