With all defibrillators, it's necessary to carry the defibrillator unit, defibrillator pads for both adults and children and a first-aid kit. It's also worth investing in all adequate signage to raise awareness with your passengers that an AED is available. For use at bus stops, train stations and airports you'll need a defibrillator cabinet to house the AED and the other equipment. When adding a defibrillator onboard you may want to consider a carry case.
