Ingestion: Rinse mouth, never induce vomiting, obtain immediate medical attention
Note for Physicians: Treat symptomatically, remove source of exposure

5. Fire-Fighting Measures

Suitable Extinguishing Media: Dry sand, Class D fire extinguisher
Unsuitable Media: Water, foam, carbon dioxide not recommended for metal fires
Unusual Fire Hazards: Powdered or fine forms present a combustion hazard
Specific Hazards: Fire or extreme heat releases irritating metal oxide fumes
Protective Equipment: Full-face, self-contained breathing apparatus and heat-resistant gear
Advice for Firefighters: Prevent dust cloud formation, isolate material if possible

6. Accidental Release Measures

Personal Precautions: Wear particulate respirator, chemical-resistant gloves, safety goggles
Environmental Precautions: Prevent spillage into drains, water sources, or soil
Containment: Sweep up without generating dust, use inert tools for cleanup
Clean-Up Methods: Place powder in a closed, labeled container for disposal
Emergency Procedures: Restrict area, ventilate workplace, avoid dispersal of airborne particles

7. Handling and Storage

Safe Handling Advice: Avoid inhaling dust and fumes, use fume hoods for processing tasks
Minimize Dust Generation: Use local ventilation or wet machining
Storage Conditions: Store in tightly closed containers, cool, dry, well-ventilated area
Incompatible Materials: Strong oxidizers, strong acids, halogens
Protective Measures: Ground equipment to prevent static discharge, keep containers labeled
Other Precautions: Keep away from moisture to reduce risk of corrosion or reaction

8. Exposure Controls and Personal Protection

Occupational Exposure Limits: Molybdenum (TWA: 5 mg/m³, OSHA), Titanium and Zirconium limits based on respirable dust
Engineering Controls: Local exhaust ventilation, enclosures
Personal Protective Equipment: Dust mask/respirator, chemical goggles, flame-resistant gloves, antistatic clothing
Hygiene Measures: Wash hands after handling, remove contaminated clothing before breaks
Environmental Controls: Prevent release to the environment using spill containment methods

11. Toxicological Information

Routes of Exposure: Inhalation, skin and eye contact, ingestion (very rare)
Acute Effects: Dust and fumes can cause irritation to upper respiratory tract, skin irritation, and eye discomfort
Chronic Effects: Prolonged exposure may cause lung changes, rare cases of metal fume fever
Toxicity Data: No evidence of carcinogenicity for alloy; molybdenum and zirconium compounds considered low-toxicity in elemental state
Sensitization: Reports of allergic skin reactions from prolonged exposure
Medical Conditions Aggravated: Pre-existing respiratory disorders may worsen upon exposure to high concentrations of dust/fume
