Project: Man-made vitreous fibres (MMVF)

Man-made vitreous fibres (MMVF) such as mineral wool are used for acoustic, thermal and electrical insulation and reinforcement in materials. MMVF are known to cause skin irritation. Is it still so?

Contamination of skin may arise through direct contact handling the materials, through indirect contact with contaminated surfaces, clothing and equipment, and by deposition of airborne fibres. A survey of skin effects among occupational and do-it-yourself insulators is performed. An interview study and provocation studies in a human whole-body exposure chamber have been performed. Skin effects and skin doses have been studied by different techniques in test subjects and in insulation workers. The results show that MMVF still cause skin complaints. This may be of importance for national and EU legislation such as classification, labelling and packaging (CLP).
