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
[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. [4] [17] Petechiae, which are often considered a marker of asphyxia, are present in only a small minority of cases (3%). [40]
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 method of suicide based on self-administration of helium in a bag, a colloquial name being the "exit bag" or suicide bag, has been referenced by some medical euthanasia advocacy groups. [36] Originally, such bags were used with helium, and 30 deaths were reported with use of them from 2001 to 2005, and another 79 from 2005 to 2009.

The Occupational Safety and Health Administration (OSHA) regulation (1910.134(b)) defines the term as "an atmosphere that poses an immediate threat to life, would cause irreversible adverse health effects, or would impair an individual's ability to escape from a dangerous atmosphere."
Helium also has a very low boiling point (-268.9°C or -452°F), allowing it to remain a gas even in super-cold environments, an important feature because many rocket fuels are stored in that ...
Avicii was found dead in the afternoon hours of April 20, 2018, according to a statement from his rep. His tragic death came two years after he announced his retirement from touring in March 2016.
