UV disinfection
one particular. Air disinfection
approach:
1) Do a good job involving environmental cleaning together with sterilizing before diffusion and disinfection to steer clear of employees taking walks.
2) The number of installed ultraviolet (uv) lamps is on average ≥1. 5W / m⊃3; that is definitely, at least one 30W ultraviolet disinfection lamp is required for every 30 square meters of space.
3) Diffusion time ≥30 minutes, close doors, glass windows, and fluorescent lamps throughout irradiation, the operator should take personal protection, avoid direct eyes of the AND ALSO light, leave immediately following turning about, avoid employees entrance.
4) After this irradiation and disinfection, the staff members will enter into after about half an hr associated with ventilation.
2. Surface disinfection
