First Aid Measures

General Advice: Obtain medical attention if symptoms occur or persist.
If Inhaled: Move to fresh air, keep at rest in a position comfortable for breathing, seek medical attention for persistent discomfort.
If On Skin: Remove contaminated clothing, rinse skin immediately with running water for at least 15 minutes, seek medical attention if skin irritation or rash develops.
If In Eyes: Flush eyes with plenty of water for at least 15 minutes, lifting eyelids occasionally, remove contact lenses if present and easy to do, seek medical attention.
If Swallowed: Rinse mouth with water, do not induce vomiting, call poison control center or physician immediately.

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, foam, dry chemical powder, carbon dioxide (CO2)
Specific Hazards Arising: May emit selenium oxides and carbon oxides under fire conditions
Special Protective Equipment: Firefighters wear self-contained breathing apparatus and full protective gear
Advice for Firefighters: Approach fire from upwind to avoid hazardous vapors and thermal decomposition products
Explosion Data: Not sensitive to mechanical impact or static discharge; dust may generate explosion hazard in rare cases if accumulations reach flammable levels in confined spaces

Accidental Release Measures

Personal Precautions: Wear gloves, eye protection, dust mask; prevent contact with skin and eyes; ensure adequate ventilation
Environmental Precautions: Prevent runoff into surface water, soil, and the sewage system; notify authorities if larger spills cannot be contained
Cleanup Methods: Avoid raising dust, sweep up material and place in a clearly labelled waste container for proper disposal, wash area with water and detergent to remove residues, avoid release to the environment

Handling and Storage

Handling: Avoid ingestion, inhalation, direct contact with eyes, skin, or clothing; keep away from food, drink, and animal feeding stuffs; wear recommended personal protective equipment
Storage: Store in tightly sealed container in a cool, dry, well-ventilated location; keep away from direct sunlight, incompatible materials, excessive heat, acids, and oxidizers; segregate from food and drink products

Exposure Controls and Personal Protection

Exposure Limits: OSHA PEL (total selenium): 0.2 mg/m3 TWA; ACGIH TLV: 0.2 mg/m3 TWA for selenium compounds

Toxicological Information

Acute Toxicity: Oral LD50 (rat): 7–15 mg/kg (as selenium); potential for toxic effects at low doses
Chronic Toxicity: Long-term or repeated exposure can impact liver, kidneys, gastrointestinal tract, and central nervous system
Skin Corrosion/Irritation: Causes irritation with redness or rash upon contact
Serious Eye Damage/Irritation: Causes eye irritation; redness, pain, or damage with direct exposure
Respiratory or Skin Sensitization: Prolonged contact may trigger allergic reactions in sensitive individuals
Carcinogenicity: Not classified as a carcinogen by NTP, IARC, OSHA
Reproductive Toxicity: Overexposure to selenium compounds has been linked to reproductive risks in animal studies; insufficient evidence in humans

Ecological Information

Ecotoxicity: Highly toxic to aquatic organisms; potential to bioaccumulate and impact aquatic food chains
Persistence and Degradability: Not readily biodegradable; selenium compounds persist and may transform to other selenium species through microbial action
Bioaccumulative Potential: Selenium accumulates through food webs and can become toxic at higher trophic levels
Mobility in Soil: Moderate potential; selenium salts can leach through soil and contaminate groundwater
Other Adverse Effects: Discharge to the environment must be prevented; follow local authority guidelines

Disposal Considerations

Disposal Methods: Treat as hazardous waste; incinerate in authorized facility or treat chemically according to local, regional, and national regulations
Contaminated Packaging: Dispose of as unused product; do not reuse containers unless thoroughly cleaned and inspected
Disposal Precautions: Avoid discharge to the environment; notify regulatory authorities in the event of significant spill or contamination incident
