If you lose your passport, you should contact the embassy without delay.

If you lose your passport, you should contact the embassy without delay.
Hello,
I saw this sentence example in Longman Dictionary.
Can we use without delay at the beginning of the sentence or in different contexts or not?

For example: [color=blue]without delay, If you lose your passport, you should contact the embassy.

Any thoughts?
Thank you

No, that does not work.

Many thanks.
