While asphyxiation by helium can be detected at autopsy, there is currently no test that can detect asphyxiation by nitrogen. For this reason, nitrogen is commonly the preferred choice for people who do not want the cause of death established. [4] [5] [6] Suicide bags were first used during the 1990s. The method was mainly developed in North ...
Liquid nitrogen is a compact and readily transported source of dry nitrogen gas, as it does not require pressurization. Further, its ability to maintain temperatures far below the freezing point of water, specific heat of 1040 J ⋅kg −1 ⋅K −1 and heat of vaporization of 200 kJ⋅kg −1 makes it extremely useful in a wide range of ...
A closely related mixture, sometimes called "base piranha", is a 5:1:1 mixture of water, ammonia solution (NH 4 OH, or NH 3 (aq)), and 30% hydrogen peroxide. [2] [3] As hydrogen peroxide is less stable at high pH than under acidic conditions, NH 4 OH (pH c. 11.6) also accelerates its decomposition.
Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.
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. "Sarco" is short for "sarcophagus".
3 liter can of recreational nitrous oxide to fill up balloons. A report from Consumers Union report from 1972 (based upon reports of its use in Maryland 1971, Vancouver 1972, and a survey made by Edward J. Lynn of its non-medical use in Michigan 1970) found that use of the gas for recreational purposes was then prevalent in the US and Canada ...
To decrease the risk of asphyxiation, there have been proposals to add warning odors to some commonly used gases such as nitrogen and argon. However, CGA has argued against this practice. They are concerned that odorizing may decrease worker vigilance, not everyone can smell the odorants, and assigning a different smell to each gas may be ...
Pyridine N-oxide is five orders of magnitude less basic than pyridine: the pK a of protonated pyridine-N-oxide is 0.8. [7] Protonated derivatives are isolable, e.g., [C 5 H 5 NOH]Cl. [3]
