What are the hazards of rock wool board to the human body?

As an alternative to asbestos, the damage of rock wool to the human body is as follows:

First, the respiratory system hazard: the discipline of pneumoconiosis changes in workers who have been exposed to glass wool, rock wool and mineral wool for a long time has greatly increased. Among these people, the lung function test FVC (forced expiratory volume) was lower than normal, but it was far less severe than asbestos workers. The pathological examination of the lungs of workers exposed to long-term exposure to glass wool showed that there were glass fiber cell foci in the lung tissue, the mild hyperplasia of the collagen, and the probability of lung cancer and lung abscess was also higher than that of the average person.

Second, the skin hazard: the incidence of contact dermatitis in rock wool, glass wool workers is very high, but with the length of time, workers will have tolerance and skin hardening phenomenon. The degree of damage to the skin by these insulation materials is related to the fiber diameter and surface roughness. Studies have shown that only when the fiber diameter exceeds 5 μm, it will have a significant stimulating effect on the skin.

Third, eye and mucous membrane hazards: workers with long-term exposure to fiberglass are prone to conjunctivitis and keratitis. In severe cases, corneal opacity and local abscess may occur, and fibers with a diameter of 3 μm or less can often be washed out in the patient's eye. Pathological examination of the patient's eyeballs reveals that corneal epithelial cell hyperplasia and increased mucosal mucin content are the result of mechanical stimulation.

Therefore, we must pay special attention to the damage of rock wool board.
