At room temperature, it does not react with air, but it can have oxidation reaction at above 350 ℃, and have reaction with nitrogen at 600~700 ℃ to generate calcium cyanamide. Calcium carbide, when coming across with water or steam, generates acetylene and release a large amount of heating.

Experiments | SpringerLink

Do not extinguish fires of alkaline metals with water, but with sand. Alkaline metals are stored in kerosene because oxygen and carbon dioxide of the air or water vapor in the air react with these metals to form oxides, carbonates or hydroxides. At room temperature calcium reacts to an alkaline solution: calcium hydroxide solution
