In the event of danger.
Citaro

In the event of danger.

Before a crash occurs, the driver must respond quickly to avoid an accident. The Citaro provides assistance with its directionally stable suspension and smooth steering, which result from the independent suspension on the front axle.

There is particular emphasis on driver safety in the new Citaro. The UNECE-R 29 Directive applicable to trucks, which has defined the survival space for the driver in a head-on collision in a truck since 1975, has been voluntarily adopted as the standard for the Citaro. Compliance with UNECE-R 29 is checked through a pendulum impact test.

Protection in the event of a head-on collision based on the UNECE-R 29 standard, unparalleled amongst urban regular-service buses, as well as the even stiffer structure of the frame, increases passive safety.

The new driver protection door can protect the driver from unexpected attacks. Depending on the intended deployment of the vehicle and the degree of protection desired, there are four modular constructions available.

The Citaro is equipped as standard with a fire detection system in the engine compartment which monitors the prevailing temperatures there. If the preset value of 160 °C is exceeded, the pressurised detection line breaks and warns the driver of the imminent danger by means of an audible alarm and visually in the driver's display with the message "Engine compartment fire detected".

A malfunction affecting the vehicle's operational readiness as well as an activation of the system, e.g. during a period of the bus being parked unsupervised, the driver is informed via the message "Failure of fire detection system" also being shown in the display.

If a temperature of approximately 160 °C is exceeded, the driver sees an alarm in the driver's display as well as the message "Engine compartment fire". Additionally, an acoustic warning tone is emitted and the extinguishing process initiated automatically.

In the case of a fire, the pressurised detection line (Firetrace) breaks and sprays an extinguishing mixture made of water, engine coolant and a special additive via a series of nozzles around the entire engine compartment. The water mist evaporates as a result of the high temperatures and displaces the oxygen. The engine compartment is thus cooled rapidly, the fire extinguished immediately and re-ignition of the fire prevented. 

Advantages.

  • Low scope of repairs after the system is triggered
  • Fine water mist reduces temperatures are extinguishes the fire immediately
  • Film-forming substances make it more difficult for the fire to re-ignite
  • Not harmful to humans, engine and systems
  • Environmentally friendly extinguishing substance with anti-freeze properties down as low as -35 °C
  • Automatic triggering at high temperatures (over 160 °C or in the case of fire)
  • The system is guaranteed to function in any installation position

In case of imminent danger, the correct reaction of the driver is just as important as the technical equipment of the vehicle. OMNIplus safety training courses provide the ideal basis. They focus among other things on practical familiarity with the behaviour of the vehicle in critical situations.

Difficult passengers can also present a hazard, which is why OMNIplus offers special communication training. The course covers an extensive range of aspects of interpersonal communication and individually addresses special cases in occupational practice.
