ADR hazard number 333
Hazard identification number 333 on the orange plate: pyrophoric liquid.
Printed in the upper half of the orange-coloured plate above the UN number, 333 identifies a pyrophoric liquid. This is one of the figure combinations that 5.3.2.3.1 gives a special meaning, read as a whole rather than figure by figure.
| 3 | flammable liquid (vapours) or gas, or a self-heating liquid |
|---|---|
| 3 | repeated 3: doubling a figure means that hazard (flammable liquid) is intensified |
| 3 | repeated 3: doubling a figure means that hazard (flammable liquid) is intensified |
Note. 5.3.2.3.1 lists 333 among the combinations with a special meaning, so read it as a whole from the 5.3.2.3.2 list; the per-figure reading in digits[] does not fully apply. Number and meaning pairing checked against a second text extraction of the list.
Refers to: 5.3.2.3.1; 5.3.2.2.3; Table A column (20).
