EMTs dont go thru purses to look for allergies... Unless it happens that I hand in your purse to the LEO and he is kind enough to let me know what he found in your walet. If you are allergic to something that can kill you medic alert tags (braclets and neckless) are the way to go. Rule of trauma scene is somethng we call 'golden hour" you need to be under hot lights and cold steel from time I receive the call under an hour.

Great idea on keeping your tools on the leash. But in case of rollover leashed tool is something that would bang you on the head over and over again. How about using retention straps made out of velcro?
