What if the door of ultraviolet disinfection cabinet is transparent?

What should I do if the ultraviolet disinfection cabinet cracks? According to relevant data, ultraviolet rays have bactericidal effect, and the wards of hospitals are all disinfected with ultraviolet rays. However, too strong ultraviolet rays will do harm to the human body, so we should do a good job of protection. Glass, oxygen in the atmosphere and ozone layer in the sky all have a strong absorption effect on ultraviolet rays, which can absorb most of the ultraviolet rays in the sun, so it can protect the creatures on earth from ultraviolet rays.
