Metals in Air

During manufacturing and processing, metals can aerosolize or produce fumes that contain harmful amounts
of hexavalent chromium, tin, titanium dioxide or lead. Exposure to these metals can cause breathing difficulty,
eye irritation, damage to internal organs, central nervous system impairment, immune system suppression and
other deleterious health effects.

Health and safety professionals in these facilities are challenged to develop safety protocols to ensure their
workers operate in a safe working environment. One protocol requires air to be sampled for metal fumes by a
qualified Industrial Hygienist, which ensures that monitoring is done properly. Samples must also be collected
according to the Permissible Exposure Limits for common metal fumes found in industrial environments. These
exposure limits are published by ACGIH in conjunction with OSHA & NIOSH.

Bureau Veritas analyzes air samples for metal fumes using more than 90% of the published NIOSH and OSHA
methodologies. Our accredited laboratory uses high-tech equipment including ICP/MS and ICP-OES that can
detect as low as 0.5 ng of certain metals, allowing us to provide results with the highest level of accuracy and
precision. We also use CVAA technology to detect ultratrace levels of mercury.

Bureau Veritas regularly participates in the Industrial Hygiene Proficiency Analytical Testing (IHPAT) program for metals analysis, ensuring that our test methods are not only accurate but repeatable for clients.
