Bus Fire Extinguishing

Bus fire extinguishing is one of the most critical measures to ensure passenger and driver safety. With the increasing use of vehicles, especially in urban and intercity transportation, precautions to be taken against fire risk in buses have gained more importance. In this article, the importance, technologies, standards and application examples of fire extinguishing systems in buses will be discussed in detail.

Main Causes of Bus Fires

Fires in buses usually originate from engine compartment, electrical systems or fuel leaks. The main causes of fires are listed below:

• Short circuits in electrical cables
• Fuel leaks
• Overheated engine parts
• Excessive friction in brake systems

The Importance of Fire Extinguishing Systems in Buses

Bus fire extinguishing systems are automatically activated when a fire starts and control the fire before it grows. These systems are necessary to both protect human life and minimize material damage.

Saves Lives

A possible fire on a bus must be brought under control within a limited time frame, limited to the time it takes for passengers to evacuate. Automatic fire extinguishing systems provide life safety by gaining this time.

Reduces Material Loss

A bus burning is not limited to the cost of the vehicle; it also causes great damage to the company image, operational continuity and insurance costs.

Types of Systems Used

The fire extinguishing systems commonly preferred in buses are as follows:

Aerosol Fire Extinguishing Systems

Works with aerosol particles consisting of chemical components. It is not electrically conductive and environmentally friendly. It takes up less space than compressed gas systems.

Water Mist Systems

Provides effective cooling by creating micro droplets. Compatible with electrical components. It is especially preferred in engine compartment fires.

Certification and Standards

The compliance of bus fire extinguishing systems with international standards is of great importance. It is recommended to use systems that comply with the following standards:

• ECE R107: Determines mandatory tests for fire safety in passenger buses.
• ISO 17840: Vehicle provides information for emergency response guidelines in case of fires.
• ISO 15779: Includes testing and assembly requirements for aerosol systems.
• Detailed information about the ISO 15779 standard

Öe Sample Applications

Alas Fire automatic fire extinguishing systems are successfully used in many bus fleets.  Finally, the fire risk has been minimized with the systems integrated into the Eskişehir Metropolitan Municipality fleet. In addition, 75 aerosol fire extinguishing sets sent to bus manufacturers in Egypt prove the international validity and reliability of the system.   Bus fire extinguishing systems are of great importance in terms of both human life and economic value. Especially thanks to new generation systems such as aerosol and water mist, fires can be controlled more effectively and safely.
