Usage tips
Compound word
The word is composed of 'die Not' (distress, danger) and 'der Fall' (situation, event). A 'Notfall' (emergency) is therefore literally a 'case of distress,' a sudden, dangerous situation.
EXAMPLE
Im Notfall müssen Sie diese Nummer anrufen.
In an emergency, you must call this number.
Use as a noun
Much more common than the rare adjective is the noun 'der Notfall' (emergency). In most situations, people speak of 'einem Notfall' (an emergency) or use the prepositional phrase 'im Notfall' (in an emergency).
EXAMPLE
Was machst du in einem Notfall?
What do you do in an emergency?
Typical expressions
As a noun, 'der Notfall' (emergency) is often used in fixed expressions. The most important ones are 'im Notfall' (if the situation occurs / in an emergency) and 'für den Notfall' (as a precaution / in case of emergency).
EXAMPLE
Für den Notfall habe ich immer eine Taschenlampe im Auto.
I always keep a flashlight in the car in case of emergency.
Invariable adjective
As an adjective, 'Notfall' (emergency) is invariable (indeclinable) and is not declined. It is often used in technical or administrative contexts to name a state or mode.

Notfall vs dringend
urgent / urgently
'dringend' and 'Notfall' can both have to do with a serious situation in which action must be taken quickly. 'dringend' directly describes that something must be done immediately or very soon. It fits tasks, appointments, problems, or requests. 'Notfall' as a descriptive word is used more in fixed technical or organizational expressions, for example for things intended for a serious situation. The words can be confused because an emergency is often urgent. But not every urgent matter is an emergency.
Notfall
Im Büro hängt ein Notfall-Plan neben der Tür.
There is an emergency plan hanging next to the door in the office.
dringend
Mein Kollege muss heute dringend mit der Ärztin sprechen.
My colleague urgently needs to speak with the doctor today.
