Inhalation: Move to fresh air, rest, monitor for respiratory distress; seek medical advice if symptoms persist
Skin Contact: Remove contaminated clothing; wash skin with plenty of soap and water; seek medical attention for persistent irritation
Eye Contact: Rinse immediately with plenty of water, lifting eyelids—keep rinsing for several minutes; remove contact lenses if easy, continue rinsing; get medical help if irritation remains
Ingestion: Rinse mouth, drink water, do not induce vomiting; consult a physician if feeling unwell
Most Important Symptoms: Coughing, sneezing, mild irritation, redness or burning in eyes, skin dryness, gastrointestinal discomfort
Note to Physicians: Treat symptomatically; monitor for delayed respiratory effects
Suitable Extinguishing Media: Use dry chemical, foam, or sand; avoid water, as phosphorus may react
Unsuitable Media: Water jets, as these can spread fire or react with phosphorus
Specific Hazards: Product may emit toxic fumes during combustion—phosphine gas and oxides
Special Protective Equipment: Firefighters should wear self-contained breathing apparatus and complete protective equipment
Advice for Firefighters: Cool adjacent containers with non-direct water spray, prevent run-off into drains, evacuate area in case of large fire
Additional Info: Fine dust may form explosive mixtures with air; container explosion hazard
Personal Precautions: Evacuate non-essential personnel, avoid dust formation, ventilate affected area, use respiratory protection as needed
Environmental Precautions: Prevent spill from entering drains, soil, watercourses; notify local authorities in case of significant release
Methods for Cleanup: Collect mechanically using non-sparking tools, place in clearly labeled containers for disposal or recycling; avoid creating airborne dust; wash area with water after material is collected
Reference to Other Sections: Refer to Exposure Controls and Disposal Considerations
Safe Handling: Keep away from heat, sparks, open flames; avoid breathing dust; use grounding and bonding during material transfer; avoid contact with skin and eyes; ensure proper ventilation
Hygiene Measures: Wash hands after handling, do not eat, drink, or smoke in work area
Storage Requirements: Store in a cool, dry, well-ventilated place away from incompatible materials such as oxidizers and acids; keep container tightly closed; store away from direct sunlight or sources of ignition
Specific End Uses: Intended for industrial processing, not for consumer application
Occupational Exposure Limits: Red phosphorus TWA (8hr): 0.1 mg/m³ (OSHA/NIOSH); No established polyamide exposure limits
Engineering Controls: Use local exhaust ventilation, enclosed processes where possible, dust collection systems
Personal Protection – Respiratory: Wear dust masks or respirators (N95 or higher) if exposure risk is significant
Personal Protection – Skin and Body: Wear impervious gloves, long-sleeved work clothing
Personal Protection – Eyes: Safety glasses with side shields or chemical goggles
Environmental Controls: Prevent environmental discharge, monitor regularly for airborne concentration
Appearance: Granular, pelletized solid, reddish to dark brown color
Odor: Odorless or faintly characteristic
Melting Point: Above 180°C (due to polymer base)
Boiling Point: Not applicable
Density: Approx. 1.2–1.4 g/cm³
Solubility: Insoluble in water
Flash Point: Above 300°C
Explosion Properties: Dust may be explosive
Vapor Pressure: Negligible
Auto-ignition Temperature: Around 260–300°C depending on formulation
Partition Coefficient: Not relevant
Decomposition Products: Phosphine gas, oxides, hydrocarbons
Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: Can react with oxidizing agents, acids, strong bases
Conditions to Avoid: High temperatures, open flames, static discharge, incompatible materials
Incompatible Materials: Strong oxidizers, halogens, acids
Hazardous Decomposition Products: Phosphine, toxic phosphorus oxides, carbon monoxide-dioxide, organic vapors
Hazardous Polymerization: Not expected under normal use
Possible Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Effects: Can cause coughing, throat, eye, or skin irritation
Chronic Effects: Long-term or repeated inhalation may cause respiratory tract effects; evidence of systemic toxicity at high or prolonged exposures
LD50 (Oral): Red phosphorus approximate LD50 (rat): 640 mg/kg
Skin Sensitization: No strong evidence of skin sensitization
Carcinogenicity: No listing for red phosphorus in IARC, ACGIH, NTP, or OSHA
Mutagenicity: Not expected based on available data
Other Effects: Inhalation of dust may worsen symptoms in those with respiratory disease
Aquatic Toxicity: Harmful to aquatic life (chronic); polyamide matrix reduces environmental mobility; phosphorus poses risks to aquatic organisms if released
Mobility in Soil: Low, granules settle out and embed in soil
Persistence and Degradability: Polyamide carrier is slow to degrade; phosphorus is persistent in the absence of energetic oxidizers
Bioaccumulative Potential: Expected to be low; phosphorus and polyamide do not easily bioaccumulate
Other Adverse Effects: Possible long-term hazard to water bodies from runoff or improper disposal
Waste Treatment Methods: Dispose of material through incineration or licensed waste handlers; do not release to sewers or environment
Regulations: Follow all federal, state, and local regulations for disposal; treat as hazardous waste where local rules apply
Packing for Disposal: Use sealed, labeled containers; material may be recycled if not contaminated
Contaminated Packaging: Dispose as hazardous waste or as required by local regulations
