Fatal Lack of Error Proofing
A safety precaution put in place for a thrill ride after a fatal accident three years ago wasn’t being followed when a worker was killed on the same ride, an amusement park official acknowledged Saturday.
The ride’s new operator, his view apparently blocked by a high back on the ride’s seat, started the Mind Scrambler while Garin was kneeling on a seat bench, Spano said.
Tartaglia said the operator noticed Garin and shut the ride down within 20 seconds, but she had already been thrown to her death. Only one attendant was on duty when Garin died, he said, despite a safety measure put in place after a 7-year-old girl died in 2004.
Not a lot of details in the article, but it’s a shame that the process (or lack thereof) allowed the ride to be started at a dangerous time. The employees were, I’m sure, told to “be careful” but the ride wasn’t error proofed, and a young woman died, the 21 year old worker.
It seems like rides like this should have dual controls, dual switches that BOTH workers have to turn at the same time. This would help ensure that neither of them were in a dangerous zone. There should be some sort of “lock out” strategy or methodology, as would be very common in just about any U.S. factory today (at least if people are following the rules).
