Results and discussion

Results of examinations:

Case report of an incidence of sensitisation to ferric chloride and ferric sulphate. A 44 year old male presented with eczema-type reactions on his skin in areas that were exposed to steel particles during his job using high pressure cleaning equipment to remove steel particles from construction elements. An initial patch test using steel particles resulted in erythema after 48 hours. The reaction had increased at 72 hours. Further tests were carried out. The substances tested and the results are tabulated below. These tests were repeated three times with identical results. About 30 people were used for the control test.

Substance 48 hours 72 hours
zinc sulphate 5% - -
ammonium molybdate 1% - -
calcium chromate 0.5% - -
calcium dichromate 0.5% - -
chromium sulphate 2% - -

aluminium vanadate 1% - -
cobalt chloride 2% - -
nickel sulphate 5% - -
copper sulphate 5% - -

ferrous sulphate 10% - -
ferric chloride 0.1% - -
ferric chloride 1% - +
ferric chloride 2% - +++
ferric sulphate 10% - ++

The authors concluded that very close contact with the metal had resulted in sensitisation to ferric compounds in this individual.
