We recently had an incident where a 53' trailer floor gave way while one of our forklift drivers was on the trailer. Fortunately the driver was not injured. After an investigation, it appears that several of the rivets attaching the crossbeams had deteriorated and allowed a couple crossbeams to break away under the weight of the forklift. Surprisingly, the trailer had just been inspected 2 weeks ago and no deficiencies were noted. As a result, we have implemented a procedure where by the forklift driver does a walk around the outside of the trailer prior to unloading it. I found a checklist from OSHA with respect to items to look at that we have incoporated. Our drivers already checked the interior as they unload to look for any damage, but I figured an exterior review might indicate potential issues they couldn't see until it was possibly too late. Has anyone had a similiar experience or know of a better method ?

Thanks
