What H311 means
H311 is the GHS (Globally Harmonized System) hazard statement “Toxic in contact with skin.” It belongs to the Acute toxicity (dermal) 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 H311 applies, GHS assigns the signal word Danger and the GHS06 (Skull and crossbones) 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.
