P210 — Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking.

02 · Legal status

Where P210 is current

GHS is a United Nations model text, revised every two years, and each jurisdiction adopts a revision on its own timetable. A code can be legally current in one system and deleted in another — that is normal, not an error.

Currently in force under: EU CLP, US OSHA HazCom, US HazCom 2012, UN GHS. Sources: EU CLP · US OSHA HazCom · US HazCom 2012 · UN GHS

Substances carrying P210

Every entry whose harmonised CLP Annex VI classification includes this precautionary statement. Substances with a reference page here open on this site; the rest open on ghssymbols.com. Of these, 11 are group entries such as “beryllium compounds” or “salts of hydrazine” — Annex VI gives them no CAS number, so they are listed by Index No and have no page of their own.
