The template requires one or more phrase codes as input:

• {{GHS phrases|H220|H230}} → H220, H230
• {{H-phrases|H220|H230}} → H220, H230
• {{P-phrases| P220 | P230}} → P220, P230
• {{H-phrases|H302 + 312}} → H302+H312 -- (Predefined combination, recognised)

Pages with errors or warnings show a Preview message. Articles are then listed in Category:GHS errors (0), Category:GHS warnings (1).

While one can use {{GHS phrases}} stand-alone in text, more common use is in {{Chembox}}, section Chembox Hazards:

{{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}}
 }}
}}

For ease of working in {{Chembox}}, the templates have synonyms (redirects) same as the Chembox parameter name:

|Section3 = {{Chembox Hazards
 | HPhrases = {{HPhrases|H300}}
 | PPhrases = {{PPhrases|P300}}
 }}

• The number of phrase code one can enter is practically unlimited. The codes are ordered alphanumeric.

Best practice: add prefix H or P to the number: |H220, not |220.

One template call can only show one prefix set. That is, H- and P-phrases cannot be mixed.

• |setid= (H or P) can be set to prevent ambiguity in generic {{GHS phrases}}.

For backward compatability, the code prefix "H" or "P" is not required. So {{H-phrases|220}} equals {{H-phrases|H220}} → H220. However. Since {{GHS phrases}} covers both H and P, adding the prefix is better.

• {{GHS phrases/list omit rules}}

|omit=true (default)

• {{GHS phrases|H314|H318}} → H314

Repeated phrase codes are removed (hidden):

• {{GHS phrases|H400|H401|H401|H401}} → H400, H401

• {{GHS phrases/inline}} -- inline, with full phrase text
• {{GHS phrases/list_all}} -- table, by |setid=H, P
• {{GHS phrases/number of phrases}} -- by |setid=H, P
• {{GHS phrases/list omit rules}} -- table, documentation

Phrase codes that are unknown get an inline marker like , give a warning in preview and are categorised in Category:GHS errors when in article space.

For example (One can see the warning when previewing this page or section):

• {{H-phrases|H220|H999}} → H220, H999

{{H-phrases|H200|H241}} → H200, H241

{{H-phrases|H302+H312}} → H302+H312

{{P-phrases|P101|P263}} → P101, P263

{{P-phrases|P306+P360}} → P306+P360

• {{GHS phrases|H220}} → H220
• {{GHS phrases|P220}} → P220

• {{GHS phrases/inline}} lists the phrases inline, to be used in regular sentences.

{{GHS phrases/inline|H220|H401}} → H220: "Extremely flammable gas", H401: "Toxic to aquatic life"

Errors

All errors show a preview-message in Preview.

Categorisation is in Category:GHS errors (1), articles only (mainspace).

• |setid=H, P, <blank> missing
• |setid=XYZ not recognised

When entered: in {{GHS phrases}}, a setid check is enforced. Is present by default in {{H-phrases}} etc.

When setid is missing, any first setid in the codes-list is used. So |310 |3220 |H333 → H.

This also occurs when setid=H and a P-phrase is entered.

In certain listings, like {{GHS phrases/list all}}, a blank setid returns the full list (all H- and P-phrases). No error.

Catsort: H, P,

• Phase codes that are not in the list (like |H999) generate an error → error

• Parameter unknown |foo=: catsort under U
