Poison by intraperitoneal route. Moderately toxic by ingestion and skin contact. A severe eye and skin irritant. Combustible; can react with oxidizing materials. To fight fire, use CO2, dry chemical. When heated to decomposition it emits toxic fumes of NOx.

2-N-Dibutylaminoethanol (CAS No.102-81-8) is an aminoalcohol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.It may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
