Eye Contact: Rinse carefully with plenty of water, lift eyelids to ensure thorough washing, consult an eye specialist if redness or discomfort remain
Ingestion: Rinse mouth, do not induce vomiting, drink water if conscious, seek prompt medical help
Suitable Extinguishing Agents: Dry chemical powder, foam, or carbon dioxide; avoid water spray near the source due to possible reaction
Specific Hazards: May release phosphine gas, toxic fumes of phosphorus oxides and aluminum oxide in fire
Special Protective Equipment: Full protective clothing, self-contained breathing apparatus
Firefighting Instructions: Move containers from fire area if safe, prevent runoff from entering drains, stay upwind, cool containers exposed to heat
Personal Precautions: Wear protective clothing, use proper ventilation
Environmental Precautions: Prevent spill from reaching soil, waterways, or drains
Spill Clean-up Methods: Scoop up spilled material, avoid generating dust, collect in sealable container for disposal, wash spill site after cleanup
Handling: Use with adequate air flow, avoid creating dusts or aerosols, wear gloves and goggles, wash hands after use
Storage Conditions: Store in tightly closed containers, keep in dry, cool place away from heat or flame, segregate from strong oxidizers, acids, and moisture
Incompatible Materials: Strong acids, oxidizers, bases, water sources
Occupational Exposure Limits: No OSHA or ACGIH threshold limit values specifically established
Engineering Controls: Local exhaust ventilation, eyewash stations, accessible safety shower
Personal Protective Equipment: Chemical-resistant gloves, safety goggles, lab coat, NIOSH-approved respirator if dust exposure is significant
Hygiene Measures: Wash hands and face before breaks and after work, do not eat, drink or smoke when handling material
Appearance: White to off-white fine powder
Odor: Odorless or slightly pungent
pH (aqueous suspension): Approx. 3-4
Melting Point: Decomposes above 250°C
Boiling Point: Not applicable (decomposes on heating)
Solubility: Slightly soluble in water, more soluble in acids
Density: Approx. 2.1 g/cm³
Other Properties: Stable under recommended storage conditions
Reactivity: Reacts with strong oxidizers, acids, possibly with water if not protected
Chemical Stability: Stable under normal temperatures and pressure in dry conditions
Hazardous Decomposition: Yields phosphine, aluminum oxide, and phosphorus oxides in decomposition or fire
Polymerization: No known hazardous polymerization
Conditions to Avoid: Heat, humidity, contact with incompatible substances
Likely Routes of Exposure: Inhalation, ingestion, contact with skin and eyes
Acute Effects: Skin and eye irritant, can cause respiratory discomfort if inhaled, nausea/vomiting if swallowed
Chronic Effects: No concrete data for chronic toxicity, use caution to minimize exposure
Carcinogenic Status: Not listed as a carcinogen by IARC, NTP, or OSHA
Ecotoxicity: Toxic to aquatic life, can cause long-term adverse environmental impacts
Persistence and Degradability: Expected to be persistent in aquatic environments, slow degradation
Bioaccumulation Potential: Low mobility, may not bioaccumulate to concerning levels in higher organisms
Mobility in Soil: Binds with soil components, risk for groundwater limited by low solubility
Other Adverse Effects: Spills increase risk for algal bloom or harm to water-based organisms in contaminated areas
