I recently outfitted a crew to build scaffold in preparation for an upcoming turnaround at our plant. Among the tools requested were canvas buckets for manually hauling material and tools up and down scaffolds. In sourcing these I went through a reliable well established industrial supplier with a know brand. I ordered bags rated for 100 lbs which above the maximum load for manual hoisting permissible on our site.
Several days after arrival on site one of these bags failed with a 27 lb load in it. Nobody was hurt but it could have easily turned out differently. We immediately pulled all bags from use. In investigating it was discovered that when used outside in winter conditions that the plastic parts of the bag bottoms become brittle. No temperature restrictions were offered in any documentation related to these bags and these tools were being used for the purpose they were designed for.
I feel awful that a decision I made put people at risk. Is there some aspect of due diligence in tool selection that a reasonable engineer would have been expected to take that I had missed?
