My earlier response to this E-Stop thread reminded me of another BITE (Believe It, True Event) or GOTCHA story:
An HPI plant was subjected to numerous unwarranted (false) trips. The peculiarity was that the trips aways occurred on tuesday... at about the 2pm shift change.
One tuesday the plant tripped resulting in a $1MM, 400-foot flame on a 400-foot flare stack (airlines used it as a directional beacon...
often). I ran (in those days I could) into the control room and started my "investigation." Almost immediately, a cleaning woman asked me...
"Mr. Corso, why is there all this confusion every time I come to work?" I asked "How often to you come here?" She responded... "Every Tuesday...
at shift change!" In my best investigative voice I then asked "What do you do when you enter the control room?" She announced, proudly... "I push the doorbell!"
The "doorbell" was, of course, the Emergency Trip pushbtton. It was a large red-colored, mushroom head pushbutton. Its nameplate was engraved
"Emergency Trip". And every one knew its function. Everyone, that is, except the cleaning lady... she couldn't read english!
Any one else with a BITE story?
