An unusual cause of sunbed burns

Three women successively using the same sunbed received superficial to medium partial thickness burns as a result of an ultraviolet filter slipping out of place. Whilst the longer-term effects of the various spectra of ultraviolet (UV) light continue to be evaluated, the near-immediate cutaneous and/or ocular sequelae of excess exposure are well known. Cutaneous burns are not, however, immediately manifest and it is concluded that suntanning devices should incorporate failsafe mechanisms activated by filter slippage or other malfunction.
