Definitions

  • the present invention relates to a cart for moving material to/from a clean room, in particular a cart with biodecontamination capacity.
  • the invention is intended in particular for use in plants comprising at least one controlled contamination zone, or clean room, i.e., an area with a very low amount of dusts and sterile from a microbiological point of view (hereinafter referred to in short as “clean room”). For this reason, the following description will make specific reference to this field of use. However, as those skilled in the art may well understand, the invention can also be usefully employed in different environments, for example in environments subject to less stringent constraints.
  • one of the problems which constantly arises in systems comprising one or more clean rooms is that of correctly managing the transport of material from an unclassified external environment or an environment with a lower classification than that of the clean room (and therefore referred to in short as “dirty space”) to a clean room.
  • the flowed transfer carts referred to as LAF Laminar Air Flow
  • LAF Laminar Air Flow
  • These carts comprise a closed compartment into which air is blown which is sucked in from the external environment, typically filtered through HEPA (High Efficiency Particulate Air) filters, and reintroduced into the external environment. A double effect is thus obtained.
  • HEPA High Efficiency Particulate Air
  • the filtered air is blown in the form of a laminar flow in order to carry out a continuous washing of the surfaces, removing any suspended pollutants from the compartment and thus preventing it from contaminating the material loaded inside the cart.
  • the material which was already clean at the start, remains clean throughout the journey, up to the second clean room.
  • pass box or material pass-through
  • the pass box can then comprise a biodecontamination system which is suitable for the treatment of the contents of the compartment.
  • the correct use of the pass box requires that, keeping the second door hermetically closed, a first operator in the dirty space opens the first door, introduces the contaminated material into the compartment and closes the first door.
  • the biodecontamination cycle is carried out, for example by means of hydrogen peroxide vapor.
  • a second operator inside the clean room can open the second door and take the material, now biodecontaminated and clean, so as to put it in the clean room without any risk of contamination.
  • Flowed LAF carts are only adapted to maintain the material at a previously achieved degree of cleanliness, but they are not capable of reducing the risk of contamination or improving the degree of cleanliness.
  • pass boxes are an expensive and inflexible solution. In fact, at least one pass box must be included for each clean room and, since it requires a rather complex and laborious installation, it is preferable for it to be provided from the beginning of the construction of the plant. In fact, the construction of a pass box requires significant masonry work and the preparation of some systems including the biodecontamination system and an adequate ventilation and air conditioning system (HVAC, Heating Ventilation and Air Conditioning). If it is necessary to create a new pass box in a location lacking one, the necessary works involve prolonged unavailability of the clean room and therefore at least partial shutdown of the entire plant.
