4 hen heated above 580 C, material can decompose to produce Ca0. When this material is involved in a fire situation, firefighters should wear full protective clothing, and use eye protcetion and self-contained breathing apparatus.
SECTION V. REACTIVITY DATA This is a stable solid in a scaled container at room temperature. When exposed to the air it will absorb carbon dioxide and form calcium carbonate. When heated at t empe ra tu res above 580 C, it loses water to fom calcium oxide or line.
Calcium hydroxide is a strongly alkaline r.2terial which is incompatible with acidic ma-terials.
It forms salts with nitroparaf fins in the presence of water which are explo-sive when dried. It can cause the explosive decomposition of calcic anhydride. BoilinE elemental phosphorus in a calcium hydroxide solution can liberate spontaneously flam-ruble phosphines.

Dilute by giving 2 glasses of water er milk to drink, followed by fruit juir.e or diluted vinegar to neutralize the alkali; then, consult physician.
SECTION VII. SPILL, LEAK, AND DISPOSAL PROCEDURES Those involved in clean up of spills should use protective equip =ent (See Sect. VIII) .
Pick up spilled powder avoiding dustine conditions and place in a clean steel container for disposal. Safety personnel should be involved when large spills occur. Traces of residue can be flushed to the sewer, but neutralization before flushing may be required DISPOSAL: Follow Federal, State and local regulations for disposai. r Consider the fol-lowing methods of disposing of scrap material: Use to neutralize waste acid or spread on surface of ground in an isolated, protected area to react with CO 2 from t 2 air to form CACO 3 (limestone); or disperse in water, neutralize with hydrochloric acid cipitateliter.

This material is stable under normal storage conditiois in a sealed container. No polymerization will occur; there are not hazardous decomposition products.
It will react with CO2 in the air (when exposed) to form sodium carbonate.
It will react violently with acids and with many organic chemicals, especially nitrocarbons, and halocarbons. (Trichloroethylene will react to form spontaneous: y flac.nable dichloroacetylene).
