Nursing homes normally use these kinds of ultraviolet lamps for the disinfection connected with air and exterior of objects.
UV disinfection
first. Air disinfection
approach:
1) Do a good task involving environmental cleaning plus you could before irradiation in addition to disinfection to steer clear of workers taking walks.
2) The amount of installed ultraviolet (uv) bulbs is on average ≥1. 5W / m⊃3; that is certainly, at least one 30W ultraviolet disinfection lamp is required for every 30 square meters of living space.
3) Diffusion time ≥30 minutes, close doors, windows, and fluorescent lamps during irradiation, the operator is going to take personal protection, avoid primary eyes of the AS WELL AS lamp fixture, leave immediately right after turning about, avoid staff entry.
4) After the irradiation and disinfection, this personnel will get into immediately after about half an hour involving ventilation.
2. Exterior disinfection
method:
1) That is best to make use of a new mobile ultraviolet disinfection bulb for short-distance irradiation, or maybe an ultraviolet-ray lamp fixture for suspended irradiation. Little goods can be positioned in an ultraviolet (uv) sanitation box for irradiation.
2) When sterilizing tough surfaces such as paper together with material with ultraviolet lighting, the irradiation time needs to be properly extended, and both sides should be uncovered.
Safeguards
1. Do not permit ultraviolet rays in order to instantly irradiate eyes plus skin area to avoid injuries.

minimal payments Dispel rumors!
Recently, one can find rumors: "Ultraviolet disinfection light can be used to get skin disinfection"?
This is usually a rumor!!!
The harm of ultraviolet disinfection light fixture to the human body is mainly demonstrated within two aspects:
