I am pretty sure that, because service technician's services are sold to customer's as "experts", we are legally expected to be -experts-. but as an expert we are also expected to know just exactly where our expertise ends, and be willing to acknowledge just exactly where that end is.
that said, swoop, I _know_ that you receive safety education as part and parcel of the factory service training we all receive, we just don't even think about it any more. it usually happens in the 1st few minutes of the class, right after they make sure you know where the bathrooms are, when break time is, and right after they tell you what they are going to tell you. you just consider it as background for what the class is about. when you took your LPG fuels system class, they talked about the properties of LPG fuel, and included safety around LPG fuel as part of that discussion.
As far as the regulations about forklift service personal operating powered industrial trucks in multiple locations, [OSHA {29CFR1910.178} specifies training to be 'site specific'] this is an area most dealerships expect to be covered by the service and or sales department having done a site assessment/inventory as part of the "due diligence" in getting to know a new customer and what they have, along with the service tech having a pretty good knowledge about when and where injuries happen, and what is "energy" (that must be 'locked out' before work goes on).
Forklift repair still is one heck of a dangerous and injury filled job, and takes full time 'situational awareness' [knowing what is going on around you all the time] in order to be able to say; 'everyone goes home safe today' which I would wish we could say every day.
