Correct use of ultraviolet disinfection lamp

1. The ultraviolet light source cannot directly illuminate the human body. Also, do not look directly at the ultraviolet light source. Should wear protective glasses or sunglasses when operating ultraviolet disinfection lamp, because ultraviolet irradiation may cause skin erythema, eye conjunctiva stimulation and easy to fatigue; Ultraviolet disinfection process will produce a certain amount of ozone, should be in the end of disinfection immediately after the window ventilation.

2. Install ultraviolet equipment in a standard way. Ultraviolet disinfection lamp disinfection usually USES ultraviolet ray with wavelength of 253.7nm to sterilize. There are certain requirements for the use of space and height, and the sterilization effect should be better if the ultraviolet disinfection lamp is installed in the irradiation range of 1.8m to 2m high and 1.2m around the ground.

3. When using ultraviolet disinfection, the control switch should be independently separated from the lighting switch, and marked with a clear warning label, the installation height should be higher than the general lighting is appropriate, the control can be used timing control, or increase the human body sensor, the light to ensure the safety of the use of ultraviolet disinfection lamp, to avoid accidents.

4. In order to ensure the ultraviolet radiation intensity and effect, the surface of the ultraviolet disinfection lamp should be kept clean. In use process, should keep the surface of antiseptic ultraviolet disinfection lamp clean, if discover lamp tube surface has dirt, grease, answer to turn off power in time shut down wipe, the ultraviolet disinfection lamp that suggests frequent use needs to be wiped with 75% alcohol every week; When indoor air is disinfected with ultraviolet disinfection lamp, the room should be kept clean and dry to reduce dust and water mist. The irradiation time should be appropriately extended when the temperature is lower than 20℃ or higher than 40℃ and the relative humidity is more than 60%.

5. Calibration of ultraviolet intensity meter (intensity test) at least once a year. Specific parameters please consult manufacturers and dealers.

Method of measuring the intensity of ultraviolet disinfection lamps

The ultraviolet disinfection lamp tube in use should be in 3 ~ 6 months with ultraviolet radiation illuminance meter to make an intensity detection, with ultraviolet radiation illuminance meter to make a measurement calibration, in order to maintain accuracy, find the ultraviolet disinfection lamp tube with unqualified intensity should be replaced in time.

We do it by chemical indicator CARDS

1. After opening the ultraviolet disinfection lamp tube for 5 minutes, place the chemical card at a vertical distance of 1 meter under the ultraviolet disinfection lamp, with the patterned side of the chemical indicator card facing up;

2. The ultraviolet disinfection lamp is irradiated for 1 minute (the chemical card will have different color changes);

3. Observe the color block of the indicator card and compare it with the standard color block, then read the irradiation intensity.

The test results take 10w as an example:

1. The new ultraviolet disinfection lamp shall be qualified if its ultraviolet illumination is not less than 30uw/cm;

2. If it is the ultraviolet disinfection lamp tube in use, it should not be less than 20uw/cm to be qualified.

Usages of ultraviolet disinfection lamp

1. Ultraviolet disinfection lamp device: every 10 meters can be installed 38 watt of ultraviolet lamp tube, useful interval does not exceed two meters. Together, it is necessary to equip indoor temperature and moisture meters. Ultraviolet disinfection lamp should be careful to use.

2. When used for air disinfection should be closed doors and Windows, since the light is bright 5-7 minutes after the timing, each disinfection time shall not be less than 60 minutes, ultraviolet disinfection lamp shine in the process to stop the personnel into the room, it is necessary to enter, should first stop ultraviolet disinfection lamp shine, especially young unmarried lady remember this.

3. With ultraviolet disinfection lamp disinfection article, the article spread out or hang, expand shining surface, useful interval is one meter, shine 30 minutes or so can.

4. When using ultraviolet disinfection lamp, should insist on the cleanliness of the environment, the air can not have dust and water mist, etc., when the indoor temperature is lower than 20 degrees Celsius or the relative humidity exceeds 50%, should extend shining time. After scrubbing the ground to wait on the ground after the dry ultraviolet lamp disinfection.

5. Ultraviolet disinfection lamp tube appearance should adhere to clean, no dust, weekly with 95% ethanol cotton ball scrub, and better records.

6. Ultraviolet to human skin mucous membrane is bound to harm, the use of ultraviolet disinfection lamp to pay attention to do a good job of protection, the eyes can not direct at the ultraviolet light source, otherwise the eyes will be damaged.
