Different hazard levels
Rail vehicles are classified at one of three different hazard levels, namely HL1, HL2 and HL3. HL1 is the lowest requirement and HL3 is highest. The level is established on the basis of two factors. First, the route travelled by the relevant rail vehicle, with an important factor being how fast a passenger can reach a safe place in the event of fire. Second, the level also depends on the type of rail vehicle, for example sleeping cars, double decker, etc.
The table below lists the SABA products that are EN 45545-2 certified, the type of application and the hazard level they may be used for.
