Example Fault Tree- Signal machine - pieman31 - 16-02-2012

Hi All,

I had to knock up a fault tree for a paper I'm writing at work. I'll share an early version here as an exmaple, be it good or bad, to stimulate your thoughts and possibly fuel a discussion...

To provide a bit of context, the fault tree represents some failure modes applicable to a Westinghouse Signal Machine, which, is used to operate Semaphore Signal Arms in both upper and lower quadrant arrangements.

In terms of the exam, granted it took me a while to draw on a computer but the original draft took about 25 minutes (too illegible for use on here!) given that I had a full set of FMEA to work from.

Hope you find it useful.....

Cheers.
