Turnstiles with a built-in breathalyzer appeared in Russia

A video began to circulate on social networks in which, allegedly, workers of a St. Petersburg plant pass through a “smart” turnstile with a built-in breathalyzer. That is, to get to work, a factory worker needs to blow twice into a special window. And if the “breathalyzer” senses something is wrong, the employee will be sent home. Do you think such an invention will help them?
