The FR Mask functions as a counterpart to the Gas Mask, counteracting the effects of Incendiary Grenades and other fires. The FR Mask will reduce damage taken from exploding Incendiary Grenades and eliminates burning damage from fires caused by the grenades or elsewhere on the map. This makes the gadget useful in infantry focused areas where enemy players are consistently using Incendiaries, or on maps like The Block where fires can start. Alternatively, the FR Mask can also be equipped alongside Incendiary Grenades, allowing the player to be very aggressive with the grenades and not worry about taking damage from their own fires. The mask is effectively countered by Tear Gas, as the mask only blocks fire damage.
