Toxicology

3-Aminopyridine can easily be absorbed through the skin. It is fatal if swallowed or absorbed through the skin. High concentrations can be extremely destructive to the tissues of mucous membranes and upper respiratory tract eyes and skin. Symptoms may also include convulsions and death. It also causes damage to the nervous system. Thermal decomposition leads to evolution of toxic gases such as carbon monoxide and oxides of nitrogen.
