Use and precautions of ultraviolet disinfection lamp

Ultraviolet rays can kill various microorganisms, including bacterial propagules, spores, mycobacteria, viruses, fungi, rickettsiae and mycoplasma, etc., all surfaces, water and air contaminated by the above microorganisms can be disinfected with ultraviolet light.

Precautions for use:

1. Ultraviolet rays can only propagate along a straight line, have weak penetration ability, and can only kill directly irradiated microorganisms. Any paper, lead glass, plastic will greatly reduce the intensity of irradiation. Therefore, as far as possible, the disinfection site should be fully exposed to ultraviolet rays.

2. The penetration of ultraviolet rays is weak. The dust and oil stains attached to the surface of the lamp tube will directly affect the irradiation intensity of the ultraviolet disinfection lamp. Therefore, the lamp tube can be wiped with alcohol cotton balls or gauze every 1 to 2 weeks to maintain the ultraviolet rays. Clean the lamp.

3. Indoor air disinfection: requires no less than 1.5W per square meter, irradiation time no less than 30min, and lamp tube less than 2m from the ground. The room should be kept clean and dry to reduce dust and water mist. When the temperature is lower than 20℃ or higher than 40℃, and the relative humidity is higher than 60%, the irradiation time should be properly extended.

4. Object surface disinfection: The lamp tube should not be more than 1 meter away from the surface of the object. The irradiated surface should be directly irradiated, and a sufficient dose of radiation should be reached (100000UW.s/cm² when killing bacterial spores)

5. When using ultraviolet lamps to irradiate and sterilize, no one should be present, to avoid injuries caused by ultraviolet rays directly irradiating people's eyes and skin, and do not look directly at the lighted lamps.

6. In places where there are personnel activities, generally do not use ozone lamps, because ozone will promote the coagulation of the human hemoglobin, resulting in insufficient oxygen supply to the body, dizziness, nausea, affecting the health of the body, especially when the ozone concentration reaches >0.3ppm (mg/m²), it will cause harm to the human body.

7. Ultraviolet rays have a killing effect on organic cells, please do not irradiate pets and plants for a long time.

8. Do not use the UV lamp as a lighting lamp. The disinfection time is preferably 30 minutes to 1 hour. It is not recommended to turn on the UV lamp for a long time.

9. After disinfecting the room, please open the window and ventilate for more than 5 minutes.

10. The general life of the lamp is 1000 hours. The radiation intensity is monitored every six months, and it should be replaced when it is less than 70uw/cm².

11. Do not put damaged or worn lamps next to people or throw them into places with water to avoid polluting the water source.
