The wearie Traueiler, wandring that way, / Therein did often quench his thriſty heat, / And then by it his wearie limbes diſplay, / Whiles creeping ſlomber made him to forget[…]
I began also to feel very hungry, as not having eaten for twenty-four hours; and worse than that, there was a parching thirst and dryness in my throat, and nothing with which to quench it.

[…] others ſaying, the fire would ceaſe as ſoon as it had vent, uncovered a great part of the houſe, breaking down the roofs, and destroying all that ſtood in their way. None of them went about to quench the fire, but all were employed in pulling down the houſe, […]

A suitable method to prepare a system out of equilibrium in order to study the ensuing dynamics is to quench the system, i.e., to change its parameters abruptly.
If someone is pinned against the MRI magnet by a ferromagnetic object, you may need to quench the magnet in order to free them.

These knobs are generally mounted behind a cover of some sort, to prevent someone from leaning up against them or putting a philodendron on top of them, because (1) that aforementioned geyser can represent thousands to tens of thousands of dollars of helium these days, and (2) quenching is Not Good for the integrity of the magnet, and in the worse case you might find yourself with a lot of high-quality scrap metal.

There are two main types of quenches, and both are triggered by the red button. A customer of ours actually pushed his once, out of curiosity. And no, he was not 7 years old. This button is primarily for safety purposes. In some rare cases, clear signage is ignored and metal objects like mop buckets, oxygen tanks, etc. get sucked into the bore of the MRI. These are very difficult to remove while the magnet is at field. And, if a patient is somehow pinned inside, an emergency push of the quench button can be a lifesaver. The button artificially heats the magnet and starts the chain reaction described above.
