You can plan for, and define responses to, emergencies. That doesn't make them not emergencies.

Why do I feel like this thread is giving the word emergency an existential crisis :)

To be an emergency or not to be an emergency, that is the question!

An common use of "emergency" in a similar manner, if I have stomach issues and need to use the toilet now, I will call the situation an emergency even if I haven't yet soiled my pants. If I reach the bathroom in time, the emergency ends with no major incident.

Quite right. If there is a fire in your house, it is still an emergency even if you have an extinguisher and evacuation plan.

Above didn't say that, everything someone planned for is "not unexpected" to some degree, but doesn't make it less an emergency or deviation from normal operation or how you want to call it?

They have contracts in place that promise savings in exchange of shutdowns at peaks. You can't get more normal and regulated than that.

So was my surgery for testicular torsion. Still considered a (medical) emergency.
