Description
SPECIFICATION
Refuges for use in hazardous environments
The present invention relates to a refuge for use by
a person in a hazardous environment.
It is found to be necessary to carry out on oil tank
ers at sea maintenance operations which require
crew members equipped with breathing apparatus to enter oil containing holds after oil has been dis
charged from them. The crew members enter the
hold through hatches, descend ladders to the bottom
of the hold and then work their way across the bot
tom of the hold to the point where maintenance is
required. They can be required to walk as far as 100
to 150 feet (30 to 50 metres) in the hold, the time
taken to walk this distance usually being greatly
increased by the need for them to climb over struc
tural support members which form part of the bot
tom of the hold.As the usual supply of breathable
gas lasts for thirty minutes only, as much as half the
available supply of gas can in some instances be
used up in moving to and fro from the point where
maintenance is required.
Empty oil tanker holds contain dangerous vapours
and in the case of empty sea water ballast tanks
there is invariably a serious deficiency of oxygen,
due to the continuous process of corrosion within the
tank. There is therefore always the risk of a crew
member within the hold being overcome by such
vapours or by lack of oxygen when, for example, his
breathing apparatus develops a fault or becomes
exhausted. In such emergencies, rescue has been
found to be very difficult because of the distance of
the crew member from an access hatch and the diffi
culty of moving him along the floor of the hold to the
base of the ladder leading to the hatch, lifting him
where necessary over the structural supports obs
tructing the way.
It is an object of the present invention to provide a
refuge for crew members in such emergencies.
According to the present invention, there is pro
vided a refuge transportable in a collapsed disposi
tion and deployable to a deployed disposition in
which it forms an enclosure for accommodating at
least one person, the refuge comprising a floor
which provides a load bearing floor surface suffi
cient to support the weight of the person, a cover
erectable above the floor to form the enclosure and
means for supplying to the enclosure a breathable
gas under pressure from a source remote from the
refuge, the cover including a closable entrance open
ing by which a person may gain access to the
enclosure, and the floor, the entrance opening when
closed and the cover being such as to prevent during
use of the refuge in the deployed disposition the
ingress of ambient gas to the closure at least when
breathable gas in being supplied thereto under said
pressure.
Preferably, the floor is collapsible and, in a prefer
red embodiment of the invention, comprises a plur
ality of planks arranged in side-by-side relationship with adjacent edges of adjacent planks connected together in such a way that they can be moved relative to each other from a deployed disposition in which the planks are coplanar and form the floor surface to a rolled disposition in which the planks are rolled up about an axis parallel to the length of the planks. Adjacent edges of adjacent planks may conveniently be connected together by fabric hinges.
The planks in the rolled disposition form a longitudinally extending cavity surrounded by the planks and within which is housed the cover when collapsed. Each end of the cavity may be closed by an end piece, the two end pieces being connected to one of the planks and each end piece being of such a shape as to serve as a foyer for supporting the innermost planks in the rolled disposition. The refuge is preferably arranged to be of such dimensions that in the collapsed disposition, that is to say, with the planks in the rolled disposition and the cover housed within the cavity, it can be passed through a circular opening having a diameter of 12 inches (30.48 cm).
The cover in the deployed disposition of the refuge may be supported by an inflatable tube structure and means may be provided for inflating the structure from the source of breathable gas under pressure or from a further source of gas under pressure. The cover and the inflatable tube structure is preferably detachably secured to the floor and in the collapsed disposition contained in the cavity formed by the planks in their rolled disposition. The detachable cover and inflatable tube structure is preferably secured by lacing to an upstanding skirt extending around and secured to the periphery of the floor.
The cover and the floor are preferably so formed and connected together as to permit in the deployed disposition of the refuge a controlled escape of breathable gas. The closable entrance opening may be closed by a door flap of flexible material which may be held closed by magnetic means supplemented, if desired, by a mechanical fastener, such as some form of press fastener.
The following is a more detailed description of one embodiment of the invention by way of example, reference being made to the accompanying drawings in which:
Figure 1 is a perspective view of a refuge in a deployed disposition;
Figure 2 is a perspective view of the refuge of Figure 1 in a collapsed disposition;
Figure 3 is a perspective view of the floor of the refuge of Figures 1 and 2 in the deployed disposition with some parts omitted for clarity;
Figure 4 is a section of a part of the deployed floor shown in Figure 3, taken on the line IV-IV in Figure 3;
Figure 5 is an end elevation of the refuge shown in
Figure 1 in the deployed disposition and fitted with a door;
Figure 6 is a section of part of the refuge shown in
Figure 5, taken on the line VI-VI in Figure 5; and
Figure 7 is a scrap perspective view of part of the refuge shown in Figure 1, viewed in the direction of thearrowVll in Figure 1.
Referring first to Figure 1, the refuge comprises a rectangular floor 10 and a cover 11 above the floor.
The floor 10 forms a surface which will support at least one person in a lying down posture and the enclosure formed by the floor 10 and the cover 11 is of a size sufficientto accommodate at least or.e person.
Referring next to Figures 3 and 4, the floor 10 comprises nine planks 12 made from wood and arranged in side-by-side relationship. The planks are hinged together along their longer side edges by fabric hinges 13 covered by fabric strips 33. The second plank in from one edge of the floor 10 carries two trapezoidal end pieces 14 located towards respective ends of the planks.
The hinges 13 allow the planks 12 to be rolled up about an axis parallel to the lengths of the planks 12, as seen in Figure 2. The combination of strips 33 and hinges 13 allow the floor assembly to be rolled in one direction only, that is to say, upwardly and over as shown. The end pieces 14 locate the first four planks of the floor 10 in the roll so that they define a cavity extending between the end pieces, which close the ends of the cavity.
In the collapsed disposition of the refuge shown in
Figure 2, the cover 11 is contained within the cavity.
The roll of planks is secured by straps 15 tensioned by tensioning buckles (not shown) and releasable by quick release buckles 17 and, at each end of the roll, a bridle 18 is provided by which the collapsed refuge may be raised and lowered. Carrying handles 19 are also provided. At each of the release buckles 17, one end of the strap 15 is provided with a link 17a, through which is passed a fabric loop formed by the other end of the strap 15. A quick release pin 17b which is secured to a release lanyard 16 passes through the loop and prevents the two ends of the straps from separating.The operating end of the lanyard 16 is loosely attached to the bridle 18 as shown and the arrangement is such that pulling of the lanyard 16 withdraws both pins 1 7b from the looped ends of the straps 15 releasing the connection between the two ends of the straps and freeing the planks for unrolling.
The dimensions of the collapsed refuge are such that it can be passed endwise through an opening of 12 inches (30.48 cm) in diameter.
Referring again to Figure 1, the cover 11 covering the floor 10 comprises two side walls 20, a roof 21 and two end walls 22 which are stitched together and the cover 11 is connected to an upstanding skirt 23 secured to the floor 10. The connection is by lacing 24 which passes through eyelets in the lower edges of the walls and in the skirt 23. One of the end walls 22 includes an opening 25 which can be closed by a door 26 omitted from Figure 1, but clearly shown in Figures 5 and 6.
Referring now to Figures 5 and 6, the door 26 comprises a fabric panel 27 connected along one edge to an upper edge of the opening 25. The door 26 is provided along each side edge and along the bottom edge with flexible magnetic strips 28 and 30, sewn on to the fabric forming the door panel 27. The strips 28 and 30 cooperate with similar strips 29 and 31 sewn on to the fabric forming the end wall 22 of the cover 11, the poles of the magnetic strips being so arranged that they attract each other and hold the two side edges of the door panel 27 against the edges of the door opening 25. The magnetic strips 28 to 31 are of substantial width and provided a good area of magnetic contact. They are, furthermore, sewn on to the face of the fabric which supports them so as to leave the cooperating faces free for direct contact with each other when the door panel 27 is closed.
The cover 11 is, as best seen in Figure 1, maintained in the deployed disposition by an inflatable tube structure. The structure comprises two side tubes 41 of inverted generally U-shaped configuration and spced apart by three spacer tubes 42. The side tubes 41 have their closed ends held on the floor 10 by lacing 43 connecting the ends of the side tubes 41 to fabric corner pieces 44 fastened to the floor 10 and by "press to close" type fasteners, the components of which are secured to the planks at each corner and to the corresponding underside of the inflatable tube ends.
Each upright corner tube and each transverse tube is fitted with an inwardly directed pressure relief valve 45, the purpose of which will hereinafter be described. Two deflation plugs 46, one of which is shown in Figure 5 are provided for deflation of the tubes 41 and 42 when the refuge is to be collapsed.
When collapsed, the tubes 41 and 42, the walls 20 and 22 and the roof 21 are located in the cavity formed by the roll of planks 12, as shown in Figure 2.
Referring now to Figure 7, the end of the refuge remote from the door panel 27 is provided with an inlet 48 for connection through a pipe 52 to a supply of air under pressure remote from the refuge. The inlet 48 is connected by a flexible hose 49 direct to a non-return inflation valve 50 provided as shown in the support tube 41. In operation, air under pressure is supplied from a remote source through the supply pipe 52 and fed to the interior of the inflatable tubes 41 and 42 causing them to inflate. When the inflation pressure reaches a predetermined value sufficient to hold the structure erect the relief valves 45 automatically open to provide a continuous supply of air to the enclosure.
The refuge described above with reference to the drawings can be used with advantage on sea-going oil tankers. The roof of the hold of an oil tanker is normally fitted at about 10 feet (3.048 m) spacing with Butterworth openings, Butterworth being a trade name. The openings are about 12 inches (30.48 cm) in diameter and can be used for lowering a collapsed refuge, as shown in Figure 2, into the interior of the hold.
In an emergency, an opening is chosen which will bring a lowered refuge to the immediate proximity of a disabled crew member within the hold. Before lowering the collapsed refuge, the inlet 48 is connected by the pipe 52 to either a ship's compressed air supply, where such is available, or to one or more foot operated pumps. The collapsed refuge is then lowered vertically through the selected opening using the bridle 18 and once the refuge is clear of the deck level the lanyard 16 is pulled to release the quick release buckles 17. The roll of planks 12 is then free to unroll and air under pressure from the supply is then immediately applied to inflate the inflatable tubes41 and 42 which upon inflation unroll the planks 12 and cause the refuge to take up its deployed disposition as shown in Figure 1.When the tubes 41 and 42 reach their full inflation pressure the relief valves 45 automatically open to discharge air into the enclosure. The process of inflation and the supply of air to the enclosure is carried out as the refuge is being lowered so that when the refuge reaches the bottom of the hold it is ready for immediate occupation. In the collapsed condition, the door panel 27 is maintained in the closed position and remains in this position upon inflation of the tubes 41 and 42. To ensure that the door panel 27 remains closed when the refuge is being inflated and lowered in the hold, supplementary fastening means such as press fasteners may be used. By so maintaining the door closed during inflation, the refuge will arrive at the bottom of the hold fully inflated with the interior filled with breathable air.Air supplied to the interior of the refuge through the valves 45 is at a pressure greater than the pressure of ambient gas around the refuge and prevents such gas entering the refuge, air leaving the interior of the-enclosure around the door panel 27 and through the eyelets in the base of the cover 11. Where the refuge is inflated with the door panel 27 in an open position vapours present in the hold are drawn into the enclosure and will take some time to be displaced by air discharged from the relief valves 45. Where the noxious vapours are heavier than air and collect at the base of the hold, it is, therefore, in any event, preferable to inflate the refuge as soon as it is below deck level.
The crew member in need of the refuge pushes open the door panel 27 and climbs inside, closing the door panel behind him. He then remains within the enclosure until help arrives or until he is sufficiently revived to make his way to the access hatch.
Further air cylinders may be lowered through the opening in the roof of the hold to replace exhausted cylinders of the breathing apparatus.
The refuge may, if desired, be permanently deployed in a hold while maintenance is taking place to provide an enclosure to which a crew member may retreat if fumes begin to overcome him. The refuge may, if desired, be made sufficiently large to accommodate more than one person. Lashings may be provided for lashing a crew member to the floor 10 to prevent him being thrown around in rough seas. Clamps may be also provided on the underside of the floor to clamp the refuge to the ship's structure.
Referring again to Figure 1, an adaptor 53 is provided in the side wall 20 of the cover 11 and may be connected by a flexible pipe (not shown) to apparatus on the deck for monitoring air conditions withintherefuge.
In the embodiment of the invention hereinbefore described with reference to the drawings, the cover 11 is supported by inflatable tubes 41 and 42. The cover may, if desired, be supported in the deployed disposition of the refuge by any other form of collapsible supporting structure, such, for example, as a framework of metal, wood or plastics struts and the supply of air under pressure applied direct from the inlet 48 into the enclosure.
The cover 11 may, if desired, be held in the deployed disposition by arranging for breathable gas to be supplied to the enclosure at a pressure sufficiently greater than the pressure of the ambient gas that the cover is held inflated thereby.
The cover 11 in the embodiment of the invention hereinbefore described is gas impervious and the arrangement is such as to permit a controlled escape of breathable gas from the enclosure through outlets provided in the cover 11. If desired, however, the cover may be made from a material pervious to the breathable gas to provide for the controlled escape of the breathable gas from the enclosure.
In the embodiment hereinbefore described, the breathable gas is applied to upper and lower regions of the enclosure in the deployed disposition of the refuge. In situations where the ambient gas is heavier than the breathable gas supplied to the enclosure the relief valves may, if desired, be located in the upper regions only of the enclosure. In situations where the ambient gas is lighter than the breathable gas, the breathable gas may be supplied by relief valves to the lower regions only of the enclosure.
The enclosure may be insulated against loss of heat, for example, by providing the cover in the form of a double skin or by lining the interior of the cover with a heat insulating material.
While the floor 10 in the embodiment of the invention hereinbefore described is formed by rigid planks 12, it may if desired be formed by an inflatable structure such as an inflatable cushion suitably reinforced to support the weight of one person. The cushion may include a connection to permit inflation from the source of breathable gas used for inflating the inflation tubes 41 and 42 or for inflation from an alternative source of gas under pressure.
