Abstract: There is provided a fire collar comprising a casing defining a service conduit passage therethrough, the casing having an activation side and an installation side, wherein the casing defines an activation side located activation chamber. The fire collar has an opposing pair of shutters located within the activation chamber defining operative leading edges. In use, the shutters are configurable in a non-activated configuration wherein the leading edges are spaced apart so as to make allowance for the service conduit therebetween and when the fire collar is exposed to heat on the activation side in use, the shutters transition to an activated configuration wherein the respective leading edges of the shutters close in the passage.
