DE4134486A1 - Box for disposing of dangerous material - has arm holes fitted with sleeves and means to maintain internal vacuum - Google Patents

Abstract

Material which contains asbestos fibres which can be a danger to health, is disposed of using a box (1).This has a base frame (2), and walls (3) and longitudinal walls (4) which together form a sealed housing. One side wall has two arm holes fitted with sealed sleeves which are fitted with gloves at their free ends. One end wall is provided with openings for access to the interior. The opposite end has an opening (6) for connecting to a vacuum source to maintain a sub-atmospheric pressure in the container when the openings (7, 8) are sealed. USE/ADVANTAGE - Dangerous material can be disposed of without risk to the operator.

Description

The invention relates to a device for disposal and Foreclosure of small, contaminated devices and objects from poisoned ingredients, e.g. B. from weak and / or festge bound asbestos-containing materials.

In recent years, many public and pri vaten buildings small disposal measures such. B. Asbestos care work on night storage heaters. There so far only a small part of the devices or Ge to be disposed of objects must be increased in the future Workload can be expected.

According to the prior art, the following are so far known methods:

The item that has not yet been disposed of will be removed carried out without special protective measures. Is also known the packaging of the compact device in construction film, which at Transport prevents and is easily destroyed. By both Methods often require a bulky, heavy weight body longer distances are transported. In the event of damage from the Transport can release dangerous substances and thus the Environment. The final disposal must then take place at a central point.  

Disposal at the previous Ge location is also known advises or object. By building a walk-in Partitioning with negative pressure over the body to be disposed of arises for the occupancy that is complete in this room personal protective equipment required, the required Work room, a people and material lock would have to existing, but is used very rarely. Through the soiled work clothes can contaminate the Environment cannot be excluded. The creation of this closed working chamber and especially with locks function is time consuming, especially compared to that low workload for the disposal of the to be renovated Small appliance. It should be borne in mind that a large part of the built chamber mostly not in another place is reusable.

The facts listed above mostly lead to how initially described, complete, not disposed of devices and Ge to transport objects to a collection point and the to ignore any dangers that may arise.

Based on the aforementioned prior art, the Invention based on the task in the shortest possible time spent a contaminated object against the outside world to safely seal off a small, inaccessible hood that All necessary remedial work permits that easily can be dismantled and / or folded again at another point Use and personal protective equipment for saves the disposal companies working with it.

The device for disposal and isolation of small devices and objects, in which the aforementioned task is solved, is characterized in that in a compact, easily transportable and disassembled vacuum isolation box ( 1 ) the necessary disposal measures without personal protection equipment from the outside be performed.

The size and design of this box ( 1 ) is adapted to the external dimensions and the position of the body to be disposed of. We are thinking of various coarsely graduated sizes that can be fully slipped on or pushed against a vertical boundary if there is no rear wall. The latter would be e.g. B. often required for asbestos care work on night storage heaters.

All different types of vacuum bulkhead boxes ( 1 ) consist of a base frame ( 2 ), the front, stable, non-transparent panels ( 3 ) and the long side, transparent walls ( 4 ), the disassembly and assembly can be carried out with little time and that are easy to carry and reusable.

In order to be able to produce the required negative pressure, all open side walls of the box ( 1 ) must be sealed airtight with a seal ( 9 ) in relation to the contact surfaces and design-related air slots. This is guaranteed by sturdy adhesive strips.

The disposal work within the vacuum bulkhead box ( 1 ) is guaranteed by at least one pair of flexible, long-sleeved work gloves ( 5 ) that are firmly attached in the clear casing and sealed. It can be used to visibly reach every point in the renovation room and all necessary work can be carried out.

In the stable end faces, the connection for the negative pressure maintenance ( 6 ) and opposite at least one rectangular and a circular disposal opening ( 7 and 8 ) are introduced. The latter allows loosened plates as well as fine to coarse-grained materials to be transferred to the connectable disposal containers under negative pressure and sealed. The removal in these containers is safe and easy to carry out.

After the main disposal work has been completed, the remaining fibers are bound inside the box ( 1 ) and on the remaining parts of the small device. The vacuum bulkhead box ( 1 ) is then dismantled and transported to the next point of use. The remaining part of the disposed device can be dismantled as far as possible and can be safely transported with significantly smaller transport dimensions and weights.

All disposal work is carried out without personal protective equipment for the workforce. The vacuum bulkhead box ( 1 ) guarantees simple, quick, safe and inexpensive operation.

There are now various possibilities for developing and designing the vacuum isolation box ( 1 ) according to the invention, for which reference is first made to claim 1 and the claims that follow it.

In the following, an off is given in connection with the description management example explained with reference to the drawing, which in scheme table shows a negative pressure bulkhead box.

The vacuum isolation box ( 1 ) shown with an open rear wall is, for. B. suitable for the disposal of night storage heaters. It is pushed over the object to be disposed of ( 10 ) and sealed airtight by a seal ( 9 ) on the floor and on the rear wall for the purpose of maintaining negative pressure. The vacuum bulkhead box ( 1 ) consists of a stable base frame ( 2 ), opaque panels on the front ( 3 ) and transparent walls on the long side ( 4 ). At least two = 1 pair of flexible, sleeveless work gloves ( 5 ) are securely attached in the see-through sheath ( 4 ).

The stable end faces ( 3 ) are provided on the one hand with the connection for maintaining the vacuum ( 6 ) and on the other hand with at least one rectangular and circular disposal opening ( 7 and 8 ).
