During flux-cored arc welding (FCAW) indoors, a welder notices a significant amount of visible fumes accumulating in their work area despite the shop's general ventilation system. What immediate action should the welder take to ensure their safety?

Question: During flux-cored arc welding (FCAW) indoors, a welder notices a significant amount of visible fumes accumulating in their work area despite the shop's general ventilation system. What immediate action should the welder take to ensure their safety?

Answer options:

• Increase the wire feed speed to complete the weld faster. ✅ Request the installation of local exhaust ventilation (LEV) at the source.
• Continue welding, assuming the general ventilation will eventually clear the fumes.
• Take frequent breaks outside the work area to clear their lungs.

Correct answer: Request the installation of local exhaust ventilation (LEV) at the source.

Explanation: Accumulation of visible fumes indicates that general ventilation is insufficient, and local exhaust ventilation (LEV) is necessary to capture fumes at their source before they spread. Increasing wire feed speed or taking breaks does not address the root cause of the exposure, and continuing to weld puts the welder at risk.
