Your employer has invested in your safety and that of your co-workers by purchasing an Automated External Defibrillator (AED). You and some of your colleagues have even given up a couple of hours of your valuable time to get trained in CPR and using these life-saving devices. Its fairly simple to use these things, they tell you what to do once you switch them on and won't shock somebody unless they need it anyway.
