Any time metals are welded together, toxic fumes, gases, and particles are released into the air.
The particles in welding fume are typically smaller than 0.1 µm.
To understand how small this is, consider a strand of hair. An average strand of hair is 99 µm meaning that the particles in weld fume are so tiny they're completely unseen to the naked eye!
Due to their small sizes, the particles in welding fume get easily trapped in the respiratory system targeting the bloodstream, central nervous system, and kidneys. Without a way to control and capture these pollutants, welders and surrounding areas are exposed to several health and safety risks.
Prolonged exposure to weld fumes can result in various types of cancer including lung, larynx and urinary tract.
Although fresh air may be supplied to your environment by general ventilation, relying solely on ventilation for weld fume control is ineffective.
To ensure the safety of machine operators, it's critical to implement welding fume extraction systems in work environments where welding equipment is being operated. Fume extraction systems must be properly used and positioned based on the specific machining process and application taking place to guarantee effectiveness.
