  • Clean rooms are used in many fields such as electronics, micromechanics, optics, nanotechnologies and biotechnologies, pharmaceuticals, sterile compounding processes in pharmacy, medical equipment or even in the food industry.
  • clean rooms must be supplied with large quantities of air filtered by high efficiency filters to dilute and remove particulates, bacteria and chemicals inside the room. Air is also used to pressurise the room and ensure that no contaminated air enters the clean room.
  • clean rooms must be constructed with materials chosen specifically because they do not generate contaminants, particulates or chemical fumes and the materials must also be easy to clean.
  • the people i.e. operators working inside clean rooms, must wear and carry specific garments, accessories, equipment and tools to minimise the dispersion of micro-organisms and the particulates that they in turn generate such as hair, skin particles and clothing fibres.
  • the document WO2005065476 describes a protective or work overall used in dangerous conditions involving heat, fire, cold, etc.

  • This pouch comprises two openings: one upper opening and one lower opening.
  • the sleeves of the overall become inverted inside the pouch when the operator passes their hands through, first, the lower opening and, second, the upper opening so the sleeves are pulled inside the pouch through the upper opening. The operator will then lift their legs into the pouch via the upper opening and the closed pouch.
