A dust containment apparatus includes a housing that includes an opening and defines an internal volume. A housing seal is provided along an edge of the opening for sealing the housing against a work surface to be engaged with the housing. At least two hand ports are provided in the housing for receiving a user's hands. At least one of the hand ports includes a deformable hand port seal for at least partially sealing against the user's arm or hand when inserted through the hand port into the internal volume. The deformable hand port seal includes an aperture formed therein for allowing the user's hand to access the internal volume.

A cleaning, disinfection and drying system for preparing at least one of accessory parts and/or items for washing in general, in particular in pharmaceutical production and medical technology, includes a washing chamber including an access door and in which supply devices for washing liquids and drying air are arranged on spray nozzles and washing arms with spray nozzles, wherein the washing chamber includes an isolator system and has carriers for items for washing, incoming air and outgoing air guide devices provided with filters, a glove carrier, which is arranged in a wall of the washing chamber, for gloves extending into the washing chamber configured to manipulate the item for washing located in the washing chamber, and wherein the incoming air and outgoing air guide devices are configured to maintaining a differential pressure between the washing chamber and a work area in which the system is arranged.

A device for cleaning, for example degritting or desanding, a turbomachine module comprising: (i) structure for isolating bearings of the module, by containment in a closed enclosure; (ii) structure for overpressurizing said enclosure; (iii) means for stripping material deposited in the walls of annular recesses of the module; and (iv) structure for sucking up the material thus stripped.

A portable enclosure provides a means to protect a user while performing hazardous processes upon a work piece such as grinding, sanding, drilling, painting, chemical washing, and the like. The enclosure provides a portable box-like structure having transparent plastic panels, an open-bottom portion, and a pair of glove ports. The enclosure is intended to be placed over the work piece which is positioned upon a floor surface, thereby allowing performance of hazardous processing without having to move or lift the work piece.

A washing apparatus for a 3D-printed article is provided for the removal of support material from the article. The apparatus includes a glove isolation cabinet with a liquid-discharging nozzle to enable an operator to spray an article with a washing liquid, and a drain. A first filter arrangement receives liquid discharged from the cabinet. The washing liquid drains through the first filter arrangement under the influence of gravity but the first filter arrangement is located in a trough in which washing liquid that has passed through the first filter arrangement accumulates whereby, in use, one or more filters of the first filter arrangement are submerged to ensure filtered-out residue remains submerged in the washing liquid. A pump is provided to pump liquid that has passed through the first filter arrangement through a second filter arrangement adapted to filter out solid material equal to or greater than 5 m in size.

Repairs need to be carried out on various structures in outdoor climatic conditions, which may be in wind or rain. Such a structure may be a wind turbine blade (1). This limits the time when the repairs can be conducted while conditions are within the limits set for the process. The invention provides an enclosure (4) which can be sealed to the structure so that a repair can be conducted at any desired time. The enclosure is large enough to enclose a desired work area with the operator's hands and arms entering to carry out the work through hand and arm seals (6, 7).

This invention discloses a decontaminating column for on-line replacing adsorption material, and it includes: a tank having an inner tank being used for filling the adsorption material, and one end of the tank being set to be opened; at least one discharging part is being attached to the tank, and an open-close unit by which the adsorption material can be discharged and which is installed between the discharging part and the tank. There is a chamber in the discharging part, which is connected to a gas replacement unit. At the same time, this invention also discloses a glove box. Compared with the existing technology, this invention effectively solves the problems of low efficiency, high manufacturing cost and high maintenance cost generated by decontaminating column replacement mode in the existing technology; In addition, when the decontaminating column is used in the glove box, replacing the adsorption material can ensure that the water oxygen in the glove box is prevented from leaking out and/or the water oxygen outside of the glove box is prevented from penetrating into the box.

The invention relates to a method for ground-working at a bottom of a body of water and a cleaning device for cleaning an underwater ground-working apparatus. The cleaning device has an enclosing body which extends substantially from a bottom of a body of water to above the water surface and enclosing an inner space, along which the ground-working apparatus can be moved, and a separating device, through which in the enclosing body an upper portion of the inner space can be separated off to form a cleaning area, in which the ground-working apparatus can be received and soil and contamination cleaned from it.

A port structure of a containment apparatus is capable of providing a highly reliable port by means of a structure with which a port can be formed in any size at any position and high airtightness thereof can be maintained. The port structure has: a port formation hole that is formed in a transparent synthetic resin sheet defining at least a part of a chamber; an inner ring member disposed on the inner surface side of the port formation hole; an outer ring member disposed on the outer surface side of the port formation hole; and a fastening member that joins the inner ring member and the outer ring member to each other while having a rim portion of the port formation hole held therebetween.

Decontaminating access structures that allow the partial insertion of decontamination tools into glove boxes and the like to easily and safely decontaminate harmful materials are provided.
