Back when I started to work on ambulances, the service I was with was still wearing all white uniforms. A hold over from the days of “scope and run”; the men in the white jackets are coming for you, etc. Ever try to keep white pants clean in a dirty occupation? After much lobbying we finally got permission to ditch the white paints for blue ones with a white shirt. Now it seems their all wearing dark uniforms, so it went from one extreme to the next.
One time we responded to a neighboring services request for a paramedic. They were still wearing all white and commented on how we looked unprofessional with our blue paints. Cloths don’t always make the medic.
