What H220 means
H220 is the GHS (Globally Harmonized System) hazard statement “Extremely flammable gas.” It belongs to the Flammable gas 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 H220 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.
