Inhalation: Move affected person to fresh air, seek medical attention if symptoms persist
Eye Contact: Immediately rinse opened eye under running water for several minutes, see physician if irritation develops
Skin Contact: Remove contaminated clothing, wash skin with soap and water, medical help if irritation occurs
Ingestion: Rinse mouth with water, never give anything by mouth to an unconscious person, contact medical professional if unease appears
Suitable Extinguishing Media: Use water spray, foam, dry powder, or carbon dioxide
Specific Hazards: Combustion may produce CO, CO2, and nitrogen oxides
Protective Equipment: Firefighters wear full protective clothing and self-contained breathing apparatus
Explosion Risk: Fine dust dispersed in air may ignite at high concentrations, minimize dust accumulation away from ignition sources
Personal Precautions: Prevent contact with eyes, skin, and clothing, avoid breathing dust, ventilate area
Environmental Precautions: Prevent entry into waterways, drains, or soil
Cleanup Methods: Use vacuum or wet sweeping to collect material, transfer to proper waste container, avoid raising dust, flush area with water
Handling: Operate in well-ventilated space, minimize dust formation, wear personal protective equipment suited for powder handling, avoid direct contact
Hygiene Practices: Do not eat, drink, or smoke while working with L-Threonine, wash hands thoroughly after handling, keep work clothes separate
Storage Conditions: Store in tightly closed container in cool, dry, well-ventilated space, protect from moisture and incompatible materials like strong oxidizers, maintain original packaging integrity
Occupational Limits: No specific OSHA, ACGIH, or EU exposure limits established
Engineering Controls: Use local exhaust ventilation to minimize airborne concentrations, ensure eye wash stations and safety showers remain accessible
