There’s also a bunch of contexts where workers wear scrubs but the exposure to contaminants is low or basically nonexistent

Like I worked in a psych hospital and the nurse practitioners were required to wear scrubs. They saw people on an outpatient basis 90% of the time or more. Their job was to sit in an office, have someone come in, interview them for a bit, write scripts, then repeat until the day was done basically. They may take temperature or blood pressure.

They were required to wear scrubs because occasionally if the inpatient dept was short staffed they would be asked to come on the floor and there you would have a much higher risk of bodily fluid exposure. But the vast majority of the time their scrubs were absolutely pristine
