What is claimed is: 1. A portable cart for transporting and storing oxygen and fuel gas cylinders comprising: a platform for supporting an oxygen gas cylinder and a fuel gas cylinder in an upright side by side arrangement; a frame structure attached to said platform for containing said oxygen gas cylinder and said fuel gas cylinder, and; a calcium silicate panel fixed between said oxygen gas cylinder and said fuel gas cylinder, wherein said calcium silicate panel obstructs all lines of sight between said oxygen gas cylinder and said fuel gas cylinder, and said calcium silicate panel is comprised of a laminate of two outer calcium silicate sheets and at least one inner calcium silicate sheet of lower density than said outer calcium silicate sheets. 2. A portable cart for transporting and storing oxygen and fuel gas cylinders as recited in claim 1 wherein said two outer calcium silicate sheets each have a density of between 28 and 100 pounds per cubic foot and are between ½ and 1 inch thick, and said inner calcium silicate sheet is between ½ and 1½ inches thick. 3. A portable cart for transporting and storing oxygen and fuel gas cylinders as recited in claim 1 further comprising a barrier frame securing said calcium silicate sheets and encircling the edges of said calcium silicate sheets. 4. A portable cart for transporting and storing oxygen and fuel gas cylinders comprising: a platform for supporting an oxygen gas cylinder and a fuel gas cylinder in an upright side by side arrangement; a frame structure attached to said platform for containing said oxygen gas cylinder and said fuel gas cylinder, and; a calcium silicate panel fixed between said oxygen gas cylinder and said fuel gas cylinder, wherein said calcium silicate panel is fixed so that the entire width and depth of said calcium silicate panel at its lower end is in contact with said platform, and said calcium silicate panel obstructs all lines of sight between said oxygen gas cylinder and said fuel gas cylinder by said entire width of said calcium silicate panel, and wherein said calcium silicate panel is comprised of a number of calcium silicate sheets fixed in parallel separation from one another forming an air gap open on at least three sides between adjacent calcium silicate sheets. 5. A portable cart for transporting and storing oxygen and fuel gas cylinders as recited in claim 4 wherein said calcium silicate sheets each have a density of between 28 and 100 pounds per cubic foot and are between ½ and 1 inch thick, and said air gap is between ¼ and 1 inch. 6. A portable cart for transporting and storing oxygen and fuel gas cylinders comprising: a platform for supporting an oxygen gas cylinder and a fuel gas cylinder in an upright side by side arrangement; a frame structure attached to said platform for containing said oxygen gas cylinder and said fuel gas cylinder, and; a calcium silicate panel fixed between said oxygen gas cylinder and said fuel gas cylinder, wherein said calcium silicate panel obstructs all lines of sight between said oxygen gas cylinder and said fuel gas cylinder, and said calcium silicate panel is comprised of a number of calcium silicate sheets fixed in parallel separation from one another forming an air gap between adjacent calcium silicate sheets, and has a barrier frame securing said calcium silicate sheets, encircling the edges of said calcium silicate sheets and enclosing said air gap.
