News24xx.com - A technician who works with welding equipment is often advised to wear face protection. The reason is because welding is a job with a risk to your health. A recent study published in the journal Occupational & Environmental Medicine found the evidence that smoke from welding can increase the risk of getting lung cancer.
Dr. Denitza Blagev from Intermountain Medical Center found out after analyzing data from 45 other studies with around 17 million participants. Overall, people who work as welders or are often exposed to welding smoke are 43 percent more likely to develop lung cancer. "And with this number, smoke from welding can be classified as 'carcinogenic' to humans" the researchers wrote as quoted by Reuters on Wednesday, May 22nd 2019.
Smoke from welding itself is produced when the metal is heated above its melting point and then evaporates and condenses into fine particles in the air. The exact mixture of chemicals in the air can depend on the type of metal used, the welding process, and where the work is done.
For example nickel and chromium compounds are known to cause lung cancer and both are easily found in smoke from welding stainless steel.
