Carbide salts, incompatibilities with

HgjCU Noncombustible solid. Violent reaction with sodium. Slow decomposition in light, forming mercury and mercuric chloride. Incompatible with acetylene, alkali chlorides, ammonia, bromides, azides, carbonates, chlorine dioxide, cocaine hydrochloride, cyanides, copper and copper salts, hydrogen peroxide, hydroxides, iodides, iodine, iodoform, lead salts, lithium, potassium iodide, mbidium, silver salts, sodium carbide, sulfates, sulfides, sulfites. On small fires, use any kind of extinguishers. 

CALCIUM CARBIDE (75-20-7) Contact with water, moist air, steam, alcohols forms explosive acetylene gas, corrosive calcium hydroxide, and heat. Violent reaction with acid, acid fumes, copper salts, strong oxidizers (bromine, chlorine, iodine, etc.), iron trichloride, tin dichloride, silver nitrate. Incompatible with oxidizers, hydrogen chloride, methanol, copper salt solutions, lead fluoride, magnesium, selenium, sodium peroxide, stannous chloride, sulfur. 

LAPIS INFERNALIS (7761-88-8) A powerful oxidizer. Forms friction- and shock-sensitive compounds with many materials, including acetylene, anhydrous ammonia (produces compounds that are explosive when dry), 1,3-butadiyne, buten-3-yne, calcium carbide, dicopper acetylide. Contact with hydrogen peroxide causes violent decomposition to oxygen gas. Violent reaction with chlorine trifluoride, metal powders, nitrous acid, phosphonium iodide, red or yellow phosphorus, sulfur. Incompatible with acetylides, acrylonitrile, alcohols, alkalis, ammonium hydroxide, arsenic, arsenites, bromides, carbonates, carbon materials, chlorides, chlorosulfonic acid, cocaine chloride, hypophosphites, iodides, iodoform, magnesium, methyl acetylene, phosphates, phosphine, salts of antimony or iron, sodium salicylate, tannic acid, tartrates, thiocyanates. Attacks chemically active metals and some plastics, rubber, and coatings.
