The San Francisco Chronicle’s site has an update on the GGB barrier debate. Unfortunately, most people don’t want any kind of barrier at all. However, of the design options, the net is proving to be the most popular. Likely because it doesn’t affect the aesthetics of the bridge by much and it is still considered a suicide prevention mechanism.
I’d initially cited concerns about how jumpers would be pulled out of the net. Rachael Gordon, the Chronicle’s staff writer, got chief engineer Denis Mulligan to provide an answer:
For starters, he said, once someone jumps over the Art Deco span’s 4-foot railing, it could take rescuers several hours to get to the scene to retrieve the person from the net, which essentially would envelop the person and make it difficult but still possible to clamber out.
“It wouldn’t be like a trampoline, that once you jump onto, it would be easy to jump off,” Mulligan said. But, he added, “If you’re very agile, very strong and focused, you may be able to climb out.”
I hope it’s as hard to climb out of as Mulligan cites. Just the wait to be rescued alone might get jumpers to think twice about trying again. But here’s the process in more detail:
During a rescue operation from the net, authorities would shut down a lane of traffic. A specialized vehicle, called a “snooper” truck, would be brought in. Outfitted with a mechanical arm similar to a cherry picker used by utility crews, two specially trained rescue workers would be lowered down to the net in a bucket to pull the person out.
Authorities said they would have to convince pranksters and daredevils that jumping into the net would not be a pleasant experience.
“It would hurt,” Mulligan said of the 20-foot drop into a net made out of marine-grade stainless steel coated in plastic.
This article also uses another bridge — a former suicide hotspot — as an example to show that suicides can be prevented.
In Switzerland, researchers found that just the presence of the net stopped people from even trying to jump off the Munster Terrace, a medieval cathedral located in the old section of Bern, from which two or three people had been leaping to their deaths every year. They also found that the net did not shift suicides to other locations.
And that the implementation of barriers in other places have also proven successful:
Other well-known jump spots, among them the Eiffel Tower in Paris and the Empire State Building in New York City, were long ago outfitted with suicide barriers. Like the net attached to the Gothic cathedral in Bern, studies have shown them effective in thwarting impulsive suicide attempts.
I’m not so idealistic to think barriers will keep suicidal people from committing suicide. Rather, I think they’re worth erecting for “thwarting impulsive suicide attempts.” Who knows how many people are still alive as a result?
The general public is welcome to vote for a barrier on the Golden Gate Bridge and provide additional comments (ie, you don’t need to be from California or San Francisco). Visit the Golden Gate Bridge Suicide Deterrent Barrier site to make your opinion known on this issue.
