Sarcasm, if that wasn’t obvs. The highlighted comment is explaining what the device does.
The comment directly below it pointing out that it’s in a red power outlet is referring to the fact that red power outlets in hospitals almost if not universally denote outlets connected to gas generators (or another type of fuel that can be kept onsite). Red outlets won’t lose power if the city or other local power grid fails, so those red outlets are supposed to be reserved for truly essential equipment like ventilators and IV pumps running critical meds that can’t be interrupted for even a few minutes. And they plugged the employee surveillance device into one.
That said, consistent hand-washing like that has been proven to reduce hospital based infections quite a bit and compliance to regulations alone is often very poor.
You can argue that understaffing is the ultimate cause of poor compliance, but then again… the number of anti-vaxxers in hospital staff is surprisingly high.
