Aprovechando La Luz Ultravioleta Para La Desinfección De Oficinas: Beneficios Y Precauciones


Ultraviolet light belongs to a kind of electromagnetic radiation, a kind of invisible light. UV light has been used for disinfection for nearly a hundred years, and is an economical, practical, effective, easy to use and safe disinfection method. This article will introduce the use of UV light for office and precautions.

Characteristics of UV Light for Office

The germicidal spectrum of ultraviolet light is wide and can kill the respective microorganisms, including bacterial spores, bacterial propagules, viruses, tuberculosis bacilli, fungi and rickettsiae. UV disinfection of object surface is affected by the medium, and is not suitable for the disinfection of object surface with complex shape and roughness. UV light and alcohol compounds or hydrogen peroxide synergistic effect, can improve the role of killing microorganisms. According to the sterilization intensity of ordinary ultraviolet germicidal lamps and high-intensity ultraviolet germicidal lamps. High-intensity ultraviolet germicidal lamp than ordinary ultraviolet germicidal lamp intensity of more than 1 times. 5 ~ 10s of irradiation on the virus, spores and bacterial spores of the killing rate of up to 99.9%.

The use of UV light for office

  • Direct irradiation method can be used hanging or mobile UV light for office for irradiation. Lamp height from the ground 1.8 ~ 2.2m, continuous irradiation of not less than 30min. Place the UV lamp according to an average of not less than 1.5W per cubic meter of space.

  • Indirect irradiation method using closed ultraviolet sterilizer such as circulating wind ultraviolet sterilizer for indoor air disinfection. This method is not only reliable disinfection effect, but also can be used in the case of people, boot 30min can achieve disinfection qualified.

Precautions for the Use of UV Light for Office

  • In the process of use, should keep UV light for office surface clean. Wipe with alcohol gauze once a week. When the surface of the lamp is found to have dust and oil, it should be wiped at any time, so as not to affect the penetration and not to achieve the disinfection effect.

  • When using ultraviolet light to disinfect the surface of articles, the irradiated surface should be subjected to direct irradiation of ultraviolet light, and should reach a sufficient irradiation dose.

  • The UV light source should not be allowed to irradiate people, so as not to burn the eyes and skin.

  • When determining the intensity of ultraviolet light, the voltage 220V ± 5V, temperature 20 ℃ ~ 25 ℃, relative humidity <60%, ultraviolet intensity meter at least once a year calibration.

  • When using UV light for office space to disinfect and sterilize the room, doors and windows should be closed, and after disinfection, windows should be opened immediately for ventilation.
