The second item is definitely a match box lable, not a cinderella.
The first one (part of a sheet) is really a trade union stamp - it's a monthly membership fee stamp with a pay stub under it.
You (or your Google tramnslator) are quite right about the translation of the upper word in capital letters - "All-Union Central Council of Trade Unions"
But I see nothing that might be translated as "Professional risk"
The two words above the hammer and the sickle read "Unified trade union stamp", the ones below - "membership fee / 1 r(uble) 50 k(opecks)
The text in the stub reads "Trade Union pay stub / 1 r 50 k"
This stamp must be from the 1960s
When the fee was paid (every month), the upper stamp was glued in the worker's Trade Unions personal membership card#1073; while the other part (pay stub) was glued onto his/her registration card in the office, for control purposes. These stamps went out of use in the 1970s, as far as I know.
This stamp was used all around the USSR.
