This paper summarises a short presentation delivered at the conference ‘Volatile Binding Media in Heritage Conservation’. The author, a health and safety advisor, was asked to comment on the safety of cyclododecane (CDD) to human health, given recent debate about this issue. This paper discusses the possible routes of exposure to CDD for conservators, and looks at these in the light of known safety data. The author concludes that CDD is not hazardous to use.
