How can employers reduce hexavalent chromium exposure?

The most effective way to reduce hexavalent chromium exposure is through source capture and weld fume control systems designed to keep fumes out of the breathing zone.

Common control methods include:

• Fume extraction arms
• Fume extraction guns/torches
• Backdraft plenums
• Welding tables with integrated extraction
• Industrial ventilation systems
• Ambient air filtration as secondary control

Routine air sampling and exposure testing are also important to confirm compliance with OSHA limits.
