I do not believe that there is a specified expiration date for in-house trainers, although there should be. Many of these so-called in-house trainers do not train on a regular basis, and tend to forget alot of what they learnt from the trainer when they took the course. Then you get the bad, training the weak, and that does not instill much confidence, in me, anyhow.

So, at least north of your border, there is no expiration on their training, but updates wouldn't be a bad idea.

Forklift certification can mean a couple of things. 1, a pre-shift inspection done by the operator. 2, An annual check-up sort of speak which is mandatory whereby the tech does a complete once over, and repairs any faults before placing a sticker , usually on the mast, that is signed off, has a req. #, and the date that the truck was inspected, and therefore, 'certified'.

Hope this answers your questions, rather briefly.
