Safety & Health

Health & Safety Information
  • Under current U.S. OSHA's Hazardous Communication program DAA is classified as a combustible liquid and can cause serious eye and respiratory irritation. Keep the material away from heat sources, hot surfaces, open flames, and sparks.
  • Observe good industrial hygiene practices and use appropriate Personal Protective Equipment.

Storage & Handling

Storage & Handling
  • General industry practice is to store DAA in carbon steel vessels, however stainless steel is preferred.
  • DAA should be stored only in tightly closed, properly vented containers away from heat, sparks, open flame or strong oxidizing agents.
  • Handle empty containers carefully. Combustible residue remains after emptying.
  • Provided proper storage and handling precautions are taken, DAA manufactured and delivered by Monument Chemical is stable for at least 12 months from the date of manufacture. DAA that is subsequently repackaged, handled and/or delivered by third parties may have a different shelf life and may require third party shelf life studies. Color may increase overtime depending on storage conditions. Product past the retest date should be evaluated to confirm that all specifications are within their limits before use.
