Hexavalent Chromium

Diversitech - Air pollution control for hexavalent chromium fumes from welding stainless steel and galvanized metals

What is Hexavalent Chromium?

Hexavalent chromium is a chemical compound that is used in the manufacturing process for stainless steel. Welding, grinding and sanding materials that are coated with chromium can create hexavalent chromium fumes. Some of these materials include stainless steel, carbon steel with high carbon content and galvanized steel. Hexavalent chromium fumes must be filtered at the source, before they can be inhaled by workers.

Serious Health Effects

Hexavalent chromium fumes, also known as “hex chrome” fumes, have the potential to cause a range of serious respiratory tract problems. The fumes and dust are carcinogenic, and repeated exposure can produce health effects that include:

  • Occupational asthma
  • Allergic contact dermatitis
  • Skin ulcers
  • Eye irritation and damage
  • Kidney damage
  • Liver damage
  • Pulmonary congestion
  • Abdominal pain
  • Lung cancer

Are You at Risk?

If your work environment includes hexavalent chromium as a by-product of welding, grinding or sanding applications, it’s important to find a filtration solution that will remove the fumes at the source, before workers are exposed. Factors such as the length of exposure, the type of material being used and level of protection all play significant roles in how much of a risk your workplace happens to be.

OSHA Guidelines

In 2006, OSHA dramatically overhauled regulations dealing with Hexavalent Chromium exposure hazards.  In summary, the changes are:

  • Reduction in the personal exposure limit (PEL) from 52 micrograms to 5 micrograms per cubic meter of air on an 8 hour time-weighted average
  • Provisions for preferred methods for controlling exposure:  Capture-at-Source
  • Provisions for protective work clothing, equipment, hygiene, respiratory protection, medical surveillance, hazard communication, and record keeping
