Abstract
A fire barrier material (1) for use as afire blanket comprises a low permeability flexible layer (2) interposed between two layers of glass fibre fabric (3). Preferably the glass fibre fabric is woven and the three layers are sewn together (4). The low permeability flexible layer (2) may be a thermoplastic film eg polyvinyl chloride or polypropylene, and may also be flame retardant. The material is especially suitable for extinguishing chip pan fires. <IMAGE>
Description
FIRE BARRIER MATERIAL
This invention relates to a fire barrier material for use as a fire blanket.
It is well known that one of the most difficult domestic fires to deal with is a burning chip pan.
Because of the oil, the temperature of such a burning pan can be so high that only a limited number of materials have the requisite fire barrier properties and flexibility for use against the fire. A further problem is that the oil vapours easily reach a temperature above their flashpoint; if the material is permeable the vapours will pass through it and ignite above it.
Known fire blankets are made from various fire barrier materials, but all have disadvantages. Glass fibre fabric is flexible, relatively inexpensive and an effective fire barrier, but is permeable. It can be coated with silicon to render it impermeable, but then becomes less flexible and more expensive. Another known material comprises a PVC (polyvinyl chloride) film sandwiched between two fire retardant textile layers. This is flexible, substantially impermeable and effective as a fire barrier, but is relatively bulky and expensive.
According to the present invention, a fire barrier material for use as a fire blanket comprises a low permeability flexible layer interposed between two layers of glass fibre fabric.
The glass fibre fabric layers provide an effective fire barrier, whichever way up the material is used, while the low permeability layer substantially prevents vapours passing through the material. Further, the material is flexible and inexpensive to manufacture.
Preferably the glass fibre fabric is woven, and each layer is thinner and of a lighter weight than is usual for fire barrier material. The selvedges of the fabric may be sealed.
The low permeability layer is preferably a thermoplastics film. Conveniently a non-permeable film such as a PVC sheet is used. Alternatively polypropylene may be used. The low permeability layer may also be fire retardant.
The fire barrier material constructed from the three layers in this way is thinner than usual having a thickness of 0.50 mm + 10.
The three layers may be connected together in any convenient way. Sewing is preferred, as it is inexpensive and ensures that the material is flexible.
Thus, continuous lengths of fabric and film are sewn together by a line of stitching adjacent each selvedge.
One or more lines of stitching may be placed between the two selvedge lines. Nylon thread is preferably used for the stitching.
The fire barrier material made in this way is particularly effective as a fire barrier, being flexible, substantially impermeable, and inexpensive.
It is especially suitable for use as a domestic fire blanket. Individual fire blankets can readily be made by cutting å length from the continuous material, and finishing the cut edges by overlocking, again with nylon thread. One edge may also be hemmed and have handles attached.
Embodiments of a fire barrier material and a fire blanket in accordance with the invention are illustrated in the accompanying drawings, in which:
Figure 1 is a diagrammatic cross-section through
a fire barrier material; and
Figure 2 shows a fire blanket made from the
material of Figure 1.
The fire barrier material 1 of Figure 1 is layered, and comprises a low permeability flexible layer 2 interposed between two layers of glass fibre fabric 3, the layers 2,3 being connected by stitching 4.
The layer 2 is of fire retardant PVC (polyvinyl 2 chloride) film, which has a weight of 130 g/m2 and a thickness of 0.1 mm. This film is substantially impermeable to gas and vapour, and will tend to melt at high temperatures.
The layers 3 are identical in structure, each being of woven glass fibre fabric having a weight of 2 approximately 200 g/m2, and a thickness of about 0.20 mm. The selvedges of the fabric are sealed. The fabric is substantially thinner and lighter than that normally used as fire barrier material.
The stitching 4 connecting the layers 2,3 uses nylon thread. Continuous lengths of the layers 2,3 are stitched together by a line of stitching adjacent each selvedge, together with one or more lines between these two selvedge lines. Figure 1 shows just one line of stitching 4.
The fire barrier material 1 made in this way is flexible, inexpensive to make, and relatively lightweight. It is also effective as a fire barrier, due to the two layers of glass fibre 3, and substantially impermeable, due to the PVC film 2. The stitching 4 increases the permeability of the film 2 very slightly, but the effect is in fact negligible, and the film 2 is still of sufficiently low permeability to prevent the passage of vapours through the material. At high temperatures the film 2 melts, but the material 1 retains its low permeabiLity characteristic.
The material is particularly suitable for use as a domestic fire blanket, and Figure 2 shows such a blanket.
The blanket 5 shown in Figure 2 is rectangular in shape, and is cut from a length of the material 1 having three lines of stitching 4. As can be seen in
Figure 2, each line of stitching 4 adjacent a selvedge 6 is about 1.5 cm from the edge of the material, while the third line of stitching 4 is approximately central. The other, cut edges 7,8 of the blanket 5 are neatened by overlocking with nylon thread. The edge 8 is also turned back, and a hem 9 of approximately 1.5 cm is formed. A pair of handles 10 are sewn into the hem 9. Each handle 10 is of cotton, with a metal tip 11, and each is positioned about 15 cm from an adjacent selvedge 6. A label 12 is also sewn into the hem 9.
The blanket 5 shown in Figure 2 can easily be folded or rolled for storage, and equally easily opened out for use on a fire, by using the handles 10.
In a modification the fire barrier material, from which the fire blanket is made, is provided with two or more lines of stitching between the line of stitching adjacent each selvedge.
The material 1 may be modified by the use of a different material for the layer 2, such as for example, polypropylene or a film of different plastics material.
