What H317 means
H317 is the GHS (Globally Harmonized System) hazard statement “May cause an allergic skin reaction (skin sensitizer).” It belongs to the Skin sensitization 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 H317 applies, GHS assigns the signal word Warning and the GHS07 (Exclamation mark) 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.
