In industrial and agricultural settings, productive dust is created as fine solid particles that remain suspended in the air for extended periods. During the production and use of cement, workers are frequently exposed to large amounts of cement dust. Without proper protection, this can have serious health consequences. Therefore, continuously improving working conditions, ensuring employee safety and health, and promoting safe and clean production are essential measures to complete production goals and reflect effective corporate management.
Dust can be categorized into several types. Inorganic dust includes metal dust (such as aluminum, iron, tin, lead, and manganese), non-metallic mineral dust (like quartz, asbestos, talc, and coal), and artificial inorganic dust (such as cement and glass fiber). Organic dust comes from plant and animal sources, while synthetic material dust, commonly found in plastic manufacturing, contains polymers along with additives like fillers, plasticizers, and stabilizers.
Exposure to different types of dust occurs in various work environments. In construction and industrial sites, workers often come into contact with silica dust, mixed dust containing quartz, limestone, clay, volcanic ash, shale, iron powder, coal, slag, gypsum, sand, and diatomite.
Dust poses a wide range of health risks. Soluble toxic dust can enter the respiratory system and cause poisoning, while radioactive dust may lead to radiation damage. Hard particles can irritate the eyes, causing corneal opacity or conjunctivitis. Dust can also block sebaceous glands, leading to skin conditions such as acne or pyoderma. Additionally, it can mix with earwax, forming cerumen.
The most severe impact of dust is on the respiratory system, causing upper respiratory tract inflammation, pneumonia, lung granulomas, lung cancer, and pneumoconiosis—such as silicosis or asbestosis. Pneumoconiosis, caused by long-term inhalation of dust, is the most common and dangerous occupational lung disease.
To prevent dust-related harm, several measures should be taken. First, process optimization and technological innovation can reduce dust generation at the source. Wet operations help control dust by preventing it from becoming airborne. Ventilation systems, including local exhaust and fresh air supply, can significantly lower dust concentration. Sealing dust sources and using filtration systems before releasing air into the environment are also effective strategies.
Personal protective equipment (PPE) is crucial. Workers should wear masks, such as gauze or filter masks, and those exposed to hazardous substances like benzene or high-manganese should use oxygen or air-breathing masks. After work, employees should shower and change clothes to avoid carrying dust home.
Regular monitoring of dust levels and medical check-ups are necessary to ensure worker safety. Those who develop health issues unsuitable for dusty environments should be reassigned promptly. Education and awareness campaigns are also important, reminding workers not to smoke or eat in hazardous areas and to maintain hygiene practices to prevent contamination.
