Intumescent coated vent for large passenger vehicles

Abstract

A vent with louvres or punched holes for allowing airflow between an exterior of a vehicle and an engine bay of the vehicle, wherein the vent has an exterior side and an interior side and is formed from a panel, in which the louvres or the punched holes are located, wherein the interior side of the vent is provided with an intumescent coating. The intumescent coating will inhibit the spread of flame from the engine bay to the exterior of the vehicle thus containing the fire for a much longer period.
