Keep HEDP in a tightly closed container. Protect from physical damage. Store in a cool, dry, ventilated area away from sources of heat, moisture and incompatibilities. Do not ingest or inhale and avoid contact. Containers of 1-Hydroxyethylidene-1,1-Diphosphonic Acid or HEDP may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.

Exposure Limits: No occupational exposure limits established.
Ventilation: Provide local exhaust ventilation system. Ventilation equipment should be explosion-resistant if explosive concentrations of material are present. Ensure compliance with applicable exposure limits.
Eye Protection: Wear splash resistant safety goggles. Provide an emergency eye wash fountain and quick drench shower in the immediate work area.
Clothing: Wear appropriate chemical resistant clothing.
Protective Material Type: Rubber
Respirator: Under conditions of frequent use or heavy exposure, respiratory protection may be needed. Use any dust, mist and fume respirator. Any air-purifying respirator with a high-efficiency particulate filter. Any powered, air-purifying respirator with a dust, mist and fume filter. Any powered, air-purifying respirator with a high-efficiency particulate filter.
