8.2 Exposure controls
Appropriate engineering controls
Avoid contact with skin, eyes and clothing. Wash hands before breaks and immediately after handling the product.
Personal protective equipment
Eye/face protection
Face shield and safety glasses Use equipment for eye protection tested and approved under appropriate
government standards such as NIOSH (US) or EN 166(EU).
Skin protection
Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without
touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after
use in accordance with applicable laws and good laboratory practices. Wash and dry hands.
Body Protection
Complete suit protecting against chemicals, The type of protective equipment must be selected according to
the concentration and amount of the dangerous substance at the specific workplace.
Respiratory protection
Where risk assessment shows air-purifying respirators are appropriate use a full-face particle respirator type
N100 (US) or type P3 (EN 143) respirator cartridges as a backup to engineering controls. If the respirator is the
sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and
approved under appropriate government standards such as NIOSH (US) or CEN (EU).
Control of environmental exposure
Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the
environment must be avoided.

Additional Information
RTECS: Not available
The most characteristic symptom of thallium exposure is alopecia (loss of hair). Cutaneous effects may include dry,
scaly skin and impairment of nail growth often resulting in the appearance of crescent-shaped strips across fingernails
and toenails (Mees' line). Other symptoms in acute poisoning relate chiefly to the gastrointestinal tract, nervous
system, skin, eyes, and cardiovascular system. Acute poisoning results in swelling of the feet and legs, arthralgia,
vomiting, insomnia, hyperesthesia and paresthesia of the hands and feet, mental confusion, polyneuritis with severe
pain in the legs and loins, partial paralysis of the legs, angina-like pains, nephritis, wasting and weakness, and
lymphocytosis and eosinophilia. In chronic poisoning, central and peripheral nervous system abnormalities may persist
including ataxia, tremor, incoordination, paralysis of extremities, endocrine disorders, memory loss, and psychoses
may develop., To the best of our knowledge, the chemical, physical, and toxicological properties have not been
thoroughly investigated.
