Seek medical attention if a significant amount is swallowed, especially for concentrated solutions.

Note to Physicians:
Treat symptomatically.

HANDLING AND STORAGE

Handling:
Use appropriate PPE including chemical-resistant gloves and goggles, especially for concentrated E270 Lactic Acid.
Avoid breathing mists and avoid contact with skin and eyes.
Add acid to water slowly during dilution to control heat release and splashing.

Ventilation:
Use local exhaust or general ventilation to control mist levels.
Avoid aerosol formation in enclosed spaces without adequate airflow.

Storage:
Store in tightly closed, compatible containers in a cool, well-ventilated area.
Keep away from strong bases, strong oxidizers, and reactive metals.

Spill and Leak Procedures:
Ventilate the area and use appropriate PPE for spill response.
Contain spill with inert absorbent and neutralize carefully with suitable neutralizing agent if trained and permitted.
Dispose of waste according to local regulations and facility procedures.

Handling Precautions:
Control concentration and dosing because E270 Lactic Acid significantly affects pH, microbial stability strategy, and flavor profile.
Verify product pH and titratable acidity during formulation to ensure safety and desired sensory outcome.
Rotate stock using FIFO practices and inspect containers for compatibility and integrity.
