3.2 Experimental Properties

3.2.1 Physical Description

Mercuric sulfide appears as odorless red or black solid. Sinks in water. Insoluble in water.

3.2.2 Density

8 at 68 °F (USCG, 1999) - Denser than water; will sink

7 Safety and Hazards

7.1 Hazards Identification

7.1.1 Health Hazards

Acute poisoning can result from inhaling dust concentrations of 1.2-8.5 mg/m 3 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. (USCG, 1999)
U.S. Coast Guard. 1999. Chemical Hazard Response Information System (CHRIS) - Hazardous Chemical Data. Commandant Instruction 16465.12C. Washington, D.C.: U.S. Government Printing Office.

7.1.2 Fire Hazards

Special Hazards of Combustion Products: Smoke from fire contains poisonous mercury vapor and irritating sulfur dioxide gas.

Behavior in Fire: Changes color when hot. Decomposes at burning temperature. The black form may soften, and molten sulfur may flow out and burn. (USCG, 1999)

U.S. Coast Guard. 1999. Chemical Hazard Response Information System (CHRIS) - Hazardous Chemical Data. Commandant Instruction 16465.12C. Washington, D.C.: U.S. Government Printing Office.

7.2 First Aid Measures

7.2.1 First Aid

INHALATION: remove to fresh air; give artificial respiration if breathing has stopped.

INGESTION: give egg whites, milk, or activated charcoal; induce vomiting; consult physician.

EYES: flush with water.

SKIN: wash with soap and water. (USCG, 1999)

U.S. Coast Guard. 1999. Chemical Hazard Response Information System (CHRIS) - Hazardous Chemical Data. Commandant Instruction 16465.12C. Washington, D.C.: U.S. Government Printing Office.

7.3 Fire Fighting

Fire Extinguishing Agents Not to Be Used: Other agents may be ineffective.

Fire Extinguishing Agents: Water, foam, sand (USCG, 1999)

U.S. Coast Guard. 1999. Chemical Hazard Response Information System (CHRIS) - Hazardous Chemical Data. Commandant Instruction 16465.12C. Washington, D.C.: U.S. Government Printing Office.

7.4 Accidental Release Measures

7.4.1 Isolation and Evacuation

Excerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.

FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024)

7.5 Handling and Storage

7.5.1 Nonfire Spill Response

Excerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:

Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. Cover with plastic sheet to prevent spreading. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. For solids, prevent dust cloud and avoid inhalation of dust. (ERG, 2024)

7.6 Exposure Control and Personal Protection

7.6.1 Immediately Dangerous to Life or Health (IDLH)

10 mg Hg/m3 (NIOSH, 2024)

7.6.2 Personal Protective Equipment (PPE)

Dust mask; goggles or face shield; protective gloves (USCG, 1999)
U.S. Coast Guard. 1999. Chemical Hazard Response Information System (CHRIS) - Hazardous Chemical Data. Commandant Instruction 16465.12C. Washington, D.C.: U.S. Government Printing Office.

7.7 Stability and Reactivity

7.7.1 Air and Water Reactions

Readily oxidized as to be pyrophoric in air [Bretherick 1979. p. 120].

7.7.2 Reactive Group

Sulfides, Inorganic

7.7.3 Reactivity Alerts

Strong Reducing Agent

Pyrophoric

7.7.4 Reactivity Profile
