First levers always follow the order: Load fulcrum effort/force. The load is at one end of the lever and the force is applied at the other end. The fulcrum is somewhere in between the load and force. Scissors are examples of 1st class levers or when elevating one's head above one's chest.
In a First Class lever, the fulcrum is between the effort and the load.
