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.

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.

4.3 Indication of immediate medical attention and special treatment needed, if necessary

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Lead and related compounds/

6.Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures

Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.

6.2 Environmental precautions

Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting.

6.3 Methods and materials for containment and cleaning up

SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.

7.Handling and storage

7.1 Precautions for safe handling

Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.

7.2 Conditions for safe storage, including any incompatibilities

Separated from food and feedstuffs.

8.Exposure controls/personal protection

8.1 Control parameters

Occupational Exposure limit values

NIOSH considers "Lead" to mean metallic lead, lead oxides, and lead salts (including organic salts such as lead soaps but excluding lead arsenate).

Recommended Exposure Limit: 10 hr Time-Weighted Avg: 0.050 mg/cu m /Lead/

Air concentrations should be maintained so that worker blood lead remains less than 0.06 mg Pb/100 g of whole blood. /Lead/

10.3 Possibility of hazardous reactions

Combustible when exposed to heat or flame.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.
