Class 2 - Flammable Gas / Non-Flammable Non-Toxic Gas / Toxic Gas
Hazard labels of Class 2 are essential for the safe and legally compliant marking of gases and gaseous substances. Depending on their properties, these substances can be – flammable (2.1), asphyxiating, oxidizing (2.2) or toxic (2.3) and pose particular risks during transport. The subclasses
Correct labeling according to ADR, RID, IMDG and IATA is therefore crucial to make hazards identifiable at an early stage.

1 to 9 (from a total of 9)
Die Klasse 2 includes pure gases and gas mixtures, defined as substances that:
have a vapor pressure of > 300 kPa (3 bar) at 50 °C or are completely gaseous at 20 °C and 101.3 kPa.
The subclasses of Dangerous Goods Class 2
- Class 2.1 – Flammable Gases (“Flammable Gas”)
These gases can form explosive mixtures with air and ignite easily.
Examples: propane, hydrogen, butane.
Hazards: fire hazard, explosion hazard, risk of asphyxiation.
- Class 2.2 – Non‑flammable, non‑toxic gases (“Non‑Flammable Gas”)
These gases are not flammable but can act as asphyxiants or become dangerous under pressure.
Examples: helium, nitrogen, carbon dioxide.
- Class 2.3 – Toxic gases (“Toxic Gas”)
Gases of this subclass are highly dangerous and can cause severe health damage even in small quantities.
Examples: chlorine, ammonia.
