The G designation on hazard classifications refers to which type of agent?

Explanation:
The G designation identifies nerve agents in the hazard-classification system. These are the G-series organophosphates (for example, sarin, soman, and tabun) that inhibit acetylcholinesterase. When this enzyme is blocked, acetylcholine builds up at nerve synapses, causing a cholinergic crisis with symptoms such as excessive secretions, tearing, sweating, bronchial constriction, muscle twitching, and ultimately respiratory failure if not treated. Recognizing this designation helps responders anticipate the rapid onset and the specific protective measures and antidotes used for nerve-agent exposure.
