1.Reactivity Profile: Inorganic reducing agents, such as Mercury(II) sulfide , react with oxidizing agents to generate heat and products that may be flammable, combustible, or otherwise reactive.
2.Health Hazard :Acute poisoning can result from inhaling dust concentrations of 1.2-8.5 mg/m3 in air; symptoms include pain and tightness in chest, coughing, and difficulty in breathing. If ingested, toxicity depends on release of t he Hg ++ ion; chronic mercury poisoning can cause kidney, mental, and nervous disturbances. Dust irritates eyes and frequently causes allergic dermatitis; absorption through skin can cause systemic poisoning.
