Investigation abstract
Employee #1 was working with an industrial robot that takes parts from a conveyo ently Employee #1 pushed the parts against the locator switches that automatical ly activated the robot and the robot inadvertently crushed Employee #1 against t he drill press. Employee #1 died. The original interlocked gate guards had been damaged over time, removed, and not replaced. r, feeds them into a machining operation; takes the parts and inserts them into a multi-spindle drill press; and then puts them on a spray painting turntable fo r rust-proofing. Employee #1 had apparently replaced a drill bit and returned to production but, because the parts didn't properly contact locator switches on t he drill, the robot stopped. (This was a common problem.) Employee #1 apparently then reentered the robot area without locking out or hitting the "system stop" button or pushing the "hold" button. The "system stop" button can be hit earlier in the cycle before hitting "hold," and was found to override the "hold." Appar

Labels are OSHA's own, from the code dictionary published with the accident-investigation file. The raw code is shown beside each one so this page can be reconciled against OSHA's bulk data. OSHA notes that nature of injury, part of body, source of injury and accident type in this file are not coded to the Occupational Injury and Illness Classification System, and that the occupation titles are not standardised — so these values are not directly comparable with the OIICS-coded severe injury reports.
