MERCURIC ACETATE 243

Fire Hazards -Flash Point (deg. F): (liquid) 215 CC; 230 OC; FhnmbleLimits in Air (96): 1.4-7.1;
Fire Extinguishing Agents: Alcohol foam, dry chemical, or carbon dioxide; Fire Extinguishing Agents
Not To Be Used: Water or foam may cause frothing; Special Hazards of Combustion Products: Not
pertinent; Behavior in Fire: When heated above 300°F in the presence of various materials may
generate heat and carbon dioxide. Will explode if confined; Ignition Temperature (deg. F): 878;
Electrical Hazard: Class I, Group D; Burning Rate: 1.4 mm/min.
Chemical Reactivity - Reactivity with Water: Hot water may cause frothug. Reaction with cold water
is slow and non-hazardous; Reactivity with Common Materials: No reaction; Stability During Transpoi?:
Stable; hkutralizing Agents for Acids and Caustics: Solid spills can usually be recovered before any
significant reaction with water occurs. Flush area of spill with water; Polymerization: Very unlikely
at ordinary temperatures, even in the molten state; Inhibitor of Polymerization: None.
