DESCRIPTION:
BRIEF SUMMARY
The invention relates to a fire-proof cover as well as to its use.
The combat of small local fires is of a significant economical importance since these are often the origin of large fires which not seldom result in losses in the millions. Whereas in businesses and industries and government offices extinguishing devices generally stand ready for use, such extinguishing devices are entirely unsuitable, for example, in households since such extinguishing devices are expensive and difficult to manipulate. Moreover, such extinguishing devices lead to many secondary damages such as water damage, soiling and destruction caused by the chemical extinguishing agent or the like.
Accordingly, it is an object of the present invention to provide a fire-protection set comprising a fire-protection cover or blanket which has a high melting point, is flame-proof, and is substantially impermeable to gas, which can effectively smother a small fire because the cover cuts off the supply of oxygen to the fire, and which does not cause any secondary damage as a result of its use.
It is a further object to provide a fire-protection set which can be stored, for example, hung up, wherever small fires are possible.
A still further object is to provide a fire-protection set in which a fire-protection cover can be released from a container in seconds, ready for use.
Accordingly, one broad aspect of this invention resides in providing a fire-protection set characterized by a fire-protection cover made of a glass-fibre fabric substantially impermeable to gas, the said fabric being cut to a rectangle, provided with gripping tapes at adjacent corners and folded into a bundle or packet, and also comprising a bag-like container one narrow side of which is provided with a suspension means, while the other three sides have a rip-away weakening line.
One embodiment of the invention has been found particularly satisfactory in that the material of the cover softens at the temperature of a small fire. The advantage of this is that the said cover adapts more readily to the fire, thus cutting off the supply of oxygen more effectively.
The effect of the cover contained in the fire-protection set is improved if, according to another embodiment of the invention, it is provided with a flame-resistant agent which cuts off the supply of oxygen. Preferred flame-resistant agents are those which, upon burning, release nitrogen, since nitrogen is chemically inert, non-toxic, and therefore produces no unwanted or harmful side-effects. In this connection, special preference is given to nitrogen-containing phosphonates, because of the synergistic effect of organically combined nitrogen and organically combined phosphorus.
One embodiment of the invention comprises an arrangement of the gripping tapes which obliges the user to grip the loops of he wishes to open the container and remove the fire-protection cover. Using the said loops improves the user's grip and assists in ripping the container open.
Folding the fire-protection cover as indicated in other embodiments of the invention ensures, on the one hand, that the said cover can be folded into the smallest possible space and that the set, because of its small bulk, remains readily available and, on the other hand, that the cover contained in the set can be unfolded in case of need without any difficulty and without loss of time.
Fitting the suspension means to the narrow side of the container, so that the fire-protection set takes up less room laterally, always makes it possible to find a suitable place to hang the set up in the vicinity of potential sources of fire.
The relevant weakening lines may be in the form of perforations in the container or intentionally weak weld-seams in the case of a plastic container.
Possible uses for the fire-protection set are almost unlimited, for example, in the home, especially in the kitchen, during leisure time activities for extinguishing open fires and barbecues, for extinguishing carburetor fires in automobiles, and fires in workshops. In such cases, the fire-protectio
