Guidelines for Rescue Services, smart, 2006 Page 5 Dear reader, One of DaimlerChrysler's top priorities has tradi
tionally been to guarantee the highest possible standards of safety. This emphasis on safety is especially pronounced also in vehicles of the "smart" brand, the ultra
compact line within the Mercedes Car Group. Our comprehensive safety concept also extends to providing you, the rescue crews, with specific infor
mation about our vehicles and their safety systems. The top priority of the rescue crew is to save lives. You must be able to gain access to the accident victims as quickly as possible without exposing yourselves or the victims to additional dangers. This is why we are providing you, the specialist, with this vital and reliable information. The object is to foster familiarity with the structures and safety systems in the individual vehicle versions and various model series. The automobiles manufactured by smart differ from conventional cars in a number of respects. This guideline manual responds to this fact by serving up information compiled especially for the use of rescue personnel. It describes the relevant technical features incorporated in the smart city coupé, smart roadster and smart forfour model series. Because the concept behind the sport
oriented roadster has been largely derived from the city coupé, the two share a number of common features: • Steel body with plastic paneling • Aluminum doors • Roof concepts • Location of drive unit and tank etc. This guide is intended to assist you in performing the duties that you usually carry out while working under considerable stress. So that every action will be carried out with precision when the time comes, this advance information booklet must cover all vital points as they relate to specific scenarios. We hope that this guide can be judged a success in this respect. At the same time, we would greatly appre
ciate any suggestions and feedback you can offer based on your own practical experience. smart gmbh Technical Communication (E/PD) in collaboration with DaimlerChrysler AG Parts Engineering and Technical Information (GSP/TI) Downloaded from www.Manualslib.com manuals search engine

Proper casualty rescue

Forfour_454_2006_Maintenance_Guidelines_44p.pdf · p. 8 · Applies to: 454

Page 6 Guidelines for Rescue Services, smart, 2006 Overview Whereas formerly priority was given to quickly rescuing the trapped casualty from his predicament, the primary concern nowadays is medical and psychological assistance. The aim of this is to prepare the casualty as well as possible for the rescue work. The medical and rescue personnel can then work in concert to free the casualty from the vehicle. The most urgent immediate measures at the scene of the accident are: • Maintaining or restoring the vital functions (respiration/circulation) • Keeping the respiratory passages clear and rectifying any breathing difficulties • Assessing shock and initiating measures to stabilize the casualty • Rendering psychological support to the casualty • Treating life
threatening injuries • Stopping major bleeding • Immobilizing certain body parts Immobilizing the neck As the head often experiences extreme movements in traffic accidents, there is an increased risk of spinal injury in the neck region. To prevent further damage to the cervical vertebrae, it is essential to immobilize the neck before any further rescue action is undertaken. The most common method of immobilization is to use a cervical collar ("Stifnek"). This is a plastic collar which is placed around the neck and closed with a velcro fastener. If access to the casualty is difficult, the head restraint can be removed first before fitting the cervical collar. i The main priority is to render medical and psychological aid to the casualty! i The safety of the medical and rescue crews themselves should not be neglected: • Wear protective clothing • Wear eye protection • Wear protective mouth mask • Secure the accident vehicle i The head restraints should only be cut away in exceptional cases! • Cutting the head restraints away exposes the casualty to additional movements • The head restraint can no longer be used to stabilize the casualty's head • Cutting away the head restraints produces sharp edges Downloaded from www.Manualslib.com manuals search engine

Extinguishing vehicle fires

Forfour_454_2006_Maintenance_Guidelines_44p.pdf · p. 9 · Applies to: 454

Guidelines for Rescue Services, smart, 2006 Page 7 Overview Extinguish fires in accordance with the guidelines of the professional fire services! Body: Magnesium is increasingly being used in safety
relevant reinforcement structures in the body. For example, the instrument panel structure in smart vehicles is made of magnesium. When combatting fires within the vehicle's inte
rior and in the area around the instrument panel, it is therefore vital to observe the special instructions issued by the fire department with respect to the materials employed in these areas! i Magnesium is a Class D flammable material according to the EN2 European Standard on "flammable materials of various kinds". Restraint systems: If a fire breaks out inside the vehicle, it may acti
vate any untriggered front airbags, sidebags and windowbags or the pyrotechnical emergency tensioning retractors. Gas generators are designed to ignite as soon as the temperature inside the gas generator reaches 160
180° C.In such cases the ignition squib and the solid fuel burn without destroying the gas generator. During combustion a specific volume of gas is released at a specific pressure. i When the front airbags, sidebags, windowbags and emergency tensioning retractors are triggered, controlled combustion takes place. The components do not explode. Windowbags The gas generators of the windowbags are filled not with solid fuel, but with compressed gas. i The compressed gas generators of the windowbags must not be cut, as otherwise the compressed gas may suddenly escape! i Before cutting the corresponding body panels the inner paneling of the A, B or C
pillars must be removed using a suitable tool and the exact installation location of the gas generators determined! Downloaded from www.Manualslib.com manuals search engine

Page 8 Guidelines for Rescue Services, smart, 2006 Rescue On arrival at the scene of the accident, the first priority of the rescue crew should be to ascertain and assess the condition of the casualties. If possible, proper rescue of the occupants should only be undertaken when the vehicle has been suffi
ciently secured and, if possible, in consultation with the emergency physician (does not apply to emer
gency crash rescue!). Trapped casualties are in direct physical contact with the accident vehicle. Therefore the supports must guarantee that the vehicle cannot move during the subsequent rescue operations. The support must remain secure throughout the entire duration of the rescue operation and must be able to withstand the use of hydraulic equipment. When using sliding support blocks to support the vehicle, the air can be let out of the tires after the blocks have been slipped underneath. a Risk of injury Action Unintended movements of the bodywork during rescue operations may cause further injury to the casualties. To prevent dangerous movements from occurring while rescuing the casualties, the vehicles involved should first be secured. P00.60
2034
00 i The vehicle must be supported with wooden planks, sliding support blocks or similar in order to ensure a gentle and smooth rescue! When positioning the sliding support blocks, care must be taken to ensure that subsequent rescue actions are not impeded. i Never use the vehicle's tow eyes to secure or recover the car. The strength of the body in the area of the towing eyes may not be sufficient following an accident. Downloaded from www.Manualslib.com manuals search engine

Removing the windows

Forfour_454_2006_Maintenance_Guidelines_44p.pdf · p. 12 · Applies to: 454

Page 10 Guidelines for Rescue Services, smart, 2006 Rescue Windows in parts adjacent to those being worked on must always be removed before using hydraulic tools. This applies above all to the windows in the doors. If the windows are not removed, they will be subjected to considerable pressure together with the associated body panels, e.g. when opening the doors with a spreader. At a certain compressive force the windows will be unable to withstand the pressure and will burst suddenly and violently. The ejected fragments can inflict injuries. Vehicles in the smart model series are generally equipped with two types of safety glass. The windshield and door windows are made of lami
nated safety glass (VSG), the rear and side windows on almost all vehicle are made of single
pane safety glass (ESG). a Risk of injury Action Work on windows and glass roofs may produce glass splinters which can cause injuries to the occupants and rescuers. Cover the occupants before commencing work, preferably with a transparent sheet. Wear protective clothing, safety glasses and a protective mouth mask. a Risk of injury Action Always remove the windows when working on adja
cent components. Windows may shatter, throwing out tiny, sharp glass particles which may cause injuries to the occupants and rescuers.

00 5 Windowbag 6 Gas generator a Risk of injury Action In contrast to the other airbag units, the gas generators of the windowbags do not contain solid fuel, but are filled with highly
compressed gas and must not be cut! If a gas generator bursts, and sharp
edged parts may be ejected at high speeds, causing injuries to the occupants and the rescuers. The loud noise may result in casualties suffering a blast trauma. For this reason, we urgently recommend removing the appropriate inner paneling and checking whether and where gas generators for windowbags are installed before commencing any cutting work. Mark the installation location on the outside of the vehicle. i Of the current smart model series, only the smart forfour (model 454) is equipped with windowbags. The gas generators are located at the top in the roof frame. Downloaded from www.Manualslib.com manuals search engine

Guidelines for Rescue Services, smart, 2006 Page 31 Rescue a Risk of injury Action If using safety devices intended to protect against airbag deployments after an accident, there is a danger that these devices may be cata
pulted by the deploying airbag, presenting an additional injury hazard for casualties and rescuers alike. We advise against the use of "protective devices" that are intended to prevent a pressure buildup by piercing holes in the airbag fabric because, if the airbag is triggered, the hot ignition gases can escape unhindered and cause burns. Cover the occupants before commencing work, preferably with a transparent sheet. Wear protective clothing/safety glasses. Disconnect all batteries. If this is not possible, keep well away from undeployed airbags. Avoid heating near undeployed airbags. Do not place any objects near untriggered airbags. a Risk of injury Action From contact with the airbag during deployment, occupants may suffer slight reddening of the skin and abrasions, e.g. on the insides of the forearms or in the face.Slight irritation of the respiratory passages cannot be ruled out. The condition of the casualties must be assessed as accurately as possible, and taking these aspects into account, before deciding on further suitable precautionary measures. i The white, powdery residues left inside the vehicle after deployment of an airbag are nontoxic. They consist for the most part of talcum, which acts as a lubricant for the airbag fabric. i The triggering strategies for the supple
mental restraint systems are subject to modifi
cation if necessary, e.g. due to new findings in accident research. Downloaded from www.Manualslib.com manuals search engine

Page 32 Guidelines for Rescue Services, smart, 2006 Rescue The airbag's air sack inflates within a few milli
seconds during the collision. The air sack reaches its maximum volume in approximately 45 ms. Immediately after maximum volume is reached, the airbag starts to deflate. The gas escapes through an air hole or through the fabric and the airbag collapses (exception: windowbags). Triggered airbags that are hanging down can be pushed upwards or to the side so as to create the necessary space for the rescue action. Airbags do not need to be cut out or covered. A triggered airbag has no medical risks for the occupants or the rescue crew. In cases where the rescue or treatment of casual
ties has to be carried out within the radius of an untriggered airbag, the following points must be observed: • Switch off the ignition • Disconnect or cut the electrical lines on the battery (on both batteries in vehicles with two batteries) • Do not perform cutting work in the immediate vicinity of the airbag units concerned • If there are no occupants on the rear seats, move the front seats as far to the rear as possible Avoid overheating the area around the airbag unit, such as the steering wheel impact plate, the instrument panel on the passenger side and the door linings. If an airbag unit is heated to over 160 °C, it is likely to be triggered. Downloaded from www.Manualslib.com manuals search engine

Guidelines for Rescue Services, smart, 2006 Page 33 Rescue Seat belts The seat belt buckles can usually be opened normally after a crash. However, it is often easier to cut the belts at an easily accessible point. In this way the rescue crew do not need to lean over the casualty, which might cause further discomfort or injury. Furthermore, leaving the belt buckle fastened provides the police with evidence that the belt was being worn. Emergency tensioning retractors The emergency tensioning retractors are acti
vated in frontal collisions with a sufficiently high deceleration acting in the longitudinal direction or in rear
end collisions with a sufficiently high acceleration acting in the longitudinal direction. The emergency tensioning retractors are inte
grated into the seat belt inertia reel mechanisms. Because different activation strategies are used the retractors may therefore be triggered both when the belt is being worn and when it is not. i When the emergency tensioning retractors are activated, the belt is retracted by max. 150 mm. The retractors cannot be triggered after the battery has been disconnected. Downloaded from www.Manualslib.com manuals search engine
