Handling and Storage Guidelines

Phosphoric Acid is a corrosive liquid. Laboratories must follow standard safety protocols:

  • Review the SDS before initial use and ensure it is accessible in your chemical hygiene plan
  • PPE Requirements: Chemical splash goggles, acid-resistant gloves (nitrile or neoprene), lab coat, and face shield when pouring or transferring
  • Storage: Keep drums in a cool, dry, well-ventilated area away from incompatible materials including strong bases, metals, and oxidizers
  • Containment: Store within secondary containment rated for the full drum volume; inspect bungs and closures regularly
  • Spill Response: Neutralize small spills with sodium bicarbonate or soda ash; follow your facility's spill response plan for larger releases
  • Regulatory Compliance: Handle in accordance with OSHA 29 CFR 1910.1450 (Laboratory Standard) and all applicable local and state regulations
