Method of assisting a compromised barrier
View Patent ↗The present invention provides method, apparatus, and system to assist in partially or fully reestablishing the fire rating of a barrier that has been compromised by the installation of an electrical box(es) in the barrier. The electrical box includes a faceplate having a fire retardant material, such as an intumescent material, coupled to the faceplate and/or coupled between the box and the faceplate. The fire retardant material enhances the fire resistance of the compromised area of the barrier. In one embodiment, the fire retardant material can be in the form of a gasket that can be used cooperatively with the faceplate and the electrical box. In another embodiment, the fire retardant material can be established on one or more surfaces of the faceplate by molding, spraying, dipping, coating or any other methods of application of the material to a surface.
1. A method of assisting a compromised barrier, comprising:
a) providing a gasket comprising fire retardant material of a fire resistant insulative material containing mineral wool or intumescent graphite;
b) placing the fire retardant gasket between a faceplate and an electrical box adapted to be introduced into the barrier;
c) coupling the faceplate to the box; and
d) at least partially reestablishing a fire rating of the barrier.
2. The method of claim 1 , further comprising coupling the gasket in situ between the faceplate and the box.
3. The method of claim 1 , wherein providing the gasket comprises forming the gasket as a separate element prior to placing the gasket between the faceplate and the box.
4. The method of claim 1 , further comprising forming the gasket on one or more surfaces of the faceplate prior to coupling the faceplate to the box.
5. The method of claim 4 , wherein the gasket is formed by establishing a coating of the fire retardant material onto the faceplate.
6. A method of assisting a compromised barrier, comprising:
a) installing into a fire-rated barrier an electrical box, the electrical box compromising the fire resistance of the fire-rated barrier;
b) introducing into the electrical box a fire retardant gasket of a fire resistant insulative material containing mineral wool or intumescent graphite; and
c) covering the electrical box with a faceplate.
7. The method of claim 6 , wherein the fire retardant gasket is adhered to the faceplate prior to covering the electrical box with the faceplate.
8. The method of claim 6 , wherein the fire retardant gasket is introduced to the electrical box without removing the electrical box from the fire resistant barrier.
