Fire resistant protective barrier and a method for its use

Abstract

A protective barrier that will typically be installed beneath ceilings during construction work being performed on ceilings or roofs of buildings. The protective barrier can be comprised entirely of one material or multiple materials connected by seams. Some or all of these materials can be fire resistant or fireproof, thereby creating a firebreak in the barrier, which can prevent the fire from spreading to the entire protective barrier and the rest of the building where the protective barrier has been deployed.

1 . A protective barrier for preventing dust and debris from passing through it, comprised of a fire resistant or fireproof material. 
     
     
         2 . The protective barrier as recited in  claim 1 , wherein when a section of the barrier is suspended in air and exposed to fire, the fire resistant or fireproof material prevents the fire from spreading from one part of the protective barrier to another part of the protective barrier. 
     
     
         3 . The protective barrier as recited in  claim 1 , wherein the fire resistant or fire proof material is a boron-containing polymer. 
     
     
         4 . The protective barrier as recited in  claim 1 , wherein the fire resistant or fireproof material is at least partially comprised of a sprayed on fire resistant or fireproof coating. 
     
     
         5 . The protective barrier as recited in  claim 4 , wherein the fire resistant or fireproof coating is an intumescent. 
     
     
         6 . The protective barrier as recited in  claim 4 , wherein when a section of the barrier is suspended in air and exposed to fire, the fire resistant or fireproof coating prevents the fire from spreading from one part of the protective barrier to another part of the protective barrier. 
     
     
         7 . A protective barrier, comprising:
 a first section made of translucent or transparent material and a second section made of a translucent or transparent material; and   a seam comprising a fire resistant or fireproof material, the seam joining the first section and second section and completely separating and surrounding the first section and the second section.   
     
     
         8 . The protective barrier as recited in  claim 7 , wherein when a section of the protective barrier is suspended in air and exposed to fire, the plurality of seams prevents the fire from spreading from one section to another section. 
     
     
         9 . The protective barrier as recited in  claim 7 , wherein the fire resistant or fireproof material is at least partially comprised of a sprayed on coating. 
     
     
         10 . The protective barrier as recited in  claim 7 , wherein the material that is fire resistant or fireproof is Nomex. 
     
     
         11 . The protective barrier as recited in  claim 7 , wherein the material that is fire resistant or fireproof is a boron-containing polymer. 
     
     
         12 . The protective barrier as recited in  claim 7 , wherein the sections of translucent or transparent material are comprised of a polymer. 
     
     
         13 . The protective barrier as recited in  claim 7 , wherein the seams are located along edges of the sections. 
     
     
         14 . A method for using a protective barrier, the method comprising:
 providing a planar sheet comprising a fire resistant or fireproof material; and   elevating the planar sheet above a floor,   wherein the planar sheet prevents dust or debris from reaching the floor.   
     
     
         15 . The method as recited in  claim 14 , wherein the planar sheet comprises at least two seams of the fire resistant or fireproof material connected by sections of a translucent or transparent material. 
     
     
         16 . The method as recited in  claim 14 , further comprising:
 a portion of translucent or transparent material catching on fire and the fire spreading along translucent or transparent material; and   coming into contact with the fire resistant or fireproof material, which prevents the fire from spreading further.   
     
     
         17 . The method as recited in  claim 14 , wherein the fire resistant or fireproof material comprises a boron-containing polymer. 
     
     
         18 . The method as recited in  claim 16 , wherein the translucent or transparent material is a polymer. 
     
     
         19 . The method as recited in  claim 14 , wherein the fire resistant or fireproof material comprises Nomex. 
     
     
         20 . The method as recited in  claim 14 , wherein the fire resistant or fireproof material comprises an antimony-containing polymer. 
     
     
         21 . The method as recited in  claim 14 , wherein the fire resistant or fireproof material is at least partially comprised of a sprayed on fire resistant or fireproof coating.
