In 2015 author and right-to-die advocate Derek Humphry reported that Worthington Industries, the world's largest manufacturer of disposable helium cylinders, had announced that their helium cylinders will guarantee only 80% helium, with up to 20% air, making them inappropriate for use with a suicide bag in Humphry's opinion.

Helium storage and conservation is a process of maintaining supplies of helium and preventing wasteful loss. Helium is commercially produced as a byproduct of natural gas extraction. Until the mid-1990s, the United States Bureau of Mines operated a large scale helium storage facility to support government requirements for helium.
Man-portable anti-tank systems (MANPATS or MPATS) are traditionally portable shoulder-launched projectile systems firing heavy shell-type projectiles (although throwing and lunge weapons have existed), typically designed to combat protected targets, such as armoured vehicles, field fortifications and at times even low-flying aircraft (especially helicopters).
Liquid helium is a physical state of helium at very low temperatures at standard atmospheric pressures.Liquid helium may show superfluidity.. At standard pressure, the chemical element helium exists in a liquid form only at the extremely low temperature of −269 °C (−452.20 °F; 4.15 K).
A self-pressurising dewar (silver) being filled with liquid nitrogen from a larger storage tank (white). A cryogenic storage dewar (or simply dewar) is a specialised type of vacuum flask used for storing cryogens (such as liquid nitrogen or liquid helium), whose boiling points are much lower than room temperature.
The amount of helium that must be decanted is very simple to calculate: Multiply the desired gas fraction of helium (F He) by the total filling pressure (P tot) to get partial pressure of helium (P He). In the case of the Tx 20/40, in a 230 bar cylinder, this would be 230 bar x 40% = 92 bar (or for a 3,000 psi fill, it would require 3,000 x 40% ...
