SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Chemical Treatability of Thallium Concentration Process: Activated carbon; Chemical Classification: Metals; Scale of Study: Literature Review; Type of Wastewater Used: Unkown; Results of Study: GAC treatment after time precipitate yielded 84% reduction; /Soluble thallium cmpd/

Chemical Treatability of Thallium; Concentration Process: Chemical Precipitation; Chemical Classification: Metals; Scale of Study: Literature Review; Type of Wastewater Used: Unknown; Results of Study: 54% reduction with lime. /Soluble thallium cmpd/

Chemical Treatability of Thallium; Concentration Process: Chemical Precipitation; Chemical Classification: Metals; Scale of Study: Pilot Scale; Type of Wastewater Used: Synthetic wastewater; Results of Study: 30% reduction with ferric chloride, 31% reduction with aluminum (3 coagulants used: 220 ppm of alum @ pH= 6.4. 40 ppm of ferric chloride @ pH= 6.2, 415 ppm of lime @ pH= 11.5; Chemical coagulation was followed by dual media filtration.) /Soluble thallium cmpd/

If employees' clothing may have become contaminated with soluble thallium compounds, employees should change into uncontaminated clothing before leaving the work premises. Clothing contaminated with soluble thallium compounds should be placed in closed containers for storage until it can be discarded or until provision is made for the removal of soluble compounds from the clothing. If the clothing is to be laundered or otherwise cleaned to remove the soluble thallium compounds, the person perfoming the operation should be informed of soluble thallium compounds's hazardous properties. Non-impervious clothing which becomes contaminated with soluble thallium compounds should be removed promptly and not reworn until the soluble thallium compound is removed from the clothing. /Soluble thallium compounds/

Skin that becomes contaminated with soluble thallium compounds should be promptly washed or showered to remove any soluble thallium compounds. Eating and smoking should not be permitted in areas where soluble thallium compound is handled, processed, or stored. Employees who handle soluble thallium compounds should wash their hands thoroughly before eating, smoking, or using toilet facilities. /Soluble thallium compounds/

Excursion Limit Recommendation: Excursions in worker exposure levels may exceed 3 times the TLV-TWA for no more than a total of 30 minutes during a work day, and under no circumstances should they exceed 5 times the TLV-TWA, provided that the TLV-TWA is not exceeded. /Thallium and soluble cmpds, as Tl/

The following medical procedures should be made available to each employee who is exposed to ... thallium /and thallium/ compounds at potentially hazardous levels: Initial Medical Examination: A complete history and physical examination: The purpose is to detect existing conditions that might place the exposed employee at increased risk, and to establish a baseline for future health monitoring. Examination of the eyes, nervous system, lung, liver, kidneys, gastrointestinal tract, and body hair should be stressed. Urinalysis: Since kidney damage has been observed in humans exposed to thallium, a urinalysis should be obtained to include at a minimum specific gravity, albumin, glucose, and a microscopic /examination/ on centrifuged sediment. Periodic Medical Examination: These medical examinations should be repeated on an annual basis. /Thallium and thallium compounds/
