Dear friends,
There is the question as to how illusion can cause accidents?
Here is my brief answer.
Perception is the midway process between sensing and behavior. Perception is the process by which we understand the stimulus, interpret its meaning and modify our behavior. It is a way of interpreting stimulus which is determined largely by past experience.
Illusion is a false perception.
With a machine out put depends only up on input and it is predictable. However with a man the input – stimulus remaining the same behavior may differ. This is because perception of men differs –from person to person, time to time, and condition to condition. This is important in accident prevention.
For illusion there are very many causes. The energy available for sensing such as radiation for seeing, mechanical for hearing and touching, chemical for smelling and tasting. Cognizance also plays an important role in perception/illusion.
A man in dim light may see a snake on the aisle and jump to fall in the ditch. Another with a torch may see the same as a piece of rope and kick it or remove it the side
An illusion may cause unsafe behavior. Unsafe behavior can cause accidents. This is the relation illusion has with accident prevention.

Dear Sir
Thanks for the simplest explanation...
Do you have any case srudty of Industrial Accident in which the illusion comes as a contributory reason? If so please share the same for more understanidng of the concept?
Suppose after a particular Incident Investigation it came to know that illusion was one of the contributory reasons of that incidnet, what recommendation we must suggest to avoid the re-occurance? How we can ensure the parrellel implemetation of this particular recommendations among all the working crew as "perception of men differs –from person to person, time to time, and condition to condition"
I would like to share one of the incident in which this illusion may be one of the contributory reason. I think so. Need clarrification.
One person was engaged in pocking of materail in hopper through a pocking hole of dia 100mm... During this work suddenly few material flesh out through the opening... By seeing this he thought the amount of material fleshed is high and jumped from the platform and got injury on foot... He not think that what will be the maximum materail can flesh through a 100mm hole...
Please give your valuable comment on the above incident... What's the reasons you identify and what should be the suggestions we must give to avoid recurrance of such incidents?

I do not think it is an illution. 1) the worker has not been given proper training in operation of the machine. 2) The feed table is so high placed proper guarding should have been made for the worker to jumb and injured. 3) The worker I persume is in 'line of fire' any material back fall would certainly create some anxity to worker becuse of persumption / or by earlier experience. When any hopper feeding where likely hood of back fall, should have a operator controlled switch near to his work place to stop such occurance.
The above based on the details provided by you above. But in actual observation there are other areas like operator is short / tall for the feed table and hopper,
Best way is to observe the operation for ten minutes, and you may find lot of unsafe behoviours / unsafe conditions

Dear all,
I copy the question from Mr. Dipils write up.
**How we can ensure the parrellel implemetation of this particular recommendations among all the working crew as "perception of men differs –from person to person, time to time, and condition to condition**
Counselling and training has been identified as a tool to bring different peron of a work area on the same level so that their reaction to a perticular situation is more or less of the same pattern. Although achieving the ideal condition were everyone reacts in a similar way is not possible, but the training can help a lot to bridge the differences and also develope the skill where people can react in the desired safe manner.
Best Regards.

Thanks a lot for your reply to my query... Surely counciling and training is the tool which we can use to change the behaviour of a person...
In the starting thread Keshav Pillai pointed out one example for illusion that a person sees a piece of rope and thought that it's snake and jump to ditch causing accident... In this case can this counciling and trainig will help?... Can this assure that same wrong perception by the same person will not repeat?... When comes to this particular example what my judgement is this happened due to less visibility and we must give recommendation for increasing the illumination... May be illusion can be one of the contributory cause which we can't fully remove... The root cause will be lack of illumination...
Hope to get more views on illusion from the members... Once again requesting to all if anyone having a case study of industrial accident in which illusion comes as a cause please share the same...
