What is the harm of rock wool

summary

Rock wool is widely used in daily production and application. More and more friends begin to care about the harm of rock wool to the body. Let's introduce the harm of rock wool.

What is the harm of rock wool

Respiratory system harm: workers exposed to rock wool can appear X-ray chest film changes: namely pneumoconiosis changes.

Skin hazards: glass fiber workers often have contact dermatitis, but some workers can gradually tolerate it, which is called "hardening phenomenon". The degree of skin damage varies with the fiber diameter and surface roughness. It is generally accepted that the fiber diameter is more than 5 μ m, which has obvious irritation effect. A small number of workers exposed to glass fiber and rock wool developed skin allergy, but it has not been confirmed that these fibers are allergens.

Eye and mucous membrane hazards: workers exposed to glass fiber can suffer from conjunctivitis and keratitis, and corneal opacity and local abscess can be seen in severe cases. From the patient's eyes, the fibers with diameter less than 3 μ M can be washed out. Pathological examination of the patient's eyeball showed that corneal epithelial cells proliferated and the content of conjunctival mucin increased, indicating that it was mechanical stimulation. Animal experiments confirmed similar pathological changes. The results show that when the size and length of fibers are similar, the toxicity and carcinogenicity of asbestos substitutes are similar to asbestos. Rock wool dust has a certain biological damage to human and animals. Although its biological activity and pathological effect are not as good as asbestos, its harm can not be ignored when it is produced and used as a substitute for asbestos.

matters needing attention

We all have a relevant understanding of the hazards of rock wool. Rock wool is quite harmful to the body. We should try not to touch it in daily life. If it is the staff, we should pay attention to personal protection during construction!
