Can we look at the light through a glass door from another room? I have glass dividers in between the operators. Can I continue working while the UVC lamp is on in another room?

UVCs are very high-energy lamps with a shorter wavelength, but they lose energy faster than UVAs and UVBs.

Similarly, it cannot even cross normal glass. It loses its energy.

You can look at it through the glass door or the wall safely. Essentially, the light that passes through the glass is blue light minus UVCs.
