Methods and systems for on-site, continuous generation of peracid chemistry, namely peroxycarboxylic acids and peroxycarboxylic acid forming compositions, are disclosed. In particular, an adjustable biocide formulator or generator system is designed for on-site generation of peroxycarboxylic acids and peroxycarboxylic acid forming compositions from sugar esters. Methods of using the in situ generated peroxycarboxylic acids and peroxycarboxylic acid forming compositions are also disclosed.

A device capable of stably obtaining gas of a sterilizer containing hydrogen peroxide for a long time is provided. A cleaning device that cleans a heating surface that gasifies a sterilizer of a gasifier for a sterilizer is provided, and after an operation for a fixed time period, the heating surface is cleaned.

Provided is an air cleaning system including: an ozone generation unit that generates ozone gas; and a discharge unit that atomizes or vaporizes an aqueous alcohol solution and discharges the aqueous alcohol solution. A mole fraction of an alcohol included in the aqueous alcohol solution with respect to the aqueous alcohol solution is 0.05 or more and 0.35 or less. A hydroxyl radical is generated through a reaction of the ozone gas with the aqueous alcohol solution that has been atomized or vaporized.

System and method to reduce risk of patient infections (HAI), using operating rooms (chambers) equipped with suitable automatic airborne sterilizing agent generators, sensors, mechanisms, automatic air control devices, and laminar flow devices. After suitable safety checks, the system isolates the interior air from external air, and activates an air phase anti-microbial agent generator, filling the room with an air-phase anti-microbial agent. After sterilization, the invention deactivates the generator then restores the connection to outside sterilized air. The chamber also comprises an intelligent platform comprising video cameras, and computer vision systems configured to identify humans and medical supplies, read optical tags, and correlate recognized objects with RFID tag data. The intelligent platform can be configured to automatically detect and warn on conditions associated with a high risk of HAI, optimize the sterility of the chamber, automatically detect other operating room issues, and interface with outside computerized medical databases and facilities networks.

An eyeglass device for inactivating a pathogen includes an eyeglass frame connectable with a face of a person and a pair of lenses connected with the eyeglass frame. The pair of lenses includes a composition that blocks some wavelengths of beams of ultraviolet light. The eyeglass device further includes a light affixed to the eyeglass frame and that emits an ultraviolet light beam having a wavelength of about 205 nm to about 225 nm and does not emit an ultraviolet light beam having a wavelength of about 254 nm. Methods of inactivating a pathogen are also described.

Apparatus, methods and instructions for disinfecting air. The apparatus may include, and the methods may involve, a fixture. The fixture may include a germicidal light source. The fixture may include a fan. The fan may circulate air through a volume into which the germicidal light source propagates germicidal light. The light source may be configured to emit, upward from a horizontal plane, a beam that, absent reflection off an environmental object, does not cross the horizontal plane. The apparatus may include a shield that prevents light from the light source from crossing the horizontal plane. The sensor may face upward from the horizontal plane. The sensor may face downward from the horizontal plane.
