Abstract

A containment device for use as a receptacle for a suspect explosive device comprises a tube arranged in use to form a receptacle bin and a support, e.g. a net, within the tube for supporting the suspect device. The material of the tube incorporating a continuous elongate reinforcing material e.g. glass fibre impregnated with resin.

Description

BOMB CONTAINMENT DEVICE This invention relates to containment devices for use as receptacles for suspect explosive devices.
Explosive devices concealed in letters or postal packages obviously present a real hazard to postal workers handling the devices during their transmission through the post quite apart from the addressees of the items.
If in the course of handling postal items, a postal bomb is discovered or suspected, the postal item is immediately isolated and one convenient method of achieving such isolation is to place the item in a receptacle which has been constructed as a containment device.
The item will be kept in the receptacle pending further investigation by specialist personnel and/or controlled explosion. In some instances, the explosive device may explode involuntarily on or after being placed in the receptacles.
Known receptacles or "bomb boxes" as they are termed rely on a large mass in the form of an infill of blast absorbing material, to absorb the blast and shrapnel effect of the explosion, but these have been found to be cumbersome and therefore unmanageable, and also expensive.
An object of the invention is to provide an improved containment device.
According to the present invention, a containment device for use as a receptacle for a suspect explosive device comprises a tube arranged in use to form a receptacle bin and a support within the tube for supporting the suspect device, wherein the material of the tube incorporates a continuous elongate reinforcing material.
The reinforcing material may be glass.
In a preferred form, the tube comprises a winding of filament glass fibre or of one or more glass rovings, the fibre or the rovings as the case may be, being impregnated with a bonding resin material, preferably a polyester resin material.
In a specific example, the support comprises a net of polypropylene material.
One embodiment of the invention will now be described.
A containment device for use as a receptacle for suspect postal bombs comprises an open ended tube which in use is placed in the upright position.
The tube is constructed of one or more E glass continuous rovings incorporated in a halogenated polyester resin mix and has a net of polypropylene material secured to the wall of the tube approximately midway along the length of the tube, to form a support for any suspect postal bomb placed in the receptacle.
Typical dimensions for the tube are:- height 900 mm, outside diameter 490 mm and thickness 18-19 mm.
In use, the receptacle will be placed in a convenient position in a postal handling area and should any postal item being handled appear to be suspect at all, the item will immediately be placed in the receptacle in order to isolate the item.
It has been found that a receptacle of the construction described has a very enhanced burst strength and should the postal item explode either involuntarily on or after being placed in the containment device, or as a result of a controlled explosion following investigation by specialist personnel, the receptacle will contain the explosion within the limits of explosive levels experienced to date. In more detail, in the event of such explosion, fragments of the explosion will either become embedded in the wall of the tube or will fall through the net.
The burst strength of the tube is of course related to the diameter and wall thickness of the tube, some reduction of wall thickness being permitted as the diameter increases. Additional wall thickness may be achieved by building up the tube in layers or laminations of rovings suitably impregnated with a bonding resin material.
Alternatively to the glass roving or rovings as described above, the tube may comprise a tube wound from a filament of glass fibre impregnated with a polyester resin material.
If desired, the tube may comprise an ultra-violet inhibiter in the resin matrix formed during the production stage which is particularly advantageous if the receptacle is to be kept in the open air during use since ultra-violet radiation can have a deleterious effect on either the plasticiser in the polymer of the resin or on the polymer itself.
Furthermore, the surface of the tube may additionally have a resin rich make-up so as to resist water ingression in the event of edges of the tube being cut or slightly damaged.

Claims (9)

CLAIMS:
1. A containment device for use as a receptacle for a suspect explosive device comprising a tube arranged in use to form a receptacle bin and a support within the tube for supporting the suspect device, wherein the material of the tube incorporates a continuous elongate reinforcing material.
2. A containment device as claimed in claim 1, wherein the reinforcing material is glass.
3. A containment device as claimed in claim 2, wherein the tube comprises a winding of filament glass fibre impregnated with a resin bonding material.
4. A containment device as claimed in claim 2, wherein the tube comprises a winding of one or more continuous glass rovings impregnated with a resin bonding material.
5. A containment device as claimed in claim 3 or 4, wherein the resin bonding material comprises a polyester resin material.
6. A containment device as claimed in any preceding claim, wherein the support comprises a net of polypropylene material.
7. A containment device as claimed in claim 3 or 4 or any dependent claim thereof, wherein the tube has an ultra-violet inhibitor incorporated in the resin.
8. A containment device as claimed in claim 3 or 4 or any dependent claim thereof, wherein the tube has a resin rich make-up to resist the ingress of water in the event of edges of the tube being damaged.
9. A containment device substantially as hereinbefore described.
