Amine Flux Sensitization Dermatitis in Electricity Cable Jointers

SUMMARY.— Economic pressures have brought about a change in the conductors of electrical power cables; aluminium is now widely used in place of copper. The development of a jointing flux containing aminoethylethanolamine made this possible, and this has been very extensively used by the Electricity Supply Industry in this country. This amine has given rise to a high incidence of dermatitis amongst cable jointers, and is here shown to be a powerful sensitizer. Surveys have shown an incidence of dermatitis of 10% to more than 30%, in all grades of severity. A satisfactory alternative flux has been developed and is now in field use. This investigation underlines many principles of economic as well as medical importance.
