2-3-5 Gases Under Pressure (1)Definitions Definitions of gases under pressure in UN GHS are as follows, and they are adopted in this guidance. 【GHS 2 nd revised edition】(2.5.1) Gases under pressure are gases which are contained in a receptacle at a pressure of 200 kPa (gauge) or more, or which are liquefied or liquefied and refrigerated. They comprise compressed gases, liquefied gases, dissolved gases and refrigerated liquefied gases. (2)Classification criteria in GHS 【GHS 2 nd revised edition】(2.5.2) Gases are classified, according to their physical state when packaged, in one of four groups in the following table: Table 2.5.1: Criteria for gases under pressure Group Criteria Compressed gas A gas which when packaged under pressure is entirely gaseous at -50 °C; including all gases with a critical temperature ≤-50 °C. Liquefied gas A gas which when packaged under pressure, is partially liquid at Refrigerated liquefied gas temperatures above -50 °C. A distinction is made between: (a) High pressure liquefied gas: a gas with a critical temperature between -50°C and +65°C; and (b) Low pressure liquefied gas: a gas with a critical temperature above +65°C. A gas which when packaged is made partially liquid because of its low temperature. Dissolved gas A gas which when packaged under pressure is dissolved in a liquid phase solvent. The critical temperature is the temperature above which a pure gas cannot be liquefied, regardless of the degree of compression. (3) Guidance for Classification A) Judgment of Not applicable Substances and mixtures that are not compressed in pressure vessels (cylinders) shall be judged as “Not applicable”. 49
