Aluminium hydride

Hydrides of some metals (such as AsH3) are extremely toxic. Dangerous fire hazard. An unstable material which is spontaneously flammable in air or O2. Evolves explosive H2 upon contact with moisture. Severe explosion hazard by chemical reaction wherein H2 gas is produced, also in contact with methyl ethers contaminated by CO2. Mixtures with tetrazole derivatives are explosive. Reacts with oxidizing materials. On contact with acid or acid fumes, it can emit toxic fumes. See also HYDRIDES and ALUMINUM COMPOUNDS.
