Each company has their own written health & safety procedures which all staff members have to make sure they read and understand. The idea behind this “video supplement” is not to replace the procedure, but allows the employees to get a visual “overview” of the policy and helps them remember the key points.
A simple multiple choice question can be added as an additional flash layer at the end of the video, and that would allow you to track if each employee is taking on board the information or not.
I will add the multiple choice question at a later date once I have tested a few different options I have available to me.
