I picked up an interesting leaflet at the Hazards conference. It covers the problems of people using the wrong materials from drums and sacks. It points out that this can be because they labeled incorrectly, but usually because the person does not identify the correct drum or sack. There are many reasons for this, but poor labeling, easily confused materials names and badly organised storage are significant contributors.
The leaflet includes descriptions of 11 incidents and then goes on to discuss possible solutions. It should be really useful when dealing with situations where errors in selecting materials are possible providing a benchmark against which to judge the companies risk controls.
