What H260 means
H260 is the GHS (Globally Harmonized System) hazard statement “In contact with water releases flammable gases which may ignite spontaneously.” It belongs to the Emits flammable gas in contact with water 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 H260 applies, GHS assigns the signal word Danger and the GHS02 (Flame) 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.
