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/

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.

/GUIDE 154: SUBSTANCES - TOXIC AND/OR CORROSIVE (NON-COMBUSTIBLE)/ First Aid: Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. /Cadmium compound/|/GUIDE 154: SUBSTANCES - TOXIC AND/OR CORROSIVE (NON-COMBUSTIBLE)/ Spill or Leak: ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. /Cadmium compound/|/GUIDE 154: SUBSTANCES - TOXIC AND/OR CORROSIVE (NON-COMBUSTIBLE)/ Fire: Small fires: Dry chemical, CO2 or water spray. Large fires: Dry chemical, CO2, alcohol-resistant foam or water spray. Move containers from fire area if you can do it without risk. Dike fire control water for later disposal; do not scatter the material. Fire involving tanks or car/trailer loads: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. /Cadmium compound/|/GUIDE 154: SUBSTANCES - TOXIC AND/OR CORROSIVE (NON-COMBUSTIBLE)/ Evacuation: ...

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 carbonate is included on this list.

The major hazards encountered in the use and handling of cadmium carbonate stem from its toxicologic properties. Toxic primarily by ingestion and inhalation, exposure to this colorless, crystalline substance may occur from its use in lawn and turf fungicides,a catalyst in organic reactions, and as a source of cadmium in the generation of other compounds. Effects from exposure may include headace, shortness of breath, chest pains, kidney damage, liver damage, emphysema, intense pulmonary edema (possibly resulting in death). 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, 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. Cadmium carbonate 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. Wear a self-contained breathing apparatus when fighting such fires. Cadmium carbonate 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 carbonate, consult environmental regulatory agencies for guidance.

SOIL: Cadmium carbonate concentrations ranged from 0.01 to 0.6 mg/kg and 0.01 to 16.6 mg/kg in podzols (pH 4.1-6.5; organic matter 1.3-3.7%) and brown soils (pH 3.7-6.9; organic matter 0.89-5.61%), respectively, from Tarnowskie Gory, Poland. Calcium carbonate is present as 10 and 16%, respectively, of total cadmium(1).

All animals survived treatment and no significant behavioural changes were observed. Cd2+ precipitates completely as cadmium carbonate in the first 72 hr. Nevertheless, metal uptake in the organ was observed beyond this period. After 96 hr an increase in the amount of sulphate mucins and a reduction in intensity of the cytochrome-oxidase reaction were observed. Cadmium toxicity in very hard water is interpreted as being due to cadmium carbonate ingestion which might cause histochamical alterations in the gills.|/AQUATIC SPECIES/ Crassostrea gigas (Pacific oyster) exposed to 20-25 ug/L for 6 days experienced a 50% reduction in settlement; 10 ug/L for 14 days experienced growth reduction. /Conditions of bioassay not specified/|/AQUATIC SPECIES/ Crassostrea virginica (Eastern oyster) exposed to 15 ug/L for 2 days experienced reduction in embryonic development. /Conditions of bioassay not specified/|For more Ecotoxicity Excerpts (Complete) data for CADMIUM CARBONATE (19 total), please visit the HSDB record page.

NIOSH (NOES Survey 1981-1983) has statistically estimated that 164 workers (41 of these were female) were potentially exposed to cadmium carbonate in the US(1).

The cereal crops (barley - Hordeum vulgare L., maize - Zea mays L., wheat - Triticum vulgare L.) were grown in a greenhouse using a sandy soil type treated with various doses of cadmium carbonate (salt), copper carbonate (malachite), lead carbonate (cerussite), and zinc carbonate (smithsonite), added jointly. The following levels of these metals were used: Cd - 5, 10, 50 ug g-1 soil; Cu and Ph-50, 100, 500 ug g-1 soil; Zn-150, 300, 1500 ug g-1 soil. Sequential extraction was adopted to partition the metals into five operationally-defined fractions: exchangeable, carbonate, Fe-Mn oxides, organic, and residual. The residual was the most abundant fraction in the untreated (control) soil for all the metals studied (50 to 60% of the total metal content). The concentrations of exchangeable Cd, Cu, Pb, and Zn were relatively low in untreated soil but increased (over the three year period) in treated soils for Cd, Zn, and Cu, whereas only small changes were observed for Pb. This experiment showed a significant increase in Cd, Zn, and Cu in tissue of plants grown on the treated soil, but a non-significant change in plant tissue with respect to Pb concentration.

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Cadmium and Related Compounds/|Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary.
