SECTION 4: First aid measures
Description of necessary first-aid measures
Move the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.
Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.
Rinse with pure water for at least 15 minutes. Consult a doctor.
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms/effects, acute and delayed
Non-Specific -- Thallium Salts, n.o.s.) Poisonous if swallowed. Inhalation of dust causes poisoning. (EPA, 1998)
Indication of immediate medical attention and special treatment needed, if necessary
The distribution and elimination patterns of thallous malonate were studied and compared to those of thallous sulfate. Male Syrian golden hamsters were divided into 3 groups. The first group (control) received distilled water. Animals in group 2 received either a single oral dose or an ip dose of 12.5 mg/kg of thallous malonate. The third group of animals received either a single oral dose or an ip dose of 12.35 mg/kg of thallous sulfate. By 1 hour after thallous malonate adminstration, thallium was detected in all organs. Thallium was detected only in the heart, liver and kidney in the group given thallous sulfate. By 12 hours the maximum values, except for muscle and testes, were observed in both treated groups, and the distribution patterns were similar. At this time, although the thallium concentration in the brain was less than in the other organs, thallium was rapidly deposited in the brain in both treated groups. The liver, heart, kidney and whole blood had short half-lives in the alpha phase. The beta phase in these tissues and in the brain, muscle and testes had long half lives, indicating that thallium disappeared slowly from organs. In the group receiving oral thallous malonate the urinary elmination rate constant was 0.175/day, and the fecal rate was 0.500. In the group receiving thallous malonate ip the urinary elimination rate constant was 0.086, and the fecal rate was 0.081. The urinary elimination rate constant in animals treated orally with thallous sulfate was 0.073 and the fecal rate was 0.054. Ip treatment with thallous sulfate resulted in a urinary elimination rate of 0.063 and fecal rate of 0.084. It was concluded that thallous malonate, an organic thallium compound, showed slightly higher elimination rate constants but similar toxicity and distribution patterns to thallous sulfate, an inorganic thallium compound.
SECTION 5: Firefighting measures
Suitable extinguishing media
Water, carbon dioxide, foam, dry chemical. Soluble thallium cmpd
Specific hazards arising from the chemical
Non-Specific -- Thallium Salts, n.o.s.) Fire may produce irritating or poisonous gases. Runoff from fire control or dilution water may cause pollution. (EPA, 1998)
Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting if necessary.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
Environmental precautions
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
Methods and materials for containment and cleaning up
Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
SECTION 7: Handling and storage
Precautions for safe handling
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Store the container tightly closed in a dry, cool and well-ventilated place. Store apart from foodstuff containers or incompatible materials.
SECTION 8: Exposure controls/personal protection
Control parameters
no data available
no data available
Appropriate engineering controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures, such as personal protective equipment (PPE)
Wear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

Chemical stability
no data available
Possibility of hazardous reactions
Salts, basic, such as THALLOUS MALONATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.
