Surespan has manufactured and supplied a series of fire escape hatches at Portugal’s new €950 million underground Metro in Porto.
The huge double leaf hatches automatically open if the fire alarm system is activated to allow passengers safe exit to ground level. In addition they can be manually opened with the touch of a button.
