						  20°c): 8.64
Solubility: Insoluble in water; soluble in dilute
						  nitric acid and in sulfuric acid
Appearance: soft, blue-white, malleable, lustrous metal
						  or grayish-white powder.
B. Fire, Explosion and Reactivity Data
1. Fire
Fire and Explosion Hazards: The finely divided metal is
						  pyrophoric, that is the dust is a severe fire hazard and moderate explosion
						  hazard when exposed to heat or flame. Burning material reacts violently with
						  extinguishing agents such as water, foam, carbon dioxide, and halons.
Flash point: flammable (dust)
Extinguishing media: Dry sand, dry dolomite, dry
						  graphite, or sodium chloride.
2. Reactivity
Conditions contributing to instability: Stable when
						  kept in sealed containers under normal temperatures and pressure, but dust may
						  ignite upon contact with air. Metal tarnishes in moist air.
Incompatibilities: Ammonium nitrate, fused: reacts
						  violently or explosively with cadmium dust below 20°C. Hydrozoic acid:
						  violent explosion occurs after 30 minutes. Acids: reacts violently, forms
						  hydrogen gas. Oxidizing agents or metals: strong reaction with cadmium dust.
						  Nitryl fluoride at slightly elevated temperature: glowing or white
						  incandescence occurs. Selenium: reacts exothermically. Ammonia: corrosive
						  reaction. Sulfur dioxide: corrosive reaction. Fire extinguishing agents (water,
						  foam, carbon dioxide, and halons): reacts violently. Tellurium: incandescent
						  reaction in hydrogen atmosphere.
Hazardous decomposition products: The heated metal
						  rapidly forms highly toxic, brownish fumes of oxides of cadmium.
C. Spill, Leak and Disposal Procedures
1. Steps to be taken if the materials is released or
						  spilled.
Do not touch spilled material. Stop leak if you can do
						  it without risk. Do not get water inside container. For large spills, dike
						  spill for later disposal. Keep unnecessary people away. Isolate hazard area and
						  deny entry. The Superfund Amendments and Reauthorization Act of 1986 Section
						  304 requires that a release equal
						  to or greater than the reportable quantity for this substance (1 pound) must be
						  immediately reported to the local emergency planning committee, the state
						  emergency response commission, and the National Response Center (800) 424-8802;
						  in Washington, D.C. metropolitan area (202) 426-2675.

						  use a clean shovel to place material into clean, dry container and then cover.
						  Move containers from spill area. For larger spills, dike far ahead of spill for
						  later disposal. Keep unnecessary people away. Isolate hazard area and deny
						  entry. The Superfund Amendments and Reauthorization Act of 1986 Section
