A skin and eye irritant; Toxic by ingestion and inhalation--may cause injury to kidneys and lungs; [HSDB] Causes burns and lacrimation; May be absorbed through skin; Targets lungs, kidneys, and liver; Inhalation may cause chemical pneumonitis; [MSDSonline] See Boric acid. See Potassium tetrafluoroborate. See Cadmium and the linked occupational diseases.

The major hazards encountered in the use and handling of cadmium fluoborate stem from its toxicologic properties. Toxic primarily by ingestion and inhalation, exposure to this odorless, colorless fluid may occur from its use in electroplating. Effects from exposure may include irritation to the skin and eyes, renal damage, and respiratory damage (including emphysema and chronic bronchitis) from aerosolized material. In activities where exposure is possible, workers should wear a self-contained breathing apparatus. Protective clothing also should be worn, including eye, face, and hand protection. All such clothing should be removed before leaving work. If contact should occur, immediately wash contaminated skin with large amounts of water. Do not eat, smoke, or drink in work areas. While cadmium fluoborate is not considered to be flammable, fires involving the substance may produce toxic hydrogen fluoride and cadmium oxide fumes. Wear a self-contained breathing apparatus when fighting such fires. Cadmium fluoborate should be stored in cool, well-ventilated areas, out of direct rays of the sun, and away from fire hazards. Before implementing land disposal of waste cadmium fluoborate, consult environmental regulatory agencies for guidance.

National Toxicology Program. Eleventh Report on Carcinogens (2005). The Report on Carcinogens is an informational scientific and public health document that identifies and discusses substances (including agents, mixtures, or exposure circumstances) that may pose a carcinogenic hazard to human health. Cadmium and Cadmium Compounds are listed as known to be human carcinogens. /Cadmium and Cadmium Compounds/[Available from, as of July 31, 2009: http://ntp.niehs.nih.gov/ntp/roc/eleventh/profiles/s028cadm.pdf]

CADMIUM FLUOROBORATE acts as a weakly acidic inorganic salt, which is soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

Listed as a hazardous air pollutant (HAP) generally known or suspected to cause serious health problems. The Clean Air Act, as amended in 1990, directs EPA to set standards requiring major sources to sharply reduce routine emissions of toxic pollutants. EPA is required to establish and phase in specific performance based standards for all air emission sources that emit one or more of the listed pollutants. Cadmium fluoborate is included on this list.

Biological Exposure Indices (BEI) [ACGIH] - Cd in urine = 5 ug/g creatinine; Cd in blood = 5 ug/L; sampling time not critical; Monitoring in blood should be preferred during the initial year of exposure and whenever changes in the degree of exposure are suspected. [ACGIH]

If material on fire or involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use water in flooding quantities as fog. Use "alcohol" foam, dry chemical or carbon dioxide. /Cadmium compounds, NOS/

Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number D006, must conform with USEPA regulations in storage, transportation, treatment and disposal of waste.

Activated carbon adsorption process is used in the removal of cadmium from two types of synthetic cadmium plating wastewaters, specifically cadmium (2+) tetrafluoborate and cadmium (2+) cyanide solutions. Results indicate that the acidic activated carbons, Nuchar SA and Nuchar SN have the highest cadmium (2+) removal potential. Recommendations include the need to specifically identify the chemical make-up of each wastewater stream and run an individual experiment for finding the best treatment method. Graphs show the effects of carbon type on cadmium (2+) removal, adsorption characteristics of cadmium (2+) from synthetic cadmium (2+)-tetrafluoroborate wastewater in relation to pH and numerous cadmium concentrations, and also show the adsorption characteristics of cadmium (2+) from another wastewater, cadmium (2+) cyanide.

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.

SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

Cadmium fluoborate may be dangerous if it enters water intakes; notify local health and wildlife officials and operators of nearby water intakes.

SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. All contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.

Cadmium initially binds to metallothionein and is transported to the kidney. Toxic effects are observed once the concentration of cadmium exceeds that of available metallothionein, and it has also been shown that the cadmium-metallothionein complex may be damaging. Accumulation of cadmium in the kidney results in increased excretion of vital low and high weight molecular proteins. Cadmium is a high affinity zinc analog and can interfere in its biological processes. It also binds to and activates the estrogen receptor, likely stimulating the growth of certain types of cancer cells and causing other estrogenic effects, such as reproductive dysfunction. Cadmium causes cell apoptosis by activating mitogen-activated protein kinases. (L8, A18, A19, A28)

Evaluation: There is sufficient evidence in humans for the carcinogenicity of cadmium and cadmium compounds. There is sufficient evidence in experimental animals for the carcinogenicity of cadmium compounds. There is limited evidence in experimental animals for the carcinogenicity of cadmium metal. In making the overall evaluation, the Working Group took into consideration the evidence that ionic cadmium causes genotoxic effects in a variety of types of eukaryotic cells, including human cells. Overall evaluation: Cadmium and cadmium compounds are carcinogenic to humans (Group 1). /Cadmium and cadmium compounds/

CLASSIFICATION: B1; probable human carcinogen. BASIS FOR CLASSIFICATION: Limited evidence from occupational epidemiologic studies of cadmium is consistent across investigators and study populations. There is sufficient evidence of carcinogenicity in rats and mice by inhalation and intramuscular and subcutaneous injection. Seven studies in rats and mice wherein cadmium salts (acetate, sulfate, chloride) were administered orally have shown no evidence of carcinogenic response.

Cadmium is absorbed from oral, inhalation, and dermal routes. Cadmium initially binds to metallothionein and albumin and is transported mainly to the kidney and liver. Toxic effects are observed once the concentration of cadmium exceeds that of available metallothionein, and it has also been shown that the cadmium-metallothionein complex may be damaging. Cadmium is not known to undergo any direct metabolic conversion and is excreted unchanged, mainly in the urine. (L6)
