Question is in the title as I phrased. When an emergency happens in a plant and the entire process needs to be stopped immediately, what is the first equipment to shut down? I'm asking cuz I've never really had experience in the field.

What Is The First Thing To Do In An Emergency At A Plant?

Shutting down a plant depends on the process. The safe equipment state needs to be evaluated. An emergency stop may be as simple as 1) operator presses big red button 2) computer controls put the process into the desired condition. Uncontrolled shutdowns can happen. 'The plant lost all electric power.' 'The plant lost all instrument air.' 'The plant lost all cooling utility.' These are all hazards that need to be planned in advance with safeguards. Sometimes emergency stops cause physical damage to the process that cannot be easily avoided. This happens in fired furnaces where too little process flow allows equipment to overheat. Process liquids can become solids with loss of heating utility so that they no longer flow. Reactive materials require a lot of planning to avoid runaway reactions in an emergency. Each process is different.

#1. Follow the Emergency Plan (see Pillesar's post above).

Hi,
This is a tough one ! I don't know your role in the organization , you should talk with the operation guys .
Normally you have an emergency procedure in a plant where the situation has been anticipated (analyzed} based on your process and actions to perform : lack of power, lack of utility , Control system down , fire case , spillage of hazardous chemicals ,....
For sure you have an emergency red push button in the control room , check with the team what will happen , take a look at emergency matrix .
