Which statement about sarin nerve gas indicates its hazard level and typical response?

• A. High lethality
• B. It is safe to breathe in after release
• C. Routine antibiotics neutralize exposure
• D. It is harmless to humans

Answer: (A)

Sarin is a highly toxic nerve agent that rapidly inhibits acetylcholinesterase, causing a surge of acetylcholine and a quick, dangerous cholinergic crisis. This makes its hazard level very high, with the potential for death from respiratory failure or seizures even after brief exposure. The typical emergency response centers on rapid decontamination and aggressive medical treatment: atropine to block muscarinic effects, pralidoxime to reactivate the enzyme, and supportive care such as securing the airway and providing breathing support. Statements that it’s safe to breathe after release, that routine antibiotics neutralize exposure, or that it’s harmless to humans are inconsistent with its potency and mechanism. The one that best reflects both the danger and the urgent, antidotal approach is that it is highly lethal.
