Weld Smoke: Know the Health Risks
Weld Smoke and Fume Dangers
Weld smoke is a direct cause of Pneumosiderosis, also known as welder’s lung. Inhaling iron dust or fumes, usually from welding, is a serious health issue. While it’s one of the most common occupational lung diseases of welders, it’s not the only one. Welders are also at risk of chronic bronchitis and cancer. Fortunately, a properly designed dust and fume collector, like our CMAXX™, can prevent these problems.
A case study from the publication Cases Journal gives an example of how welder’s lung can occur. It follows the case of a 64-year-old man who went to his doctor with a cough. He had worked as a welder in an automobile factory for 15 years, welding steel frames. The work area was small and enclosed, without a proper dust collection system to remove weld smoke and fumes.
The man’s doctor found that his lung X-ray was abnormal. Tests showed that his lungs contained many white blood cells full of iron. White blood cells remove things from your lungs that don’t belong there, but large amounts of inhaled iron are too much for them to handle. This buildup of iron causes coughing, shortness of breath, and eventually chronic lung disease.
They advised the man to stop working as a welder. His doctor treated him for his symptoms, and after some time his lung function returned to normal. However, he remains at an increased risk of lung cancer as a result of his long exposure to hexavalent chromium present in the steel.
Along with welder’s lung, inhaled welding dust or fumes also causes an increased risk of cancer. Hexavalent chromium, found in the steel the man in the case study worked on, is a known carcinogen. Welding, in general, increases cancer risk.
How Do You Prevent These Risks?
Because the fumes and smoke from welding contain iron and other metals in very, very small particles, inhalation deep into the lungs is easy. Because these particles are so small, our DeltaMAXX™ nanofiber filters are efficient at removing dust as small as .3 microns, making them an excellent choice for welding and other metalworking applications.
While pneumosiderosis most often affects welders because they are usually very close to the materials they’re working with, the same problem can affect people who are exposed to fumes from laser or plasma cutting. Dust from these applications also may contain hexavalent chromium and other health hazards. Our CMAXX™ system for cutting tables can remove fumes from the air before employees are exposed to them.
The most basic way to prevent welder’s lung is to remove weld smoke and fumes from the air that welders are breathing. A dust and fume collection system like the CMAXX™ can be designed to capture fumes from individual welding stations or from the ambient air. Our systems work with you to keep welders safe and healthy. Learn more about welding fumes and cancer.
