Indication of any immediate medical attention and special treatment needed
Absorption, Distribution and ExcretionStudies on hamsters indicate that about one-third of inhaled cobalt oxide is absorbed. Twenty-four hr after inhalation of 0.8 mg of cobalt oxide, 23% was recovered in the carcass, 3% in the lung, and 0.5% in the liver and kidney together. Of the inhaled amt, 60% of the CoO (cobaltous oxide) was recovered in the GI tract. Possibly the amt of cobalt recovered in the GI was cleared from the lung since GI excretion of parenterally admin cobalt is comparably low. On the other hand, studies on rats show that the pulmonary absorption of inhaled cobaltous oxide may be considerably less. Intratracheally instilled cobaltous oxide (1.5 ug) was retained in the lung for a relatively long period with a half-time of about 15 days. This indicates that the pulmonary absorption of cobalt oxide is a slow process.

Disposal methods
ProductThe material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
