Thank you teacher Anglika,
I like spot check which is fit for this sentence.
I am not a teacher!
If “spot check” = supervisory check on work performance or product quality done at random intervals and if “spot checks” are unannounced and can occur at any time so in my humble opinion there is a redundant word in the mentioned above expression “unannounced spot check”. "Unannounced" should be taken for granted.
A chemical waste plant has been closed down after a surprise inspection found toxic fumes were being released into the air.
Absolute Solvents Limited may now face prosecution for the leak from its factory in Westbury, Wiltshire.
The company must find the source and face strict tests before it can start work again.
It is likely to remain closed for several weeks.
Environment Agency inspectors discovered the leak when they made an unannounced spot-check.

Thank you for your insistence as well as for your kindness send me further information in the form of links.
Apparently, I gave out to my misleading inner conviction.
I think you advanced very knock-down arguments in favour of your expression.
