Strange designation for any fire-extinction agents (if so):

Intoxicative inhalants are a broad range of intoxicative drugs whose volatile vapors or gases are taken in via the nose and trachea.[1] They are taken by room temperature volatilization or from a pressurized container (e.g., nitrous oxide),
:
Many inhalants are volatile organic chemicals and can catch fire or explode,
:
A number of gases intended for household or industrial use are inhaled as recreational drugs. This includes chlorofluorocarbons used in aerosols and propellants (e.g., aerosol cooking spray or hair spray).

1,1,1,2-Tetrafluoroethane, R-134a, Forane 134a, Genetron 134a, Florasol 134a, Suva 134a or HFC-134a, also known as norflurane (INN), is a haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with less ozone depletion potential.
:
1,1,1,2-Tetrafluoroethane is an inert gas used primarily as a "high-temperature" refrigerant for domestic refrigeration and automobile air conditioners.
;
1,1,1,2-Tetrafluoroethane itself has an LD50 of 1,500 g/m3 in rats, making it relatively non-toxic, apart from the dangers inherent to inhalant abuse.

Carbon dioxide extinguishes flames, and some fire extinguishers, especially those designed for electrical fires, contain liquid carbon dioxide under pressure. Carbon dioxide extinguishers work well on small flammable liquid and electrical fires, but not on ordinary combustible fires, because although it excludes oxygen, it does not cool the burning substances significantly and when the carbon dioxide disperses they are free to catch fire upon exposure to atmospheric oxygen. Carbon dioxide has also been widely used as an extinguishing agent in fixed fire protection systems for local application of specific hazards and total flooding of a protected space.

According to the standard BS EN 3, fire extinguishers in the United Kingdom as all throughout Europe are red RAL 3000, and a band or circle of a second color covering between 5–10% of the surface area of the extinguisher indicates the contents. Before 1997, the entire body of the fire extinguisher was color coded according to the type of extinguishing agent.
The UK recognises Six fire classes:
• Class A fires involve organic solids such as paper and wood.
• Class B fires involve flammable or combustible liquids, including petrol, grease, and oil.
• Class C fires involve flammable gases.
• Class D fires involve combustible metals.
• Class E fires involve electrical equipment/appliances.
• Class F fires involve cooking fat and oil.
