Posted By prads Can someone help me in differentiating between these two typical machinery hazards? Just trying to get a convincing distinction between both. Entanglement can result in drawing in???? Regards, Prads

Posted By WDM Must admit, when I was studying this safety stuff, I always struggled to see the real difference between the use of such words - the end result is pretty similar and messy. Seems to be an exam/IOSH question with not too much relevance in the real world. I guess 'entanglement' could be argued is more to do with getting entangled around more or less any moving part - either rotaty or reciprocating or linear movement of components. Whereas 'drawing in' could be more associated with revolving parts/shafts or rollers in a machine. All rather academic - learn it for the exam and then forget it.

Posted By stephen d clarke Hi, I think entanglement is where a tie, glove, hair etc is caught and wrapped around a rotating tool or any single rotating surface. Whereas drawing-in or trapping is about getting something trapped between a moving conveyor or table or two counter-rotating parts also was called in-running nips I think. These types of mechanical hazard along with cuts, friction, puncture, crushing, impact and shear were defined in the old BS5304 and I think they are defined in its replacement EN292 along with non-mechanical hazards such as radiation, noise, chemicals etc. Steve

Posted By Pete48 Entanglement is from contact with a single rotating surface. (drill etc). Drawing in is from contact between two rotating surfaces moving in opposite directions. (gears, rollers) Nips are an example of traps and occur between fixed and moving parts. ( at the point of contact between a conveyor belt and pulley)
