Mercury (organo) alkyl compounds (as Hg)
PHYSICAL DESCRIPTION: Light cream-colored crystalline powder with a slight odor: pH (1% aqueous solution) 6.7. Slight odor. (NTP, 1992)
Air & Water Reactions
Flash point data for this chemical are not available; however, it is probably combustible. (NTP, 1992)
SYMPTOMS: Symptoms of exposure to this class of compounds includes aphthous stomatitis, catarrhal gingivitis, nausea, liquid stools, pain, liver disorder, injury to the cardiovascular system and hematopoietic system, deafness and ataxia. Exposure may be fatal. Headache, paresthesia of the tongue, lips, fingers and toes, other non-specific dysfunctions, metallic taste, slight gastrointestinal disturbances, excessive flatus and diarrhea may occur. Acute poisoning may cause gastrointestinal irritation and renal failure. Earl signs of severe poisoning include fine tremors of extended hands, loss of side vision, slight loss of coordination in the eyes, speech, writing and gait, inability to stand or carry out voluntary movements, occasional muscle atrophy and flexure contractures, generalized myoclonic movements, difficulty understanding ordinary speech, irritability and bad temper progressing to mania, stupor, coma, mental retardation in children, skin irritation, blisters and dermatitis. Other symptoms include chorea, athetosis, tremors, convulsions, pain and numbness in the extremities, nephritis, salivation, loosening of the teeth, blue line on the gums, anxiety, mental depression, insomnia, hallucinations and central nervous system effects. Exposure may also cause irritation of the eyes, mucous membranes and upper respiratory tract.
ACUTE/CHRONIC HAZARDS: This compound is toxic by ingestion and inhalation. It is an eye irritant. When heated to decomposition it emits very toxic fumes of mercury, sodium oxide and sulfur oxides. (NTP, 1992)
MERCURY((O-CARBOXYPHENYL)THIO)ETHYL, SODIUM SALT is incompatible with strong oxidizing agents and strong bases. The oxidation of this compound is greatly accelerated by traces of copper ions. Incompatible with acids, iodine, heavy metal salts and many alkaloids. Can be absorbed by rubber caps. (NTP, 1992). Stable in air, but not sunlight. May discolor on exposure to light. Dilute aqueous solutions are fairly stable to heat but sensitive to light. Solutions are less stable to heat when acidic than when alkaline. Solutions are most stable to light at pH 5 to 7. Solutions are unstable to heat but not to light in the presence of copper, iron or zinc ions but not in the presence of calcium or magnesium ions.

Isolation and Evacuation
Excerpt from ERG Guide 151 [Substances - Toxic (Non-combustible)]:
As an 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, in the downwind direction, as necessary, the isolation distance shown above.
FIRE: If tank, rail car or tank truck 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, 2016)
Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. A water spray may also be used. (NTP, 1992)
SMALL SPILLS AND LEAKAGE: If you spill this chemical, you should dampen the solid spill material with water, then transfer the dampened material to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all contaminated surfaces with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.
STORAGE PRECAUTIONS: You should protect this compound from light and store it under ambient temperatures. (NTP, 1992)
RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.
INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. IMMEDIATELY call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.
INGESTION: Some heavy metals are VERY TOXIC POISONS, especially if their salts are very soluble in water (e.g., lead, chromium, mercury, bismuth, osmium, and arsenic). IMMEDIATELY call a hospital or poison control center and locate activated charcoal, egg whites, or milk in case the medical advisor recommends administering one of them. Also locate Ipecac syrup or a glass of salt water in case the medical advisor recommends inducing vomiting. Usually, this is NOT RECOMMENDED outside of a physician's care. If advice from a physician is not readily available and the victim is conscious and not convulsing, give the victim a glass of activated charcoal slurry in water or, if this is not available, a glass of milk, or beaten egg whites and IMMEDIATELY transport victim to a hospital. If the victim is convulsing or unconscious, do not give anything by mouth, assure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)
