What H280 means
H280 is the GHS (Globally Harmonized System) hazard statement “Contains gas under pressure; may explode if heated.” It belongs to the Gas under pressure 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 H280 applies, GHS assigns the signal word Danger and the GHS04 (Gas cylinder) 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.

GHSLogic reads the hazard and precautionary statements straight off your supplier SDSs, classifies the whole mixture across every GHS endpoint, and drafts a review-ready SDS and labels.
Reference information, not a compliance determination. Actual label elements depend on the full classification of your specific substance or mixture and require review by a qualified professional.
