What action should responders take if exposed to sarin gas and begin to show signs?

• A. Inhale amyl nitrate poppers one at a time for 12 minutes
• B. Have the treatment officer start an IV and provide a fluid challenge to support vital signs
• C. Leave the hot zone and seek immediate transport to the nearest hospital for decon
• D. Self administer the appropriate number of DuoDote/Mark 1 auto injectors

Answer: (D)

When a nerve agent like sarin is involved and someone starts showing signs, the immediate lifesaving step is to deliver the field antidotes as soon as possible. These auto-injectors contain atropine, which blocks the harmful muscarinic effects (secretions, bronchospasm, bradycardia), and pralidoxime, which helps restore the enzyme that nerve agents disable. Self-administering the appropriate number of DuoDote or Mark I auto-injectors promptly reduces the progression of the cholinergic crisis and buys time for decontamination and further care.

After giving the antidote(s), you should begin field decontamination to limit ongoing absorption and then seek medical care. Amyl nitrite is not an antidote for nerve agents, and while maintaining circulation is important, delaying antidote treatment for IV fluids or transport would worsen outcomes. Leaving the hot zone without first addressing the exposure would miss the critical, time-sensitive intervention the body needs right away.
