Fire detection & fire alarm systems inheavy vehicles
- 2016
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This report summarises the work that has been conducted in a large project about fire detection and fire alarm systems in heavy vehicles. The main goal of the project has been to develop an international test standard for fire detection systems installed in engine compartments of heavy vehicles. For the purpose of defining a test method background information has been compiled regarding fire detection technologies, relevant standards and guidelines, research in the field, durability factors associated with the environment, typical fire scenarios and fire causes. In addition, numerous experiments have been performed in order to provide data to develop the test standard. A separate goal in the project has also been to provide recommendations on fire detection in bus and coach toilet compartments and driver sleeping compartments. Some of the conducted work has been published in three previous SP reports and the work not covered in these is presented in more detail in this report. However, this report summarises all work done in the project.

- Detection of fires in vehicle engine compartments is challenging. High airflows, large temperature variations, dirty environment and complicated geometries make it difficult to determine the optimal type of detection technology and adequate location of sensors. A new test method has been developed for evaluation of fire detection systems meant for engine compartments of heavy vehicles. The test method considers all typical challenges normally encountered in an engine compartment, evaluating both detection system performance and durability. Certification rules connected to the new test method will ensure high quality and high performance of certified fire detection systems, increasing fire safety of vehicles.This paper gives an outline of the new certification rules, test method and corresponding research.

New certification system for enhanced fire safety of vehicles

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- RISE has initiated and developed a certification scheme for the vehicle industry that will enable manufacturers, operators and service centres (workshops) to certify their fire risk mitigation process. The fire risk management required in the certification is a key safety element, used to identify and evaluate fire hazards. For best results, it is important that manufacturers, operators and service centres are equally dedicated to solve the fire problem. Vehicle fire investigations reveal that design, production, operation and maintenance can all be responsible, however, most important is to ensure that information and experiences from fire incidents and identified fire hazards are linked to relevant personnel, practices, manuals, and quality procedures. The certification cannot guarantee the elimination of vehicle fires, but can ensure that manufacturers, operators and service centres will operate at the front line of vehicle fire safety engineering.

New Test Method for Fire Detectors in the Engine Compartment of Heavy Vehicles

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Engine compartments of heavy vehicles are, in general, spaces where detecting fires with inexpensive and simple fire detection systems is arduous. High temperatures, high airflows, complicated geometries, large amounts of soil, dust and pollutants, and the wide range of surface temperatures, complicate the operation of all types of detectors. More advanced fire detection systems will, on the other hand, have durability issues caused by vibration, shocks, temperature variations and corrosion. SP Fire Research has developed a new test method to evaluate the detection performance as well as the durability of detection systems installed in engine compartments of heavy vehicles. A standardised test method would mean that only efficient detection systems are placed in service. SP Fire Research has worked over two years analysing engine compartments and fire scenarios from a fire detection point of view, including pre-tests of different fire detection systems. This article gives an overview of the challenges of heavy vehicle engine compartments with respect to fire detection and an outline of the new test method.
