Hi,
Thought it was at least 3 immediate, underlying and root causes.

Unsafe Act - Unsafe Condition?

Have a look at a well knowm search engine and look up Heinrick, Bird and Loftus 'Domino'

Basically a) the immediate cause b) the underlying cause(s). This is taking a simplistic view as some causal factors are quite complex, whereas their could be just one cause - the immediate cause.

what's your definition of 'accident'?
I can think of one popular definition that would make the answer to your question self-evident.

a) A person and a source of hazardous energy exist in a situation where they COULD interact

b) "Something" causes them to interact

Might not be definitive but without those 2 conditions there's no accident

David - does there really have to be a person to be an accident?

Are you indicating that without a person it would be a (dangerous) occurrence?

I just presumed we were talking about an accident that occurred to a person that's all.

Suppose it depends on the definition of "accident" for the purposes of the question.

bit of a generic question really..

Maybe a misinterpretation but think about it .. some times there are more than 2 events leading to an accident that cause it...

unsafe condition, unsafe act, lack of planning, lack of training etc etc..

think of F E Birds accident triangle..

surely not so much an uncontrollable event as an event that is controlled? - very big difference

1. There's a big hole in the ground
2. Someone falls in it

Sorry being a bit mischievous :-) but on a slightly different tack, how about, there must be a hazard and the consequence of the hazard is realised. It's not perfect by any means.

I still like the falling in the hole idea!
