IARC group 2B

Substances, mixtures and exposure circumstances in this list have been classified by the International Agency for Research on Cancer (IARC) as Group 2B: The agent (mixture) is "possibly carcinogenic to humans". The exposure circumstance entails exposures that are possibly carcinogenic to humans. This category is used for agents, mixtures and exposure circumstances for which there is limited evidence of carcinogenicity in humans and less than sufficient evidence of carcinogenicity in experimental animals. It may also be used when there is inadequate evidence of carcinogenicity in humans but there is sufficient evidence of carcinogenicity in experimental animals. In some instances, an agent, mixture or exposure circumstance for which there is inadequate evidence of carcinogenicity in humans but limited evidence of carcinogenicity in experimental animals together with supporting evidence from other relevant data may be placed in this group. Further details can be found in the preamble to the IARC Monographs.

Column-generating template families

The templates listed here are not interchangeable. For example, using {{col-float}} with {{col-end}} instead of {{col-float-end}} would leave a <div>...</div> open, potentially harming any subsequent formatting.

Column templates

Type	Family	Handles wiki table code?†	Responsive/ mobile suited	Start template	Column divider	End template
Float	"col-float"	Yes	Yes	{{col-float}}	{{col-float-break}}	{{col-float-end}}
	"columns-start"	Yes	Yes	{{columns-start}}	{{column}}	{{columns-end}}
Columns	"div col"	Yes	Yes	{{div col}}	–	{{div col end}}
	"columns-list"	No	Yes	{{columns-list}} (wraps div col)	–	–
Flexbox	"flex columns"	No	Yes	{{flex columns}}	–	–
Table	"col"	Yes	No	{{col-begin}}, {{col-begin-fixed}} or {{col-begin-small}}	{{col-break}} or {{col-2}} .. {{col-5}}	{{col-end}}

^† Can template handle the basic wiki markup {| | || |- |} used to create tables? If not, special templates that produce these elements (such as {{(!}}, {{!}}, {{!!}}, {{!-}}, {{!)}})—or HTML tags (<table>...</table>, <tr>...</tr>, etc.)—need to be used instead.
