Sturdier cars can hinder crash rescue operations

A Hillsborough County firefighter opens up a car's door during a "Jaws of Life" demonstration recently in Tampa, Fla. Today's cars save lives by cocooning motorists in reinforced alloys, impact-absorbing crumple zones and as many as a dozen air bags. But rescue officials and experts from around the United States say the new technology is also hindering extrication of injured people.

— Capt. Clint Roberts makes his living cutting accident victims out of hideously mangled vehicles, but even he could hardly believe it when two people in a 2007 midsize car survived a head-on crash with a full-sized pickup last year.

The Ford Fusion's reinforced steel construction probably saved the lives of the 18-year-old driver and his 16-year-old passenger. But Roberts said it gave his Hillsborough County Fire Rescue crew fits as they tried to free them last November.

Because hydraulic cutters couldn't shear the roof posts, rescue workers had to turn to heavy-duty electric saws, replacing blade after blade as they dulled on the rugged material.

"It was just beating the snot out of the tools," adding minutes and delaying medical treatment, Roberts said.

There is no question that today's cars save lives by cocooning motorists in reinforced alloys, impact-absorbing crumple zones and as many as a dozen air bags.

But in interviews with The Associated Press, rescue officials and experts from around the United States said the new technology is also hindering extrication of injured people, increasingly forcing crews to work deeper into the critical "golden hour" between accident and treatment by emergency room doctors. On many 2005 and later cars, an extrication that once took 10 or 15 minutes can now take twice that or longer.

To catch up, counties and cities are spending tens of thousands of dollars - if they can afford it - to buy more powerful equipment that can cut through newer cars' reinforced steel and the lighter, tougher exotic metals used in roofs, posts and doors.

Then there are obstacles that endanger rescuers' safety. Pressurized gas canisters that inflate air bags can explode if pierced by cutting tools. Rescuers can be blown from cars when air bags suddenly inflate. Hidden battery cables in hybrid cars can deliver a powerful shock.

To protect themselves, workers now have to peel away the ceiling and interior plastic to see what's underneath before they can even start cutting.

Experts cannot say for certain whether the delays in getting these victims to the hospital have resulted in people dying. But that's the fear.

"We build more fire stations, we make faster fire trucks, we've got helicopters to get you to the hospital," said Roberts, an expert who teaches extrication to colleagues around Florida. "But what's slowing us down are these vehicles that are harder for us to get into."

The flip side, of course, is that more people are surviving horrific crashes that would have killed them just a few years ago.

The Fusion's passenger, for example, was hurt but conscious and joking with Roberts as the crew worked to get him out. The driver of the other vehicle involved - a 2001 Ford F-150 pickup - was dead at the scene.

With about three people hurt in car crashes every minute in the United States, National Highway Traffic Safety Administration spokesman Rae Tyson said he is comfortable with the trade-off. Rescue workers, he said, will have to work harder to keep up with technology, just like everybody else.

"The fatality rate for passenger vehicles is the lowest in history," Tyson said. "That, to me, is a pretty good news story."

There isn't a "golden hour" if everyone is not alive. Way to go car manufacturers.
