Fume Fixes: Your Guide to Cleaner Air Solutions!

Welding is an essential process in many industries, but like many other things, it is not without risks. It's is important for both welders and their employers to properly mitigate them. Today, the risk we’re specifically talking about is the fumes generated during the welding process. Welding fumes are a complex mixture of airborne particles and gases created when metals are heated above their boiling point. This results in vaporization that then condenses into fine particles and can contain a variety of hazardous substances- including manganese, hexavalent chromium, nickel, and zinc!

The Occupational Safety and Health Administration (OSHA) has established strict regulations regarding permissible exposure limits (PELs) for various welding fumes, as well as a hierarchy of controls that can be used to protect workers. Staying compliant with these regulations requires more than just awareness—it demands action. So today we're talking about engineering controls that welders and their employers can make use of to stay safe. 

OSHA Hierarchy for Weld Fume Control

Elimination/Substitution: Whenever possible, substitute hazardous materials with safer alternatives.
​
Engineering Controls: Use ventilation systems, fume extractors, and other technologies to capture and filter harmful fumes at the source.

Vertical Divider

Administrative Controls: Implement work practices that reduce exposure, such as rotating tasks among workers or limiting the time spent on tasks that generate fumes.
​
Personal Protective Equipment: Use appropriate PPE, such as respirators, when other controls are inadequate. 

Fume extractors are a critical component of engineering controls. They work by capturing welding fumes at the source, filtering out harmful particles, and returning clean air to the workspace. By effectively reducing airborne contaminants, fume extractors help to protect workers from the health risks associated with welding.
