Handling and Storage
-
Handling: Avoid breathing vapors or direct contact. Use in fume hood with appropriate PPE (goggles, gloves, protective clothing).
-
Storage: Store tightly closed in a cool, well-ventilated area away from light, heat, acids, and oxidizers. Avoid freezing.
Environmental Considerations
Glutaraldehyde is highly toxic to aquatic organisms. Prevent any uncontrolled release into soil or water systems. Waste should be neutralized and disposed of in accordance with local hazardous waste guidelines.
