Convulsants are best described as which of the following?

• A. Poisons that cause seizures
• B. Substances that cause skin irritation
• C. Substances that relieve seizures
• D. Biological toxins only

Answer: (A)

Convulsants are chemicals that cause seizures by poisoning the nervous system. They are described as poisons that provoke convulsions, which is the defining hazard you’d look for in a response scenario. They’re not primarily about skin irritation, they don’t relieve seizures, and they aren’t limited to biological toxins—many chemical substances can trigger convulsions. So the best description is poisons that cause seizures.
