What H271 means
H271 is the GHS (Globally Harmonized System) hazard statement “May cause fire or explosion; strong oxidizer.” It belongs to the Oxidizing liquid/solid 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 H271 applies, GHS assigns the signal word Danger and the GHS03 (Flame over circle) 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.
