When two metals are welded together, a harmful emission of manganese, carbon monoxide, and other substances occurs. Manganese is a toxic substance and has been shown to cause serious injury in a short amount of time. Welding rod fumes have been linked to severe and irreversible brain damage including paralysis, the disease Parkinsonism, and manganese poisoning called Manganism in exposed workers. Welding rod manufacturers and companies who failed to take safety measures to protect welding rod workers may be held financially responsible for these injuries.
