Lots of committees already require that members demonstrate how to properly use their cert-required tools during the training course, in order to pass the course and receive certification. For example, Woodshop Basics involves using all of the woodshop tools in the safe way discussed by the trainer, while the trainer supervises.
The lift course as it was when I took it was very hands-off, only the trainer using the tool and pointing at things. Since it’s obvious that a new lift course would be necessary for a telescoping arm lift, it would probably be beneficial to restructure the training so each student has to go through the process of safely lifting and lowering a vehicle under trainer supervision so they can get certified. It might also help to have pictures on hand to ensure everyone knows what they’re looking for as far as safe lift points on their own vehicles.
And then, obviously lock down the lift’s power feed with an RFID scanner so only certed users can even think about playing mechanic.
