| DOT-Kennzeichnung | Poison |
| Brandgefahren | When heated to decomposition, it emits toxic fumes of nitrogen oxides. (Non-Specific -- Combustible Liquid, n.o.s.) Flammable/combustible materialmay be ignited by heat, sparks, or flames. Vapors may travel to a source of ignition and flash back. Container may explode in heat of fire. (EPA, 1998) |
| Gesundheitsgefahren | This material is moderately toxic by ingestion, inhalation, and absorption through the skin. (EPA, 1998) |

| Reactivity Profile | PYRIDINE, 2-METHYL-5-VINYL- neutralizes acids in exothermic reactions to form salts plus water. Can polymerize exothermically. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides. |
