Weiterhin betrifft die Erfindung eine Anordnung umfassend eine Windkraftanlage und die obige Rettungsvorrichtung.The invention relates to a rescue device for safely rescuing a person from a wind power plant in the long term. Furthermore, the invention relates to an arrangement comprising a wind turbine and the above rescue device.

Hintergrund der ErfindungBackground of the Invention

Moderne Windenergieanlagen beinhalten Fahrstühle, mittels derer Monteure und Servicetechniker in die Gondel der Windenergieanlage gelangen können, um dann innerhalb der Gondel ohne Risiko eines Absturzes ohne Gurt arbeiten zu können. Im Falle eines Unfalls, beispielsweise aufgrund eines Herzinfarktes, eines Schwächeanfalls, einer Stoß- oder Schnittverletzung oder dergleichen, kann der verunfallte Monteur oder Servicetechniker nicht selten nicht mehr selbständig in den Fahrstuhl gelangen, da aufgrund beengter Platzverhältnisse in der Gondel der Zugang zum Fahrstuhl oftmals eng und verwinkelt ist. Analoges gilt bei einem Brand in der Gondel oder an einem Turm der Gondel. In beiden Fällen ist eine schnelle Evakuierung des verunfallten Monteurs oder Servicetechnikers aus der Gondel notwendig.Modern wind turbines contain elevators, by means of which fitters and service technicians can get into the nacelle of the wind turbine in order to then be able to work inside the nacelle without the risk of falling without a seat belt. In the event of an accident, for example due to a heart attack, a fainting fit, an impact or cut injury or the like, the fitter or service technician involved in the accident can often no longer get into the elevator independently, since access to the elevator is often narrow due to the restricted space in the gondola and is crooked. The same applies to a fire in the nacelle or on a tower of the nacelle. In both cases, the mechanic or service technician involved in the accident must be quickly evacuated from the gondola.

Zur Evakuierung werden in der Gondel Rettungseinrichtungen zum Retten- und Evakuieren von Personen in ausreichender Anzahl und zum schnellen Zugriff vorgehalten. Die Rettungseinrichtungen müssen in regelmäßigen Zeitabständen gewartet bzw. auf ihre Funktionalität und Einsatzfähigkeit hin überprüft werden. Beispielsweise ist es notwendig, Rettungsgeräte, auch ungenutzte, die für Notfälle vorgehalten werden, mindestens einmal jährlich zu prüfen, damit diese im Notfall in technisch einwandfreiem Zustand sind und nicht durch beispielweise Korrosion untauglich sind. Gleichzeitig unterliegen bestimmte Komponenten der Rettungseinrichtungen einer Alterung und müssen in regelmäßigen Zeitabständen, beispielsweise alle 10 Jahre ausgetauscht werden. Dies ist mit zusätzlichem Aufwand und Kosten verbunden.For evacuation, rescue facilities for rescuing and evacuating people are kept in sufficient numbers and for quick access in the gondola. The rescue facilities must be serviced at regular intervals and their functionality and operational capability must be checked. For example, it is necessary to check rescue equipment at least once a year, including unused ones, which are kept available for emergencies, so that they are in a technically perfect condition in an emergency and are not unusable due to corrosion, for example. At the same time, certain components of the rescue facilities are subject to aging and must be inspected regularly Intervals, for example, every 10 years are replaced. This is associated with additional effort and costs.

Es besteht also Bedarf, die Einsatzfähigkeit der Rettungseinrichtung in einer Windkraftanlage langfristig zu gewährleisten, um die Zeitabstände zur Prüfung zu vergrößern.There is therefore a need to ensure the operational capability of the rescue facility in a wind turbine over the long term, in order to increase the intervals between inspections.

Beschreibung der ErfindungDescription of the invention

Ausgehend von dieser Situation ist es eine Aufgabe der vorliegenden Erfindung, Mittel zur Verfügung zu stellen, die die Einsatzfähigkeit der Rettungseinrichtungen in der Windkraftanlage verlängern.Proceeding from this situation, it is an object of the present invention to make means available that extend the usability of the rescue devices in the wind turbine.

Die Lösung der Aufgabe erfolgt durch die Merkmale des unabhängigen Anspruchs. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.The object is solved by the features of the independent claim. Advantageous configurations are specified in the dependent claims.

Demnach wird die Aufgabe durch eine Rettungsvorrichtung zum langfristig sicheren Retten einer Person von einer Windkraftanlage gelöst, umfassend einen öffenbaren, gasdicht verschlossenen Behälter und eine Rettungseinrichtung eingerichtet zum Retten der Person von der Windkraftanlage, wobei die Rettungseinrichtung innerhalb des Behälters gelagert ist und der Behälter mit einem Schutzgas gefüllt ist, durch welches die Rettungseinrichtung langfristig zum Retten der Person geeignet bleibt.Accordingly, the object is achieved by a rescue device for the long-term safe rescue of a person from a wind power plant, comprising an openable, gas-tight sealed container and a rescue device set up for rescuing the person from the wind power plant, the rescue device being stored inside the container and the container having a Protective gas is filled, through which the rescue facility remains suitable for rescuing the person in the long term.

Ein wesentlicher Punkt der Erfindung liegt darin, dass die Rettungseinrichtung in dem gasdicht verschlossenen Behälter gelagert ist und der Behälter mit dem Schutzgas gefüllt ist. In anderen Worten wird die Rettungseinrichtung unter einer Schutzgasatmosphäre gelagert, die durch den gasdichten Behälter zur Verfügung gestellt wird. Mittels der derart ,konservierten' Rettungseinrichtung kann sich die Person, beispielsweise wenn auf einer Gondel der Windkraftanlage ein Feuer ausgebrochen ist, selbständig von der Windkraftanlage retten, beispielsweise abseilen.An essential point of the invention is that the rescue device is stored in the gas-tight container and the container is filled with the protective gas. In other words, the rescue device is stored under a protective gas atmosphere that is made available by the gas-tight container. By means of the rescue device that is “preserved” in this way, the person can independently save himself from the wind turbine, for example by abseiling, for example if a fire has broken out on a nacelle of the wind turbine.

Unter einem Schutzgas wird vorliegend ein Gas oder Gasgemisch verstanden, welches im Vergleich zu Luft eine andere Zusammensetzung aufweist und besonders bevorzugt im Vergleich zu Luft einen verringerten Sauerstoffanteil aufweist. Besonders bevorzugt handelt es sich beim Schutzgas um ein Inertgas oder um ein Inertgasgemisch, also ein Gas oder Gasgemisch, welches sehr reaktionsträge ist.In the present case, a protective gas is understood to mean a gas or gas mixture which has a different composition compared to air and particularly preferably has a reduced oxygen content compared to air. The protective gas is particularly preferably an inert gas or an inert gas mixture, ie a gas or gas mixture which is very inert.

Unter einem gasdicht verschlossenen Behälter wird vorliegend bevorzugt ein Behälter verstanden, der derart ausgestaltet ist, dass eine Leckagerate vorzugsweise ≤ 10-7 mbar l/s ist. Die Leckagerate ist grundsätzlich abhängig vom verwendeten Schutzgas, einer Druckdifferenz und der Temperatur und ist ein Maß für aus dem Behälter austretende Volumen- oder Masse-Einheiten des Schutzgases. Eine Leckagerate von 10-7 mbar l/s bedeutet, dass bei einem Druckunterschied zwischen einem Raum innerhalb des Behälters und einem Raum außerhalb des Behälters von 1 bar ein Verlust des Schutzgases aus dem Behälter von in etwa 1 cm3 über 100 Tage eintritt. Weiter bevorzugt beträgt die Leckagerate ≤ 10-9 mbar l/s. Die Leckagerate kann beispielsweis anhand einer Dichtheitsprüfung gemäß DIN EN 1779 ermittelt werden.In the present case, a gas-tight sealed container is preferably understood to mean a container which is designed in such a way that a leakage rate is preferably ≦10 −7 mbar l/s. The leakage rate is fundamentally dependent on the protective gas used, a pressure difference and the temperature and is a measure of the volume or mass units of the protective gas escaping from the container. A leakage rate of 10 -7 mbar l/s means that with a pressure difference between a space inside the container and a space outside the container of 1 bar, there is a loss of protective gas from the container of about 1 cm 3 over 100 days. More preferably, the leakage rate is ≤ 10 -9 mbar l/s. The leakage rate can be determined, for example, using a leak test in accordance with DIN EN 1779.

Es hat sich gezeigt, dass das Schutzgas in dem gasdichten Behälter die Einsatzfähigkeit der Rettungseinrichtung verlängert. Unter Einsatzfähigkeit wird vorliegend bevorzugt das Zeitintervall verstanden, innerhalb dessen die Rettungseinrichtung zum Retten der Person geeignet ist und die Zertifizierungs- und Sicherheitsanforderungen, insbesondere die internationale Norm für das sichere Arbeiten am Seil ISO 10333-1 bis 10333-3 und/oder die technische Regel für Betriebssicherheit TRBS 2121-3 eingehalten werden und/oder die Rettungseinrichtung die für die Rettungseinrichtung geltenden Normen erfüllt. Wenn die Rettungseinrichtung beispielsweise als manuelles Bremsgerät ausgestaltet ist, wird unter der Einsatzfähigkeit beispielsweise das Zeitintervall verstanden, innerhalb dessen das manuelle Bremsgerät die Norm EN 15151-2 erfüllt.It has been shown that the protective gas in the gas-tight container extends the operational capability of the rescue facility. In the present case, operational capability is preferably understood to mean the time interval within which the rescue device is suitable for rescuing the person and the certification and safety requirements, in particular the international standard for safe work on ropes ISO 10333-1 to 10333-3 and/or the technical rule for operational safety TRBS 2121-3 are complied with and/or the rescue facility meets the standards applicable to the rescue facility. If the rescue device is designed as a manual braking device, for example, the operational capability is understood to mean, for example, the time interval within which the manual braking device meets the EN 15151-2 standard.

Die erfindungsgemäße Rettungsvorrichtung verlängert also auf einfache Weise die Einsatzfähigkeit der Rettungseinrichtung in der Windkraftanlage und gewährleistet somit eine langfristige Funktionalität der Rettungseinrichtung. Somit trägt die Rettungsvorrichtung zu einer höheren Sicherheit von Höhenarbeitern beim Arbeiten an der Windraftanlage bei.The rescue device according to the invention thus extends the operational capability of the rescue facility in the wind turbine in a simple manner and thus ensures long-term functionality of the rescue facility. The rescue device thus contributes to greater safety for people working at height when working on the wind turbine.

Nach einer bevorzugten Weiterbildung ist eine Folie vorgesehen, in welchem die Rettungseinrichtung insbesondere gasdicht vorgesehen ist. Die Folie ist bevorzugt als Foliensack ausgestaltet und/oder die Rettungseinrichtung ist in der Folie eingeschweißt. Weiter bevorzugt ist die Folie mit Schutzgas befüllt. Insofern kann der Ausdruck, dass der Behälter mit dem Schutzgas gefüllt ist, ebenso umfassen, dass nur die Folie mit dem Schutzgas gefüllt ist. Ferner kann die Rettungseinrichtung in dem gasdicht verschlossenen Behälter gelagert sein, wobei die Rettungseinrichtung in dem Behälter zusätzlich in der gasdicht verschlossenen Folie eingeschweißt sein kann. Die Folie ist bevorzugt als homogenes Flächengebilde aus einem insbesondere dünnen Metall- oder Kunststoff gestaltet. Die Kunststofffolie kann 2 µm bis 0,5 mm Wandstärke aufweisen und/oder aus Polymer gestaltet sein. Anstelle einer Folie kann ein Schaum vorgesehen sein.According to a preferred development, a film is provided in which the rescue device is provided, in particular in a gas-tight manner. The film is preferably designed as a film bag and/or the rescue device is welded into the film. More preferably, the film is filled with inert gas. In this respect, the expression that the container is filled with the protective gas can also include that only the foil is filled with the protective gas. Furthermore, the rescue device can be stored in the gas-tight sealed container, in which case the rescue device in the container can also be welded into the gas-tight sealed foil. The foil is preferably designed as a homogeneous sheet-like structure made of a particularly thin metal or plastic. The plastic film can have a wall thickness of 2 μm to 0.5 mm and/or be made of polymer. A foam can be provided instead of a film.

Eine Rettungseinrichtung kann als Gurt, Helm, Verbindungsmittel, Halteseil, Abseilgerät, Rettungsgerät, insbesondere Rettungsgeräte mit Hubfunktion, Höhensicherungsgerät, Auffanggerät, Seil, Rettungsmittel, Bandfalldämpfer, Seilbremse, Netz, Karabiner, Anschlageinrichtung und/oder Sicherungsgerät ausgestaltet. Selbstredend können mehrere Rettungseinrichtungen in dem Behälter vorgesehen sein.A rescue device can be designed as a harness, helmet, lanyard, tether, abseiling device, rescue device, in particular rescue devices with a lifting function, height safety device, fall arrester, rope, rescue device, shock absorber, rope brake, net, carabiner, anchor device and/or safety device. Of course, several rescue devices can be provided in the container.

Bevorzugt entspricht die Rettungseinrichtung den geltenden Normen. Weiter bevorzugt wird unter Gurt ein Teil einer persönlichen Schutzausrüstung (insbesondere PSA Kategorie III) des Höhenarbeiters, der bei absturzgefährdeten Tätigkeiten am Körper getragen wird und über das Verbindungsmittel eine Verbindung zwischen dem Höhenarbeiter und einem Haltepunkt herstellt. Beim Anseilen kann der Haltepunkt beispielsweise das Seil darstellen. Die Verbindungsmittel können über das Verbinden hinaus weitere Funktionen wahrnehmen und beispielsweise einen integrierten Bandfalldämpfer umfassen.The rescue device preferably corresponds to the applicable standards. Also preferred under the harness is part of personal protective equipment (in particular category III PPE) for the height worker, which is worn on the body during activities where there is a risk of falling and which establishes a connection between the height worker and a holding point via the lanyard. When roping, the holding point can represent the rope, for example. In addition to connecting, the connecting means can perform other functions and, for example, include an integrated shock absorber strap.

Bevorzugt wird unter Abseilgerät ein mechanisches Gerät zum Bremsen eines durchlaufenden Seils verstanden. Abseilgerät finden Anwendung beim Abseilen und verfügen oftmals über eine automatische Brems- oder Blockierfunktion. Abseilgeräte, die ebenfalls zum Sichern geeignet sind und die Norm DIN EN 15151 erfüllen, werden in der Regel als Sicherungsgeräte bezeichnet.Abseiling device is preferably understood to mean a mechanical device for braking a cable running through it. Abseiling devices are used for abseiling and often have an automatic braking or blocking function. Abseiling devices that are also suitable for belaying and meet the DIN EN 15151 standard are usually referred to as belay devices.

Bevorzugt wird unter Rettungsgerät ein Abseilgerät verstanden, das über eine definierte maximale Abseilgeschwindigkeit verfügt und weiter bevorzugt mit fest verbautem Seil in verschiedenen Längen angeboten wird. Rettungsgeräte nach EN 12841 Typ C sind für die Arbeit am Seil sowie für die Rettung vorgesehen, Rettungsgeräte nach EN 341 sind als Evakuierung und Rettungsgerät zugelassen. Mit Rettungsgeräten, die über eine Hubfunktion verfügen, lassen sich verunfallte Person anheben, um sie aus der Sicherung zu befreien und anschließend abzuseilen. Weiter bevorzugt ist das Rettungsgerät geeignet für eine begleitete Personenrettung.Rescue equipment is preferably understood to be a abseiling device that has a defined maximum abseiling speed and is more preferably offered with a permanently installed rope in various lengths. Rescue devices according to EN 12841 type C are intended for work on the rope and for rescue, rescue devices according to EN 341 are approved as evacuation and rescue devices. With rescue devices that have a lifting function, the injured person can be lifted to free them from the belay and then abseil down. More preferably, the rescue device is suitable for an accompanied rescue of persons.

Das Höhensicherungsgerät ist bevorzugt Teil eines Auffangsystems, das erlaubt, sich während der Höhenarbeit innerhalb eines Aktionsradius frei bewegen zu können, und das im Falle eines Absturzes die auf den Körper wirkende Kräfte durch Brems- und Dämpfersysteme vermindert.The height safety device is preferably part of a fall arrest system that allows you to move freely within a radius of action when working at height, and that in the event of a fall, the forces acting on the body are reduced by braking and damping systems.

Auffanggeräte ermöglichen das Verstellen einer Seillänge derart, dass auch bei wechselnden Arbeitspositionen im Falle eines Absturzes ein Fallweg kurzgehalten wird.Fall arrest devices allow a rope length to be adjusted in such a way that the fall distance is kept short in the event of a fall, even when working in different positions.

Rettungsmittel dienen dem Transport einer verunfallten Person und/oder Material. Bevorzugt ermöglicht das Rettungsmittel die Rettung der Person aus einer Gefahrenlage.Rescue equipment is used to transport an injured person and/or material. The life-saving means preferably enables the person to be rescued from a dangerous situation.

Zwecks Verlängerung der Einsatzfähigkeit der Rettungseinrichtung ist vorgesehen, dass die Rettungseinrichtung ein Spinnöl-freies Seil umfasst. Beim Herstellen von Seilen werden im Spinnprozess zur besseren Verarbeitbarkeit von Fasern zu Seilen Spinnöle verwendet. Rückstände der Spinnöle an den Seilen können allerdings einen negativen Effekt auf die Einsatzfähigkeit der Rettungseinrichtung zeigen, da sich die Spinnöle durch Oxidationsprozesse abbauen. Durch Verwendung von gewaschenen Seilen, bei denen die Rückstände des Spinnöls durch Waschen vermindert worden sind und/oder durch Verwenden von Spinnöl-freien Seilen, kann die Einsatzfähigkeit der Rettungseinrichtung verlängert werden.In order to extend the usability of the rescue device, it is provided that the rescue device includes a spinning oil-free rope. When manufacturing ropes, spinning oils are used in the spinning process to improve the processability of fibers into ropes. However, residues of the spinning oils on the ropes can have a negative effect on the operational capability of the rescue system, since the spinning oils are broken down by oxidation processes. By using washed ropes, in which the residues of spinning oil have been reduced by washing and/or by using spinning oil-free ropes, the service life of the rescue facility can be extended.

Grundsätzlich können unterschiedliche Gase und/oder Gasgemische als Schutzgas verwendet werden. Eine bevorzugte Weiterbildung der Erfindung sieht allerdings vor, dass das Schutzgas ausgewählt ist aus der Gruppe umfassend Stickstoff (N2), Argon (Ar), Kohlenstoffdioxid (CO2), Distickstoffmonoxid (N2O), Schwefelhexafluorid (SF6) und/oder Mischungen davon. Wie bereits erwähnt ist die Leckagerate des Behälters und/oder der Folie grundsätzlich vom Schutzgas abhängig. Im Gegensatz zu sehr kleinmolekularen Schutzgasen wie beispielsweise Helium und Wasserstoff, welche durch kleinste Leckagen in dem Behälter und/oder der Folie hindurchdiffundieren können, haben die genannten Schutzgase den Vorteil, dass die Ausgestaltung des Behälters und/oder der Folie, um gasdicht geschlossen zu sein, geringer sind als für kleinmolekulare Schutzgase. Bevorzugt ist das Schutzgas ausgewählt aus der Gruppe umfassend Stickstoff (N2), Argon (Ar), Schwefelhexafluorid (SF6) und/oder Mischungen davon. Diese Gase zeichnen sich weiterhin durch eine einfache Handhabung aus, sind nicht brandfördernd und nicht sauer, sprich sie bilden in Wasser keine Säure.In principle, different gases and/or gas mixtures can be used as protective gas. However, a preferred development of the invention provides that the protective gas is selected from the group comprising nitrogen (N 2 ), argon (Ar), carbon dioxide (CO 2 ), nitrous oxide (N 2 O), sulfur hexafluoride (SF 6 ) and/or mixtures of them. As already mentioned, the leakage rate of the container and/or the film is fundamentally dependent on the protective gas. In contrast to very small-molecular protective gases such as helium and hydrogen, which can diffuse through the smallest leaks in the container and/or the foil, the protective gases mentioned have the advantage that the design of the container and/or the foil is closed in a gas-tight manner , are lower than for small molecular shielding gases. The protective gas is preferably selected from the group consisting of nitrogen (N 2 ), argon (Ar), sulfur hexafluoride (SF 6 ) and/or mixtures thereof. These gases are also characterized by easy handling, are not oxidizing and not acidic, i.e. they do not form acid in water.

Hinsichtlich der Verlängerung der Einsatzfähigkeit der Rettungseinrichtung und in Zusammenhang mit dem Schutzgas ist vorgesehen, dass das Schutzgas eine Spurenfeuchte von weniger als 2000 ppm v/v H2O aufweist. In anderen Worten handelt es sich beim Schutzgas um ein sehr trockenes Gas. Es hat sich gezeigt, dass insbesondere durch Vermeidung von Feuchtigkeit die Einsatzfähigkeit der Rettungseinrichtung stark verlängert werden kann.With regard to the extension of the service life of the rescue facility and in connection with the protective gas, it is intended that the protective gas has a trace moisture content of less than 2000 ppm v/v H 2 O. In other words, the protective gas is a very dry gas. It has been shown that, in particular by avoiding moisture, the service life of the rescue facility can be greatly extended.

In diesem Zusammenhang ist weiterhin vorgesehen, dass die Rettungsvorrichtung ein innerhalb des Behälters vorgesehenes Trocknungsmittel umfasst. Unter Trocknungsmittel wird bevorzugt ein Mittel verstanden, das Feuchtigkeit aufnimmt, sprich hygroskopisch wirkt, und/oder welches in der Lage ist, korrosive Gase zu binden und so eine negative Wirkung auf die Rettungseinrichtung auszuschließen oder zumindest zu verhindern. Derart kann die Feuchtigkeit weiter reduziert werden. Bevorzugt umfasst das Trocknungsmittel getrocknetes Silikagel, Phosphorpentoxid, Aluminiumoxid, Calcium, Calciumhydrid, Calciumoxid, Calciumsulfat, Kaliumcarbonat, Kaliumhydroxid, Kupfersulfat und/oder Mischungen davon. Weiter bevorzugt ist vorgesehen, dass dem Trocknungsmittel ein Wasser-Indikator zugesetzt ist, der den Erschöpfungsgrad des Trocknungsmittel angezeigt. Beispielsweis verfärbt sich der ursprünglich farblose Wasser-Indikator bei Wasseraufnahme über grün, blaugrün nach blau. Somit kann auf einfache Weise überprüft werden, ob die zur Verlängerung der Einsatzfähigkeit der Rettungseinrichtung trockenen Bedingungen eingehalten sind.In this context, it is further provided that the rescue device comprises a desiccant provided inside the container. A desiccant is preferably understood to be an agent that absorbs moisture, i.e. has a hygroscopic effect, and/or which is able to bind corrosive gases and thus exclude or at least prevent a negative effect on the rescue device. In this way, the humidity can be further reduced. Preferably, the desiccant comprises dried silica gel, phosphorus pentoxide, alumina, calcium, calcium hydride, calcium oxide, calcium sulfate, potassium carbonate, potassium hydroxide, copper sulfate, and/or mixtures thereof. It is further preferably provided that a water indicator is added to the desiccant, which shows the degree of exhaustion of the desiccant. For example, the originally colorless water indicator changes color from green to blue-green to blue when it absorbs water. It is thus possible to check in a simple manner whether the dry conditions required to extend the operational capability of the rescue facility are maintained.

Das Trocknungsmittel kann in dem Behälter und/oder in der Folie vorgesehen sein. Das Trocknungsmittel kann Kupferpartikel mit vergleichsweise großen Oberflächenstrukturen umfassen, die in einem Kunststoff-Verbund dauerhaft chemisch vernetzt sind. Ein derartiges Trocknungsmittel kann eine neutralisierte Atmosphäre erzeugen, die alle darin gelagerten Materialien vor Korrosion und Alterung schützt. Als Trocknungsmittel kann das unter dem Markennamen intercept verwendete Material verwendet werden. Das Trocknungsmittel umfasst einen sogenannten flüchtigen Korrosionshemmer, auch Volatile Corrosion Inhibitors genannt, welche Wirkstoffe transportieren, beispielsweise unter dem Markennamen EXCOR vertriebene Wirkstoffe, die den Korrosionsprozess praktisch zum Erliegen bringen.The desiccant can be provided in the container and/or in the film. The desiccant can include copper particles with comparatively large surface structures that are permanently chemically crosslinked in a plastic composite. Such a desiccant can create a neutralized atmosphere that protects all materials stored within from corrosion and aging. The material used under the brand name intercept can be used as a drying agent. The desiccant includes what is known as a volatile corrosion inhibitor, which transports active ingredients, for example active ingredients sold under the EXCOR brand name, which practically bring the corrosion process to a standstill.

Alternativ oder zusätzlich zu dem beschriebenen Wasser-Indikator ist gemäß einer weiteren bevorzugten Weiterbildung der Erfindung vorgesehen, dass die Rettungsvorrichtung einen oder mehrere an dem Behälter angeordnete Indikatoren eingerichtet zum Anzeigen einer Unversehrtheit, insbesondere eines Status, des Behälters, des Schutzgases, und/oder der Rettungseinrichtung umfasst. Der Indikator kann innerhalb des Behälters und/oder an dem Behälter insbesondere an einer Außenseite des Behälters angeordnet sein. Bevorzugt zeigt der Indikator die Unversehrtheit bzw. den Status des Behälters an, bevorzugterweise ob der Behälter geöffnet wurde, wie lange der Behälter gelagert wurde, und/oder wann die letzte Inspektion des Behälters erfolgt ist oder ob eine Inspektion notwendig ist. Weiter bevorzugt zeigt der Indikator den Status des Schutzgases an, bevorzugterweise ein Feuchtigkeitsgehalt und/oder ein Sauerstoffgehalt des Schutzgases. Weiter bevorzugt erlaubt dies zu ermitteln, ob der Behälter derart beschädigt wurde, dass der Behälter seine gasdichten Eigenschaften verloren hat. Weiter bevorzugt zeigt der Indikator den Status der Rettungseinrichtung an, bevorzugterweise, wie lange die Rettungseinrichtung in dem Behälter gelagert wurde, und/oder wann die letzte Inspektion der Rettungseinrichtung erfolgt ist. Bei dem Indikator handelt es sich bevorzugt um einen Indikator, der nicht auf eine externe Energieversorgung angewiesen ist, und/oder seine Energieversorgung autark sicherstellt. Ebenso kann der Indikator eine interne Energieversorgung aufweisen.As an alternative or in addition to the described water indicator, according to a further preferred development of the invention, the rescue device sets up one or more indicators arranged on the container to indicate the integrity, in particular a status, of the container, the protective gas, and/or the Includes rescue facility. The indicator can be arranged inside the container and/or on the container, in particular on an outside of the container. The indicator preferably shows the integrity or the status of the container, preferably whether the container was opened, how long the container was stored and/or when the container was last inspected or whether an inspection is necessary. More preferably, the indicator shows the status of the protective gas, preferably a moisture content and/or an oxygen content of the protective gas. More preferably, this makes it possible to determine whether the container has been damaged in such a way that the container has lost its gas-tight properties. More preferably, the indicator shows the status of the rescue facility, preferably how long the rescue facility was stored in the container and/or when the rescue facility was last inspected. The indicator is preferably an indicator that is not dependent on an external power supply and/or ensures its power supply autonomously. The indicator can also have an internal power supply.

Gemäß einer weiteren bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass der Behälter UV-undurchlässig, aus Kunststoff und/oder aus Aluminium gestaltet ist. Zwecks Verlängerung der Einsatzfähigkeit der Rettungseinrichtung wird bevorzugt die Rettungseinrichtung durch den Behälter vor UV-Strahlung geschützt. UV-Strahlung kann Abbauprozesse beschleunigen und beispielsweise Kunststoff spröde werden lassen. Indem die Rettungseinrichtung vor UV-Strahlung geschützt wird, kann ihre Einsatzfähigkeit verlängert werden. Der Behälter ist bevorzugt aus Kunststoff und/oder Aluminium ausgestaltet, wodurch auf einfache Weise ein Schutz der Rettungseinrichtung vor UV-Strahlung ermöglicht wird. Weiterhin haben diese Materialien den Vorteil, dass der Behälter leicht und robust ist.According to a further preferred development of the invention, it is provided that the container is made of plastic and/or aluminum so that it is UV-impermeable. In order to extend the usability of the rescue facility, the rescue facility is preferably protected from UV radiation by the container. UV radiation can accelerate degradation processes and make plastic, for example, brittle. By protecting the rescue facility from UV radiation, its service life can be extended. The container is preferably made of plastic and/or aluminum, which makes it possible to protect the rescue device from UV radiation in a simple manner. Furthermore, these materials have the advantage that the container is light and robust.

Hinsichtlich des Behälters ist bevorzugt vorgesehen, dass der Behälter als Schutzkoffer, Box und/oder Kiste ausgestaltet ist. Weiter bevorzugt weist der Behälter ein Sichtfenster auf. Ein Sichtfenster ermöglicht, dass eine Sichtprüfung der Rettungseinrichtung innerhalb des Behälters auch bei geschlossenem Behälter durchgeführt werden kann. Weiterhin hat ein Sichtfenster bei Verwendung eines Indikators innerhalb des Behälters den Vorteil, dass der Status des Behälters, des Schutzgases, und/oder der Rettungseinrichtung auf einfache Weise ohne Öffnung des Behälters überprüft werden kann.With regard to the container, it is preferably provided that the container is designed as a protective case, box and/or crate. More preferably, the container has a viewing window on. A viewing window enables a visual inspection of the rescue equipment inside the container to be carried out even when the container is closed. Furthermore, when using an indicator inside the container, a viewing window has the advantage that the status of the container, the protective gas, and/or the rescue device can be checked in a simple manner without opening the container.

Zwecks guter Handhabung ist bevorzugt vorgesehen, dass der Behälter einen oder mehrere Griffe aufweist, die ein Tragen des Behälters ermöglichen. Besonders bevorzugt weist der Behälter eine quaderförmige Form auf. Bevorzuge Abmessungen sind 55 x 35 x 24,5 cm, jeweils +/- 10%. Solche Abmessungen sind in der Handhabung besonders geeignet und ermöglichen genügend Stauraum für die Lagerung der Rettungseinrichtung.For the purpose of good handling, it is preferably provided that the container has one or more handles that enable the container to be carried. The container particularly preferably has a cuboid shape. Preferred dimensions are 55 x 35 x 24.5 cm, each +/- 10%. Such dimensions are particularly suitable for handling and allow sufficient storage space for storing the rescue equipment.

Weiter bevorzugt ist vorgesehen, dass der Behälter wiederverwendbar ist. Bevorzugt bedeutet wiederverwendbar, dass der Behälter nach erfolgtem Öffnen und Schließen weiterhin gasdicht ist. Insbesondere bedeutet wiederverwendbar, dass das Schutzgas innerhalb des Behälters nicht durch eine Einmalverpackung, die beim Öffnen des Behälters zerstört wird, zur Verfügung gestellt wird. Bevorzugt ist also nicht vorgesehen, dass eine Öffnung des Behälters und/oder der Behälter von außen mit Folie verschweißt ist.Provision is also preferably made for the container to be reusable. Preferably reusable means that the container is still gas-tight after it has been opened and closed. In particular, reusable means that the protective gas inside the container is not made available by disposable packaging, which is destroyed when the container is opened. It is therefore preferably not provided for an opening of the container and/or the container to be sealed with foil from the outside.

In diesem Zusammenhang ist gemäß einer weiteren bevorzugten Weiterbildung der Erfindung vorgesehen, dass der Behälter zum gasdichten Verschließen eine Dichtung aufweist, welche umlaufend entlang einer Öffnung des Behälters verläuft. Die Dichtung stellt auf einfache Weise sicher, dass der Behälter gasdicht und bevorzugt wiederverwendbar ist. Bevorzugt umfasst der insbesondere quaderartig ausgeführte Behälter einen Boden, eine Mehrzahl Seitenwände, die von den Seitenwänden begrenzte Öffnung und einen Deckel zum Verschließen der Öffnung. Die Dichtung kann entweder an dem Deckel oder an den Seitenwänden angebracht sein. Entweder umfasst der Behälter bevorzugt entlang der von den Seitenwänden begrenzten Öffnung eine umlaufende Dichtnut mit einem darin eingelegten Dichtelement und der Deckel eine umlaufenden Dichtrippe. Alternativ umfasst der Deckel eine umlaufende Dichtnut mit einem darin eingelegten Dichtelement und entlang der von den Seitenwänden begrenzten Öffnung verläuft die umlaufende Dichtrippe. Dichtnut und Dichtrippe sind bevorzugt derart ausgestaltet, dass die Dichtrippe in einem Zustand, in dem die Öffnung von dem Deckel verschlossen ist, in die Dichtnut eingreift und an dem Dichtelement in abdichtender Form anliegt.In this context, according to a further preferred development of the invention, it is provided that the container has a seal for gas-tight sealing, which runs circumferentially along an opening of the container. The seal ensures in a simple manner that the container is gas-tight and preferably reusable. The container, which is in particular cuboid, preferably comprises a base, a plurality of side walls, the opening delimited by the side walls and a cover for closing the opening.
