40d:Fire-safe
| This article is about an older version of DF. |
Fire-safe materials are Template:L Template:Ls that are not damaged by Template:L. These include Template:L, Template:L, and Template:L. Template:L is not a fire-safe material, and neither are Template:L or Template:L (even though they are {{L|bar}s}). Fire-safe materials are only required when the object is going to come into contact with extreme heat, such as a Template:L, Template:L, Template:L, Template:L or Template:L, or for Template:L versions of these facilities.
Template:L materials, such as Template:L blocks, which are consumed in the purification of Template:L to produce Template:L, are considered fire-safe. It is perfectly fine to use Template:L as a flux material to make steel in a limestone smelter. Constructions will never melt or burn, regardless of what they're made of, but natural ice walls/floors/ramps/stairs will melt.
Fire-safety is supposed to require the item's material to be stable at temperatures below 11000 (1032°F, or about 555.6°C); due to a bug, however, it only requires that the material is incapable of burning (due to having no IGNITE_POINT). For this reason, Template:L is considered to be fire-safe.
Not to be confused with Template:L. Many fire-safe materials will still melt when submerged in Template:L, but that is not necessary for buildings that are powered by the stuff or items like doors or floodgates that may be adjacent to or in contact with magma, but are never surrounded on all sides by it.
