Harm of insulation materials – Glass wool. Glass wool, also known as glass fiber wool, is a material commonly used in the industrial sector, primarily for insulation, heat resistance, and moisture prevention purposes. However, long-term or improper exposure to glass wool may pose certain risks to human health. The following is a detailed analysis of the hazards associated with glass wool: Image of glass wool. 1. Eye damage · Cause: Glass wool contains a large amount of dust, and when this dust comes into contact with the eyes, it can damage the eye mucosa. · Symptoms: Prolonged exposure may cause eye diseases such as keratitis and conjunctivitis; in severe cases, corneal opacity and local abscesses can occur. · Protective measures: People who are exposed to glass wool over extended periods should take care to protect their eyes, avoiding direct contact with or staring at glass wool; safety goggles should be worn when necessary. II. Skin damage · Cause: Glass wool is an inorganic chemical material that contains various compounds, and it can be somewhat irritating to the skin. · Symptoms: Prolonged exposure may lead to dry and ulcerated skin, with those who have sensitive skin being more severely affected ； People who are prone to allergies may develop contact dermatitis, with symptoms such as skin redness, itching, and scaling. · Protective measures: Direct contact with glass wool should be minimized; if contact is necessary, protective gloves must be worn. III. Lung damage · Cause: Glass wool dust can enter the lungs through the respiratory tract and deposit there; such dust cannot be absorbed or broken down by the lungs, and its accumulation over time may lead to lung damage. · Symptoms: The main symptoms include coughing, expectoration, and shortness of breath; in severe cases, it may lead to occupational diseases such as pneumoconiosis and pulmonary fibrosis ； Furthermore, long-term exposure may increase the risk of lung cancer. · Protective measures: When in an environment with glass wool, a dust mask or face shield should be worn to prevent inhaling dust ； At the same time, regular occupational health checks are necessary to detect and treat lung diseases in a timely manner. IV. Other hazards · Allergic reactions: People who are prone to allergies may experience allergic symptoms such as local itching and rashes after coming into contact with glass wool. · Overall impact: Although glass wool itself is not highly toxic, long-term exposure can lead to various health problems, affecting the quality of life and working capacity. V. Recommendations for protective measures 1. Personal protection: Wear appropriate protective equipment such as goggles, dust masks, and protective gloves to minimize direct contact with glass wool and inhalation of dust. 2. Environmental control: Improve ventilation and dust removal facilities in the workplace to reduce the concentration of glass wool dust. 3. Health monitoring: Conduct regular occupational health checks to identify and address potential health issues promptly. 4. Training and education: Strengthen vocational health education and training for workers to raise their awareness of the hazards associated with glass wool and their knowledge of protective measures. 5. Operating procedures: When cutting and laying glass wool, operators must strictly follow the established operating procedures, avoiding forceful tearing or striking of the glass wool to reduce dust generation and suspension in the air ； After the work is completed, the work area must be cleaned promptly; wet cleaning methods should be used to remove any remaining dust, as dry sweeping can cause the dust to spread. The discarded glass wool should be sealed and disposed of in accordance with relevant regulations, to prevent secondary pollution from accidental disposal. 6. Emergency measures: If discomfort occurs after skin comes into contact with glass wool, avoid scratching the affected area; rinse it thoroughly with clean water as soon as possible and seek medical attention promptly ； If glass wool dust accidentally gets into the eyes, do not rub them; immediately rinse with plenty of flowing water and seek medical attention promptly ； If coughing and chest tightness occur after inhaling a large amount of dust, it is also necessary to seek medical attention at a hospital promptly.
