Plasma Cutting & Hexavalent Chromium

Dec 19, 2018

Plasma cutting has become common in the industry today. It is ideal for applications requiring precision cuts. What many people do not understand are the dangers that can rise from a plasma table. An electric arc is sent through a restricted opening, heating the gas to an extreme temperature. This energy breaks apart gas molecules and creates plasma. When loose electrons collide they release enough energy to cut through the metal. Many metals are covered by a surface layer of anti-corrosive chromium. This chromium keeps stainless steel strong and makes it more resistant to corrosion. It is not dangerous to humans. However, hot work such as plasma cutting changes the nature of the chromium. When that much heat is applied to chromium, it oxidizes and converts the chromium to a hexavalent state. Hexavalent chromium, or Cr VI, can be extremely dangerous.

This infographic looks at the hidden dangers of plasma cutting and laser cutting. One of the biggest dangers associated with these is hexavalent chromium when cutting stainless steel. It can pose many health risks and proper precautions should be taken to avoid the risks associated with it. The CMAXX Laser can create a safer work environment by removing this and other dangerous substances from the air.
