A recent study by the city of Houston’s Bureau of Pollution Control and Prevention, as reported by Ingrid Lobet of the Houston Chronicle, indicates that using a torch to cut up metal may release dangerous levels of hexavalent chromium into the air.
As you know, the EPA says hex chrome is a human carcinogen that targets the respiratory system.
We’ve blogged about hex chrome in the past. [See links below.] And Sentry Air has tested the effectiveness of its filtration devices on hexavalent chromium in welding fumes.
When you review the test results linked above, you’ll see that “there was a 99.3% reduction in the concentration of hex chrome in the ambient air near the welder” and “the potential exposure of the welder was reduced by more than 97% by the Sentry Air Systems welding fume extractor.”
We like recycling
Sentry Air supports recycling efforts. We like its objectives and we like the benefits it can produce for companies and consumers.
We don’t want recycling to sicken anyone.
Field experience meets OSHA standards
For more than 20 years, we’ve provided portable fume extractors to welders in many industries.
Edker Industries, Inc., a precision sheet metal fabrication and laser cutting company, called our Model 400 Welding Fume Extractor “top notch safety equipment” because an OSHA air sampling device found no trace of hex chrome when their employee was welding stainless steel.
