Oh an interesting line here - mistakes ? can tell you a few ones that would well make yer eyes water.
When doing my time I helped out with a rewire at a factory - putting in a new distboard and connecting up some plant. Anyways usual saturday afternoon blast get it done and then out for the evening - only this time it was a blast literally. One of the guys doing it dropped an adjustable spanner unlucky for him if fell onto the busbars took out two phases. Now I jumped as the bang was like nothing I had heard before. Young sparkie not a lot of experiance. Anyways it took out the main fuses on two phases. What happened next ? Yep the back up generator started - mains fail detected and the genny breaker closed - spanner was well and truly wasted - The second bang wasnt as loud but well we all raced to try and shut the diesel down.... Dont think anyone would have heard it woith all the panting that was goin on.
I heard about a maintenance crew working on a genset someplace near vancouver - had just drained down the oil and were out getting a cup of coffee when they had a mains fail - that old engine started and run for a few minutes before it siezed up..... That must have been an expensive fix. Try explaining that one to your boss....
Oh and a could it get any worse story, A trucker out on I 40 gets a slow puncture - tyre heats up and starts to smoke. Pulls over in the rain parks under a bridge for shelter. Tries to call on the mobile to let boss know tyre is kaput and needs tyre repair cant get signal under bridge walks up shoulder to get signal on phone calls boss and tells him, during concersation turns to look at truck and sees tyre on fire - hes loaded up with HAZMAT so he aint going back for the fire extinguisher - starts to run back up the road to stop traffic, wet road gut running about waving arms ? Yep tailenders all over. Meanwhile truck has burst into flames and then the bridge collapses with the heat.
Id be suprised if he still had a job after all of this....
