Chemical hazard pictograms (GHS) are drawings, and Unicode has no characters for them, so there is no copyable corrosive, oxidizing or irritant symbol. These are the nearest characters: the flame stands for flammable and oxidizing substances, the explosion for explosives, the test tube for chemicals in general. For toxic substances use ☠ above, and for harmful or irritant substances ❗. A label that has to be official needs the pictogram from the regulation.
Copy the no sign (prohibited) symbol and related prohibition and no-entry markers for warnings and notices.
