Environmental risk analysis of ultraviolet phototherapy centres in Ireland

Abstract

Ultraviolet (UV) radiation is commonly used in the treatment of dermatological conditions such as psoriasis. It is known that high levels of exposure to UV radiation (UVR) will increase the risk of adverse biological effects. Exposure limit values for UVR have been developed by the International Commission on Non-Ionising Radiation Protection (ICNIRP) and occupational exposure to phototherapy staff should be kept within these limits. The use of environmental controls such as warning signs, good ventilation and UV-opaque curtains will significantly reduce the risks to staff, patients and members of the public. The aim of the study is to identify hazards in phototherapy centres and present recommendations for reducing risks. An environmental risk assessment has been carried out at eleven phototherapy centres in the Republic of Ireland. The study assessed a number of areas such as patient safety, staff safety, room design and UV leakage measurements. The majority of clinics are well designed and there is consistent use of protective equipment. The results show that on the whole there is a satisfactory level of risk management in phototherapy centres. Recommendations on maintaining good safety standards are presented.
