The New Jersey Worker and Community Right to Know Act requires public and private employers to provide information about hazardous substances at their workplaces. (N.J.S.A. 34:5A-1 et. seq.)

A severe skin, eye, and respiratory tract irritant; May cause burns; [HSDB] An irritant; Harmful by ingestion and inhalation; [MSDSonline] See Bromine. See Cadmium and the linked diseases.

The major hazards encountered in the use and handling of cadmium bromide stem from its toxicologic properties. Toxic primarily by ingestion and inhalation, exposure to this odorless, white-to-yellowish, crystalline substance may occur from its use in photography, process engraving, and lithography. Effects from exposure may include contact burns to the skin, headace, shortness of breath, chest pains, kidney damage, emphysema, and chronic bronchitis. Processes and operations which may release cadmium fumes or dust should be enclosed and fitted with exhaust ventilation. In activities where over-exposure is possible, workers should wear a high efficiency particulate filter respirator or self-contained breathing apparatus. Protective clothing also should be worn, including eye and face protection, and rubber gloves. 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. Cadmium bromide presents only a moderate fire hazard (when in the form of dust) if exposed to heat, flame, or by chemical reaction with oxidizing agents, metals, hydrogen azide, zinc, selenium, or tellurium. For small fires involving cadmium bromide, extinguish with dry chemical, CO2, Halon, water spray, or standard foam, and for large fires, use water spray, fog, or standard foam. Wear a self-contained breathing apparatus when fighting such fires. Cadmium bromide should be stored in cool, well-ventilated areas, out of direct rays of the sun, and away from fire hazards. Small spills of cadmium bromide should be collected in containers for latter disposal (liquids are first absorbed by sand or other noncombustible material). Large spills of cadmium bromide (solution) should be contained in an excavated pit or other holding area, and surface runoff diked to prevent its escape. Solids should be covered with a plastic sheet. For large spills into bodies of water, first neutralize with agricultural lime, crushed limestone, or sodium bicarbonate, then use mechanical dredges or lifts to remove immobilized masses and precipitates. Before implementing land disposal of waste cadmium bromide, consult environmental regulatory agencies for guidance.

CADMIUM BROMIDE has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.

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 bromide is included on this list.

EYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.

Chronic exposure to cadmium fumes can cause chemical pneumonitis, pulmonary edema, and lung diseases such as bronchitis and emphysema. Cadmium also accumulates in the kidneys, causing permanent damage. Loss of bone density also occurs. Bromine vapour causes irritation and direct damage to the mucous membranes. Elemental bromine also burns the skin. The bromide ion is a central nervous system depressant and chronic exposure produces neuronal effects. This is called bromism and can result in central reactions reaching from somnolence to coma, cachexia, exicosis, loss of reflexes or pathologic reflexes, clonic seizures, tremor, ataxia, loss of neural sensitivity, paresis, papillar edema of the eyes, abnormal speech, cerebral edema, delirium, aggressiveness, and psychoses. (L625, L626, L627, L6)

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. Bromine is a powerful oxidizing agent and is able to release oxygen free radicals from the water in mucous membranes. These free radicals are also potent oxidizers and produce tissue damage. In additon, the formation of hydrobromic and bromic acids will result in secondary irritation. The bromide ion is also known to affect the central nervous system, causing bromism. This is believed to be a result of bromide ions substituting for chloride ions in the in actions of neurotransmitters and transport systems, thus affecting numerous synaptic processes.

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. Bromine is mainly absorbed via inhalation, but may also enter the body through dermal contact. Bromine salts can be ingested. Due to its reactivity, bromine quickly forms bromide and may be deposited in the tissues, displacing other halogens. (L626, L6)
