First Aid Measures

Inhalation: Move person to fresh air; administer oxygen if breathing is difficult; seek medical advice immediately for any persistent discomfort or respiratory symptoms
Skin Contact: Remove any contaminated clothing; wash area thoroughly with soap and water; seek medical advice if irritation or allergic response develops
Eye Contact: Rinse cautiously with water for at least 15 minutes, keeping eyelids open; remove contact lenses if present and easy to do; get medical attention
Ingestion: Rinse mouth with water; do not induce vomiting; seek prompt medical attention; provide symptomatic and supportive care
Note to Physician: Monitor for allergic symptoms and treat as anaphylaxis if severe reaction occurs; consider corticosteroids and antihistamine therapy if indicated

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, dry powder, carbon dioxide, foam
Unsuitable Extinguishing Media: Do not use high-volume water jet in confined spills
Specific Hazards: Combustion may release nitrogen oxides, sulfur oxides, carbon monoxide, and other toxic fumes
Firefighter Protection: Use self-contained breathing apparatus and protective clothing in hazardous conditions; approach from upwind to avoid exposure to combustion gases
Explosion Risk: Not classified as explosive, dust in high concentrations may form explosive mixtures with air

Accidental Release Measures

Personal Precautions: Avoid contact with skin and eyes; wear personal protective equipment including gloves, goggles, and particulate respirator
Emergency Procedures: Restrict access to contaminated area; ventilate location; evacuate any unnecessary personnel
Environmental Precautions: Prevent spill from entering drains, surface water, or soil; contain any runoff with inert material such as earth or sand
Cleaning Methods: Collect solid material by vacuum or careful sweeping; clean contaminated area with damp cloth and dispose of all cleaning materials as hazardous waste; avoid creating dusty conditions

Handling and Storage

Handling: Avoid contact with skin, eyes, and clothing; do not inhale dust; handle in well-ventilated area or fume hood when possible; use dedicated equipment to limit potential for cross-contamination
Hygiene Measures: Wash hands thoroughly after handling; do not eat, drink, or smoke in the work area; remove contaminated clothing and wash before reuse
Storage: Store in tightly sealed containers, protected from light, moisture, and incompatible materials; keep at 2–8°C in dry conditions; segregate from strong acids, bases, and oxidizers
Packaging Materials: Use chemically compatible, sealed, and labeled packaging

Exposure Controls and Personal Protection

Exposure Guidelines: No established occupational exposure limit; minimize exposure to dust
Engineering Controls: Use local exhaust ventilation, process enclosures, or chemical fume hood for dust control
Personal Protective Equipment: Nitrile gloves, lab coat, chemical safety goggles, disposable dust mask or N95 respirator
Environmental Controls: Prevent material from escaping into environment by using proper waste and air filtration systems
Work Practices: Use nonbreakable containers, minimize dust generation, keep containers closed except during transfer, label all working solutions clearly

Mutagenicity/Teratogenicity: No data indicating genotoxicity or developmental risks
Other Information: Medical surveillance may be advisable in workplaces with repeated use; avoid long-term contact

Ecological Information

Ecotoxicity: Not expected to be highly toxic to aquatic organisms; data limited, but antibiotic intermediates often require containment to prevent resistance spread
