Abstract: The invention relates to a new mask for the protection against biological agents having additional features to improve the efficiency. The mask is in particular equipped with a filtering layer providing outstanding performances against biological agents, with a high efficiency exhalation valve and with a boundary sealing layer to enhance the seal between mask and face.

Abstract: The invention refers to a personal protective equipment for the respiration that is made up of an upper (1) and a lower (2) part characterized in that the two parts are both flat and exactly identical, are circle-shaped with a straight edge and a curved one, arc-shaped, and are linked together through the curved edge (3). The equipment can be re-positioned in a folded position for storage, while during the use, it creates an air-chamber, crescent shaped, over the nose and the mouth of the user, and the linear edges of the two parts are in contact with the face. The protective equipment of the invention, thanks to its small size, high comfort and high sealing along its perimeter, is particular effective in the applications where a high tightness is required for high protection level such as the use to protect against biological agents.

Abstract: New testing methodology for the evaluation of the protection of the Personal Protective Equipments (PPE) for the respiratory tract against biological agents, characterized in that different machineries are used to reproduce the usage of the PPE, simulating a breathing through the Sheffield's head and self-respirator. The apparatus consists of: a) a viral and/or bacterial aerosol generator b) a test chamber containing the Sheffield's head c) a respirator simulating breathing and adjusting the inspiration and expiration frequency d) a suction system delivering the samples of air withdrawn in different points to the bubblers to determine the viral and/or bacterial concentrations.

Abstract: The invention relates to overalls, manufactured by polypropylene and polyethylene, usable as protective clothing, in particular suitable as barrier against biological agents. The overalls provide a very high level of protection against the penetration of liquids and microorganisms, excellent mechanical properties, including tear and abrasion resistance, outstanding softness, drapeability and comfort.

Abstract: The invention refers to a filtering system composed by a face mask and a filter against biological agents, joined together by a new connector. The connector joins the filter to the mask in an easy, fast and affective way. The filtering system provides a very high barrier against biological agents, a high seal and is very easy to use.

Abstract: The invention relates to clothing, manufactured by polypropylene and polyethylene, usable as a partial protection of the body, in particular suitable as barrier against biological agents. The clothing provides a very high level of protection against the penetration of liquids and microorganisms, excellent mechanical properties, including tear and abrasion resistance, outstanding softness, drapeability and comfort.
