• Accidentally wired 120v to some motor drives, frying their Run input

• Dropped a chunk of pipe on fresh tile

• Almost killed myself with live wires on multiple occasions, everywhere from 480v to 28,800v

• Wasn't my fault specifically, but pulled in $50,000 of the wrong wire that all had to be removed and scrapped

• Racked up 94 "excessive speeding" events over three days in my company truck

• Almost tipped a scissor lift on several occasions
