Suicides using a suicide bag and an inert gas produce no characteristic post-mortem macroscopic or microscopic findings. [5] [17] Forensic death investigations of cause and manner of death may be very difficult when people die by suicide in this manner, provided the apparatus (such as the bag, tank, or tube) is removed by someone after death.
Toxic gases, by contrast, cause death by other mechanisms, such as competing with oxygen on the cellular level (e.g. carbon monoxide) or directly damaging the respiratory system (e.g. phosgene). Far smaller quantities of these are deadly. Notable examples of asphyxiant gases are methane, [1] nitrogen, argon, helium, butane and propane
Inhaling helium can be dangerous if done to excess, since helium is a simple asphyxiant and so displaces oxygen needed for normal respiration. [ 28 ] [ 186 ] Fatalities have been recorded, including a youth who suffocated in Vancouver in 2003 and two adults who suffocated in South Florida in 2006.
The following is a list of the causes of human deaths worldwide for different years arranged by their associated mortality rates. In 2002, there were about 57 million deaths. In 2002, there were about 57 million deaths.
The quantum mechanical effects on helium-3 and helium-4 are significantly different because with two protons, two neutrons, and two electrons, helium-4 has an overall spin of zero, making it a boson, but with one fewer neutron, helium-3 has an overall spin of one half, making it a fermion.
Helium inherited from the solar nebula likely became locked in Earth’s core as the planet formed, making the core a reservoir of noble gases. As helium-3 leaked from the core, it ascended to the ...
Helium is inert - it does not react with other substances or combust - and its atomic number is 2, making it the second lightest element after hydrogen. Rockets need to achieve specific speeds and ...
The Sarco pod (also known as Pegasos, and sometimes referred to as a "suicide pod" [1]) is a euthanasia device or machine consisting of a 3D-printed detachable capsule mounted on a stand that contains a canister of liquid nitrogen to die by suicide through inert gas asphyxiation.
