Handling and Storage Guidelines

Phosphoric acid is a corrosive liquid that demands respect in any manufacturing environment. Follow these protocols:

  • Review the SDS thoroughly before first use and ensure it is accessible at the point of handling
  • Wear appropriate PPE: Chemical-resistant gloves, splash goggles or face shield, and acid-resistant apron at a minimum
  • Store drums upright in a cool, dry, well-ventilated area away from incompatible materials (strong bases, most metals, oxidizers)
  • Keep containers sealed when not actively dispensing to prevent moisture absorption and concentration changes
  • Use compatible equipment: Stainless steel (316 grade), HDPE, PTFE, and polypropylene are generally suitable for transfer and storage
  • Contain spills promptly using appropriate neutralizing agents and follow your facility's spill response plan
  • Comply with all applicable OSHA, EPA, and DOT regulations for handling, storage, and transportation of corrosive materials
