Protection Methods Against Molten Metals
Molten metals are used in various fields, from industrial production to artisanal craftsmanship. However, processing and utilizing these metals come with inherent risks. It is important to pay attention to safety measures when working with molten metals, as accidental contact or exposure can lead to serious consequences. Here are some fundamental methods for protecting against molten metals:
Personal Protective Equipment (PPE): When working with molten metals, it is important for workers to use appropriate personal protective equipment. Among these equipment are thermal gloves, face masks, thermal clothing, and suitable footwear. These gears prevent skin contact with molten metals and ensure the safety of workers.
While the risk of large molten metal splashes is accidental, wearing protective clothing is essential. The most important aspect is selecting the correct fabric type for protective garment production. The fabric should be able to repel molten aluminum splashes, prevent them from adhering to the garment, minimize heat transfer, and prevent burns.
Because aluminum has a melting temperature of 780°C, significantly lower than steel's 1,400°C melting temperature, aluminum splashes cool and adhere to clothing more easily. Therefore, even products to be used in the iron-steel industry should prefer fabrics with the highest resistance to aluminum molten metal (D3) when looking for the highest resistance to molten metal splashes.
Most molten metal resistant fabrics on the market use a fiber combination that does not respond well to molten aluminum splashes (finished cotton, polyester, Para-Aramids, blended modacrylics). FR viscose and wool (unprocessed) fibers have the best slip properties for molten aluminum.
The Marlan Plus series fabrics achieve excellent protection values in very light fabric weights, making them highly light flame-retardant fabrics for foundries.
In accordance with the European EN ISO 9185 standard and the American ASTM F955-07, Marlan Plus fabric achieves the highest rating for aluminum splashes, D3. It also ranks at the highest level, E3, for iron and steel splashes. This fabric also provides protection against other molten materials such as cryolite, copper, nickel, zinc, lead, magnesium, and other ferrous metals.
The primary advantage of Marlan Plus over other fabrics for foundries is its ability to provide more protection in lighter weights. A weight of 310 g/m² provides D3 + E3 against molten metal splashes and results in 8.3 Cal/cm² for electric arc protection.
The comfort level of Marlan Plus fabric is enhanced by the use of TENCEL® fiber, a new fiber in its composition. This fabric has a pleasant touch, high breathability, and is extremely comfortable. Additionally, the blend of wool and flame-retardant fibers provides good insulation and prevents molten metal from adhering to the fabric, a common issue with synthetic fiber fabrics.
Ventilation Systems: Adequate ventilation systems are important in areas where molten metals are processed. These systems remove harmful vapors and fumes from the workplace, protecting workers' respiratory health. Additionally, they regulate the temperature and humidity levels in the workplace, making the working environment more comfortable.
Training and Awareness: Providing workers with education and awareness about working with molten metals is important. This training provides information about the potential hazards of molten metals and guides workers on following proper safety protocols.
Fire Prevention: Workplaces where molten metals are present carry a significant risk of fire. Therefore, having firefighting equipment and establishing fire prevention procedures are necessary. Additionally, workers should be trained on how to respond in the event of a fire.
Workspace Organization: Maintaining a clean and organized workspace where molten metals are handled increases worker safety. Additionally, proper storage of hazardous materials and good lighting in the workspace are important.
Safety when working with molten metals is a shared responsibility between workers and employers. The protection methods mentioned above are a fundamental step toward creating a safe working environment. However, since every workplace is different, it is important to conduct a site-specific safety assessment to identify risks and implement appropriate measures. Remember, safe working environments are the key to a healthy and productive workforce.
