Nearly 54 million cars and trucks in the United States are equipped with driver side air bags located in the center of the steering wheel. 24 million also have a passenger-side device located in the dashboard. Air bags are designed to protect against sudden, fierce frontal highway impacts.
Five years ago evidence of serious air-bag injuries began to surface. Drivers in minor fender benders suffered severe eye and ear injuries, broken bones and third-degree burns from the force of the inflating bags. In December 1991 the National Highway Traffic Safety Administration (NHTSA) advised parents to avoid putting rear-facing infant sets in front of air bags, acknowledging that the force of the explosive bag could harm infants, whose heads were only inches away from the devices.

Last October it was determined that all children 12 and under were more susceptible to injury and death than adults; their more fragile bodies were seated lower, increasing the impact of the air bag to the head area. In addition, more children were not properly restrained or were out of position when the air bag inflated. On November 22, 1996, after nearly 60 deaths and thousands of injuries were attributed to the devices, the NHTSA mandated improved labels for all new vehicles, warning of the risk to children under 13. Despite these problems, officials stress the overall effectiveness of these devices. “All in all, air bags work well and are responsible for an 11 percent reduction in driver fatalities,” says NHTSA Administrator Dr. Ricardo Martinez. “First and foremost, make sure you’re properly buckled up before getting on the road,” says Brain O’Neill, president of the Insurance Institute for Highway Safety. Keep in mind how close you sit to an air bag. Push seats as far back as possible, remaining just close enough to control the pedals. Your face and torso should be at least ten to 12 inches from the steering column. “It’s not a bad idea actually to measure the distance with a ruler to be sure.” adds O’Neill.

Adjustable steering wheels should be pointed toward the chest rather than the head to prevent inflating bag from damaging the face or neck. Also, position hands at nine o’clock and three o’clock on the wheel to keep your arms away from an opening air bag.
Pregnant women in particular should keep their abdomen as distant from the air bag as possible. In the final trimester, women should point adjustable steering wheels upward, away from their fetus.
Perhaps most important, children 12 and under should always ride in the back seat, buckled up.

短文大意

在美国有七千八百万汽车和卡车上装有防护气囊，用来缓解猛烈的正面冲击。五年前严重的防护气囊事故开始出现，去年十月测定出 12 岁以下的孩子比成人更容易伤亡， 1996 年 11 月近 60 人死亡几千人受伤都归于防护气囊装置。但总的说来，这种装置还是有用的，使司机死亡率减少了 11% 。所以公路安全保险部门告诫人们上路之前一定要系好安全带，不要坐得太靠前，只要刚好能踩着油门就可以了。可调方向盘应对准胸前而不是头部，孕妇尤其要近可能使腹部远离防护气囊， 12 岁以下的孩子应该系上安全带坐在后座。
