At work the platemaking units that used UV light sources had curtains to block exposure to the operator. It's also recommended to use yellow UV blocking glasses when working with such bright UV sources, see the dentists office when they UV cure that polymer filling. UV gun has an orange filter ring around it and the operator wears the glasses.
