Does anyone have any experience of risk-assessing ultra-violet lights used for enhancing faded script, or of establishing safety guidelines for their use? We have received some advice over the telephone from the Heath and Safety Executive and from the Non-Ionising Radiation Protection Board (as suggested by the HSE). However, further help would be appreciated. We have no handbook or documentation for the light we use here (a 'Luxo' brand).
