emergency shutdown
Urgent system stop
An emergency shutdown is the rapid, forced stopping of a system, machine, or facility when continued operation poses danger.
Power plants have emergency shutdown procedures for reactor failures; industrial equipment has emergency shutdown buttons.
The term appears in computing, manufacturing, and energy contexts: The refinery initiated an emergency shutdown after detecting a gas leak.
