OSHA's Hexavalent Chromium Standard
Hexavalent chromium [Cr(VI)] may be present in fumes that are created in the welding and cutting processes of stainless steel, non-ferrous chromium alloys and chrome plated metals. The Occupational Safety and Health Administration's (OSHA) Hexavalent Chromium Cr(VI) Standard sets the permissible exposure limit for Cr(VI) as 5μg/m3 (micrograms per cubic meter) as an eight-hour time-weighted average (TWA).

Make sure to use respiratory protection when needed. Refer to the filler metal SOS sheets for information about the respiratory and contact dangers of hexavalent chromium.

Welding Fumes and Gases
Welding and cutting processes generate fumes that can be hazardous if inhaled. Welding fumes are comprised of:
  • Vaporized metal from the base metal itself, from welding rods, wires, coatings and fluxes
  • Rust, mill scale and coatings that may be on the surface of the metal
  • By-product gases such as ozone, carbon monoxide and nitrogen dioxide It is important that workers be protected from over-exposure to these fumes and gases.
National Institute for Occupational Safety and Health (NIOSH) studies suggest that welders have an increased risk of respiratory illness,
including bronchitis, airway irritation, lung function changes and lung cancer*

Help protect yourself with safety equipment designed specifically for the professional welder. Welders must have proper ventilation and an
approved respirator to protect them from hazardous fumes and gases. Respirators should be comfortable and not hamper the use of other
face-shielding equipment.

There are situations when standard air-purifying respirators alone will not guarantee an adequate supply of breathable air. Welding operations
in areas with poor ventilation and air quality increase the risk of inhaling toxic fumes. Therefore, it may be necessary to provide additional
ventilation or an air-supplied respirator. Exhaust hoods or fume extractors, combined with the use of exhaust fans, are common means
of removing fumes.
