Nickel carbonyl
Nickel carbonyl (IUPAC name: tetracarbonylnickel) is a nickel(0) organometallic compound with the formula Ni(CO)4. This colorless liquid is the principal carbonyl of nickel. It is an intermediate in the Mond process for producing very high-purity nickel and a reagent in organometallic chemistry, although the Mond Process has fallen out of common usage due to the health hazards in working with the compound. Nickel carbonyl is one of the most dangerous substances yet encountered in nickel chemistry due to its very high toxicity, compounded with high volatility and rapid skin absorption Wikipedia

Segregation chart for load, transport, and storage
This chart shows whether loading, transport, or storage with other hazard classes is permitted, prohibited, or restricted. Based on 49 CFR §177.848.
Hinweis: In der Kompatibilitätstabelle sind Stoffe der Gefahrenklasse 6.1 nur dann gesondert zu berücksichtigen, wenn der Stoff als inhalativ giftig (Gefahrenzone A) sowie in der Verpackungsgruppe I eingestuft ist. Siehe Sonderbestimmung 1 sowie PHMSA Interpretation #09-0252.
Packages with POISON or POISON INHALATION HAZARD labels, or a POISON label displaying “PG III,” or “PG III” marked next to a POISON label may not be transported with foodstuffs, feed or any other edible material, intended for humans or animals. For exceptions see 49 CFR §177.841(e).
Currently HazMat Tool is not able to to check if a HazMat is liquid or not. Therefore it is assumed as liquid.
