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.

NIOSH considers nickel metal and other compounds (as Ni) to be a potential occupational carcinogen. /Nickel metal and other compounds (as Ni)/|NIOSH usually recommends that occupational exposures to carcinogens be limited to the lowest feasible concentration. /Nickel metal and other compounds (as Ni)/|Recommended Exposure Limit: 10 Hr TWA 0.015 mg/cu m. /Nickel metal and other compounds (as Ni)/

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. Basic nickel(II) carbonate is included on this list.

... Nickel carbonate is insoluble in water. ... Respiratory absorption with secondary gastrointestinal absorption of nickel (insoluble compounds) is the major route of entry during occupational exposure. Percutaneous absorption is negligible, quanitatively, but is important in the pathogenesis of contact hypersensitivity. Absorption is related to the solubility of the compound /and nickel carbonate is classified as an insoluble salt/. Nickel carbonate ... induced local mesenchymal tumors in a variety of experimental animals after im, sc, ip, intrapleural, intraocular, intraosseous, intrarenal, intra-articular, intratesticular or intra-adipose administration.

Nickel carbonate occurs in nature as the mineral zaratite, NiCO3.2Ni(OH)2.4H2O. It is formed by the decomposition of nickel carbonyl in moist air and is a potential atmospheric and surface water pollutant.

Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilation if necessary. Administer oxygen by nonrebreather mask at 10 t0 15 L/min. Monitor for shock and treat if necessary ... . Monitor for pulmonary edema and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool ... . /Nickel and related compounds/|Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious. Positive pressure ventilation techniques with a bag valve mask device may be beneficial. Monitor cardiac rhythm and treat arrhythmias if necessary ... . Consider drug therapy for pulmonary edema ... . Start an IV with D5W /SRP: "To keep open", minimal flow rate/. Use lactated Ringer's if signs of hypovolemia are present. For hypotension with signs of hypovolemia, administer fluid cautiously. Consider vasopressors for hypotension with a normal fluid volume. Watch for signs of fluid overload ... .

ONLY BASIC NICKEL CARBONATE (2NICO3.3NI(OH)2.4H2O) IS PRODUCED COMMERCIALLY. IT IS LARGELY PRODUCED & CONSUMED DURING THE MFR OF NICKEL OXIDE, NICKEL POWDER & NICKEL CATALYSTS. CANADA IS THE LARGEST SINGLE PRODUCER ...|USA CONSUMPTION OF BASIC NICKEL CARBONATE IS LARGELY IN THE PRODUCTION OF NICKEL CATALYSTS FOR USE IN ORG CHEMICAL MFR, PETROLEUM REFINING & EDIBLE OIL HARDENING. A HIGH PURITY BASIC NICKEL CARBONATE IS USED IN ELECTRONIC COMPONENTS SUCH AS FERRITES & THERMISTORS.
