You may be aware that 37 countries have signed on to adopt the UNECE R107 regulation. This rule is intended to make bus transport safer by reducing the risk of catastrophic bus engine fires. When a bus fire starts in an engine, the driver and passengers often don’t realize the danger until the fire has already grown very large. That’s why UNECE R107 requires installation of automatic fire suppression systems in bus engines.
Here’s what the R107 standard specifically requires:
Firetrace bus engine fire suppression systems have passed all 11 SP Method 4912 tests. This includes both the fire tests required by R107 and additional tests to ensure that the systems can survive the harsh environment of a bus engine. That means that Firetrace systems are both R107 compliant and PMark SPCR 183 certified.
However, just because the systems have passed testing doesn’t mean that every system sold is automatically compliant. Installing companies also need to comply with these specific requirements:
First, a fire risk assessment must be completed when laying out a system design for a specific bus engine. Installers can download a fire risk assessment here. This document must be signed off by the Firetrace engineering team before the suppression system can be purchased and installed.
Second, after the system is installed, the installer must complete a Declaration of Installment. This ensures that the system was installed according to the guidelines outlined in the risk assessment.
In summary, to ensure that a fire suppression system meets all of the requirements of UNECE R107:
