Useful:

• Chemical Classes: Metals -> Phosphides
• Canonical SMILES: [Al]#P
• Inhalation Risk: Evaporation at 20 °C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. Hydrolysis in atmospheric moisture or perspiration may yield gaseous phosphine which can be inhaled.
• Effects of Short Term Exposure: The substance is irritating to the eyes, skin and respiratory tract. Inhalation of decomposition products (phosphine) may cause lung oedema. The substance may cause effects on the cardiovascular system, nervous system, respiratory tract, liver and kidneys. This may result in impaired functions, respiratory failure, tachycardia and coma. Exposure could cause death.
• Description: Aluminum phosphide, is a binary salt, one of the NCHP acronyms (see Chapter 2). These salts have the specific hazard of giving off poisonous and pyrophoric phosphine gas when in contact with moist air, water, or steam. They will also ignite spontaneously upon contact with air. This compound is composed of gray or dark yellow crystals and is a dangerous fire risk. Aluminum phosphide decomposes upon contact with water and has a specific gravity of 2.85, which is heavier than water. The four-digit UN identification number is 1397. The NFPA 704 designation is health 4, flammability 4, and reactivity 2. The white section at the bottom of the diamond has a W with a slash through it, indicating water reactivity. Aluminum phosphide is used in insecticides, fumigants, and semiconductor technology.
• Uses: The primary use for AlP is as a fumigant to control insects and rodents in both food and nonfood crops in indoor environments. It is also used in the control of rodents outdoors via application to their burrows or in grain storage areas. Due to the extremelycommonuse of this compound for protecting rice, it is also called rice tablet in some countries. AlP is formulated in solid form and is available for use as a tablet, pellet, or dust. It is marketed as dark gray 3-g tablets consisting of AlP (56%) and carbamate (44%), under brand names such as Celphos, Alphos, Quickphos, Phosfume, Phostoxin, Talunex, Degesch, Synfume, Chemfume, Phostek, and Delicia in porous hags or blister packs. Source of phosphine; in semiconductor research; as fumigant.
