Fibre optic technology is increasingly being used in Switzerland - whether for fast Internet access or as a Insulation material in the building industry. The question repeatedly arises as to whether glass fibres pose a similar health risk to asbestos. This article explains the Differences, risks and the current state of science.

Differences between glass fibres and asbestos

Asbestos is a naturally occurring, fibrous mineral that was once widely used due to its heat resistance and strength.

Glass fibres, on the other hand, are artificially produced fibres made from molten glass, which are spun into fine fibres. They are often used as insulating materials (mineral wool) or for telecommunication cables.

Health risks of glass fibres

New research results show: Glass fibres are significantly less dangerous than asbestos fibres. Asbestos is now banned in Switzerland, as inhaled fibres can cause serious illnesses such as asbestosis, lung cancer or mesothelioma.

While asbestos fibres are extremely durable and bio-resistant, glass fibres are broken down or excreted more quickly in the human body, which reduces the risk of chronic lung diseases.

However, contact with glass wool can lead to skin irritation or irritation of the respiratory tract, especially when processed without suitable protection. It is therefore important to handle glass fibres correctly, especially on construction sites.

Regulations and protective measures in Switzerland

In Switzerland, clear occupational health and safety guidelines apply to the handling of mineral fibres. Manufacturers must state whether their products are considered "biodegradable", i.e. can be broken down in the body. Materials that do not fulfil these requirements are subject to stricter protective measures.

The Federal Office of Public Health (FOPH) and Suva recommend suitable protective equipment such as gloves, respiratory protection and protective clothing when handling glass fibres.

Conclusion: glass fibres are not comparable to asbestos

Glass fibres are not harmless, but they are not the same as asbestos fibres either. While inhaling even the smallest quantities of asbestos can have fatal consequences, the risks associated with glass fibres are mainly mechanical and can be controlled if handled properly.

Compliance with protective regulations provides effective protection against health risks. The population in Switzerland can be reassured: When used correctly, fibre optic technology does not pose any comparable health risks to asbestos - neither in the network connection nor in construction.
