The templates '''{{tlt|GHS phrases}}''' ([[:Template:GHS phrases/testcases|/tests]]), '''{{tl|H-phrases}}''' and '''{{tl|P-phrases}}''' all format and present [[Globally Harmonized System of Classification and Labelling of Chemicals|GHS hazard and precaution statements]] as defined by the UN.{{GHS2021|ref|annex=3}}

The template requires one or more phrase codes as input:
* <code><nowiki>{{GHS phrases|H220|H230}}</nowiki></code> &rarr; {{GHS phrases|H220|H230}}
* <code><nowiki>{{H-phrases|H220|H230}}</nowiki></code> &rarr; {{H-phrases|H220|H230}}
* <code><nowiki>{{P-phrases| P220 | P230}}</nowiki></code> &rarr; {{P-phrases| P220 | P230}}
* <code><nowiki>{{H-phrases|H302  + 312}}</nowiki></code> &rarr; {{H-phrases|H302  + 312}} <small>-- (Predefined combination, recognised)</small>

Pages with errors or warnings show a {{button|Preview}} message. Articles are then listed in {{clc|GHS errors|pages}}, {{clc|GHS warnings|pages}}.

==Usage==
:While one can use {{tl|GHS phrases}} stand-alone in text, more common use is in {{tl|Chembox}}, section {{code|Chembox Hazards}}:
{{Chembox|container_only=yes
| Name=[[DDT]] GHS phrases
| Section7 = {{Chembox Hazards
| HPhrases = {{H-phrases|H301|H351|H372|H410}}
| PPhrases = {{P-phrases|P201|P202|P260|P264|P270|P273|P281|P301+P310|P308+P313|P314|P321|P330|P391|P405|P501}}
}}}}
<pre>
{{Chembox
| Section7 = {{Chembox Hazards
| HPhrases = {{H-phrases|H301|H351|H372|H410}}
| PPhrases = {{P-phrases|P201|P202|P260|P264|P270|P273|P281|P301+P310|P308+P313|P314|P321|P330|P391|P405|P501}}
}}
}}
</pre>

===Synonyms: {{tlf|HPhrases}}===
For ease of working in {{tlf|Chembox}}, the templates have synonyms (redirects) ''same as the Chembox parameter name'':

 <code><nowiki>|Section3 = {{Chembox Hazards</nowiki></code>
 {{para|HPhrases|<nowiki>{{HPhrases|H300}}</nowiki>}}
 {{para|PPhrases|<nowiki>{{PPhrases|P300}}</nowiki>}}
 <code><nowiki> }}</nowiki></code>


===Parameters===
* The number of phrase code one can enter is practically unlimited. The codes are ordered alphanumeric.
:'''Best practice''': ''add prefix {{mono|H}} or {{mono|P}} to the number'': {{xt|{{!}}H220}}, not {{!xt|{{!}}220}}.
:One template call can only show one prefix set. That is, {{mono|H}}- and  {{mono|P}}-phrases cannot be mixed.
* {{para|setid|}} ({{mono|H}} or {{mono|P}}) can be set to prevent ambiguity in generic {{tlf|GHS phrases}}.

For backward compatability, the code prefix "H" or "P" is not required. So <code><nowiki>{{H-phrases|220}}</nowiki></code> equals <code><nowiki>{{H-phrases|H220}}</nowiki></code> &rarr; {{H-phrases|H220}}. However. Since {{tl|GHS phrases}} covers both {{mono|H}} and {{mono|P}}, adding the prefix is better.

==Code checks added==
===Omit Rules===
* {{tl|GHS phrases/list omit rules}}
:{{para|omit|true}} (default)
{{GHS phrases/list omit rules|expand=false}}

* <code><nowiki>{{GHS phrases|H314|H318}}</nowiki></code> &rarr; {{GHS phrases|H314|H318}}

===Remove Doubles===
Repeated phrase codes are removed (hidden):
* <code><nowiki>{{GHS phrases|H400|H401|H401|H401}}</nowiki></code> &rarr; {{GHS phrases|H400|H401|H401|H401}}

==Other functions==
* {{tl|GHS phrases/inline}} -- inline, with full phrase text
* {{tl|GHS phrases/list_all}} -- table, by {{para|setid|H, P}}
* {{tl|GHS phrases/number of phrases}} -- by {{para|setid|H, P}}
* {{tl|GHS phrases/list omit rules}} -- table, documentation
* {{para|list|}} -- See {{slink||List options}}
===List options===
* Using {{para|list}}, {{tl|GHS phrases}} can be presented in various ''list formats'':
:{{para|1=list|2=abbr, inline, bulleted, unbulleted, horizontal, ordered, horizontal_ordered}}
; {{para|listtype|abbr}} {{nobold|(default)}}
:{{GHS phrases|P201 |P302+P334 |P502 |listtype=abbr}}

; {{para|listtype|inline}}
:{{GHS phrases|P201 |P302+P334 |P502 |listtype=inline}}

; {{para|listtype|bulleted}}
:{{GHS phrases|P201 |P302+P334 |P502 |listtype=bulleted}}

; {{para|listtype|unbulleted}}
:{{GHS phrases|P201 |P302+P334 |P502 |listtype=unbulleted}}

; {{para|listtype|horizontal}}
:{{GHS phrases|P201 |P302+P334 |P502 |listtype=horizontal}}

; {{para|listtype|ordered}}
:{{GHS phrases|P201 |P302+P334 |P502 |listtype=ordered}}

; {{para|listtype|horizontal_ordered}}
:{{GHS phrases|P201 |P302+P334 |P502 |listtype=horizontal_ordered}}

* Except for {{mono|abbr, inline}}, these list formats are defined in [[:Module:List]]

==Errors and warnings==
Phrase codes that are unknown get an inline marker like <sup><nowiki>[?]</nowiki></sup>, give a warning in {{button|preview}} and are categorised in {{cl|GHS errors}} when in article space.
