I was a LEO for 30+ years, EMT for 20+. I still have a pocket mask and gloves in my car kit. Carried a shield/gloves in a cargo pocket for years, finally stopped. I have never had to do a thing off duty (lucky me). On duty I did full blown CPR probably 20+ times, once for over a half hour (talk about tired!). Lost every one of them (all from closed head injuries after being ejected from an overturning vehicle at high speeds...wear those seat belts)...
