If you happen to be in the business where you are responsible for checking out and checking in equipment, you might need to create a form that manages this process. One way to do that is to make a list of the equipment that you could potentially loan out and make an identical list of the equipment that will be returned. When the equipment is checked out, place a tick next to this equipment. When the equipment is returned, compare it to the equipment checked out to see whether the two lists match.
