First Aid Measures

Inhalation: Move to fresh air, keep at rest in comfortable position, seek medical attention if cough or irritation persists
Skin Contact: Remove contaminated clothing, wash skin well with mild soap and water; persistent irritation requires medical advice
Eye Contact: Flush gently with water for 15-20 minutes, keeping eyelids open, remove contact lenses if present and easy to do, consult medical personnel if discomfort lingers
Ingestion: Rinse mouth, avoid inducing vomiting, seek immediate medical attention, show label or packaging if possible
Notes for Medical Personnel: Treat symptomatically, monitor for delayed reaction due to irritation from dust exposure

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Extinguishing Media: Avoid powerful water jets which may spread powder
Specific Hazards: May release irritating phosphorus oxides or zinc oxides under high heat
Firefighters Advice: Use self-contained breathing apparatus, protect against fumes and smoke, spray contaminated materials after extinguishing to cool hot surfaces
Explosion Data: Non-explosive under normal conditions, keep dust concentrations low to avoid static ignition risk
Decomposition Products: Burning produces phosphorus oxides, zinc compounds, potential for toxic fume inhalation

Accidental Release Measures

Personal Protection: Wear respiratory protection, safety goggles, gloves, and avoid dust inhalation
Environmental Precautions: Prevent powder from entering drains or natural waterways, avoid soil contamination, contain spill with barriers as necessary
Cleaning Up Method: Sweep powder with minimal dust generation, use vacuum system with HEPA filter if necessary, place swept product into properly labeled disposal containers, wash spill area with water under controlled conditions
Handling Debris: Handle spilled material as hazardous waste, inform environmental authorities if substantial release occurs

Handling and Storage

Handling Precautions: Avoid breathing dust or vapors, use only outdoors or in well-ventilated areas, use personal protection recommended for industrial chemicals
Safe Storage Conditions: Keep containers tightly closed in a cool, dry, well-ventilated area away from sunlight and incompatible substances such as oxidizers or acids
Packaging Advice: Store in original packaging or chemically resistant containers clearly labeled
Other Considerations: Isolate from foodstuffs, beverages, and feeding stock, keep away from children and unauthorized personnel

Exposure Controls and Personal Protection

Occupational Exposure Limit: Not specifically established, limit dust to threshold set for nuisance particulates (e.g., ACGIH TLV for particulate matter)
Engineering Controls: Local exhaust ventilation, process enclosure, dust collection systems on equipment
Personal Protective Equipment: Respirator suitable for dust, chemical safety goggles, impervious gloves (nitrile, neoprene), protective clothing like lab coat or coveralls
Hygiene Measures: Wash hands and face thoroughly after handling, do not eat, drink, or smoke when using the product, remove contaminated clothing before entering eating areas
Workplace Monitoring: Periodically monitor airborne concentrations to ensure limits aren't exceeded, ensure safety showers and eyewash stations are nearby

Physical and Chemical Properties

Appearance: Fine white crystalline powder
Odor: Faint or none
pH: Neutral in water suspension
Melting Point: Decomposes before melting (actual temperature varies by grade, often >300°C)
Density: ~1.5-1.6 g/cm³ (approximate, batch-dependent)
Solubility: Practically insoluble in water, soluble in some organic solvents
Vapor Pressure: Negligible at room temperature
Partition Coefficient (n-octanol/water): Not determined
Boiling Point: Not applicable (decomposes prior to boiling)
Flash Point: Not flammable
Explosive Properties: Not classified as explosive, low risk under recommended handling

Stability and Reactivity

Chemical Stability: Stable under normal ambient and recommended handling and storage practices
Reaction Hazards: Reacts with strong oxidizing agents and acids to release phosphorus oxides or hazardous gases
Hazardous Decomposition: Thermal decomposition can create toxic fumes, including phosphorylation and zinc compounds
Polymerization: Will not polymerize
Special Conditions: Avoid exposure to excessive heat, ignition sources, strong acids and oxidizers

Toxicological Information

Expected Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Effects: Dust may cause respiratory tract irritation, short-term eye, and skin irritation
Chronic Effects: No human data on chronic exposure; animal studies suggest low systemic toxicity at occupational exposure levels
Carcinogenicity: Not listed by IARC, NTP, OSHA as human carcinogen
Mutagenicity: Not expected based on available information
Symptoms: Eye redness, sneezing, throat irritation, cough if powder suspends in air
Other Information: Individuals with pre-existing respiratory conditions might be more susceptible to acute symptoms from dusty workspaces

Ecological Information

Ecotoxicity: Expected to be low toxicity for aquatic invertebrates and fish based on analogous substances, may accumulate in sediment due to low solubility
Mobility: Not highly mobile in soil or water, likely settles out of suspension
Persistence and Biodegradability: Stable compound, unlikely to degrade rapidly in environment
Bioaccumulation: Not known to bioaccumulate, poor solubility limits uptake by aquatic organisms
Degradability: Degrades slowly in water, may persist in sediments over months or years
Precaution: Prevent bulk spills from entering waterways, sewage, or soil to limit environmental impact

Disposal Considerations

Waste Handling: Collect and place in suitable containers for disposal according to local, regional, and national regulations
Disposal Methods: Incinerate in facility with exhaust gas scrubbing, chemically treat if possible, landfill where permitted if no other safe option
Container Disposal: Empty containers fully before disposal, triple rinse and remove labels if reusing or recycling
General Advice: Do not mix with regular trash or flush to sewer; consult hazardous waste management authorities

UN Number: Not classified as dangerous goods by international transport regulators (ADR/RID, IMDG, IATA)
Proper Shipping Name: Zinc Diethylphosphinate, not regulated
Transport Hazard Class: Non-hazardous for road, rail, sea, air
Packing Group: Not assigned
Labels Required: None required for standard shipments
