Advice for Doctors: Treat symptoms, no specific antidote required, symptomatic care rarely needed
Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide
Unsuitable Extinguishing Media: High pressure water streams may disperse dust
Hazards from Combustion: May produce nitrogen oxides, carbon monoxide, and carbon dioxide
Special Protective Equipment: Firefighters need standard protective gear and self-contained breathing apparatus
Specific Methods: Move containers from fire zone if safe, avoid inhaling combustion fumes
Explosion Data: Fine dust can rarely form explosive mixture with air under high concentration
Personal Precautions: Wear gloves, goggles, dust mask if large spill
Environmental Precautions: Prevent entry into sewers, water sources, or soil
Methods for Cleaning Up: Sweep or vacuum up without raising dust, collect in labeled containers, ventilate area
Handling Spilled Material: Clean surfaces with damp cloth to reduce residual dust risk
Safe Handling: Minimize dust formation, avoid breathing particulates, maintain good hygiene
Storage Conditions: Store in tightly closed containers, away from incompatible substances
Incompatibles: Strong oxidizing agents can react with amino acids
Storage Temperature: Recommended between 15°C–25°C, keep container dry
Further Notes: Keep away from food and beverages, label all storage vessels clearly
Control Parameters: No occupational exposure limits set for alanine
Engineering Controls: Handle in well-ventilated area, use local exhaust if dusting occurs
Personal Protection: Protective gloves, goggles, laboratory coat, dust mask if high dust levels
