Hospitals usually use these kinds of ultraviolet light bulbs for the disinfection regarding air and exterior associated with objects.
one. Air disinfection
1) Do a good job connected with environmental cleaning and sterilizing before diffusion and disinfection to keep away from personnel taking walks.
2) The range of installed ultraviolet (uv) lighting fixtures is on average ≥1. 5W / m⊃3; which is, at least one 30W ultraviolet disinfection lamp can be required for every twenty square meters of area.
3) Irradiation time ≥30 minutes, close doors, house windows, and fluorescent lamps while in irradiation, the operator should take personal protection, avoid primary eyes of the UV lamp, leave immediately soon after turning with, avoid workers entrance.
4) After typically the diffusion and disinfection, often the employees will key in immediately after about half an hr regarding ventilation.
2. Surface area disinfection
1) The idea is best to use some sort of mobile ultraviolet disinfection lamp for short-distance irradiation, or an ultraviolet-ray light fixture for suspended irradiation. Small objects can be placed in an ultraviolet sanitation box for diffusion.

second . Dispel rumors!
Recently, one can find rumors: "Ultraviolet disinfection bulb can be used to get skin disinfection"?
This is a rumor!!!
The hurt of ultraviolet disinfection lamp fixture to the human body is mainly manifested in two aspects:
