There were 1,557,500 fires in the United States. A decrease of 5.2% from the year before. Of these:
|
| Steel continues to be the dominant material in automobiles because of the strength it provides. It accounts for more than half of the total weight in cars made over the past two decades. |
| Polyvinyl chloride or 'PVC' is a modern synthetic material and an important member of the extensive polymers 'family'. In automotive applications it is the second most important polymer (after polypropylene). |
| Ten years ago, about 150 pounds of plastics were on the average American vehicle. Today, more than 250 pounds are being used. More than 320 pounds of plastic will be used on 2010 cars. Also, every pound of plastic on an automobile replaces two to three pounds of other materials. |
| Aluminum is the third most-used material in automobiles. |
| Automakers are packing cars and trucks with new devices to increase safety for motorists, such as airbags that can fire off twice and are located in doors, roofs, dash boards, and seats. But the same equipment poses dangers to rescuers, who often are not aware the hazards even exist. |
| "Pre-tensioning" seat belts, which use a charge of gunpowder to yank against an occupant during impact, can explode in the hands of a firefighter working to cut someone free. A retractable rollbar that springs up behind the seats in some convertibles can cause serious injuries to an unsuspecting paramedic. Metal detonators tucked into rooftops to inflate side curtain airbags can go off like missiles if cut into by rescuers, firing into the cabin of the vehicle. |
| Emergency workers are used to dealing with the standard hazards of gas tanks and 12-volt batteries, but technology is changing so quickly that many cannot keep up with what's on the street, from cars with as many as a dozen airbags to gas-electric hybrid vehicles with batteries powerful enough to electrocute a person. |
| It's not just safety devices that have emergency workers concerned. New fuel or engine technologies also pose risks, such as cars with explosive propane gas tanks or powerful electric batteries. |
| In today's cars and light trucks, batteries are appearing in wheel wells, under the rear seat and even in the trunk. Also a back-up power supply known as a capacitor is being used. Unfortunately, these devices can sometimes hold a back-up charge for up to 30 minutes. |
| Laptop computers, DVD players, or even MP3-type units plugged into power ports on today's cars will supply power to air bags even after the battery has been disconnected. |
| Gas struts are used to hold hoods and hatchbacks in the open position. They also are common in bumper locations. These devices have the potential to be launched from the vehicle with explosive force in fire situations. |
| A Montgomery County firefighter, noticed something strange recently when he approached a wrecked car. Though the engine was shut off, the injured driver kept her foot on the brake. It turned out the car was still running on silent electric power and could have surged forward, hitting rescuers or bystanders. |
| In addition to running silently, the battery in a hybrid packs enough voltage to kill a person -- more than 650 volts AC in some hybrids, compared to 12 volts in the standard car battery. |
| The average vehicle may come with 4-6 airbags, standard or optional, including inexpensive vehicles. BMW's new 7, 6 and 5 Series can come equipped with 10-12 airbags, including knee airbags in the lower dash. Approximately 70% of new vehicles have side impact airbags or side curtain airbags. New safety innovations will change the way all first responders will work around these vehicles. |
| Dozens of firemen have been hurt by airbags that did not deploy during the crash but did explode during the rescue. It is especially dangerous for a rescue worker to get between an airbag and the patient. Anything from static electricity to emergency cutting equipment can set off an undeployed air bag. |
| How do you know where airbags and sensors are located on the more than 800 airbag equipped vehicles on our roads today? Without regular safety training and the use of reference materials you are literally entering vehicles blindfolded. |
