▼B 1.1.1. ◄ EUH014 — ‘Reacts violently with water’

For substances and mixtures which react violently with water, such as acetyl chloride, alkali metals, titanium tetrachloride.

►M19 1.1.2. ◄ EUH018 — ‘In use, may form flammable/explosive vapour-air mixture’

For substances and mixtures not classified as flammable themselves, which may form flammable/explosive vapour-air mixtures. For substances this might be the case for halogenated hydrocarbons and for mixtures this might be the case due to a volatile flammable component or due to the loss of a volatile non-flammable component.

►M19 1.1.3. ◄ EUH019 — ‘May form explosive peroxides’

For substances and mixtures which may form explosive peroxides during storage, such as diethyl ether, 1,4-dioxane.

►M19 1.1.4. ◄ EUH044 — ‘Risk of explosion if heated under confinement’

For substances and mixtures not in themselves classified as explosive in accordance with section 2.1 of Annex I, but which may nevertheless display explosive properties in practice if heated under sufficient confinement.
