Hazard statements form part of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). They are intended to form a set of standardized phrases about the hazards of chemical substances and mixtures that can be translated into different languages.〔The United Nations has published the list of GHS hazard statements in all UN official languages (Arabic, Chinese, English, French, Russian, Spanish): it can be found in Annex 3 of GHS Rev.2 for the corresponding language.〕〔A list of translations into all the European Union official languages can be found in Annex III to the CLP Regulation, on pages 146–91 of the official English-language version for the GHS statements and pages 192–209 for the EU-specific statements.〕 As such, they serve the same purpose as the well-known R-phrases, which they are intended to replace. Hazard statements are one of the key elements for the labelling of containers under the GHS, along with:〔Part 1, section 1.4.10.5.2, GHS Rev.2〕 *an identification of the product; *one or more hazard pictograms (''where necessary'') *a signal word – either Danger or Warning – where necessary *precautionary statements, indicating how the product should be handled to minimize risks to the user (as well as to other people and the general environment) *the identity of the supplier (who might be a manufacturer or importer) Each hazard statement is designated a code, starting with the letter H and followed by three digits. Statements which correspond to related hazards are grouped together by code number, so the numbering is not consecutive. The code is used for reference purposes, for example to help with translations, but it is the ''actual phrase'' which should appear on labels and safety data sheets.〔Part 1, section 1.4.10.5.2(b)(ii), GHS Rev.2〕 == Physical hazards == * H200: Unstable explosive * H201: Explosive; mass explosion hazard * H202: Explosive; severe projection hazard * H203: Explosive; fire, blast or projection hazard * H204: Fire or projection hazard * H205: May mass explode in fire * H220: Extremely flammable gas * H221: Flammable gas * H222: Extremely flammable aerosol * H223: Flammable aerosol * H224: Extremely flammable liquid and vapour * H225: Highly flammable liquid and vapour * H226: Flammable liquid and vapour * H227: Combustible liquid * H228: Flammable solid * H229: Pressurized container: may burst if heated * H230: May react explosively even in the absence of air * H231: May react explosively even in the absence of air at elevated pressure and/or temperature * H240: Heating may cause an explosion * H241: Heating may cause a fire or explosion * H242: Heating may cause a fire * H250: Catches fire spontaneously if exposed to air * H251: Self-heating; may catch fire * H252: Self-heating in large quantities; may catch fire * H260: In contact with water releases flammable gases which may ignite spontaneously * H261: In contact with water releases flammable gas * H270: May cause or intensify fire; oxidizer * H271: May cause fire or explosion; strong oxidizer * H272: May intensify fire; oxidizer * H280: Contains gas under pressure; may explode if heated * H281: Contains refrigerated gas; may cause cryogenic burns or injury * H290: May be corrosive to metals 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「GHS hazard statements」の詳細全文を読む スポンサード リンク
