Precautionary statements

Although sodium azide is only < 0.1 % w/v of the product, the Precautions and Warning section of the product insert states: • Harmful if swallowed. • The calibrators / controls contain sodium azide preservative, which may react with lead or copper plumbing to form potentially explosive metal azide. When disposing such liquids always flush with a large volume of water to prevent azide build-up. See Sodium Azide in the National Institute for Occupational Safety (NIOSH). Pocket Guide to Chemical Hazards. Third Printing, September 2007. (https://www.cdc.gov/niosh/npg/default.html) • The calibrators / controls are prepared from non-sterile human urine. They are not tested by licensed reagents for the presence of antibodies to human immunodeficiency viruses, the hepatitis antigens, and/or anti-hepatitis antibodies. They should be handled as potentially infectious. Always apply good laboratory practice to avoid any skin contact or ingestion. • Do not use the calibrators / controls beyond their expiration dates.
