Safety Information

Signal Word: Not classified as hazardous under GHS

GHS Classification: This substance is not classified as hazardous according to the Globally Harmonized System (GHS).

Handling and Storage

• Handling: Avoid generation of dust. Use standard laboratory PPE (gloves, goggles, lab coat)

• Storage: Store in tightly closed containers in a dry, cool, and well-ventilated area. Protect from moisture and incompatible substances (e.g., strong oxidizers)

Environmental Considerations

Glycine is considered low in environmental toxicity, biodegradable, and generally safe under standard disposal conditions. Large quantities should not be released into wastewater without proper treatment.
