Description

The invention relates to a decontamination solution for decontamination and its use, and to a decontamination set.

Decontamination is the decontamination, decontamination, or inactivation of an object or area. For example, a person or an object, thus a vehicle or a building, comes into consideration as an object. Contamination or poisoning is caused by an atomic, biological and/or chemical warfare agent. The warfare agent is inactivated by the decontamination. Decontamination solutions that are used for decontamination are already known.

The invention is based on the object of designing a novel decontamination solution in such a way that its decontamination effect with regard to certain warfare agents is increased. In addition, the object of the invention is to design a decontamination set in such a way that the decontamination solution can be stored for as long as possible.

The object is achieved according to the invention in that the decontamination solution contains the components water, in particular demineralized water, and chloramine T, with chloramine T in a concentration of 1-10% or 1-7.5% or 2-7.5% or 2 - 5% based on the total mass. The total mass is the mass of the decontamination solution. Surprisingly, chloramine T is particularly effective for decontaminating objects or areas that have been contaminated by a chemical warfare agent from the Loste group of substances or by the warfare agent sarin.

The object is also achieved by using the decontamination solution as described for decontamination and is correspondingly advantageous according to the invention.

In addition, the object is achieved in that the decontamination set for the decontamination solution described has a cover, with separating chambers being provided within the cover, with at least two components of the decontamination solution being stored in different chambers, with the chambers being destructible together in such a way that the Mix the decontamination solution components inside the wrapper. In this way, the shelf life of the decontamination solution can be significantly increased, since it is only prepared shortly before use. A shelf life of up to 4 years is typical.

For example, if you mix chloramine T with water, chlorine gas is formed. The chlorine gas evaporates quickly. Due to the storage of water and chloramine T in separating chambers, the two cannot initially react with each other. Rather, they are only mixed after the destruction of the chambers and then react. This applies accordingly to all other components that are stored in different separating chambers.

It can also be advantageous if the decontamination solution also contains the component ascorbic acid, in particular in a concentration of 1-35% or 5-30% or 10-25% or 15-20% based on the total mass. The ascorbic acid dissolves only gradually, typically within 15 minutes. In this respect, it is initially present as an acid, which has a decontaminating and therefore inactivating effect. After the acid is dissolved, it is neutralized by the basic chloramine T. Then the acid loses its caustic effect. The pH is then adjusted and regulated. Typically, it is set to 4.8, which means it is regulated.

Furthermore, it can be advantageous if the decontamination solution also contains the component toluidine blue as a dye, in particular with a concentration of 0.025-1% or 0.05-0.75% or 0.5% based on the total mass. This dye is easily recognizable so that it is easy to check the area decontaminated with it. Toluidine blue is also an antidote, i.e. an antidote to poisons, toxins, drugs or other substances that affect an organism. Toluidine blue has a decontaminating effect on hydrocyanic acid, which it effectively combats.

Accordingly, the use of toluidine blue makes sense to counteract cyanotoxicity.

It can also be advantageous if the decontamination solution contains a surfactant as a component. A washing-up liquid can be used as a surfactant. The use of a surfactant reduces the surface tension of the surface to be decontaminated. In this way, the decontamination effect is significantly improved. If the solution is placed on a solution carrier, for example, the surface to be decontaminated is cleaned more effectively when wiped with it.

It can advantageously be provided that the decontamination solution does not contain any other components. This particularly emphasizes the effect of the individual components.

It can also be advantageous if the chloramine T and/or the ascorbic acid and/or the toluidine blue on the one hand and the surfactant on the other hand are stored in different chambers. Due to the accommodation in different separating chambers, the components do not react with each other. A distinction can be made between solid components and liquid components.

In addition, it can be advantageous if the chloramine T and/or the ascorbic acid is stored as a dry substance, in particular in powder form. The same applies to the dye or toluidine blue. As a dry substance, the components are more durable and lighter.

Furthermore, it can be advantageous if a solution carrier for holding the decontamination solution is stored in a chamber, with the solution carrier being a sponge, a pleated flow sponge and/or a cloth in particular, with the toluidine blue in particular being applied to the solution carrier. The solution carrier soaks up the decontamination solution and absorbs it. Since the solution carrier initially remains in the cover after the chambers have been destroyed, the decontamination solution is completely absorbed. A sponge and in particular a flow sponge, but also a cloth can absorb as much of the decontamination solution as possible.

After the individual chambers with the different components have been destroyed, the components have mixed and been absorbed by the solution carrier and the solution carrier has been removed from the envelope, the surface of the object or area to be decontaminated can be wiped with the solution carrier.

It can be advantageous if the surfactant is dissolved in the water and they are stored together in a common chamber. As a result, the durability is not adversely affected and to this extent the decontamination set can be designed more simply, since it has one less chamber.

Further advantages and details of the invention are explained in the patent claims and in the description and shown in the figures. It shows:

• 1 a basic sketch of the decontamination set in cross section;
• 2 a basic sketch of the decontamination set in cross section.

The decontamination set 1 after 1 has an envelope 4 within which a first chamber 4.1 and a second chamber 4.2 are formed by using a membrane 4.3. A liquid decontamination solution carrier 3.2, such as water, is contained within the first chamber 4.1 as a component of the decontamination solution. The membrane 4.3 is designed as a water cushion, which is placed inside the cover 4. The solution carrier 2, such as a sponge, is contained in the second chamber 4.2. Also contained in this second chamber 4.2 as a further component is a decontamination base material 3.1 in the form of a solid such as chloramine T and/or ascorbic acid in the form of a salt. Within the decontamination solution carrier 3.2 is also advantageously contained a surfactant 6, which is added or dissolved in the water 3.2. Toluidine blue is also contained as a dye 5 in this second chamber 4.2. Alternatively, the dye 5 can also be provided in the first chamber 4.1 together with the surfactant.

The closed cover 4 is preferably vacuumed, so that the sponge 2 is at least partially compressed.

According to example 2 the membrane 4.3 was destroyed by external force exerted by the user. Thus, the liquid decontamination solution carrier 3.2, and therefore the water, is drawn into the solution carrier 2, and consequently the sponge or absorbed by the sponge. The same applies to the surfactant 6 as part of the water 3.2. By absorbing the water 3.2, the basic decontamination substance chloramine T 3.1, which is present as a salt, is dissolved. Together with the water 3.2, the chloramine T 3.1 forms the desired disinfectant 3 in the desired dosage, depending on the mass of chloramine T 3.1 in solid form on the one hand and water 3.2 on the other. The dye 5 is also dissolved or distributed in the water.

The absorption of the water 3.2 by the sponge 2 reduces the internal volume within the cover 4 somewhat so that it can be crushed, so that the disinfectant 3 can be mixed and distributed within the sponge 2 quickly and easily.

After the envelope 4 has been opened, the soaked sponge 2 can now be used to disinfect surfaces. This releases the liquid stored in it, and therefore the colored disinfectant 3, by wiping or pressing.
