What H240 means
H240 is the GHS (Globally Harmonized System) hazard statement “Heating may cause an explosion.” It belongs to the Self-reactive / organic peroxide hazard class and appears in Section 2 of a Safety Data Sheet and on the product label when a substance or mixture meets the classification criteria for that class and category.
Where H240 applies, GHS assigns the signal word Danger and the GHS01 (Exploding bomb) pictogram. The exact signal word and pictogram set on a finished label come from the whole classification — the most severe endpoint drives the signal word, so a milder statement can be present without changing an already-Danger label.
