First Aid Measures

Inhalation: Move to fresh air, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, wash exposed area with soap and water; medical consultation if rash or irritation remains
Eye Contact: Rinse with copious water for at least 15 minutes, seek professional attention if redness or discomfort develops
Ingestion: Rinse mouth with water, do not induce vomiting, seek immediate medical help or contact poison control
Most Important Symptoms: Local irritation, rare cases of systemic corticosteroid toxicity with extensive misuse
Advice to Physicians: Symptomatic and supportive care, monitor for adrenal suppression in rare overdose

Fire-Fighting Measures

Flammability: Not classified as flammable, burns if exposed to flame
Suitable Extinguishing Media: Water spray, carbon dioxide, dry chemical powder, foam
Hazards from Combustion: May release toxic fumes of carbon oxides and hydrogen fluoride if overheated
Protective Equipment: Full firefighting gear, self-contained breathing apparatus recommended
Special Procedures: Avoid breathing fumes, move product from fire area if safe to do so, cool exposed containers
Explosion Hazards: Dust generation may cause explosion risk in rare poorly ventilated cases

Accidental Release Measures

Personal Precautions: Wear gloves, safety glasses, gown or lab coat; ensure good ventilation
Environmental Precautions: Prevent spillage into waterways, use absorbent material for containment
Spill Clean Up: Mop or scoop up solid, clean affected surfaces with water and mild detergent, dispose as medical waste
Reporting: Notify health and safety management for significant spills

Handling and Storage

Handling: Use gloves, limit direct contact, avoid generating dust or aerosol, do not eat or drink while in use
Hygiene Measures: Wash hands thoroughly after handling, remove contaminated clothing immediately
Storage Conditions: Store tightly closed in cool, dry, well-ventilated area, protect from light and moisture
Incompatible Materials: Strong oxidizing agents, acids

Toxicological Information

Likely Routes of Exposure: Skin, eyes, inhalation, accidental ingestion
Acute Toxicity: No human LD50 established; animal data suggests low oral toxicity
Skin Irritation: Possible, especially on damaged or sensitive skin
Eye Irritation: Mild, transient
Inhalation: Unlikely unless powder is airborne, low risk of toxicity
Chronic Effects: Skin atrophy, adrenal suppression if misused or overused
Sensitization: Rare; monitor for rash or allergic reaction
