Yes, absolutely 100% Safe!
SpaceUV systems complies 100% with Strict Occupational Safety Norms established by US-NIOSH, US-CDC, ASHRAE and as required by UNE:00068, IEC 62471 & ISO 15858 global safety standards of human exposure to artificial optical radiation.
As per IES Photobiology Committee, upper-room UVGI (ie technology used in SpaceUV) is the safest, most effective application of UVC for disinfection applications. A average 15 min UV exposure from Solar radiation in Maharashtra is lot more than 10 hours of continuous exposure to stray UVC from SpaceUV!
SpaceUV technology has been tested by Dept of Biosciences & Bioengineering at IIT Bombay with over 114 triplicated high resolution UVC irradiance measurements, concluded that both average as well as the maximum stray UVC generated by SpaceUV in the human occupied space is lower than the required UVC safety limit established by ASHRAE, NIOSH, UNE:00068, IEC 62471 & ISO 15858.
To limit the UVC intensity in the lower room(i.e. human occupied spaces)to a safe level, all SpaceUV upper room UVGI systems are designed with use of most advanced Raytracing simulations & tested with high resolution UVC meters designed for evaluation of Occupational Safety hazards.
During normal use, the UVC irradiation on people around device is way below allowable regulatory threshold limits of 0.2µW/cm² as published by US-NIOSH, US-CDC, ASHRAE and as required by UNE:00068, IEC 62471 & ISO 15858.
