Chemical Properties
white or grey granules
Uses
To absorb carbon dioxide in basal metabolism tests, in rebreathing anesthesia systems, in submarines, and in carbon determinations.
General Description
Soda lime, solid is generally a white to grayish white colored solid. SODA LIME is the mixture of calcium hydroxide and sodium or potassium hydroxide, both corrosive materials. SODA LIME is noncombustible and soluble in water with release of heat. SODA LIME is corrosive to metals and tissue.
Air & Water Reactions
Soluble in water with release of heat.
Reactivity Profile
The reaction between hydrogen sulfide and soda lime is attended with incandescence in the presence of air. In oxygen there is an explosion. Mixtures of barium oxide with mercurous or nickel oxide also react vigorously with hydrogen sulfide in air. Explosions may result [Mellor 10:140 1946-47].
Health Hazard
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
Hazard
Toxic by ingestion and inhalation, strong
irritant to tissue.
