The following protection requirements shall be observed when using ultraviolet germicidal lamp
Ultraviolet germicidal lamp is mainly used for air disinfection in hospitals, infectious disease hospitals, baby rooms, nurseries, operating rooms, dressing rooms, laboratories and pharmaceutical factories. The area to be disinfected is required to have an irradiation intensity of 32uW per square centimeter, at least for 1 hour, while the number of ultraviolet germicidal lamps is determined by the room area. Ultraviolet germicidal lamps mainly rely on 253.7 nm short wave ultraviolet radiation to sterilize and disinfect. In addition, some lamps also radiate 185 nm ultraviolet radiation, which will produce ozone in the air and have the function of sterilization.
Nowadays, families like to use ultraviolet disinfection lamps to ensure indoor safety. However, ultraviolet radiation is harmful to people, so strict protective measures and corresponding regulations must be taken in order to ensure reasonable application. According to experience, the following protection requirements are obtained:
1. During air disinfection, a 30 watt lamp shall be installed every 10-15 square meters. The lamp shall be at least 2.5 meters away from the ground, and the exposure time shall be more than 30 minutes each time;
2. When disinfecting the surface of an object, the distance between the lamp position and the object to be disinfected shall be less than 1 m, and each exposure time shall be at least 30 minutes;
3. When it is used for drinking water disinfection, the thickness of the water layer shall be less than 2 cm, the ambient temperature for disinfection shall be controlled at 20 ℃~40 ℃, and the humidity shall be controlled at 40%~60%. It is better to use it in the unattended state;
4. The intensity of ultraviolet germicidal lamp shall be monitored every half a year, and the new lamp shall be higher than 100 μ W/cm2, when the lamp is used for more than 1000 hours, it shall be replaced with a new lamp.
