In the world of welding and many other trade professions, there is a hidden danger that goes unnoticed - silica dust. Silica is a naturally occurring mineral found in some stones, rocks, sand, gravel, and clay. When these materials are worked, silica is released as fine dust known as respirable crystalline or silica dust. Silica dust is harmful when inhaled into your lungs as it is 100 times smaller than a grain of sand. Fabricators must know the potential hazards of silica dust and, more importantly, how to mitigate them for a safer workplace.
Inhalation of silica dust can lead to respiratory diseases such as silicosis, lung cancer, and other chronic pulmonary conditions. Occupations such as miners, construction workers, farmers, and engineers pose the most significant risk of exposure. Other occupations such as fabricators, sandblasters, paving, cement workers, bricklayers, demolition, stonemasonry, and welders are also at risk of exposure to silica dust.
To mitigate silica risk, workplaces should offer training associated with silica exposure and the importance of adhering to safety measures. The workplace should also be adequately ventilated to disperse airborne contaminants. This would be achieved through exhaust fans, open doors, or windows. Air assessments can help identify the areas that need to improve ventilation.
Person Protective Equipment (PPE) is paramount in minimizing silica dust exposure. Respirators offer a solution for preventing the inhalation of fine particles. Welders and other professionals should wear these respirators regularly, especially in enclosed spaces with poor ventilation.
Professionals must prioritize safety in the workplace to ensure they are not at risk for exposure to silica dust. Silica dust may be an invisible threat, but its ramifications are far-reaching. By understanding the risks and implementing mitigation strategies, a safer workplace can be achieved.
