A metal scupper 1 comprising a walled funnel 2 having an inlet 3 and an outlet 4, and internally mounted annularly therebetween to the walls of the scupper, a layer of intumescent material 6. The layer of intumescent material may be provided as a water-resistant deformable sheet, or in flowable form. The scupper may further comprise a water-resistant heat deformable liner (8, Fig 2) having an entrance port and an exit port, both sealingly mounted to the inside of the scupper between the inlet and the outlet. The liner may have a body between the entrance port and the exit port, which is narrower than the scupper, thereby defining a void (9, Fig 2) between the walls of the liner body and a portion of the scupper annularity in which the intumescent material is encapsulated.
