As the representative of the A1-class non-combustible insulation material, rock wool is generally used for the exterior wall and roofing insulation in houses and industrial pipeline insulation. However, many users are concerned: "Is rock wool harmful to health?" The answer is that, if used properly, the health risk caused by rock wool is very low. It is mainly made up of short-term mechanical irritation without chemical poisoning. According to the evaluation by internationally authoritative organizations, rock wool fibers are safe and reliable.

First, regarding the risk of cancer: After assessment in 2002, IARC, the International Agency for Research on Cancer, which is a branch of the World Health Organization, classified rock wool as an asbestos substitute to Group 3: not classified as a human carcinogen. In other words, evidence so far is inadequate to prove its carcinogenicity. That puts it into the same category as caffeine. The EU REACH regulation also confirms that the rock wool fibers Note Q standard has a high biodegradability of >95% and will not be retained in the lungs for a long period. The US National Toxicology Program has also withdrawn its carcinogenic warning.

 

Common short-term risks are primarily physical irritants:

1.Skin exposure: Fibers that penetrate the skin will produce itching and redness, much like mosquito bites;

2.Inhalation of small amounts of fibre: Dry, itchy throat, mild cough, usually heals on its own within 1-2 days;

3.Eye contact: Brief stinging which disappears following rinsing.

 

These irritations are not toxic but rather a result of the physical properties of the fibers. Several epidemiological studies have shown that workers exposed for a long period to modern rock wool do not have any increased risk of either lung cancer or fibrosis.

 

Safety precautions are super simple:

- Wearing an N95 mask and protective clothes, gloves, and goggles during construction;

- Making sure to ventilate and clean your body after installation.

- Choose low-dust packaging products.
