Some people experience temporary discomfort (or itching) when handling mineral wool. This itching is a mechanical reaction to the coarse fibres and generally abates shortly after exposure has ceased. Irritation of the upper respiratory tract or the eyes, similar to that caused by accidental ingress of many other forms of dust or foreign bodies, may also be experienced by some. Effects of these mechanical irritants are totally different to that of “chemical” irritants.
Those who experience discomfort with existing skin problems, should wear gloves or other suitable protection. Loose fitting clothing should be worn, avoiding constrictions at wrist and neck. If working with products above head height, eye protection goggles should be worn.
Mineral wool insulation has been extensively studied and not proven to have any adverse effects on respiratory health. Its unique composition and fiber structure make it an inert material that does not inhibit mold growth that can release any harmful particles into the air. If mineral wool fibers get inhaled, the body takes care of them in the way it takes care of household dust. It breaks them down easily and gets rid of them without us even noticing. As a safe and reliable choice, mineral wool insulation offers peace of mind, ensuring a healthy indoor environment without compromising on thermal performance or fire safety.
Mineral wool insulation does not use raw materials nor contain substances that are carcinogenic, mutagenic or toxic to reproduction (CMR substances) or ‘Very High Concern’ or ozone-depleting substances. It has been reviewed and verified by the World Health Organisation (WHO), International Labour Organisation (ILO), International Agency for Research on Cancer (IARC) and International Programme on Chemical Safety (IPCS) to be safe for humans and does not pose any health risks.
In October 2001 a panel of international scientific experts reviewed the earlier 1987 IARC Monograph and classification in the light of more recent scientific evidence and understanding of the health effects of various man-made mineral fibres. They concluded that the classification of glass mineral wool fibres should be reduced from Group 2B (possibly carcinogenic) to Group 3 (not classifiable as to its carcinogenicity to humans), thus updating IARC’s earlier precautionary classification, which arose as a consequence of insufficient evidence being available at the time of issue.
