Which type of toxins are known for causing convulsions?

Convulsants are a category of toxins specifically known for their ability to induce convulsions in individuals exposed to them. These substances can affect the nervous system by disrupting normal neurological function, leading to the hyperactivity of neurons. When the brain becomes overly excitable due to the presence of these toxins, it can result in seizures or convulsions.

Understanding convulsants is crucial for responding to hazardous materials situations, as exposure can pose serious health risks and require immediate and appropriate medical intervention. In contrast, asphyxiants inhibit the body's ability to absorb oxygen; irritants primarily cause inflammation and damage to the respiratory system or skin; and contaminants generally refer to any harmful substances that are present but do not inherently indicate a specific physiological effect. Thus, the classification of convulsants specifically links their toxic effects to the induction of convulsive events, highlighting their role as a significant hazard in hazardous materials response scenarios.
