Toxic by inhalation and if swallowed.Gives rise to hazardous decomposition products.


Chemical: Indium Phosphide
C.A.S. No.: 22398-80-7
Pure Compound:In: 78.8 wt%
                            P: 21.2 wt%


Inhalation: Remove patient from exposure. Obtain medical attention.Skin contact: Wash immediately with water. If symptoms occur, obtain medical attention.Eye contact: Irrigate with clean water or eyewash solution for at least 10 mins.Ingestion: Wash out mouth with water. Obtain immediate medical attention.


Extinguishing Media: Use dry extinguishers suitable for metal fires.
Special Hazards: Product will thermally decompose above 300℉evolving toxic vapours of phosphorus and oxides of phosphorus. Elemental phosphorus is flammable. Reaction with acid and/or steam may release Phosphine gas which is toxic and pyrophoric.
Protective Equipment:Wear full protective equipment and self-contained bre apparatus. Take measures appropriate for phosphorus


Personal precautions: Wear protective equipment including gloves and appropriate respiratory protection.
Evironment: Prevent any release to drains or water courses or emission of dust or fumes to air.
Spillages: Collect all material and transfer to closed container for disposal.


Handling: Do not breathe dust.When using do not eat, drink or smoke. Avoid contact with skin and eyes. Atmospheric concentrations should be controlled in compliance with the Occupational Exposure Standards. Use extraction and ventilation for cutting, grinding, polishing or etching operations. Do not allow clothes to become contaminated and use good hygiene practices.
Storage: Keep container closed in a cool, dry, well ventilated place.


Occupational Exposure Standards:
“Indium and Compounds” UK EH40: OES 0.1mg/m3 (8h TWA)
                                                           OES 0.3mg/m3 (15min ref.)
“Phosphorus, yellow” UK EH40:         OES 0.1mg/m3 (8h TWA)
                                                            OES 0.3mg/m3 (15min ref.)
Engineering Controls: Local exhaust ventilation for all mechanical or chemical processing perations. High efficiency dust filtration on extract exhaust outlets. Extract ducting may contain finely divided dust or particles. Maintenance of processing and extract equipment should be carried out using full personal protectve equipment.
Respiratory Protection: All processes should be carried out under extraction. Where high concentrations of dust or decomposition products are likely, air supplied breathing equipment should be used
Hand Protection: Rubber or plastic gloves. Flame-proof gloves if elemental phosphorus is present.
Eye protection: Face shield or safety glasses.


Appearance & Odour: Dark grey, odourless solid with vitreous lustre
Melting Point (℃): 1062
Density (kg/m3): 4.79
Vapour Pressure: Decomposes with P vapour pressure of 27 atmospheres at the melting temperature.
Solubility:Insoluble in water.


Stability: Decomposes to evolve phosphorus vapour if heated above 300℃.
Conditions to Avoid: Excessive heating.Materials to avoid: Reacts with strong acid reducing agents to produce highly toxic phosphine gas.
Hazardous Decomposition Products: Phosphorus (red and yellow) and oxides of phosphorus.


Acute: NIOSH #: NL1800000
Toxicity CODEN: ipr-mus LD50: >5000 mgkg JOCHFV
Main acute hazards from decomposition products, phosphine (TLV 0.3ppm), yellow phosphorus and phosphorus pentoxide.
Exposure Routes: Inhalation of dust, phosphine generated by chemical reaction or phosphorus oxides formed by heating in air.Ingestion of dust or particles
Chronic: Chronic effects of exposure to yellow P include bone necrosis of the jaw.


Mobility: The product is involatile and insoluble and will accumulate in the ground.Persistence: The product is expected to be resistant to biodegradation.Bio-accumulation: Not known.


Product Disposal: Surplus or waste product should be retained wherever possible for recycling. Solids subject to special disposal to landfill.
Container Disposal: Materials contaminated by contact with the product or its processing by-products should be dealt with as special wastes according to local regulatory requirements. Materials contaminated with elemental P should be stored under water or inert gas to avoid possible spontaneous combustion.


UN Number: Not restricted.
UN Hazard Class: Acute toxicity below range for classification
