Thio and dithiocarbamates slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids. Insoluble in water.

Flash point data for this chemical are not available; however, it is probably combustible. (NTP, 1992)

SYMPTOMS: Symptoms of exposure to a related compound include reddening and swelling of the eyes and skin, blisters, tearing, runny nose, dry throat and chest discomfort. Inhalation may cause sneezing and coughing. Other symptoms include irritation of the skin, eyes, mucous membranes and respirator tract. Exposure can cause conjunctivitis, erythema, rapid pulse, dizziness, urticaria, intolerance to alcohol, palpitation and hypotension. It may also cause vasodilation of the face and neck, tachycardia, tachypnea, cardiac arrhythmias, pallor, hypertension, convulsions, myocardial infarction, optic neuritis, peripheral neuropathy, hypersensitivity hepatitis, fatigue, sleepiness, headache, chromosomal aberrations (rare) and damage in the nerve cells of the cerebral cortex. Other symptoms include clinical and subclinical liver dysfunction and asthenia, thoracic pain, skin lesions, myocardial dystrophia and enlargement of the thyroid. It may cause reduced potency, gastrointestinal disorders, unpleasant taste, lowered blood pressure, mild confusion, lethargy, impaired memory span, bizarre behavior, emotional lability, ataxia, hallucinations, uncontrollable arm movements, irritability, speech difficulty, drowsiness, loss of libido, psychoses (rare), Parkinsonian tremor, neuropsychiatric effects, anorexia, weight loss, emesis, coma, delirium, catatonia, suppression of the tendon reflexes, hypotonia, flaccid paralysis and death. It may also cause hyperventilation, sweating, breathlessness, air hunger, chest pain, central nervous system depression and rash. Pulmonary damage may also occur. Diarrhea and allergic eczema have been reported. Photophobia and skin sensitization are also symptoms. Inhalation of a related compound after alcohol consumption has caused nausea, vomiting and flushing. It also causes collapse. Other symptoms following alcohol ingestion include gastric pain, hyperirritability, fine tremor of the fingers and tongue, elevated blood pressure, slight fever, moderate lymphopenia; albumin, urobilinogen and numerous casts in the urine, liver enlargement, ulcers of the oral cavity and goiters. Symptoms of exposure to this type of chemical may include abdominal pain or discomfort, colic, constipation, metallic taste, nausea, vomiting, lassitude, insomnia, weakness, joint and muscle pains, lead line on the gums, pyorrhea, abdominal tenderness, basophilic stippling, anemia, slight albuminuria and increased urinary excretion. Other symptoms of exposure to this type of chemical may include black stools, oliguria, collapse, apathy, loss of recently developed skills, nervousness, vague pains in the arms and legs, incoordination, sensory disturbances of the extremities, paralysis of extensor muscles of arms and legs with wrist and foot drop, disturbance of menstrual cycle, abortion, stupor, encephalopathy, papilledema and paralysis of the cranial nerves. Exposure may also cause nightmares, muscular weakness, restlessness, anxiety, hypothermia, bradycardia, delusions, exaggerated muscular movements and a maniacal state. It may also cause seizures and cardiorespiratory arrest. Chronic exposure may cause severe damage to blood-forming, nervous system, urinary and reproductive systems; excessive tiredness numbness, hyperactivity, damage to the central nervous system, feeling of dull ness, kidney disease, permanent kidney damage, birth defects, stillbirth and decreased hemoglobin. It causes decreased sex drive, impotence and sterility in men. In women, it may cause decreased fertility.

ACUTE/CHRONIC HAZARDS: When heated to decomposition this compound emits very toxic fumes of lead, nitrogen oxides and sulfur oxides. Ingestion of alcoholic beverages can result in potentially serious toxic effects after exposure (including topical) of this type of compound. (NTP, 1992)

LEAD DIMETHYLDITHIOCARBAMATE is a organometallic with thio carbamate chelating group. Flammable gases are generated by the combination of thiocarbamates and dithiocarbamates with aldehydes, nitrides, and hydrides. Thiocarbamates and dithiocarbamates are incompatible with acids, peroxides, and acid halides. Organometallics are strongly reactive with many other groups. Incompatible with acids and bases. Organometallics are good reducing agents and therefore incompatible with oxidizing agents. Often reactive with water to generate toxic or flammable gases. Organometallics containing halogens (fluorine, chlorine, bromine, iodine) bonded to the metal typically with generate gaseous hydrohalic acids (HF, HCl, HBr, HI) with water.

Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (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 store this material at 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. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. 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)
