Did you know that underground trains require the absolute strictest level of fire safety materials? 🚇🔥
Under the EN45545-2 standard, rail materials are rated from HL1 up to HL3. Because evacuating an underground tunnel is so challenging, metro systems demand HL3 compliance—the highest possible hazard rating! Using HL3 compliant rubber and sponge gaskets ensures that, in the event of a fire, the materials won't act as fuel and will drastically limit the release of toxic smoke. This gives passengers the crucial visibility and time needed to evacuate safely.
