While continuously striving to improve the safety of toys and, at the same time, seeking to cut "red tape" where possible the European Commission has decided to exempt nickel in electric toys from the limit value regarding carcinogenicity (Toy Safety Directive 2009/48/EC, Annex II, section 3, No 5).
However the nickel limit values to protect children against sensitisation and ingestion toxicity remain unchanged. The above exemption is possible without compromising safety since nickel is only carcinogenic when present in the form of inhalable fumes. The Scientific Committee on Health and Environmental Risks (SCHER) considered, in its opinion of 25 September 2012, that nickel metal fumes are not expected to be released from toys, not even from badly functioning electric motors such as in model cars or railroad locomotives.
