Handling and Storage Guidelines

Phosphoric acid is a corrosive material that requires proper handling procedures in any pharmaceutical setting. Your facility's EHS protocols should include the following baseline requirements:

  • Review the SDS before initial use and ensure it is accessible to all personnel who handle the product
  • Personal Protective Equipment (PPE): Wear chemical-resistant gloves, splash-proof safety goggles, and a chemical-resistant apron at minimum. A face shield is recommended during transfer operations
  • Storage: Store drums in a cool, dry, well-ventilated area on secondary containment. Keep away from strong bases, metals, and incompatible materials
  • Container Integrity: Keep drum bungs tightly sealed when not in use to prevent contamination and moisture absorption
  • Spill Response: Maintain spill kits rated for corrosive liquids in all storage and handling areas
  • Regulatory Compliance: Follow all applicable OSHA, EPA, and state-level regulations for corrosive chemical storage and handling in pharmaceutical facilities
